About This Guide

This Sun Storage 2500-M2 Arrays Hardware Installation Guide describes how to install
array trays in a cabinet, physically set up and connect your array to a host, apply
power and to add network functionality, including storage management
(multipath/failover), IP addressing, and DHCP.

The terminology used in this document refers to the Sun Storage 2500-M2 Arrays.
There are two styles of controller trays, each with different host interface ports (SAS
or FC). There is also the expansion tray, which enables the Sun Storage 2500-M2
Arrays to have more disk drives attached. The components that slide into the trays
are called customer replaceable units (CRUs) or modules.

Array management, data host management, and remote command line interface
(CLI) functions are performed by the Sun Storage Common Array Manager (CAM)
software. For installation and initial configuration of the array, including firmware
upgrades, initial array setup, partitioning domains, configuring storage, and
configuring IP addressing, see the Sun Storage Common Array Manager Installation and
Setup Guide.

Before You Begin

Refer to the following documents to make sure physical dimensions, service
clearances, and power connections are ready for the installation of the array.

About Sun Storage 2500-M2 Trays

The Sun Storage 2540-M2 FC array, Sun Storage 2530-M2 SAS array, and the Sun
Storage 2501-M2 array expansion tray are a family of storage products that provide
high-capacity, high-reliability storage in a compact configuration.

The controller tray, with two controller modules, provides the interface between a
data host and the disk drives. The Sun Storage 2540-M2 FC array provides a Fibre
Channel (FC) connection between the data host and the controller tray. The Sun
Storage 2530-M2 SAS array provides a Serial Attached SCSI (SAS) connection
between the data host and the controller tray.

The Sun Storage 2500-M2 Arrays are modular, rack-mountable controller trays. The
arrays are scalable from a single controller tray configuration to a maximum
configuration of one controller tray and three additional expansion trays. One
controller tray and three expansion trays creates a storage array configuration with a
total of 48 drives.

2 Hardware Installation Guide • June 2011

The Sun Storage 2501-M2 array expansion tray provides additional storage. You can
attach the expansion tray to either of the Sun Storage 2500-M2 Arrays. Controller
trays and expansion trays can be installed in industry-standard cabinets.

Use Sun Storage Common Array Manager to manage the array. See Sun Storage
Common Array Manager documentation for more information.

Caution – Possible hardware damage—To prevent electrostatic discharge damage

to the tray, use proper antistatic protection when handling tray components.

Sun Storage 2500-M2 Controller Trays

Two types of controller trays are offered:

■ Sun Storage 2540-M2 Fibre Channel (FC) Array

■ Sun Storage 2530-M2 Serial Attached SCSI (SAS) Array

TABLE 1-1 describes the features of the FC and SAS controller trays.

Sun Storage 2501-M2 Expansion Tray

The expansion tray expands the capacity of a storage array. The controllers in the
controller tray connect to the expansion tray and access the disk drives in the
expansion tray for additional storage. An expansion tray contains both physical
components (disk drives, input/output modules (IOMs), and power-fan modules)
and logical components (virtual disks and volumes).

Important Information About DC Power Option

You can order an optional DC power supply connection and connector cables for the
drive tray. A qualified service person is required to make the DC power connection
per NEC and CEC guidelines. A two-pole, 30-amp circuit breaker is required
between the DC power source and the drive tray for over-current and short-circuit
protection. Before turning off any power switches on a DC-powered expansion tray,
you must disconnect the two-pole, 30-amp circuit breaker.

Caution – Risk of electrical shock—This unit has more than one power source. To

remove all power from the unit, all DC MAINS must be disconnected by removing
all power connectors from the power supplies.

Controller Tray Host Ports

FIGURE 1-7 Sun Storage 2530-M2 Array SAS Ports—Rear View

1 SAS host ports 2 SAS expansion port

Chapter 1 Installing Sun Storage 2500-M2 Arrays 9

FIGURE 1-8 Sun Storage 2540-M2 Arrays FC Ports—Rear View

Note – Four Small Form-factor Pluggable (SFP) transceivers are shipped with the

Sun Storage 2540-M2 FC controller tray, providing support for two FC ports per
controller module, or four FC ports per controller tray.

Note – The SAS host ports on the 2540-M2 FC controller tray are not for use and not

supported.

SFP Transceivers

The controller tray supports Fibre Channel (FC) and SAS drive connections. FC host
connections can operate at 8 Gb/s or at a lower data rate. Ports for 8-Gb/s Fibre
Channel host connections require SFP transceivers designed for this data rate. These
SFP transceivers look similar to other SFP transceivers but are not compatible with
other types of connections.

Note – The SFP transceiver shown might look different from those that are shipped

with your controller tray. The difference does not affect transceiver performance.

Caution – Risk of exposure to laser radiation—Do not disassemble or remove any

part of a Small Form-factor Pluggable (SFP) transceiver because you might be
exposed to laser radiation.

1 FC host ports 2 SAS expansion port

10 Hardware Installation Guide • June 2011

FIGURE 1-9 SFP Transceiver for the Sun Storage 2540-M2 FC Array

Note – On the Sun Storage 2530-M2 controller tray, each controller module has a

pair of levers with handles for removing the component from the tray. One of these
handles on each controller module is located next to a host port. The close spacing
between the handle and the host port might make it difficult to remove a cable that
is attached to the host port. If this problem occurs, use a flat-blade screwdriver to
push in the release component on the cable connector.

Power-Fan Modules

The power-fan module for the Sun Storage 2540-M2 FC array, Sun Storage 2530-M2
SAS array, and Sun Storage 2501-M2 array expansion tray is identical and
interchangeable.

Note – A minimum of two disk drives must be operating in a controller tray or in

an expansion tray to avoid generating a power-fan module error.

The power-fan module contains an integrated cooling fan. The power supply
provides power to the internal components by converting incoming AC voltage to
DC voltage. The fan circulates air inside of the tray by pulling air in through the
vents on the front of the module and pushing the air out of the vents on the back of
each fan.

Each tray contains two power-fan modules. If one power supply is turned off or
malfunctions, the other power supply maintains electrical power to the tray.
Likewise, the fans provide redundant cooling. If one of the fans in either fan housing
fails, the remaining fan continues to provide sufficient cooling to operate the tray.
The remaining fan runs at a higher speed until the failed fan is replaced. Replace the
failed fan as soon as possible.

