1.2 Features Features of the Intel RAID Controller SRCZRCX include: • Support for hard disk drives with capacities greater than 8 Gbytes • Online RAID level migration • RAID remapping • No reboot necessary after expansion (for NT 4.0: if virtual sizing is enabled) • More than 200 Qtags per array • User-specified rebuild rate • Cache memory of 128 Mbyte. • Support for a MROMB-enabled PCI-X host interface • Support for RAID levels 0 (striping), 1 (mirroring), 5 (striping and parity data across all drives), 10 (mirroring and striping), and 50 (RAID 5 and striping) • Advanced array configuration and management utilities • Up to 40 logical drives allowed per controller • 32 Kbyte NVRAM for storing RAID system configuration information; the firmware is stored in flash ROM for easy upgrade • Battery backup for the onboard cache SDRAM when a daughter card with a battery is used (optional accessory). 1.3 Hardware You can install the SRCZRCX controller in a Modular RAID on Motherboard (MROMB)enabled PCI-X expansion slot in a server board that has either the LSI Logic* 53C1020 or 53C1030 SCSI chip on it. Note: This RAID controller is not supported by all server boards. Please refer to the tested hardware and operating system list to make sure this RAID controller can be used with your server board. The tested hardware and operating list is available at http://support.intel.com/support/motherboards/server/.

Hardware
You can install the SRCZRCX controller in a Modular RAID on Motherboard (MROMB)-
enabled PCI-X expansion slot in a server board that has either the LSI Logic* 53C1020 or
53C1030 SCSI chip on it.
Note:
This RAID controller is not supported by all server boards. Please refer to the
tested hardware and operating system list to make sure this RAID controller can
be used with your server board. The tested hardware and operating list is
