Notes
• As shown in this illustration, server bays
1–8 will have exclusive access to one
MDS600 enclosure and server bays 9–16
will have exclusive access to the other
MDS600 enclosure.
IMPORTANT: Because it includes two HP 3Gb SAS BL Switches, this configuration is similar in
appearance to a dual-domain, high-performance configuration. However, because of the single
I/O module in each MDS600 drawer when using single-port SATA drives, it is for single-domain
use only. The additional switch is used in conjunction with the cabling scheme and zone group
strategy to obtain best possible performance in a single-domain configuration using single-port
SATA drives.
