SnapSAN S1000 Overview

This user guide describes how to set up and use the Overland Storage SnapSAN S1000.

The storage array, available in different configurations of iSCSI, Fibre Channel, and SAS interfaces, together with the SnapSAN S1000 installed software, provides a flexible, intelligent, storage area network (SAN) solution for virtualized server environments and the growing demand for data storage. With a SnapSAN S1000, you can store, share, protect, and manage data through a single easy-to-use web interface.

Overview

Hardware

This section provides basic information about the hardware components.

Front Panel

The front of a SnapSAN S1000 server with the bezel attached:

The Front Panel Display control panel is located in the upper left corner.

Front Panel Display

There are five buttons to control SnapSAN S1000 Front Panel Display, including: ▲ (up), ▼ (down), ENT (Enter), ESC (Escape) and MUTE.

SnapSAN S1000 User Guide Hardware

2 Up button (▲)

3 Down button (▼)

4 ENT (Enter) button

5 ESC (Escape) button

6 Mute button

7 Power LED:

Green = Power ON Off = Power OFF

8 Status LED:

Red = System failure Off = No problems

9 Access LED:

Green = Host is accessing storage array Off = No Host access attempts

Disk Drive Assemblies

IMPORTANT: For proper cooling, every slot must have either a disk drive assembly or a blank disk assembly in it.

Blank Disk Assembly Empty Slot

SnapSAN S1000 User Guide Hardware

Disk drive assemblies consist of a SnapSAN S1000 disk tray with either SAS, SATA II, or Green SATA II disk drive preinstalled in it. A blank assembly consists of a special empty tray used to ensure proper airflow within the enclosure. Eight blank assemblies are included with the server.

SAS SATA II and

Green SATA II‘

The front of each disk tray has four components:

This table provides details about the front components of a disk tray:

Rear Panel

Number Description

1 Tray removal handle.

2 Latch to release the tray and tray handle.

3 Power LED:

Green = Drive is inserted and good. Red = Drive has failed. OFF = No disk drive in the tray.

4 Access LED:

Blue blinking = The disk drive is being accessed. OFF = The disk drive is not being accessed or there is no disk drive in the tray.

CAUTION: To prevent data loss, when powering down the SnapSAN S1000, perform a normal

shutdown (see “Powering Down the SnapSAN S1000” on page 2-4) to flush any data from the cache to the physical disks, as opposed to simply turning the power OFF. All active initiators need to be logged off before shutting the server down.

SnapSAN S1000 User Guide Hardware

The individual components are all configured as removable modules and are accessible from the rear.

This table describes the rear components:

Controllers

All controllers for the SnapSAN S1000 are shipped in separate packaging. Each comes with its own Battery Backup Module (BBM).

NOTE: To facilitate support of your controllers, each BBM must be installed in the controller with

which it came packaged. All controllers and batteries must be registered with the SnapSAN S1000 in which they are installed.

By default, the SnapSAN S1000 is configured as a single controller system. To change it to a dual controller system with Master and Secondary controllers:

1. Install the optional Secondary controller.

2. Go to System Maintenance > Upgrade > Controller Mode.

3. Using the drop-down list, select Dual and click Apply.

For the dual controller setup, both controllers must be the same type (for example, 10Gb iSCSI controllers).

SnapSAN S1000 User Guide Hardware

There are four different controllers available for the SnapSAN S1000. With the exception of the host SAN ports, the connections are the same on all four modules:

Dual-PORT 4Gb Fibre Channel controller:

6 BBM status button – used to check the battery when the power is OFF.

Press the Status button to activate:

• If the LED shows Green, then the BBM still has power to keep data in the cache.

• If LED stays OFF, then the BBM power has run out and it cannot provide power for the cache anymore. It needs to be recharged or replaced.

7 LEDs (from left to right):

• BBM LED (when status button pressed): Green = BBM installed and powered. Off = No BBM installed or dead.

• Cache LED: Orange = Data on the cache waiting for flush. Off = No data on the cache.

