Storage Array Configurations

The storage array design is modular, with a variety of possible configurations

FIGURE 1-2). Each configuration option includes two controllers (also referred to as a

( controlle r pair) t o provide red undanc y and fail over cap abilit ies. Eac h storag e array also has redundant Fibre Channel (FC) dat a paths and two power supplies w ith an integral battery backup system. In the event of a total power failure, each array has sufficient power from the batteries to shut down in an orderly fashion.

The system is available in three supported storage array configurations:

Chapter 1 System Overview 5

Page 24

The configuration of the system is based on requirements for throughput, amount of storage, and economy. For example, if throughput is more important to you th an economy, you might want your system to use the option 1 storage array configuration. In cont rast, if the amount of availab le storage is more important to you than throughpu t, you might w ant your syste m to use the opti on 2 or 3 storage array configuration.

A controller tray contains disk drives and built-in RAID management hardware. An expansion tray contains disk drives only and is managed by a controller tray.

FC I/O connections on the service panel connect to the controller of each array in the base cabinet. This cabling is attached at the factory before the cabinet is shipped.

For more information about array configuration, see the online help.

Internal and External Networks

The Sun StorEdge 6920 syst em incorporates three separate networks: The Storage Service Processor LAN, the internal component LAN, and the site (customer) LAN (

TABLE 1-3).

TABLE 1-3 Internal and External LANs

Network Description

Storage Service Processor LAN The Storage Service Processor LAN is used by the Sun StorEdge Remote

Response system to remotely monitor the Sun StorEdge 6920 system. When multiple Sun StorEdge 6920 systems (up to eight at the same site) are installed, the systems can share a single telephone line.

Internal Component LAN The Storage Service Processor communicates with components that make

up the system over this LAN. This network is not accessible from outside the system and is isolated from the data path.

Site (customer) LAN This LAN connects to the customer’s internal Ethernet LAN. This network

enables access to the system from the user’s management host. The management host is used to configure, control, and monitor the system through a web browser or a thin-scripting client. A firewall is included in the router of the Storage Service Processor accessory tray between the user LAN and the Storage Service Processor LAN.

Note – In addition to the firewall supplied with the Sun StorEdge 6920 system, you

can also use a site firewall implemented with your own corporate security policies. However, you cannot use your own firewall in place of the firewall supplied with the Sun StorEdge 6920 sys tem.

Software Ov erview

This section describes the following software used in the system:

■ “User Interfaces” on page 7

■ “Resident Software” on pag e 8

■ “Required Host Software” on page 8

User Interfaces

You can access the syste m software using the two ma in interfaces to the syst em:

■ A browser-based graphical user interface (GUI)

■ A command-line interface (CLI), available through a thin-scripting client for

remote mana gement

Note – See the Sun StorEdge 6920 System Release Notes for a list of supported

browsers.

In addition to providing the same control and monitoring capability as the web browser, the thin-scripting client is also scriptable. If you want to configure storage from a remote management host, you can install the thin-scripting client on an external server and then use the sscs commands to access the system.

For more information about the thin-scripting client, see the Sun StorEdge 6920 System Host In stallatio n Guide and the sscs(1M) man page.

Installing the System C abinet

This section covers the main steps for installing the base cabinet:

■ “Moving and Positioning the Base Cabinet” on page 13

■ “Stabilizing the Base Cabinet” on page 14

Required Tools

You will need the following tools for the installation:

■ Leveling wrench (shipped with the system)

■ 7/16-inch ratchet wrench

■ 1/2-inch ratche t wrench

Moving and Positioning the Base Cabinet

You must install the Sun StorEdge 6920 system in accordance with the local safety codes and regulations. This section contains additional safety information for the local facility.

1. Measure cabling distances to ensure that the supplied cable is adequate.

The grounding ca ble for the c abinet is 6.5 fe et (~2 meters) long. Refer to the product specifications in Appendix C when you are determining where

to place the cabinet.

2. Move the base cabinet into position.

Caution – A fully configured base cabinet weighs in excess of 1400 pounds (635 kg).

Ensure that all surfaces this system will move over can wi thstand this load. Additionally, the cabinet is top heavy, even when you order the minimum configuration. Keep this in mind when moving the system.

