30 Intel RAID Controller SRCU32 User’s Guide
Array Roaming Compatibility
Array Roaming allows the user the ability to move a complete RAID array from one computer system
to another computer system and preserve the RAID configuration information and user data on that
RAID array. Compatible RAID controllers must control the RAID subsystems of the two computer
systems (see list of compatible controllers in this section). The transferred RAID array may be brought
online while the target server continues to run if the hard disk drives and disk enclosure support hot-
plug capabilities. The hard disk drives are not required to have the same SCSI ID in the target system
that they did in the original system that they are removed from. The RAID array drive that is being
roamed must not be of type Private. This includes all non-private host, array, and logical drives.
WARNING
The SRCU32 adapter, with firmware 2.33.xx, is not compatible with some previous versions of IIR
RAID FW running on IIR controllers. Only the versions listed below are compatible. Do not
attempt RAID Array Drive Roaming between RAID controllers that are not compatible with the
SRCU32 adapter. Unpredictable behavior may include, but is not limited to, data loss or
corruption.
Compatible adapters include:
•
SRCU31 - Firmware version 6.2.32.xx (the 6 will not show on boot)
•
SRCU31L - Firmware version 6.2.32.xx (the 6 will not show on boot)
•
SRCU32 - Firmware version 2.33.xx
•
SRCMR - Firmware version 2.32.xx

NOTE
Compatibility refers only to how data and RAID configuration information are written to the hard
disks. Compatible adapters have the same data file format.
Number of Supported Devices
The Intel RAID Controller SRCU32 supports up to 15 different SCSI devices (single hard drives,
drive enclosures, controllers, CD-ROM’s, tapes, etc). In certain configurations, this number is
reduced.
Example: Up to 14 SCSI devices if a SAF-TE processor occupies one of the SCSI ID’s.
SCSI Connectors
The Intel RAID Controller SRCU32 includes two internal SCSI-3 Ultra Wide 68-pin connectors
and two external VHDCI (Very High Density Connector Interface) 68-pin connectors. Each
connector can be fully populated with up to 15 SCSI devices (not to exceed an additive total of
15 devices per channel when using both he internal and external connector for the channel) as long
as cable length limitations for each segment are not exceeded.