• Master Slave (MS) LED: Green = This is the Master controller. Off = This is the Slave controller.

• Controller (CTR) Health LED: Green = Controller status normal. Red = System booting or controller is not working properly. For example, a hardware failure or software error causing a hang.

8 SAN ports (depending on model):

• 4Gb Fibre Channel ports (x2) (shown without SFP modules)

• Gigabit iSCSI ports (x4)

RAID Concepts

RAID Levels

Dual-Port 6Gb SAS controller:

1 34 5 62 7

RAID is the abbreviation of Redundant Array of Independent Disks. The basic idea of RAID is to combine multiple individual drives together to form one large logical drive or volume. The operating system detects the RAID drive as a single storage device.

There are different RAID levels with different degrees of data protection, data availability, and performance. A description of supported RAID levels follow:

Type Description Min. No. of Drives

RAID 0 Disk striping. At least one

RAID 1 Disk mirroring over two disks. At least two

RAID 3 Disk striping with parity on a dedicated disk. At least three

RAID 5 Disk striping with distributed parity. At least three

RAID 6 Disk striping with dual-distributed parity. At least four

RAID 0+1 Disk mirroring of a RAID 0 group. At least four

SnapSAN S1000 User Guide Fibre Channel Concepts

Type Description Min. No. of Drives

RAID 10 Disk striping of a RAID 1 group. At least four

RAID 30 Disk striping of a RAID 3 group. At least six

RAID 50 Disk striping of a RAID 5 group. At least six

RAID 60 Disk striping of a RAID 6 group. At least eight

JBOD Independently address a drive. At least one

Volume Relationships

The following graphic describes the relationship of RAID components. One RAID Group consists of a set of virtual disks and owns one RAID level attribute. Each RAID Group can be divided into several virtual disks. The virtual disks in one group share the same RAID level, but may have different volume capacities. All virtual disks share the Cache Volume (CV) to execute the data transaction. Logical Unit Number (LUN) is a unique identifier, in which users can access through SCSI commands.

Fibre Channel Concepts

Fibre Channel is a gigabit-speed network technology which transports SCSI commands over Fibre Channel networks. Fibre Channel was primarily concerned with simplifying the connections and increasing distances, but later designers added the goals of connecting SCSI disk storage, providing higher speeds and far greater numbers of connected devices.

The SnapSAN S1000 Fibre Channel controller only supports loop networks. It does not work with Fabric networks.

A Fibre Channel Arbitrated Loop (FC-AL) is a Fibre Channel network in which up to 126 systems and devices are connected in a loop topology, with each transmitter connecting to the receiver of the device on its logical right. The Fibre Channel Arbitrated Loop protocol used for transmission is different from Fibre Channel switched and point-to-point protocols. Multiple FC-AL loops can be connected via a fabric switch to extend the network.

SnapSAN S1000 User Guide iSCSI Concepts

iSCSI Concepts

Internet SCSI (iSCSI) is a protocol which encapsulates SCSI commands and data in TCP/IP packets for linking storage devices with servers over common IP infrastructures. iSCSI provides high performance Storage Area Networks (SAN) over standard IP networks like LAN, WAN, or the Internet.

IP SANs are true Storage Area Networks which allow several servers to attach to an infinite number of storage volumes by using iSCSI over TCP/IP networks. IP SANs can scale the storage capacity with any type and brand of storage system. In addition, it can be used by any type of network (Ethernet, Fast Ethernet, Gigabit Ethernet, and 10-Gigabit Ethernet) and any combination of operating systems (Microsoft Windows, Linux, Solaris, Mac OS X, etc.) within the SAN network. IP SANs also include mechanisms for security, data replication, multi-path, and high availability.

Storage protocols, such as iSCSI, have “two ends” in the connection. These ends are initiator and target. In iSCSI, they are called the iSCSI initiator and the iSCSI target. The iSCSI initiator requests or initiates any iSCSI communication like read or write. The iSCSI target can be the storage device itself or an appliance which controls and serves volumes or virtual volumes. It performs SCSI commands sent by the initiator or is a bridge to an attached storage device.