The base cabinet has wheels. Plan to have two to three people available to move the cabinet into position, one to push the system off the pallet onto the ramp, and the others to offer resistance so that the cabinet doe s not roll. Make sure there is adequate space in front of the cabinet to ensure that it will not roll into anything. Move the cabinet slowly and make sure the floor is free of objects and cables.

Chapter 2 Installing the System 13

Page 32

Caution – Never lift the system base cabinet by the cosmetic panel surfaces or pull

it from the back. Instead, push the middle section of the cabinet to prevent it from tipping over. Use two or more people to move the cabinet safely: one in front to control the movement and one behind.

3. Secure the base cabinet in position.

To minimize personnel injury in the event of a seismic occurrence, you should securely fast en th e cab inet to a rigi d stru cture ex ten ding from th e fl oor to th e ce ilin g or to the walls of the room in which you place the cabinet.

Install the cabinet on a level surface. There are adjustable nonskid pads at each corner of the cabinet base. Extend these pads when the cabinet is installed to prevent the unit from rolling. Do not use these pads to level the cabinet.

4. Ensure the base cabinet has proper ventilation.

Air cools the cabinet from front to back. Air enters at the front, circulates through the system, and is expelled at both the top and back of the cabinet. Position the cabinet so as to ensure proper ventilation.

Caution – Do not block or cover the openings of the cabinet, and do not place it

near a radiator or heat register.

Stabilizing the Base Cabinet

To stabilize the base cabinet, you must perform one of the following procedures:

■ Adjust the leveling pads and install the stabilizer legs

■ Install the floor-mounting brackets

Adjusting the Leveling Pads and Inst alling the Stabilizer Legs

Unless you are using the floor mounting brackets, the four leveling pads must be lowered to the floor for the cabinet to meet Underwriters Laboratories’ physical stability requirements.

The stabilizer legs help prevent the system from tipping over when field-replaceable units (FRUs) are serviced in the system. The stabilizer legs must be properly installed and set to be effective.

If you want to attach the system directly to the floor, skip to “Installing the FloorMounting Brackets” on page 17.

When you activate this service, the Storage Service Processor continually moni tors the messages sen t to the system log by the soft ware and firmware in the system subsystems. If a messag e contains an alert, t he system contacts the Sun Service Center.

Chapter 2 Installing the System 29

Page 48

Note – If remote monitoring via the Sun StorEdge Remote Response service is not

possible, configure RAS Telemetry for this system. The type of telemetry sent includes information such as firmware levels, WWNs, serial numbers, event logs, and system uptime. Customer data is not sent. The telemetry gathered will allow Sun to know if your system requires implementation of a field information notice (FIN), field change order (FCO), or firmware upgrade. To se t up encrypted email for RAS Telemetry, refer to the instructions in “Setting Site Information for Diagnostics and Monitoring” on page 54 to configu re the NSCC Remote Provider Service.

All of th e hardware an d softw are required to use the rem ote respo nse serv ice is included wi th the system. To set up the servic e at your site, y ou must:

■ Connect a dedicated analog telephone line with dial-out and dial-in capability.

Plug the dedicated telephone line into the PHONE jack on the service panel of the system cabine t.

■ Set up an SSRR notification provider as described in “Setting Site Information for

Diagnostics and Monitoring” on page 54.

■ Gather the information you need to activate the service using the worksheet in

Appendix A as a guide.

■ Contact your local Sun Service Center and ask for Sun StorEdge Remote Response

installation activation.

The modem installed in the system cabinet is qualified for use in most countries (see Appendix A for a list of countries) with no modification required.

If you want to connect multiple Sun StorEdge 69 20 systems to share a sing le telephone line, you must complete the installation and initial configuration of the first system. You can then connect additional Sun StorEdge 6920 sy stems, as described in “Connecting Multiple Systems” on page 77. If you want to connect the Sun StorEdge 6920 system to a Sun StorEdge 6320 system, contact the Sun Service Center.

Connecting Data Hosts

The method you use to connect data hosts depe nds on how you pl an to use the system. The Sun StorEdge 6920 system supports both storage area network (SAN) and direct attached storage (DAS) configurations for host-side server connections.

