MDS600 and D6000 dual domain, high-performance cabling
This example illustrates cabling for an optimal high-performance, high-availability configuration
in dual domain configurations. In this configuration, note the following:
• An additional cable from each I/O module to an adjacent port on the switch offers additional
performance: one cable provides a 4x connection; two cables provide a 8x (high-performance)
connection. For more information on switch ports, 4x, and 8x (high-performance) cabling,
see “HP 6Gb SAS BL Switch” (page 20).
IMPORTANT: When using high-performance cabling, both cables from an MDS600 or D6000
I/O module must connect to one of the following pairs of switch ports: 1/2, 3/4, 5/6, or 7/8.
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”
