HP Direct-Connect External SAS Storage for HP BladeSystem Solutions Depoyment Guide

MDS600 single domain, high-performance cabling
This example illustrates high-performance cabling for a single-domain configuration using single-port
SATA drives. In this configuration, note the following:
• An additional cable from each MDS600 I/O module to an adjacent port on the switch offers
additional performance: one cable provides a 4x connection; two cables provide a 8x
connection. For more information on switch ports, 4x, and 8x (high-performance cabling, see
“HP 3Gb SAS BL Switch” (page 22).
IMPORTANT:
• Both cables from an MDS600 I/O module must connect to one of the following pairs of switch
ports: 1/2, 3/4, 5/6, or 7/8.
• When using SATA drives in high performance configurations, the storage enclosure drawer
must be fully populated with SATA drives.