30 Sun StorEdge 6920 System Getting Started Guide • May 2004

Page 49

Redundant Fibre Channel (FC) ports located on the two I/O panels of the service panel are reserved for data host connections. A system can be configured for 16 FC or 32 FC ports. A 16-FC port configuration includes two storage resource card (SRC) sets, each consisting of two SRC processor cards and two storage I/O (SIO) cards. You can add more FC ports to the system by inst alling additional SRC sets.

With a 16-FC port configuration, use the four leftmost ports (ports 1 through 4) of the lower I/O panel to connect data hosts. The four rightmost ports (ports 5 through

8) are connected to arrays in the system. Port connections are typically evenly allocated between data hosts and arrays.

However, you can allocate additional ports for either host or array connections, depending on the needs at your site. If you need additional ports for host connections, refer to “Selecting Ports for Additional Host Connections” on page 33 for guidelines. If you need additional ports for array connections, refer to “Selecting Ports for Additional Storage Connections” on page 34 for guidelines.

Note – If you allocate more than half of the available ports for SAN or DAS hosts,

you will need an additional 1-meter LC-to-SC cable for each HBA port to physically connect the DSP to the service panel.

Troubleshooting Tips

Use this list as a guide for isolating common installation problems:

■ Verify that all power and data cables are properly installed and in the right

locations.

■ Verify that all FC connections, cable adapters, and Gigabit Interface Converters

(GBICs) are installed and secure.

■ Verify that the power to the system is turned on.

■ Check the AC power sequencer control panel:

■ If the switched outlet LEDs are not illu minated, ch eck the posi tion of the k ey

switch.

■ If one switched outlet LED is illuminated but the other is not, check the status

of the power sequencer for the unlit LED.

■ If any FRU has an amber LED, a service action is required. Go to the Storage

Automated Diagnostic Environment Event Advisor for information.

■ If some FRUs have power and others do not, check the power-on switch on the

FRUs that do not have power.

Running the Initial Configuration Script

You establish the initial configuration of the Sun StorEdge 6920 system by logging in to the system through the serial connection from a Sun workstation, a PC, or another terminal type .

This procedure describes how to establish the serial connection, log in through the service console, and run the initial configuration script. This script guides you through the configuration steps for a new system.

Establishing the Serial Connection

1. Locate the serial connection field-re placeable units (FRUs) (TABLE D-2) that came with the system.

2. Assemble the RJ45 cable with the adapter that fits either the DB9 or the DB25 serial port of a laptop, terminal, or Solaris workstation.

3. Connect the serial cable from the Service Console port on the service panel to the workstation.

4. Configure the console settings:

■

If you are using a Sun workstation, connect through the serial ports using the tip command for the appropriate port, as shown in the following example:

[3]user1: tip - 9600/dev/ttya connected

Provisioning Storage

Before you can provision storage, you must unde rstand the system’s stora ge elements and the configuration options for each. This section describes important provisioning concepts in the following topics:

■ “About Storage Elemen ts” on page 57

■ “About the Defaul t Configuratio n” on page 65

■ “Storag e Alloca tion Cons iderat ions” on page 65

■ “Provisioning Storage Using the Default Configuration” on page 66

About Storage Elements

The Sun StorEdge 6920 system consists of two types of storage elements:

■ Logical – The logical components include storage domains, volumes, storage

pools, virtual disk s, and snapshots.

■ Physical – The physical components include the storage arrays, storage trays, and

disks. (See also “Hardware Overvi ew” on page 2.)

TABLE 3-3 describes both the logical and the physical components.

Chapter 3 Configuring the System 57

Page 76

Logical Components

Storage domains

Storage domains provide secure sharing of storage resources. Storage domains allow you to organize multiple departments or applications into a single storage management infrastructure.

TABLE 3-3 Sun StorEdge 6920 Syste m Logical and Phy sical Components o f the System

Storage Domains

Volumes Volumes are created from storage pools

and presented to hosts as LUNs.

Storage pools

A storage pool is associated with a storage profile, which defines I/O performance characteristics. The system provides several storage profiles, or you can create a custom profile. A storage pool can contain zero, one, or more virtual disks.

