P2000 G3 SAS MSA dual-controller, dual-domain, standard cabling This example illustrates standard cabling for a high-availability configuration. In this configuration, note the following: • One cable from each switch to each MSA controller offers high availability. NOTE: Restrictions exist, depending on the controller, storage enclosure, and drive model. For more information, see "External SAS device, controller, drive, and cabling support matrices" (page 77) Devices and quantities P2000 G3 SAS MSA controller enclosures: 1 P2000 drive enclosures: 0 BladeSystem c7000 enclosures: 1 6G SAS BL Switches: 2 Server blade types: half-height and full-height Connection details • Switch in interconnect bay 5: ◦ Port 1: to MSA SAS port A1 • Switch in interconnect bay 6: ◦ Port 1: to MSA SAS port B1 Notes • If additional ports on the MSA controllers or SAS BL Switch are available, HP recommends connecting an additional cable from the switch to the MSA controllers, for additional performance and fault tolerance.

P2000 G3 SAS MSA dual-controller, dual-domain, standard cabling
This example illustrates standard cabling for a high-availability configuration. In this configuration,
note the following:
•
One cable from each switch to each MSA controller offers high availability.
NOTE:
Restrictions exist, depending on the controller, storage enclosure, and drive model. For
more information, see
“External SAS device, controller, drive, and cabling support matrices”
(page 77)
Devices and quantities
P2000 G3 SAS MSA controller enclosures: 1
P2000 drive enclosures: 0
BladeSystem c7000 enclosures: 1
6G SAS BL Switches: 2
Server blade types: half-height and full-height
Connection details
•
Switch in interconnect bay 5:
◦
Port 1: to MSA SAS port A1
•
Switch in interconnect bay 6:
◦
Port 1: to MSA SAS port B1
Notes
•
If additional ports on the MSA controllers
or SAS BL Switch are available, HP
recommends connecting an additional cable
from the switch to the MSA controllers, for
additional performance and fault tolerance.
