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, secondary I/O module, port 1 ◦ Port 5: to MDS600 drawer 1, secondary I/O module, port 1 Notes • If sufficient ports on the switch are available, HP recommends connecting an additional cable from the switch to the I/O modules, for additional performance.

Zoned storage—dual domain, standard cabling
This example illustrates standard cabling for a high-availability configuration when
using dual-port
SAS 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,
secondary I/O module, port 1
◦
Port 5: to MDS600 drawer 1,
secondary I/O module, port 1
Notes
•
If sufficient ports on the switch are
available, HP recommends connecting an
additional cable from the switch to the I/O
modules, for additional performance. For
an example, see
“Zoned storage—dual
domain, wide-port cabling” (page 95)
•
As shown in this illustration, server bays
1–8 may access MDS600 drawer 2 and
server bays 9–16 may access MDS600
drawer 1. For more information, see
“HP
3Gb SAS BL Switch port information”
(page 83)