1 Active SFP transceiver 2 Fiber-optic cable

Chapter 1 Installing Sun Storage 2500-M2 Arrays 11

Expansion Tray IOM

The expansion tray contains two input/output modules (IOMs) that provide the
interface between the disk drives in the expansion tray and the controllers in the
controller tray. Each controller module in the controller tray connects to an IOM.

If one IOM fails, the other IOM provides a redundant data path to the disk drives.
You can replace a failed IOM while the power to the storage array is turned on and
the storage array is processing data (a hot swap).

For IOM replacement procedures, see the Service Advisor feature of Sun Storage
Common Array Manager.

Service Action LEDs

Each controller, power-fan module, IOM, and disk drive has a Service Action
Allowed LED. The Service Action Allowed LED indicates when you can remove a
component safely.

For a description of each LED, see:

■ “LED Symbols and General Behavior” on page 45

■ “Disk Drives LEDs” on page 48

■ “Controller Tray and Expansion Tray LEDs” on page 49

Caution – Potential loss of data access—Never remove a power-fan module, a

controller module, or a disk drive unless the Service Action Allowed LED is turned
on or you are given specific instructions to do so by the Service Advisor feature of
the Sun Storage Common Array Manager.

If a CRU or module fails and must be replaced, the Service Action Required LED on
that module turns on to indicate that a service action is required. The Service Action
Allowed LED turns on if it is safe to remove the CRU or module. If there are data
availability dependencies or other conditions that dictate that a CRU or module
should not be removed, the Service Action Allowed LED remains off.

The Service Action Allowed LED automatically turns on or turns off as conditions
change. In most cases, the Service Action Allowed LED turns on when the Service
Action Required (Fault) LED is turned on for a CRU or module.

12 Hardware Installation Guide • June 2011

Note – If the Service Action Required (Fault) LED is turned on but the Service

Action Allowed LED is turned off for a particular CRU or module, you might have
to service another component first. Check the Service Advisor feature of Sun Storage
Common Array Manager to determine the action you should take.

Disk Drives

Controller trays or expansion trays hold up to 12 disk drives, for a maximum of 48
disk drives in a storage array. To reach the maximum of 48 disk drives, the storage
array must consist of one controller tray and three expansion trays.

Access to disk drives is from the front of the tray.

Disk drives can be mixed, provided you adhere to these additional rules:

■ Use the same drive types within a virtual disk

■ Assign hot spares to cover any disk drive failure

FIGURE 1-10 Disk Drives

Refer to the release notes for your array for supported drives.

Disk drives for the Sun Storage 2500-M2 Arrays have three components:

■ Hard drive

■ Hard drive carrier

■ Adapter card for connecting the disk drive to the mid-plane

1 Left end cap (with drive tray LEDs) 3 Right end cap

2 Drives

Chapter 1 Installing Sun Storage 2500-M2 Arrays 13

The physical locations of the disk drives are numbered 1 through 12, from left to
right, and from top to bottom. The right end cap has numbers on the side showing
the numbers of the adjacent drives. The Service Advisor feature of Sun Storage
Common Array Manager automatically detects a disk drive’s tray ID and slot
designation.

Array Management Software

The Sun Storage 2500-M2 Arrays are managed by Sun Storage Common Array
Manager. The array management software provides:

■ Web browser–based management and configuration from an external

management host

■ Data host software that controls the data path between the data host and the array

■ Remote command-line interface (CLI) client that provides the same control and

monitoring capability as the web browser, and is scriptable for running frequently
performed tasks

■ Service Advisor, an online reference of hardware and software configuration and

troubleshooting information and procedures.

For information about installing the array management software and configuring
and managing the array, see the Sun Storage Common Array Manager Installation and
Setup Guide and the Sun Storage Common Array Manager Administration Guide.

14 Hardware Installation Guide • June 2011

Service Advisor and CRUs

Note – The replaceable components inside the controller tray or expansion tray are

referred to as either customer replaceable units (CRUs) or as modules.

The majority of replaceable units are designed to be replaceable by customers.

To see a list of the hardware components that can be replaced at the customer site,
refer to Service Advisor in Sun Storage Common Array Manager.

(for either SAS or FC host connections) in each host. Using both ports of a dual­port HBA or a dual-port NIC provides two paths to the storage array but does not
ensure redundancy if an HBAfails.

■ Refer to the Sun Storage 2500-M2 Arrays Release Notes for information about the

supported models of the HBAs and their requirements.

■ Most of the HBAs, as shipped from the vendor, require updated firmware and

software drivers to work correctly with the storage array. For information about
the updates, refer to the website of the HBA vendor.

Installing Host Bus Adapters

1. Check the Sun Storage 2500-M2 Arrays Release Notes to be sure you have a
supported configuration.

2. Install your HBA according to the vendor documentation.

3. Install the latest version of the firmware for the HBA. You can find the latest
version of the firmware for the HBA at the HBA vendor website.

4. Reboot or start your host.

5. While your host is booting, look for the prompt to access the HBA BIOS utility.

6. Select each HBA to view its HBA host port World Wide Name (WWN).

Chapter 2 Installing Switches and HBAs 17

7. Record the following information for each host and for each HBA connected to
the storage array. A label is important if you need to disconnect cables for any
reason. Include the following information:

■ Name of each host

■ HBAs in each host

■ HBA host port World Wide Name (WWN) of each port on the HBA

The following table shows examples of the host and HBA information that you
need to record.

Installing Trays

Use the procedures in this chapter to install controller and expansion trays in an
industry-standard cabinet. The number of trays you need to install depends on your
overall storage requirements. You can install a maximum of four trays, one controller
tray and up to three expansion trays for each array.

■ “Preparing for Installation” on page 19

■ “Installing Adjustable Support Rails” on page 20

■ “Installing Controller and Expansion Trays” on page 23

■ “Connecting the Controller Tray to Expansion Trays” on page 24

Preparing for Installation

Prerequisite: Refer to the Sun Storage 2500-M2 Site Preparation Guide for important
considerations about cabinet installation.

Check the following cabinet requirements:

1. Cabinet is in the final location.

2. Cabinet installation site meets the clearance requirements.

■ Front clearance: 30 in. (76 cm)

■ Back clearance: 24 in. (61 cm)

3. Lower the feet on the cabinet, if required, to keep it from moving.

4. Combined power requirements of the trays do not exceed the power capacity of
your cabinet.

20 Hardware Installation Guide • June 2011

Note – The power supplies meet standard voltage requirements for both domestic

and worldwide operation.

Installing Adjustable Support Rails

This procedure describes how to install adjustable support rails for Oracle’s Sun
Storage 2500-M2 array hardware.

