Hp 6Gb Sas Bl Switch - HP 634041-006 Deployment Manual

HP 6Gb SAS BL Switch

The HP 6Gb SAS BL Switch (SAS BL switch) is HP's second-generation c-Class embedded SAS
switch designed to provide external storage for HP c-Class server blades, providing 6Gb transfer
speeds.
Key features of the HP 6Gb SAS BL Switch:
6Gb SAS links through the BladeSystem c-Class enclosure high-speed mid-plane to the server
bays
Sixteen internal SAS connections to BladeSystem c-Class server bays (2x links)
Eight external SAS ports for connections to HP external SAS storage enclosures (4x links)
High data bandwidth up to 2400MB/s per external SAS port (600 MB/s per link; 600MB/s
x 4 links =2400 MB/s per port)
8x (high performance) SAS cabling support when attached to MDS600 or D6000 storage
enclosures
Dual-domain support, when two HP 6Gb SAS BL Switches are installed in the same BladeSystem
interconnect bay row
Zoning support
Embedded HP Virtual SAS Manager software for switch management and zoning tasks
The HP 6Gb SAS BL Switch is a single-wide form factor and consumes one BladeSystem c-Class
enclosure interconnect bay. Dual-domain configurations use two HP 6Gb SAS BL Switches installed
in the same interconnect bay row.
For BladeSystem c3000 and c7000 enclosures, the SAS BL Switch can be installed in the following
interconnect bays:
BladeSystem enclosure model
c3000
c7000
1
When using P721m/P731m controllers, the 6Gb SAS BL Switch cannot be installed in c7000 interconnect bays 3 and
4. (The P721m/P731m controller cannot be installed in server expansion slot 1, which maps to interconnect bays 3 and
4.)
To achieve proper connections, the interconnect bay in which you install the switch must match up
to the expansion slot in which the controller is installed. Connections between the controller on the
server blade and the SAS switch in the BladeSystem interconnect bays are through independent
traces (mappings) on the BladeSystem c-Class enclosure midplane. For detailed information about
port mappings for the c3000 and c7000 enclosures, see the HP BladeSystem Onboard Administrator
User Guide, c3000 or c7000 user documents, and
(page 50).
As with other BladeSystem devices, the HP 6Gb SAS BL Switch can be managed through the
Onboard Administrator web interface. In addition, the Virtual SAS Manager application provides
switch-specific tasks, such as creating and assigning zone groups and updating switch firmware.
