HP 3Gb SAS Switch for HP BladeSystem c-Class - Manual (Page 23)

Zoned storage—dual domain, standard cabling
This example illustrates standard cabling for a high-availability configuration when using dual-port
SAS disk drives. In this configuration, note the following:
• One cable from each MDS600 I/O module to each switch offers high availability.
Devices and quantities
MDS600 storage enclosures: 1
MDS600 I/O modules: 4
BladeSystem c7000 enclosures: 1
3Gb SAS BL switches: 2
Server blade types: half-height and full-height
Connection details
• Switch in interconnect bay 5:
• Port 1: to MDS600 drawer 2, primary
I/O module, port 1
• Port 5: to MDS600 drawer 1, primary
I/O module, port 1
• Switch in interconnect bay 6:
• Port 1: to MDS600 drawer 2, second-
ary I/O module, port 1
• Port 5: to MDS600 drawer 1, second-
ary I/O module, port 1
Notes
• If connecting additional MDS600 storage
enclosures, use a similar cabling pattern
from available switch ports to the I/O
modules in the additional MDS600 stor-
age enclosures. For an example, see
Zoned storage—dual domain, wide-port
cabling
, page 24.
• If sufficient ports on the switch are avail-
able, HP recommends connecting an ad-
ditional cable from the switch to the I/O
modules, for additional performance and
fault tolerance.