The adjustable support rail kit includes these parts:

■ Eight large screws for mounting the support rails and the front of the tray to the

cabinet

■ Eight washers for the large screws

■ Eight large spacers for cabinets with square holes (Note: Small spacers for round

holes come pre-installed in the rails)

■ Two small screws for securing the rear of the tray to the support rails

Preparing to Install the Support Rails in the
Cabinet

FIGURE 3-1 shows how the support rails are positioned inside the cabinet. Note the

following clearance requirements:

■ If you are installing the support rails above an existing tray, position the rails

directly above the tray.

■ If you are installing the support rails below an existing tray, allow 3.5 in. (8.8 cm)

clearance for 2U controller tray or expansion tray units.

Attaching the Support Rails to the Cabinet

FIGURE 3-2 Attaching the Support Rails to the Cabinet

1. If desired, use alignment spacers on the flanges of the mounting rails.

The alignment spacers are designed to fit into the mounting holes in the cabinet
and help position and hold the mounting rails. Each support rail comes with two
spacers in the front bracket and two spacers in the rear bracket.

■ If the cabinet has round holes, use the pre-installed small spacers on the front

and rear of the support rail.

■ If the cabinet has square holes, replace the small spacers on the front and rear

of the support rail with the large spacers that come with the rail kit.

2. Be sure the adjustment screws on the support rail are loose so you can extend
or contract the support rail as needed.

3. Place the support rail inside the cabinet and extend the support rail until its
flanges touch the inside of the cabinet.

1 Cabinet mounting holes 3 Support rails

2 Adjustment screws for locking the support rail

4 Clip for securing the rear of the tray

Chapter 3 Installing Trays 23

4. Insert one large screw through the front of the cabinet and screw into the upper
captured nut in the support rail. If needed, add a washer between the screw
and the cabinet rail. Tighten the screw.

Note – Do not insert a screw into the front lower captured nut at this time. This

captured nut is used for tray installation.

5. Insert two large screws through the rear of the cabinet and screw into the upper
and lower captured nuts in the rear flange in the support rail. If needed, add a
washer between each screw and the cabinet rail. Tighten the screws.

6. Tighten the adjustment screws on the support rail.

7. Repeat Step 1 through Step 6 for the second support rail.

Installing Controller and Expansion
Trays

When installing trays, distribute tray weight evenly within the cabinet. One
approach is to install the controller tray in the middle portion of the cabinet while
allowing room for expansion trays to be placed above and below the controller tray.

Caution – Risk of bodily injury—If the bottom half of the cabinet is empty, do not

install components in the top half of the cabinet. If the top half of the cabinet is too
heavy for the bottom half, the cabinet might fall and cause bodily injury. Always
install a component in the lowest available position in the cabinet.

1. Install a pair of mounting rails in the cabinet for each controller tray and
expansion tray (see “Installing Adjustable Support Rails” on page 20).

Caution – Possible hardware damage—To prevent electrostatic discharge damage

to the tray, use proper antistatic protection when handling tray components.

2. Using two people, carefully lift and rest the tray on the bottom left and right
rails.

Caution – Risk of bodily injury—A fully loaded controller tray weighs

approximately 60 lbs (27 kg). Two people are required to safely lift the component.

24 Hardware Installation Guide • June 2011

3. Carefully slide the tray into the cabinet until the front mounting flanges on the
tray touch the vertical face of the cabinet and the rear edges of the tray fit into
the clips on the support rails. The tray is correctly aligned when these
conditions are met:

■ The middle mounting holes on the front flanges of the tray align with the

mounting holes on the front of the mounting rails.

■ The rear edge of the tray sheet metal fits into the clip on the mounting rail.

■ The holes in the tray sheet metal for the rear hold-down screws align with the

captured nuts in the side of the mounting rails.

4. Secure the front of the tray to the cabinet by inserting a screw through the
center hole in each front mounting flange. If you used a washer for the top
mounting rail screw, insert a washer between the mounting flange and the
cabinet rail. Tighten the screws.

5. Secure the rear side of the tray to each mounting rail by inserting one screw
through the side sheet metal of the tray into the captured nut on the mounting
rail. Tighten the screw.

6. Replace the end caps that cover the mounting flanges on the front of the tray.

7. Verify that the tray power switches and cabinet circuit breakers are turned off.

8. Connect each tray power supply to a separate power source in the cabinet.

Connecting the Controller Tray to
Expansion Trays

■ Each expansion tray can contain a maximum of twelve drives.

■ The maximum number of drive slots in the storage array is 48.

■ The IOMs in an expansion tray contain two sets of In ports and one set of Out

ports.

■ Each controller module has one dual-ported SAS expansion port to connect to the

expansion trays.

■ To maintain data access in the event of the failure of a controller, an IOM, or a

drive channel, you must connect an expansion tray or a string of expansion trays
to both drive channels on a redundant path pair.

28 Hardware Installation Guide • June 2011

2. If there is a black, plastic plug in the SAS expansion port on the controller,
remove it.

3. Insert one end of the cable into the SAS expansion port on the controller into
slot A of the controller tray.

4. Insert the other end of the cable into the port with an up arrow on the IOM into
slot A of the expansion tray.

5. Are you adding more expansion trays?

■ Yes – Go to Step 6.

■ No – Go to Step 9.

Note – Each IOM in an expansion tray has three SAS expansion ports: two on the

left-center of the IOM and one on the upper-right side. When connecting from an
IOM in one expansion tray to an IOM in another expansion tray, connect the port on
the upper-right to one of the ports on the left-center. The following figure shows
these arrows on an IOM. If the cable is connected either between the two left-center
IOM ports or between two upper-right IOM ports, communication between the two
expansion trays is lost.

Note – It does not matter which of the two left-center IOM ports you use to connect

to the SAS expansion port on the far-right side.

FIGURE 3-8 Connecting a Cable from One IOM to a Second IOM

6. In the IOM of the first expansion tray, insert one end of the cable into the port
on the far-right side.

7. In the IOM of the next expansion tray, insert the other end of the cable into one
of the ports in the left-center of the IOM.

Chapter 3 Installing Trays 29

8. Repeat Step 6 and Step 7 for each expansion tray that you add to the storage

array.

