HP BladeSystem Deployment Guide for Solutions with 6Gb SAS BL Switches and External SAS Storage Enclosures

P2000 G3 SAS MSA with cascaded drive enclosures
This example expands on the cabling paths illustrated in “P2000 G3 SAS MSA dual-controller,
dual-domain, optimal cabling” (page 83) and shows connection paths from a dual-controller P2000
G3 SAS MSA controller enclosure to cascaded, dual I/O module P2000 drive enclosures.
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”
(page 77)
Devices and quantities

Connection details
• Switch in interconnect bay 5:
◦ Port 1: to MSA SAS port A1
◦ Port 2: to MSA SAS port B1
• Switch in interconnect bay 6:
◦ Port 1: to MSA SAS port B2

Notes
• This illustration demonstrates cascading
Large Form Factor P2000 drive enclosures.
• P2000 and D2700 drive enclosures can be
cascaded from the same P2000 G3 SAS
MSA controller enclosure.
• Up to seven drive enclosures can be
cascaded behind a P2000 G3 SAS MSA
controller enclosure, as long as the total
number of drives in the array system does
not exceed 149.
