Selecting The Interconnect Bay - HPE 6Gb SAS BL User Manual

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.
For assistance, Hewlett Packard Enterprise strongly recommends using the 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 BladeSystem c-Class enclosure with server blades, SAS BL switches, SAS
controller cards, and external SAS storage enclosures.

Selecting the interconnect bay

The 6Gb SAS BL Switch is supported for use in the following c-Class enclosure interconnect
bays:
BladeSystem c-Class enclosure model
c3000
c7000
1
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 HPE BladeSystem c3000 and c7000 enclosure maps to servers
via the server expansion slot in which the 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.
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 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.