9. To each end of the cables, attach a label with this information:

■ Controller ID (for example, controller A)

■ IOM ID (for example, IOM A)

■ IOM port (In or Out)

■ Expansion tray ID

For example, if you are connecting controller A to the In port on IOM A in
expansion tray 1, the label on the controller end of the cable will have this
information:

CtA-Dch1, Dm1-IOM_A (left), In – Controller End

The label on the expansion tray end of the cable will have this information:

Dm1-IOM_A (left), In, CtrlA

10. Repeat Step 2 through Step 9 for the controller in slot B in the controller tray.

Note – To connect cables for maximum redundancy, the cables attaching controller

B must be connected to the expansion trays in the opposite tray order as for
controller A. That is, the last expansion tray in the chain from controller A must be
the first expansion tray in the chain from controller B.

Connecting Hosts

This chapter describes how to connect a management host and data hosts to Sun
Storage 2500-M2 Arrays. It contains the following sections:

■ “Configuring Out-of-Band Management” on page 31

■ “Configuring In-Band Management” on page 32

■ “Connecting Data Hosts” on page 33

Configuring Out-of-Band Management

Caution – Risk of security breach—Connect the Ethernet ports on the controller

tray to a private network segment behind a firewall. If the Ethernet connection is not
protected by a firewall, your storage array might be at risk of being accessed from
outside of your network.

About Out-of-Band Management

Out-of-band management is a method to manage a storage array in which a storage
management station sends commands to the storage array through the Ethernet
connections on the controller.

■ The Ethernet connections are intended for out-of-band management.

Note – Ethernet port 2 on each controller is reserved for the support representative.

32 Hardware Installation Guide • June 2011

■ In limited situations in which the management host is connected directly to the

controller tray, you must use an Ethernet crossover cable. An Ethernet crossover
cable is a special cable that reverses the pin contacts between the two ends of the
cable.

Connecting Cables for Out-of-Band Management

Perform these steps to connect Ethernet cables for out-of-band management. If you
use only in-band management, skip these steps.

1. Connect one end of an Ethernet cable into the Ethernet port 1 on controller A.

Note – Use only Ethernet port 1 to connect to a management host. Ethernet port 2 is

reserved for the support representative.

2. Connect the other end to the applicable network connection.

3. Repeat Step 1 and Step 2 for controller B.

Configuring In-Band Management

About In-Band Management

An in-band connection uses the data path between the array and host for
management traffic. In-band communicates the management and control commands
on the same path as the data being processed. You configure in-band management
using a Fibre Channel (FC) connection between a data host and the array.

Connecting Cables for In-Band Management

1. Install CAM software on at least one of the network-attached hosts. See the Sun
Storage Common Array Manager Installation and Setup Guide for installation

instructions.

2. Connect two in-band FC cables between HBAs on the data host and the array
(one cable to each controller). You can connect the data host HBAs directly to
the array or through FC switches.

Chapter 4 Connecting Hosts 33

Note – Sun Storage Common Array Manager supports Solaris Sparc and x86,

Windows, and Linux platforms for in-band management. For Red Hat Enterprise
Linux OS, Release 5.1 or higher is required. Check the Sun Storage Common Array
Manager Release Notes, for the latest list of packages to install.

3. Refer to “Configuring In-Band Management for RAID Arrays,” in the Sun
Storage Common Array Manager Installation and Setup Guide for information about

installing the RAID Proxy Agent.

Connecting Data Hosts

Data transmission between the host and the controllers in the array is through Fibre
Channel (FC) or Serial Attached SCSI (SAS) cables. SAS connections from the host to
the controllers are direct connections, and FC connections are direct or through a FC
switch.

About Host Ports

Caution – Possible hardware damage—To preventelectrostatic discharge damage to

the tray, use proper antistatic protection when you handle tray components.

Each controller tray has from four or eight host ports.

■ Sun Storage 2530-M2 array has four SAS-2 host ports (two per controller module)

supporting 6-Gb/s data rates.

■ Sun Storage 2540-M2 array has eight Fibre Channel host ports (four per controller

module) supporting 8-Gb/s data rates. Four SFP transceivers are provided in the
ship kit.

Note – The SAS host ports on the 2540-M2 FC controller tray are not for use and not

supported.

FIGURE 4-1 FC Host Ports on the Controllers—Rear View

Note – The SAS host ports on the 2540-M2 FC controller tray are not for use and not

supported.

FIGURE 4-2 SAS Host Ports on the Controllers—SAS

Caution – Risk of exposure to laser radiation—Do not disassemble or remove any

part of a Small Form-factor Pluggable (SFP) transceiver because you might be
exposed to laser radiation.

Chapter 4 Connecting Hosts 35

Connecting Host Cables to a Controller Tray

Before Connecting the Host Cables

■ Be sure that you have installed the HBAs. Refer to the documentation for the

HBAs for information about how to install the HBA and how to use the supplied
configuration utilities.

■ The type of controller host interface (SAS or FC) must match the type of the host

bus adapters (HBAs) to which you connect them.”

■ Connections for SAS use copper cables and do not require SFP transceivers.

■ See FIGURE 4-3 through FIGURE 4-5 for sample cabling patterns.

Connecting the Host Cables

1. Decide which of these steps to begin with:

■ If you have a FC interface—Go to Step 2.

■ If you have a SAS interface — Go to Step 4.

2. Be sure that the appropriate type of SFP transceiver is inserted into the host
channel.

3. If a black, plastic plug is in the SFP transceiver, remove it.

4. Perform one of these actions:

■ If you have a FC interface—Starting with the first host port of each controller,

plug one end of the cable into the SFP transceiver in the host port.

■ If you have a SAS interface—Starting with the first host port of each controller,

plug one end of the cable into the host port.

Note – The cable is either a SAS cable or a fiber-optic cable for FC connections.

FIGURE 4-3 Sample Cabling for One Host, Direct Topology

FIGURE 4-4 Sample Cabling for Two Hosts, Direct Topology

Chapter 4 Connecting Hosts 37

FIGURE 4-5 Sample Cabling for Two Hosts, FC Switch Topology

5. Plug the other end of the cable either into an HBA in the host (direct topology)
or into a FC switch topology.

Note – The SAS host interface does not support a switch topology.

6. Affix a label to each end of the cable with this information. A label is important
if you need to disconnect cables to service a controller. Include this information
on the labels:

■ Host name and the HBA port (for direct topology)

■ Switch name and the port (for FC switch topology)

■ Controller ID (for example, controller A)

■ Host channel ID (for example, host channel 1)

Example label abbreviation: Assume that a cable is connected between port 1 in
HBA 1 of a host named Engineering and host channel 1 of controller A. A label
abbreviation could be as follows.

