Compatible Intel RAID Controllers
This Intel RAID Controller SRCU32 is compatible with other Intel RAID Controllers SRCU32 and
SRCMR and allows for array roaming.
✏
NOTE
Compatible refers to the ability of the Intel RAID Controller SRCU32 to read the RAID
configuration information located on hard drives that are members of RAID Arrays that have been
created on compatible adapters. Thus RAID Arrays created on compatible adapters are
interchangeable between the adapters (Array Roaming).
Optional RAID Features Implemented in the Intel RAID

Note:
1. Each Host Drive can only be associated with one RAID Array.
2. To create a new RAID Array you must initially create a Host Drive selecting the hard drives (that are available
and not already members of a RAID Array) that you wish to be members of the new RAID Array.
PCI Hot Plug
The SRCU32 adapter supports PCI Hot Plug under the following OS’s:
•
Windows 2000 Advanced Server SP2, Windows 2000 Server, Windows 2000 Professional
•
NetWare 5.1 SP2a
This IIR controller supports the PCI Hot Plug functionality for the Hot Replacement of an adapter.
Hot Replacement assumes that the drivers for the adapter being replaced are already loaded.