Virtual disks A virtual disk is an abstraction of storage

created from a set of physical disks. The storage array presents the virtual disk to the system. You can have a maximum of two virtual disks per storage tray.

What Is a Storage Domain?

Storage domains are “containers” of physical and logical storage elements managed by the system. When you create a storage domain, you create a functional virtual network that is scalable and secure.

The user sees only the logical network that the storage domain creates. The storage administrator sees all the storage elements available on the system, organizes them according to need, assigns them different attributes, and creates data services that will deliver data from one end of the network to the other (from storage device to the host). Each storage domain is uniquely named and cannot be shared among different clients.

For more information about the storage domains, go to the online help system by clicking the Help button. Click the Search tab and type storage domains.

Storage Domain Provisioning Considerations

To determine how to configure your system, you have to decide how you want to use it, depending on your needs and the needs of your users. Do you want to use the default configuration as is, with only one storage domain, or divide the system into multiple smaller, but fully functioning, private, secure storage domains?

These storage domains create separate private, logical networks that can support multiple clients within one Sun StorEdge 6920 system.

The system is provisioned with one storage domain called DEFAULT. This storage domain contains the Default storage pool with its assoc iated disks and virtual disks.

Chapter 3 Configuring the System 59

Page 78

When you configure storage domains, you can do either of the following:

■ Use the existing default configuration (as is)

■ Create a custom storage domain

You can have from 1 to 64 storage domains.

What Is a Storage Profile?

A storage profile enables you to apply a predetermined set of characteristics to a storage pool at one time, instead of having to apply each characteristic individually.

Each storage profile contains storage performance characteristics such as the RAID level, segment size, dedicated hot spare, and virtualization strategy.

The default configuration uses the storage profile “Default” with the following parameters:

■ Array Segment Size: 64 Kbyt es

■ Array Read-Ahead Mode: On

■ RAID Level: RAID-5

■ Array Type: Best Match Bandwidth

■ Number of Disks: Variable

■ Dedicated Hot Spare: No

■ Virtualization Strategy: Stripe

■ Stripe Size: 1 Mbyte

Note – You ca nnot delete or modify the Default profile, and you cannot delete or

modify a profile that is in use and associated with a storage pool.

For more information about storage profiles and their characteristics, go to the online help system by clicking the Help button. Click the Search tab and type storage prof iles.

Deciding Which Storage Profile to Use

The virtualization strategy is associated with a storage profile. You can choose between two virtualization strategies:

■ Concatenation

■ Striping

60 Sun StorEdge 6920 System Getting Started Guide • May 2004

Page 79

In a concatenated volume, virtual disk partitions are filled with data sequentially, with the sec ond disk bein g written to when no sp ace remains on th e first, the third when no room remains on the second, and so on. The system di stributes the volume space across devices by using the devic es with the smalles t amount of available space first.

In a striped volume, the system divides data int o blocks and distributes (or stripes) the data blocks even ly a cross sever al disk blocks. The system dist ributes the v olume space across devices e qually by using the sm allest number of devices possible to make a volume of the desired size. Striping distributes (reads and writes) data to two or more slices that reside on different disks.

A concatenated volume does not have the enhanced performance of a striped volume. In a concat enat ed volum e the sy st em wr ite s a sing le bl ock to a si ng le virt ual disk. In a striped volume, each b lock is divided, and port ions of the data are written to different disks simultaneously. Striping data improves your disk performance because it performs simultaneous disk read/write operations on multiple disks.

You can choose any of the following options:

■ Use the default storage profile with the existing default configuration (as is)

■ Select one of the predefined storage profiles shipped with the system

■ Create a custom storage profile

For more information about virtualization strategies, go to the online help system by clicking the Help button. Click the Search tab and type concatenated or

Volumes are “containers” into which applications, databases, and file systems can put data. A volume can be a physical disk or a virtual disk mapped from one or more extents. (An extent is a set of disk blocks with logical consecutive addresses.)

The default storage configuration defines one domain with a single storage pool that uses a default p rofile. To use your stor age efficiently, you must create volumes from a storage pool that is associated with a storage profile.

For more information about volumes, go to the online help system by clicking the Help button. Click the Search tab and type volumes.