38 Hardware Installation Guide • June 2011

Data Host Multipathing Software

Install data host software (including multipathing) on each data host that
communicates with Sun Storage 2500-M2 Arrays. The multipathing software you
need depends on the host platform, HBA, and the data transport (SAS or FC) in your
storage area network. See the Sun Storage 2500-M2 Arrays Hardware Release Notes for
the latest supported versions.

The data host multipathing software for Red Hat Linux, HP-UX, AIX, and Windows
platforms is Sun Redundant Dual Array Controller (RDAC), also known as MPP.

Multipathing is included in the Solaris 10 OS. For Solaris 9 data hosts, you need the
SAN Foundation Kit software (which includes the multipathing software).

You can download multipathing software from:

https://support.oracle.com/

For software and patch download procedures, see Sun Storage Common Array
Manager Installation and Setup Guide.

Powering On the Array

This chapter describes initial tray power-on procedures in the following sections:

■ “Before Powering On” on page 39

■ “Connecting Power Cables” on page 40

■ “Powering On the Array” on page 42

■ “Powering Off the Array” on page 43

■ “Next Steps” on page 44

Before Powering On

Decide on an IP address method before powering on.

■ The controllers will obtain IP addresses from DHCP if it is available on the

network.

■ If DHCP is not available, the controller tray defaults to internal static IP

addresses. (See the Sun Storage Common Array Manager Software Installation and
Setup Guide for information about configuring IP addresses on controller

modules.)

■ For instructions on configuring IP addresses on the controllers using the serial

interface, see “Configuring the IP Address of the Controller Modules” on page 62.

■ For an example of how to set up the DHCP server, see “Configuring a DHCP

Server” on page 69.

40 Hardware Installation Guide • June 2011

Connecting Power Cables

The controller tray and the expansion tray can have either standard power
connections to an AC power source or the optional connections to a DC power
source (–48 VDC).

Note – Do not turn on the power to the controller tray or the connected expansion

trays until this documentation instructs you to do so. For the correct procedure for
turning on the power, see “Powering On the Array” on page 42.

About AC Power Cords

■ For each AC power connector on the expansion tray, make sure that you use a

separate power source in the cabinet. Connecting to independent power sources
maintains power redundancy.

■ To ensure proper cooling and assure availability, the expansion trays always use

two power supplies.

■ You can use the power cords shipped with the expansion tray with typical outlets

used in the destination country, such as a wall receptacle or an uninterruptible
power supply (UPS). These power cords, however, are not intended for use in
most EIA-compliant cabinets.

Connecting AC Power Cords

1. Make sure that the circuit breakers in the cabinet are turned off.

2. Make sure that both of the Power switches on the expansion trays are turned
off.

3. Connect the primary power cords from the cabinet to the external power source.

4. Connect a cabinet interconnect power cord (or power cords specific to your
particular cabinet) to the AC power connector on each power module in the
expansion tray.

5. If you are installing other expansion trays in the cabinet, connect a power cord
to each power module in the expansion trays.

Chapter 5 Powering On the Array 41

About DC Power Cords

If your expansion tray has the DC power option installed, review the following
information.

FIGURE 5-1 DC Power Cable

■ Each power-fan module has two DC power connectors. Be sure to use a separate

power source for each power-fan module in the expansion tray to maintain power
redundancy. You may, optionally, connect each DC power connector on the same
power-fan module to a different source for additional redundancy.

■ A two-pole, 30-amp circuit breaker is required between the DC power source and

the expansion tray for over-current and short-circuit protection.

Connecting DC Power Cords

Caution – Risk of bodily injury—A qualified service person is required to make the

DC power connection according to NEC and CEC guidelines.

Note – Do not turn on power to the expansion tray until this guide instructs you to

do so. For the proper procedure for turning on the power, see “Powering On the

Array” on page 42.

1 Supply (negative), brown wire, –48 VDC 3 Ground, green/yellow wire

2 Return (positive), blue wire 4 DC power connector

42 Hardware Installation Guide • June 2011

1. Disconnect the two-pole, 20-amp circuit breaker for the storage array.

2. Make sure that all of the DC power switches on the DC-powered expansion
tray are turned off.

3. Connect the DC power connector cables to the DC power connectors on the rear
of the controller tray or controller tray, and expansion trays.

Note – The three source wires on the DC power connector cable (–48 VDC) connect

the expansion tray to centralized DC power plant equipment, typically through a
bus bar located above the cabinet.

Note – It is not mandatory that the second DC power connection on each of the

expansion tray’s DC power-fan modules be connected. The second DC power
connection is for additional redundancy only and can be connected to a second DC
power bus.

4. Have a qualified service person connect the other end of the DC power
connector cables to the DC power plant equipment as follows:

a. Connect the brown –48 VDC supply wire to the negative terminal.

b. Connect the blue return wire to the positive terminal.

c. Connect the green/yellow ground wire to the ground terminal.

Powering On the Array

1. Turn on both Power switches on each expansion tray that is attached to the
controller tray. Depending on your configuration, it can take several minutes
for each expansion tray to complete the power-on process.

While the power is being applied to the trays, the LEDs on the front and the rear
of the trays come on and go off intermittently

2. Check the LEDs on the expansion trays to verify that the power was
successfully applied to all of the expansion trays. Wait 30 seconds after turning
on the power to the expansion trays before turning on the power to the
controller tray.

3. Turn on both Power switches on the rear of the controller tray. Depending on
your configuration, it can take several minutes for the controller tray to
complete the power-on process.

Chapter 5 Powering On the Array 43

4. Check the LEDs on the front and the rear of the controller tray and the attached
expansion trays.

5. If you see any amber LEDs, make a note of their location.

Powering Off the Array

The array rarely needs to be powered off. You remove power only when you plan to
physically move the storage array to another location or are adding additional trays
to a controller tray.

Caution – Before turning off any power switches on a DC-powered expansion tray,

you must disconnect the two-pole, 30-amp circuit breaker.

1. Stop all I/O from the hosts, if connected, to the storage array.

2. Wait approximately two minutes until all disk drive LEDs have stopped
flashing.

Note – If Disk Scrubbing is enabled, the disk drive LEDs will continue to flash after

the 2-minute period has elapsed. By waiting the 2-minute period, you ensure that
the data residing in cache has been written to disk. The LED flash rate during disk
scrubbing (slow, periodic blink) is different from the flash rate of I/O (fast, random).

After the 2-minute period, data residing in cache is written to disk and the battery
mechanisms are disengaged.

