1 Introduction

The HP 6Gb SAS BL Switch is a single-wide interconnect module for HP BladeSystem c-Class enclosures that enables a server blade with an HP Smart Array 6Gb SAS Controller to communicate with external SAS storage enclosures and tape devices. Its 6Gb SAS technology delivers high performance, with high data bandwidth up to 600 MB/s per physical link, and is fully compatible with 3G SAS, 3G SATA, and 1.5G SATA technology. Both dual-port SAS and single-port SATA disk drive interconnections are supported, offering deployment flexibility.

The HP 6Gb SAS BL Switch is a key component in HP External SAS Storage for HP BladeSystem Solutions.

• For information about devices included in the BladeSystem portfolio, including c-Class

enclosures, ProLiant server blades, Smart Array SAS controllers, and this 6Gb SAS BL Switch, see the HP BladeSystem website (http://www.hp.com/go/bladesystem).

• For information about BladeSystem solutions using this switch, see the HP BladeSystem

Deployment Guide for Solutions with 6Gb SAS BL Switches and External SAS Storage Enclosures, available on the HP Support Center website (http://www.hp.com/go/hpsc).

Features

Simplified management:

• BladeSystem c-Class enclosures and their blade devices centralize control and reduce storage

management cost.

• The HP 6G Virtual SAS Manager application, used for zoning, is embedded in the switch

firmware.

Enterprise-class performance:

• The HP 6Gb SAS BL Switch is fully supported in the HP BladeSystem c-Class enclosure

infrastructure and is compatible with any combination of HP BladeSystem c-Class server blades.

• An existing switch can be installed or replaced without having to power down the BladeSystem

enclosure.

• Configuration and management is performed through the embedded Virtual SAS Manager

(VSM) utility. The VSM is available in both a Graphical User Interface (GUI) and a Command Line Interface (CLI).

High availability when using a pair of switches in the same interconnect row of the BladeSystem c-Class enclosure:

• The inclusion of a redundant SAS BL Switch and SAS Smart Array Controller, along with dual

I/O modules in the external storage enclosures and dual-ported disk drives, ensures that the system can tolerate a component or path failure and maintain access to the storage.

• Redundant power supplies and redundant cooling fans within the BladeSystem c-Class enclosure

provide protection against enclosure malfunction.

• Redundant firmware images and configuration settings provide protection against switch or

port malfunctions.

Features 5

Supported devices

The HP 6Gb SAS BL Switch supports the following types of devices:

• “Shared SAS storage enclosures (P2000 G3 SAS MSA arrays)” (page 6)

• “Zoned SAS storage enclosures (MDS600, D6000, and D2600/D2700 drive enclosures)”

(page 6)

• “Tape devices” (page 7)

For information about cabling and configuring the switch and any attached devices, see “Connecting

cables to the switch” (page 15).

Shared SAS storage enclosures (P2000 G3 SAS MSA arrays)

When shared SAS storage enclosures are attached to the switch:

• The storage enclosure includes an embedded RAID array controller, which is used to configure

the logical storage units (LUNs). An example of a shared SAS storage enclosure is the HP P2000 G3 SAS MSA Array System.

• The BladeSystem server blade must have a RAID array controller installed, which communicates

with the RAID array controller in the storage enclosure, but it is not used for its RAID configuration capabilities.

• The SAS BL Switch and the connected SAS storage are configured using switch-port zone

groups. The entire storage enclosure connected to that switch port is visible to all c-Class enclosure blade ports (server bays) granted access to the zone group that includes that switch port.

NOTE: Unused switch ports can be included in a zone group, to help plan for future growth.

• Server bays that need access to an external storage enclosure must be assigned the appropriate

zone group.

◦ A server bay can be assigned multiple zone groups.

◦ A switch-port zone group can be assigned to more than one server bay.

◦ Unpopulated server bays can be assigned a zone group.

• Disk drives in the storage enclosure are configured into logical units (LUNs) using a

storage-enclosure based utility such as the HP Storage Management Utility (SMU). Access or restrictions to the LUNs is controlled through mappings or other presentation methods, which grant specific server bays access to specific LUNs.

Zoned SAS storage enclosures (MDS600, D6000, and D2600/D2700 drive enclosures)

When zoned SAS storage enclosures are attached to the switch:

• The storage enclosure includes I/O modules (does not include a RAID array controller).

Examples of zoned SAS storage enclosures are the HP MDS600, HP D6000, and HP D2000 (D2600/D2700).

• The BladeSystem server blade must have a RAID array controller installed, and is used for its

6 Introduction

NOTE: The HP MDS6000 is a 3G device; when connected to the 6G SAS BL Switch, all

data traffic will be reduced to 3G.

RAID configuration capabilities.

• The SAS BL Switch and the connected SAS storage are configured using drive bay zone

groups. The group of drive bays is presented to the c-Class enclosure blade port (server bay) as if it was directly connected to that server bay.