What Is a Storage Pool?

Storage pools are collections of virtual disks with the same configuration and performance characteristics. A storage pool can contain zero, one, or more virtual disks. You manage the system’ s virtual disks as a pool of storage spac e. By using

Chapter 3 Configuring the System 61

Page 80

virtual disks instead of physical disk partitions, you can reconfigure disk storage while the system is active (online). You do not need to stop storage input and output (I/O) activity, shut down the system, or back up and restore data.

Storage Pool Provisioning Co nsiderations

In the default configuration, there is one storage domain (DEFAULT) and one storage pool (Default), which uses a default storage profile. The Default storage pool contains all vi rtua l disks i n the system . If you do not wan t to use the D efault stora ge pool, you can create a new storage pool.

There are two options to choose between when configuring storage pools:

■ Use the existing default configuration (as is)

■ Create a new storage pool

For more information about storage pools, go to the online help system by clicking the Help butt on. Click th e Search tab and type storage po ols.

What Is a Virtual Disk?

A virtual disk a collection of disks or a set of contiguous disk blocks that are grouped according to RAID levels. The maximum number of virtual disks per storage tray is two.

Virtual disks are partitioned into volumes and appear to applications, databases, and file systems as physical disks. Th erefore, you can allocate storage on virtual di sks the same way you allocate storage on othe r disk devices.

Virtual Disk Provisioning Considerations

In the default configuration, all virtual disks are available to be added to either the Default storage pool or a custom-created pool.

When configuring storage pools, you can:

■ Use the existing default configuration (as is)

■ Move the default RAID-5 virtual disks to a new pool

■ Delete the RAID-5 virtual disk and create a different virtual disk in a new pool

For more information about virtual disks and RAID levels, go to the online help system by clicking the Help button. Click the Search tab and type virtual disks.

What Is a Snapshot?

The Sun StorEdge Data Snapshot software allows you to make non-disruptive pointin-time copi es of a volume’ s data. The sna pshot image can then be mou nted to another server, enabling the primary volume to continue servicing the application. Each snapshot can be accessed independently by other applications. For example, a snapshot can be mounted on a backup server, which will back up the data to tape.

A snapshot is a copy of the dat a on a volume at the moment th at you create the snapshot. This sn apshot implem entati on uses t he c opy-on-w rite, or de penden t copy, technolog y. Fo r detailed informati on about the snapshot tec hnology, see the online help.

Note – A snapshot of data is not suitable for failure recovery. You should continue

to use offline backup methods to create full-volume backup copies of your data.

The system stores snap shots i n a n area on th e pri mary vol ume call ed snapshot reserve space. The snapsh ot reserve space is configu red to take data from a primary volume (the application’s volume) and store up to eight snapshots and associated metadata.

Snapshot Plan ning Considerat ions

Before you can create a snapshot, the volume must have snapshot reserve space. You can allocate the snapshot reser ve space when you first create th e volume or w hen you first request a snapshot of the volume. In either case, the New Snapshot wizard guides you through the process.

After you allocate the snapshot reserve space, you cannot modify it, so it is important to choose th e proper size. The advantage to allocating the snaps hot reserve space a t the time you c reate the volume is that you ca n be sure there is sufficient free space for the snapshots. When you allocate the snapshot reserve space at a later time, the amount of free space you need might not be available. If you do not allocate enough snapshot reserve space, you risk running out of storage space before a snapshot can be compl eted, thereby corrupting the sn apshot data and making previous snaph ots unusable. In addi tion, if the snapshot reserve space you created is too small, you must delete existing snapshots as required to make space for new ones.

The proper size of the snapshot reserve space depe nds on the following factors:

■ The number of snapshots to be taken

The more snapshots you take, t he m ore space i s required for t he sn apshot reserve space. Specify the size of the snapshot reserve space as a percentage of the primary volume. Depending on the number of snapshots you want, specify from 1% to 800% of the primary volume’s si ze.

Chapter 3 Configuring the System 63

Page 82

■ The degree of write activity anticipated on the primary volume

Write activ ity is the num ber of writ e operatio ns that occ ur on the prim ary volume. It se rves as a measure of the net chang e in that prima ry volume over time. To determine the total space required for snapshot reserve space, specify the percentage of anticipated c hange to the primary volum e (10% to 100%) between snapshots.