3. Check the Cache Active LED on the controller to determine if any outstanding
cache needs to be written.

If the LED is on, there is still data that needs to be flushed and written to disk.

4. Ensure that the Cache Active LED is no longer flashing before powering off the
storage array.

5. Press each power switch at the back of the controller tray to the Off position.

6. Press the power switches at the back of each expansion tray to the Off position.

44 Hardware Installation Guide • June 2011

Next Steps

After you have connected the management host and data hosts, you are ready to
install the management host software as described in the Sun Storage Common Array

Manager Quick Start Guide or the Sun Storage Common Array Manager Installation and
Setup Guide.

APPENDIX

B

Configuring IP Addressing

To have an out-of-band Ethernet connection between the local management host and
the controller modules, the management host and the controllers must have valid IP
addresses.

This appendix describes how to configure IP addressing on the local management
host and on the controller modules. It contains the following sections:

■ “About IP Addressing” on page 61

■ “Configuring the IP Address of the Controller Modules” on page 62

About IP Addressing

Sun Storage 2500-M2 Arrays are managed out-of-band, by default, by way of a
standard Ethernet connection between the controller modules and your management
host.

Perform the following procedures to ensure that the local management host and the
controllers have valid IP addresses:

■ Configure IP addresses for the controller modules (see “Configuring the IP

Address of the Controller Modules” on page 62).

■ Configure an IP address for the management host (see the Sun Storage Common

Array Manager Software Installation and Setup Guide).

62 Hardware Installation Guide • June 2011

Configuring the IP Address of the
Controller Modules

■ Dynamic Host Configuration Protocol (DHCP) IP addressing–IP addresses for the

Ethernet port are assigned dynamically from a DHCP server running bootstrap
protocol (BOOTP) services. An IP address assigned to an Ethernet port is held
only as long as needed. By default, DHCP is enabled at initial power-on.

■ Static IP Addressing–You assign a specific IP address to the Ethernet port of each

controller. Static IP addresses remain in effect until you modify or remove them or
you change the method of IP addressing for the Ethernet port to DHCP.

■ By default, if the controllers cannot find a DHCP server upon initial power-on, an

internal IP address is assigned to Ethernet port 1 of each controller:

■ The Ethernet port of Controller A is assigned IP address 192.168.128.101

■ The Ethernet port of Controller B is assigned IP address 192.168.128.102

■ The default subnet mask for each port is 255.255.255.0

To configure the Ethernet port on a controller with either dynamic or static IP
addressing, see one of the following sections:

■ “Configuring Dynamic (DHCP) IP Addressing” on page 62

■ “Configuring Static IP Addressing” on page 63

Configuring Dynamic (DHCP) IP Addressing

If BOOTP services are available on the DHCP server at initial power on of the storage
array, this server assigns a dynamic IP address for the Ethernet port on each
controller.

If a DHCP server is not available, the controller tray defaults to internal static IP
addresses as described in “About IP Addressing” on page 61.

If you want to set up a DHCP server, refer to Appendix C for a description of how to
configure BOOTP services in Sun Solaris or Microsoft Windows environments.

You can restore DHCP IP addressing to Ethernet port 1 of either controller in either
of three ways:

■ Start a DHCP server on the same subnet, then reboot the array.

■ Using the serial port interface (see “Using the Serial Port Interface to Assign IP

Addresses” on page 63).

Appendix B Configuring IP Addressing 63

■ Using Sun Storage Common Array Manager (see the Sun Storage Common Array

Manager Installation and Setup Guide).

Configuring Static IP Addressing

There are two methods of assigning static IP addresses to the Ethernet ports of a
controller:

■ The serial port interface (see “Using the Serial Port Interface to Assign IP

Addresses” on page 63).

■ Sun Storage Common Array Manager (see the Sun Storage Common Array Manager

Installation and Setup Guide).

Using the Serial Port Interface to Assign IP Addresses

You can use the serial port interface on a controller to set the IP address for the
Ethernet port on the controller.

To use the serial port interface to configure IP addressing for the Ethernet port of
each controller, you must complete the tasks described in the following sections:

■ “Connecting a Terminal to the Serial Port” on page 63

■ “Setting Up the Terminal Emulation Program” on page 64

■ “Establishing a Connection With the Serial Port” on page 64

■ “Configuring the IP Addresses” on page 666

Connecting a Terminal to the Serial Port

You will establish a serial connection to each controller, Controller A and Controller
B. One mini-DIN to RJ45 serial port cables are supplied with each controller tray.

1. Connect the 6-pin mini-DIN connector of the serial cable to the serial port on
the controller.

2. Connect the RJ-45 connector of the serial cable to the serial port on the terminal.
It may be necessary to use the RJ45-DB9 adapter between the serial cable RJ-45
connector and the serial port of the terminal.

3. For PC and laptop serial connections, you will also need to use a null modem.
Connect the RJ45-DB9 null modem adapter between the serial cable RJ-45
connector and the PC serial port.

64 Hardware Installation Guide • June 2011

Note – If your PC does not have a serial port, you can use a USB–Serial Port adapter

(separately available from third-party vendors; not included with the ship kits).

Serial Cable Pinouts

TABLE B-1 shows the pinouts for the RJ45-mini-DIN serial cable included with the

ship kit.

Setting Up the Terminal Emulation Program

1. Select VT100 emulation.

2. Remove any modem strings from the connection profile.

3. Set up the connection profile with the following communication settings:

■ Data Rate: 38400

■ Data Bits: 8

■ Parity: None

■ Stop Bits: 1

■ Flow Control: None

Configuring a DHCP Server

This appendix describes how to configure bootstrap protocol (BOOTP) services in a
Sun Solaris and Microsoft Windows environment. It contains the following sections:

■ “Before You Begin” on page 69

■ “Setting Up a Solaris DHCP Server” on page 70

■ “Setting Up a DHCP for Windows 2000 Advanced Server” on page 73

Dynamic IP addresses are assigned through dynamic host control protocol (DHCP)
server BOOTP services.

Before You Begin

You need each controller’s media access control (MAC) address to configure the
DHCP server. The MAC address is located on the bar code label at the back of each
controller. Because there are two controller modules per controller tray, you need two
MAC addresses.

70 Hardware Installation Guide • June 2011

Setting Up a Solaris DHCP Server

The following procedure provides an example of how to set up a DHCP server with
the BOOTP option for the Solaris 8, 9, and 10 Operating Systems. Your environment
may require different steps.