The initiator can be either software or hardware (HBA). Refer to the SnapSAN S1000 Compatibility Guide on the Overland Storage web site for the latest certification list. OS native initiators or other software initiators use standard TCP/IP stack and Ethernet hardware, while iSCSI HBAs use their own iSCSI and TCP/IP stacks on board. Hardware iSCSI HBAs also provide their own initiator tool. Please refer to the vendors’ HBA user guide. Microsoft, Linux, Solaris, and Mac provide software versions of iSCSI initiator drivers.

SAS Concepts

SAS, short for Serial Attached SCSI, is a point-to-point serial protocol that replaces parallel SCSI bus technology (multidrop) and uses the standard SCSI command set. It has no termination issues, supports up to 16,384 devices (using expanders), and eliminates clock skew. It consists of an Initiator that originates device service requests, a Target containing logical units that receives device service requests, and a Service Delivery Subsystem that transmits information between the Initiator and the Target.

With the availability of 3Gbps and 6Gbps SAS, performance is now on par with fibre channel design and in highly random read environments can outperform fibre channel.

SnapSAN S1000 User Guide SAS Concepts

The number of host computer connections depend on how the SnapSAN S1000 is connected:

• A single SAS controller system supports two (2) direct host connections.

• A dual SAS controller system supports four (4) direct host connections.

• With a switch placed between the SnapSAN S1000 and the host computers, either SAS

controller system can support up to 32 host connections.

Installation Overview

WARNING: It is recommended that a mechanical lifter (or at least two people) be used to raise

and align the unit to prevent injury during installation. Use care when inserting or removing a unit into or out of a rack to prevent the accidental tipping of the rack causing damage or personal injury.

AVERTISSEMENT: il est recommandé que la mécanique lifter (ou au moins deux personnes)

soit utilisé pour élever et d'unifier l'appareil pour éviter des blessures pendant l'installation. Faites attention lorsque vous insérer ou de retirer une unité d'entrée ou de sortie d'un support pour empêcher le déversement accidentel de la crémaillère causant des dommages ou des blessures.

CAUTION: Overland strongly recommends that you install the unit in a clean, air-conditioned

environment with power conditioning and an adequately rated uninterruptible power supply (UPS). The unit is intended to be grounded.

IMPORTANT: Before unpacking the unit, ensure that the area is free from conditions that cause electrostatic discharge (ESD). Discharge static electricity from your body by touching a

known grounded surface. Also, avoid touching pins, leads, or circuitry.

SnapSAN S1000 User Guide Installation Overview

Before starting, prepare the following items:

• A host with a Gigabit Ethernet NIC (recommended).

• A management computer on the same network as the SnapSAN S1000.

• Use either CAT 5e or CAT 6 (recommended) network cables for the management port

and the iSCSI data ports (10GB and 1Gb controllers only).

• A storage system configuration plan by your network administrator.

The plan should include network information for the management port and iSCSI data ports. If using static IP addresses, prepare a list of the static IP addresses, the subnet mask, and the default gateway.

• Gigabit switches (recommended) or Gigabit switches with VLAN / LACP / Trunking

(optional):

• For a 4-port Gigabit S1000, 4 or 8 available ports on a Gigabit switch.

• For a 2-port 10GbE S1000, 2 or 4 available 10Gb ports with SFP+ connections.

• For a 2-port Fibre Channel S1000, 2 or 4 available 4Gb Fibre Channel ports with

SFP connectors.

• For a 2-port SAS S1000, 2 or 4 available 6Gb SAS ports with SFP connectors (or

connect directly to hosts with SFP connectors for Direct Attach Storage (DAS) configuration).

• CHAP security information, including CHAP user name and secret (optional). See

“Overland Glossary & Acronym List” for details.

• For dual-controller systems, it is recommended that the host logon to the target twice

(both Controller 1 and Controller 2), and then the MPIO should setup automatically.

