Zoned storage—dual domain, wide-port cabling
This example illustrates cabling for an optimal high-performance, high-availability configuration
when
using dual-port SAS 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 x4 connection; two cables provide a x8
(wide-port) connection. For more information on switch ports, x4, and x8 (wide-port) cabling,
see
“HP StorageWorks 3Gb SAS BL Switch” (page 22) .
IMPORTANT: When using wide-port cabling, 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.