1. Modify the netmasks line of the /etc/nsswitch.conf file as shown here:

#netmasks: nis [NOTFOUND=return] files

netmasks: files nis [NOTFOUND=return]

2. Start the DHCP wizard by issuing the following command at the command line:

/usr/sadm/admin/bin/dhcpmgr &

3. Select Configure as DHCP server.

4. Respond to the wizard prompts, as follows:

■ Data storage format: Text files

■ Name service to store host records: Do not manage hosts records

■ Length of lease:

■ Network Address: Network address of Controller A

■ Subnet Mask: For example, 255.255.255.0

■ Network Type: Local-Area (LAN)

■ Router: Use router discovery protocol

Appendix C Configuring a DHCP Server 71

Your summary page should look similar to the following example:

■ Starting IP address

■ Configuration macro to be used for configuring the clients

■ Lease type

72 Hardware Installation Guide • June 2011

Your summary page should look similar to the following example:

8. Verify your configuration information and click Finish.

9. In the Address Properties window, do the following:

a. In each Client ID field, enter 01 followed by the MAC address that is printed

on the back of the controller. For example:

0100A0E80F924C

b. Toward the bottom of the window, select Assign only to BOOTP clients.

c. Click OK.

The DHCP manager updates the status and client ID.

10. Go to Modify Service Options, and do the following:

a. Select Detect Duplicate IP addresses.

b. Under BOOTP Compatibility, select Automatic.

c. Select Restart Server.

d. Click OK.

Appendix C Configuring a DHCP Server 73

After the configuration process has finished, the DHCP server provides BOOTP
services to the MAC address you entered for each controller.

11. To verify that the BOOTP service is running, go to Service >> Restart.

12. After you power on the storage array, ping the address.

If the ping responds with ‘alive’, the DHCP server BOOTP operation was successful.

Setting Up a DHCP for Windows 2000
Advanced Server

Before you begin, make sure the following requirements are met:

■ Windows 2000 server and the storage array are both on the same subnet.

■ IP addresses that are assigned to the controllers do not conflict.

■ The array is in BOOTP IP addressing mode (the default setting for a new array).

■ The Windows 2000 Server setup CD is available.

The following procedure provides an example of how to set up DHCP with the
BOOTP option on the Windows 2000 Advanced Server. Your environment might
require different steps.

The New Scope wizard is displayed.

3. Enter the following information as prompted:

■ Scope name and description:

■ IP address range (for example, 192.168.0.170 to 192.168.0.171)

■ Subnet mask (for example, 255.255.255.0)

■ Add exclusions (do not exclude any IP addresses)

■ Lease duration (accept the default of 8 days)

■ Router (default gateway) of your subnet (for example, 192.168.0.1)

■ Domain name, WINS server (these are not needed)

■ Activate Scope? (select “Yes, I want to activate this scope now”)

4. Click Finish to exit the wizard.

15. Click Address Leases in the left pane to check the DHCP server leases.

The lease expiration displays the following status for each controller:

Reservation (active)

If the lease expiration for the controllers is inactive, try refreshing the list. If the lease
is still inactive, check the following:

■ Are the IP addresses allocated for BOOTP conflicting?

■ Were the correct MAC addresses added to the DHCP server for the controllers?

■ Are the DHCP server and storage array on the same subnet?

■ Is the gateway configured correctly on the DHCP server?

The controllers can gain a lease and an IP address, but they cannot respond out of
the subnet for the software if the gateway is not configured properly.

■ Are the controllers set up for BOOTP access?

It is possible that they were previously configured to have static IP addresses. You
must be sure when you move an array that you change the array’s IP addresses to
IP addresses on the new subnet before setting up BOOTP services.

System management software station.

78 Hardware Installation Guide • June 2011

controller tray One tray with drives, two controllers, fans, and power supplies. The

controller tray provides the interface between a host and a storage array.

control path The route used for communication of system management information,

usually an out-of-band connection.

customer LAN See site LAN.

DAS See direct attached storage (DAS).

data host Any host that uses the system for storage. A data host can be connected

directly to the array (direct attach storage, or DAS) or can be connected to an
external switch that supports multiple data hosts (storage area network, or
SAN). See also host.

data host software Provides tools that manage the data path I/O connections between the data

host and the storage array. This includes drivers and utilities that enable
storage management hosts to connect to, monitor, and transfer data in a
storage area network (SAN).

data path The route taken by a data packet between a data host and the storage device.

direct attached storage

(DAS)

A storage architecture in which one or two hosts that access data are
connected physically to a storage array.

disk A physical drive component that stores data.

event A notification of something that happened on a device. There are many

types of events, and each type describes a separate occurrence. See also

alarm and alert.

expansion tray A tray that does not have a RAID controller, used to expand the capacity of

an array. This type of tray must be attached to a controller tray to function.

extent A set of contiguous blocks with consecutive logical addresses on a physical

or virtual disk.

failover and recovery The process of changing the data path automatically to an alternate path.

fault coverage The percentage of faults detected against all possible faults or against all

faults of a given type.

FC See Fibre Channel (FC).

Fibre Channel (FC) A set of standards for a serial I/O bus capable of transferring data between

two ports at up to 100 megabytes/second, with standards proposals to go to
higher speeds. Fibre Channel supports point to point, arbitrated loop, and
switched topologies. Fibre Channel was completely developed through
industry cooperation, unlike SCSI, which was developed by a vendor and
submitted for standardization after the fact.

79

Fibre Channel switch A networking device that can send packets directly to a port associated with

a given network address in a Fibre Channel storage area network (SAN).
Fibre Channel switches are used to expand the number of servers that can
connect to a particular storage port. Each switch is managed by its own
management software.

field-replaceable unit

(FRU)

An assembly component that is designed to be replaced on site, without the
system having to be returned to the manufacturer for repair.

FRU See field-replaceable unit (FRU).

