RAID High Availability Storage Hardware
The first step to setting up the Intel
®
RAID High Availability Storage solution is to install and configure
the hardware components. The following Intel
®
RAID High Availability Storage hardware checklist
outlines the baseline hardware components needed for a configuration with two controller nodes.
 Two identical Intel

RAID High Availability Storage controller assemblies
 Two sets of external or internal (CiB) SAS cabling for each Intel

controller
 One SAS drive backplane or external SAS JBOD with the following characteristics:
 Support for 6Gb/s SAS
 Dual ported backplanes or dual environmental services modules (ESMs)
 Dual expanders connected to a shared-drive backplane that supports dual-ported drives
 Support for SES
 Support for dual-ported SAS and/or NL-SAS HDD and SSD drives
 Support for SCSI-3 persistent reservation
 Multiple 6Gb/s SAS or NL-SAS drives that support SCSI-3 persistent reservation
Note: The expanders and the dual-port backplane are programmed to route SAS data such that both
Intel
®
RAID High Availability Storage controllers can discover both SAS addresses for all of the drives.
For an Intel® RAID High Availability Storage configuration, the expander must have two four-lane In
ports. The expander also requires many disk ports assigned according to the cable and backplane