• For an iSCSI dual-controller system, install an iSNS server on the same LAN

(recommended).

Drive Slot Numbering

The drives can be installed into any slot in the enclosure. Slot numbering is reflected in Web Management Interface.

1 4 7 10

2 5 8 11

3 6 9 12

Different capacity drives can be installed; however, they should not be in the same RAID set, because capacity usage for all drives in the RAID is limited to the smallest drive capacity.

IMPORTANT: Install at least one drive in Slots 1 to 4 (shaded slots). System event logs are saved in these drives. Otherwise, event logs no longer exist after a reboot.

Installing the SnapSAN S1000

Using detailed instructions from the SnapSAN S1000 Quick Start Guide that came in the Accessory Kit, install the unit in the rack as follows:

1. Install the Battery Backup Modules in their appropriate controllers.

2. At the rear, install the Master controller in its slot (CL1).

3. If desired, install the optional Secondary Controller in its slot (CL2).

Management Interfaces

There are two primary methods to manage a SnapSAN S1000—the Web Management Interface and the Front Panel Display.

Web Management Interface

For remote management and daily usage, the SnapSAN S1000 uses a web graphic user interface called the Web Management Interface. It supports most common web browsers, including Internet Explorer 7 or 8, and Firefox 3.5. JavaScript must be enabled in the browser and a LAN cable connected to the Management port of the SnapSAN S1000.

The default IP setting is DHCP. Check the Front Panel Display to find the DHCP address displayed there. If your network doesn’t have a DHCP server, you will need to configure a static IP address using the Front Panel Display (as detailed in the SnapSAN S1000 Quick Start Guide).

Enter the unit’s IP address into your browser to access the authentication screen. With some browsers, you may need to prefix the address with “http://” (for example, “http://192.168.10.50”).

Basic Configuration

To access the Web Management Interface of the SnapSAN S1000, you must enter a user name and password. The initial defaults for Administrator login are:

User Name: admin

Password: admin

NOTE: For user level access, enter “user” as the User Name and no password. If needed, you can

add a User password by logging on as the Administrator and going to System Configuration > Login Settings.

SnapSAN S1000 User Guide Management Interfaces

When the password has been verified, the Home Page is displayed.

but not in blinking red, please enable Tools > Internet Options > Advanced > Play animations in web pages options in IE. The default value is enabled, but some applications disable it.

For detailed information on the Web Management Interface, see Chapter 4, “Web

Management Interface.”

Front Panel Display

NOTE: The Front Panel Display bottom row of buttons are only accessible with the bezel removed.

After booting up the system, the Front Panel Display on the front of the unit shows the management port IP and “SnapSAN.”

SnapSAN S1000 User Guide Management Interfaces

To access the Front Panel Display options, press the Enter (ENT) button. Use the Up (▲) and Down (▼) arrows to scroll through the functions:

• System Info – Displays the firmware version and amount of RAM.

• Alarm Mute – Mutes an alarm after an Error occurs.

• Reboot/Shutdown – Reboots or shutdowns the system.

• Quick Install – Provides steps to create a RAID Group.

• Volume Wizard – Provides steps to create a volume.

• View IP Setting – Displays current IP address, subnet mask, and gateway.

• Change IP Config – Sets IP address, subnet mask, and gateway. There are 2 options:

DHCP (Get IP address from DHCP server) or static IP.

• Enclosure Mgmt – Shows the enclosure data for disk drive temperatures, fan status,

and the power supply status.

• Reset to Default – Resets the SnapSAN S1000 to default settings.

The default resets include Administration password set to “admin,” IP address type set to “DHCP,” the DHCP default IP address set to “192.168.10.50,” subnet mask set to “255.255.255.0,” and gateway set to “192.168.10.254.”

Warning or Error events displayed on the Front Panel Display are automatically filtered by the Front Panel Display default filter. It can be changed in the Web Management Interface under System Configuration > Log and Alert Settings.