HBA See host bus adapter (HBA).

host As a function of the Sun Storage 2500-M2 Arrays configuration, a

representation of a data host that is mapped to initiators and volumes to
create a storage domain. See also data host, initiator.

host bus adapter (HBA) An I/O adapter that connects a host I/O bus to a computer’s memory

system. Abbreviated HBA. Host bus adapter is the preferred term in SCSI
contexts. Adapter and NIC are the preferred terms in Fibre Channel contexts.
The term NIC is used in networking contexts such as Ethernet and token
ring. See also initiator.

host group A group of hosts with common storage characteristics that can be mapped to

volumes. See also host.

hot-spare The drive used by a controller to replace a failed disk. See also array

hot-spare.

input/output module

(IOM)

A module in the expansion tray that monitors the status of the components.
An IOM also serves as the connection point to transfer data between the
expansion tray and the controller.

in-band traffic System management traffic that uses the data path between a host and a

storage device. See also out-of-band traffic.

initiator A system component that initiates an I/O operation over a Fibre Channel

(FC) or iSCSI Ethernet network. If so configured, each host connection
within the network has the ability to initiate transactions with the storage
array. Each host in the network represents a separate initiator, so if a host is
connected to the system through two host bus adapters (HBAs) or NICs, the
system identifies two different initiators (similar to multi-homed,
Ethernet-based hosts). In contrast, when multipathing is used in round-robin
mode, multiple HBAs or NICs are grouped together, and the multipathing
software identifies the group as a single initiator.

IOPS A measure of transaction speed, representing the number of input and

output transactions per second.

LAN Local area network.

80 Hardware Installation Guide • June 2011

logical unit number

(LUN)

The SCSI identifier for a volume as it is recognized by a particular host. The
same volume can be represented by a different LUN to a different host.

LUN See logical unit number (LUN).

MAC address See media access control (MAC) address.

management host A Solaris host serving the configuration, management, and monitoring

software for Sun Storage 2500-M2 Arrays. The software on the station can be
accessed with a browser to run the browser interface or with a remote
scripting command-line interface (CLI) client to access the SSCS CLI
commands.

master / alternate master A design for reliability that uses redundant configuration. Array

configurations share master/alternate master configurations: each array
configuration has two controller trays that are grouped as one host. In each
case, the master component uses the IP address and name. If the master
fails, the alternate master assumes the IP address and name and takes over
the master’s functions.

media access control

(MAC) address

The physical address identifying an Ethernet controller board. The MAC
address, also called an Ethernet address, is set at the factory and must be
mapped to the IP address of the device.

mirroring A form of storage – also called RAID Level 1, independent copy, and

real-time copy – whereby two or more independent, identical copies of data
are maintained on separate media. Typical mirroring technologies enable the
cloning of data sets to provide redundancy for a storage system.

multipathing A design for redundancy that provides at least two physical paths to a

target.

out-of-band traffic System management traffic outside of the primary data path that uses an

Ethernet network. See also in-band traffic.

PDU See power distribution unit (PDU).

pool See storage pool.

power distribution unit

(PDU)

The assembly that provides power management for the system. The
redundant design uses two PDUs in each system so that the system’s data
path continues to function if one of the PDUs fails.

profile See storage profile.

provisioning The process of allocation and assignment of storage to hosts.

RAID An acronym for Redundant Array of Independent Disks, a family of

techniques for managing multiple disks to deliver desirable cost, data
availability, and performance characteristics to host environments. Also, a
phrase adopted from the 1988 SIGMOD paper A Case for Redundant Arrays
of Inexpensive Disks.

81

remote monitoring Monitoring of the functions and performance of a hardware system from a

location other than where the hardware resides.

remote scripting CLI

client

A command-line interface (CLI) that enables you to manage the system from
a remote management host. The client communicates with the management
software through a secure out-of-band interface, HTTPS, and provides the
same control and monitoring capability as the browser interface. The client
must be installed on a host that has network access to the system.

SAN See storage area network (SAN).

site LAN The local area network at your site. When the system is connected to your

LAN, the system can be managed through a browser from any host on the
LAN.

Small Form-factor

Pluggable (SFP)

transceiver

A component that enables Fibre Channel duplex communication between
storage array devices. SFP transceivers can be inserted into host bus
adapters (HBAs), controllers, and input/output modules (IOMs). SFP
transceivers can support either copper cables (the SFP transceiver is
integrated with the cable) or fiber-optic cables (the SFP transceiver is a
separate component from the fiber-optic cable).

snapshot An copy of a volume’s data at a specific point in time.

SSCS Sun Storage Command System. The command-line interface (CLI) that can

be used to manage the array.

storage area network

(SAN)

An architecture in which the storage elements are connected to each other
and to a server that is the access point for all systems that use the SAN to
store data.

storage domain A secure container that holds a subset of the system’s total storage resources.

Multiple storage domains can be created to securely partition the system’s
total set of storage resources. This enables you to organize multiple
departments or applications into a single storage management
infrastructure.

storage pool A container that groups physical disk capacity (abstracted as virtual disks in

the browser interface) into a logical pool of available storage capacity. A
storage pool’s characteristics are defined by a storage profile. You can create
multiple storage pools to segregate storage capacity for use in various types
of applications (for example, high throughput and online
transaction-processing applications).

storage profile A defined set of storage performance characteristics such as RAID level,

segment size, dedicated hot-spare, and virtualization strategy. You can
choose a predefined profile suitable for the application that is using the
storage, or you can create a custom profile.

storage tray An enclosure containing disks. A tray with dual RAID controllers is called a

controller tray; a tray without controllers is called an expansion tray.

82 Hardware Installation Guide • June 2011

stripe size The number of blocks in a stripe. A striped array’s stripe size is the stripe

depth multiplied by the number of member extents. A parity RAID array’s
stripe size is the stripe depth multiplied by one less than the number of
member extents. See also striping.

striping Short for data striping; also known as RAID Level 0 or RAID 0. A mapping

technique in which fixed-size consecutive ranges of virtual disk data
addresses are mapped to successive array members in a cyclic pattern.
(SNIA).

target The system component that receives a SCSI I/O command. (SNIA).

thin-scripting client See remote scripting CLI client.

tray See storage tray.

virtual disk A set of disk blocks presented to an operating environment as a range of

consecutively numbered logical blocks with disk-like storage and I/O
semantics. The virtual disk is the disk array object that most closely
resembles a physical disk from the operating environment’s viewpoint.

volume A logically contiguous range of storage blocks allocated from a single pool

and presented by a disk array as a logical unit number (LUN). A volume can
span the physical devices that constitute the array, or it can be wholly
contained within a single physical disk, depending on its virtualization
strategy, size, and the internal array configuration. The array controller
makes these details transparent to applications running on the attached
server system.

volume snapshot See snapshot.

WWN World Wide Name. A unique 64-bit number assigned by a recognized

naming authority such as the Institute of Electrical and Electronics Engineers
(IEEE) that identifies a connection (device) or a set of connections to the
network. The World Wide Name (WWN) is constructed from the number
that identifies the naming authority, the number that identifies the
manufacturer, and a unique number for the specific connection.