NOTE: Unpopulated drive bays in the storage enclosure can be included in a zone group,

to help plan for future growth.

• The server bay that needs access to drive bays must be assigned to the appropriate zone

group.

◦ A server bay can be assigned multiple zone groups.

◦ A drive-bay zone group can be assigned to only one server bay.

◦ Unpopulated server bays can be assigned zone groups.

• Disk drives in the storage enclosure are configured into logical units (LUNs) using host-based

configuration utilities such as HP Array Configuration Utility (ACU).

Tape devices

When tape devices are attached to the switch:

• The tape device is configured using switch port zone groups. The entire tape device connected

to that switch port is presented to all c-Class enclosure blade ports (server bays) granted access to the zone group.

NOTE: Unused switch ports can be included in a zone group, to help plan for future growth.

• Server bays that need access to tape devices must be assigned the appropriate zone group.

◦ A server bay can be assigned multiple zone groups.

◦ A switch-port zone group can be assigned to more than one server bay.

◦ Unpopulated server bays can be assigned to a zone group.

In addition to being available on the BladeSystem Technical Resources page, these documents are also available on 6Gb SAS BL Switch page of the HP Support Center website

(http://www.hp.com/go/hpsc).

Planning the configuration

For both single- and dual-domain deployments, a variety of cabling and configuration strategies are available. Consider the server blades, switches, external storage enclosures, and external backup devices in your deployment. Develop plans for cabling the external devices and choose the appropriate zoning method (switch port or drive bay) to control access to the storage.

Getting started 9

For assistance, HP strongly recommends using the HP BladeSystem Deployment Guide for Solutions with 6Gb SAS BL Switches and External SAS Storage Enclosures. The deployment guide provides guidelines, instructions, and configuration examples for solutions centered around an HP BladeSystem c-Class enclosure with server blades, SAS BL switches, SAS controller cards, and external SAS storage enclosures.

Selecting the interconnect bay

The HP 6Gb SAS BL Switch is supported for use in the following c-Class enclosure interconnect bays:

c7000

When using P721m controllers, the 6Gb SAS BL Switch cannot be installed in c7000 interconnect bays 3 and 4. (The P721m controller cannot be installed in server expansion slot 1, which maps to interconnect bays 3 and 4.)

Each interconnect bay row in an HP BladeSystem c3000 and c7000 enclosure maps to servers via the server expansion slot in which the HP Smart Array controller card is installed.

Before installing the 6Gb SAS BL Switch in the c-Class enclosure, confirm that the controller and the switch are installed in server expansion slots and enclosure interconnect bays that map to one another.

Supported interconnect bayBladeSystem c-Class enclosure model

3 and 4c3000

3, 4, 5, 6, 7, and 8

NOTE: Different controller models are required for the different types of external storage or

backup devices being connected to the switch, and these different controller models may be limited for installation in specific expansion slots which, in turn, may limit which interconnect bays that the switch can be installed in. For example, when using the P721m controller, because the P721m controller can only be installed in server expansion slot 2, switches in these environments can only be installed in c3000 interconnect bays 3 and 4 or c7000 interconnect bays 5, 6, 7, and 8.

For information about supported SAS controllers, see the HP 6Gb SAS BL Switch QuickSpecs. For information about mappings, see user documents for your BladeSystem c-Class enclosure model. The following tables list the mappings between server expansion slots and BladeSystem enclosure

interconnect bays. For information about which expansion slots are supported for use with your controller model, see the user documents for the controller.

* When using c7000 enclosures and P721m controllers, the 6Gb SAS BL Switch can be installed only in c7000 interconnect bays 5, 6, 7, and 8, because the P721m controller cannot be installed in server expansion slot 1, which maps to c7000 interconnect bays 3 and 4.

For more information about mappings, see the HP BladeSystem Deployment Guide for Solutions with 6Gb SAS BL Switches and External SAS Storage Enclosures and user documents for your BladeSystem c-Class enclosure model. For information about supported SAS controllers, see the 6Gb SAS BL Switch QuickSpecs.

Installing the switch

NOTE:

• The SAS BL Switch can be hot-installed in an operational BladeSystem c-Class enclosure.

• Make sure that the Smart Array SAS Controllers are installed in server expansion slots that

map to the selected BladeSystem c-Class enclosure interconnect bay.

• The SAS BL Switch does not have a power on/off button. Power is automatically applied or

removed when the switch is installed or removed from the BladeSystem c-Class enclosure. Alternatively, power can be applied or removed through the Onboard Administrator application.

• Connect SAS cables to external storage enclosures only after confirming that the desired

firmware version is installed on the switch.

Installing the switch 11

1. Remove the air baffle from the selected interconnect bay.

2. Prepare the switch.

3. Install the switch in the open interconnect bay.

When installed in an operational enclosure, the switch automatically powers up and performs a series of Power On Self Tests before being operational.

NOTE: Do not connect cables to the switch at this time. HP recommends connecting cables

only after confirming that the switch is operational and has the desired, supported version of firmware installed.
