Minimum Requirements
•
Computer with CD-ROM Drive (not attached to the IIR controller)
•
One available PCI slot as required for your IIR controller
•
IIR controller
•
PCI 2.2 compliant system BIOS
•
SCSI hard disk drives (the minimum needed in order to meet desired RAID level
requirements)
Note:
Not all adapters are configured with removable SDRAM. If the IIR controller is
configured with removable SDRAM, be sure that the DIMM is installed in the adapter
prior to use. For installation details and applicability to your IIR controller, refer to the

Notes and Cautions
1. The number of disk drives can not be decreased (only increased via the
array
expansion
feature) once the host drive is created.
2. RAID 10 only supports an
even
total number of disk drives. Additional drives are
added in pairs, up to a total of 30 drives over 2 channels.