■ The length of time you expect to keep a snapshot

After you take a snapshot, subsequent changes to the primary volume’s data are saved in the snapsh ot reserve space. The longer a sn apshot remains in existen ce, the larger the amount of snapshot reserve space is required.

■ The degree of write activity anticipated on the snapshot

The snapshot can be treated like a volume so you can mount it on a server and make it available to another application. Some applications change data or set a counter bit so that the snapshot itself is modified, making it different from the data that is on the primary volume. These modifications are also stored in the snapshot reserve space as well.

Snapshot space is consumed when a block is written to the primary volume that hadn't been written to since the snapshot was created, and when a block is written to the snapshot volume for the first time.

When you run the New Snap shot w izard, it is recomme nde d that yo u spec ify a writ e activity level of 100%. Once a snapshot volume has been filled up, subsequent reads and writes to the snapshot volume are rejected, so the snapshot no longer reflects changes to the primary volume. Therefore, if you do not specify a high enough level of write activity, your snapshots become invalid. Specifying a write activity level of 100% should allow for every block in the primary volume to chang e and for each of those changes to be written to the snapshot volume.

As mentioned, t he amount of space the system allocates for snapshot rese rve space is a function of the number of snapshots you anticipate taking, as well as of the write activity level you specify. Suppose you have a 100 Gbyte primary volume. If in the New Snapshot wizard you specify a snapshot number of 1 and a write activity level of 100%, the system will allocate 107 Gbytes as snapshot reserve space; in contrast, if you specify a snapshot number of 8 and a write activity level of 100%, the system will allocate 856 Gbyte s of snapshot reserve space.

About the Def ault Configuration

The system ships from the factory with a default configuration, consisting of:

■ Storage domain “DEFAULT” – All storage elements are in one storage dom ain

(DEFAULT), which can be accessed by all hosts (initiators).

■ Storage pool “Default”– All virtual disks can be added to this st orage pool.

■ Storage profile “D efa ult ” – Th e DE FAULT storage doma in us es the D e fau lt pro fi le

to specify its storage param eters. There are also several additiona l profiles provided with the system from which you can choose.

■ Virtual disks – Depending on the number of drives available, the system is

preconfigured as one RAID-5 virtual disk (7 drives) or two RAID-5 virtual disks (14 drives).

Note – The default configuration does not include volumes. To use the default

configuration “as is,” you must configure volumes. For more information, see “Storage Allocation Consider ations” on pag e 65 and “Creating Volumes” on page 67.

Storage Allocation Considerations

As you review your provisioning options and determine how to allocate storage appropriately for your site, consider the following:

■ Your site’s security requirements – By creating multiple storage domains, you

segregate i nitiato rs. For exa mple, yo u can have ho sts that handle fi nancial da ta store their data in a different domain tha n hosts that hand le research data.

■ Your site’s I/O requirements – The default configuration uses the Default storage

profile, with balanced access to storage. Depending on your needs, you can optimize I/O activity by selecting a storage profile with different characteristics or by creating a custom profile.

■ Your site’s performance requirements – In general, the number of host ports is

equal to the number of storage ports. You can add more hosts, but performance declines if you don’t also add also add ports. You can expand the number of ports by adding storage resource card (SRC) sets, up to a maximum of four.

Provisioning Storage Using the Default Configuration

This section describes the procedures for provisioning the system using the default configuration. The fi rst step, “Creating Volumes” on page 67, must be done before you can complete the provisioning process.

If you decide to con figure the system us ing the defaul t configuratio n, you must create volumes within a storage pool and then assign each initiator in your environment to one of the volumes. The system provides two wizards to assist you, the New Volume wiza rd and the Vo lume-Initi ators Mappi ng wizard.

The wizards guide you throug h the steps to create and ma p a new volume:

■ Selecting a storage pool from which to create the volume

■ Specifying th e name and des cription o f the new volu me

■ Selecting a storage pool

■ Reserving space for a snap shot

■ Determining the capacity of the volume

■ Mapping initiators to the volume
