Gigabyte GA-9ITDW Raid Configuration Guide - Page 3

1. RAID Configuration GIGABYTE server systems and motherboards that a RAID supports is comply with the following RAID solutions: ● Hardware RAID: Use dedicate hardware to control RAID array, and supposed to doing RAID 0, 1, 1+0, 5 configurations through software utility. ● Software RAID (Host RAID): Use BIOS setup and management utility complete RAID 0, 1, 1+0, Spare configurations and support Ultra 320 products. ● SATA RAID: Adaptec SATA RAID is embedded in the Intel south bridge chip, depending on the specific configure, it is support up to two SATA hard disk drives and RAID support 0, 1, JBOD configuration. 1.1 RAID Definition RAID 0, Striping supports up to two SCSI disk drives to read and write data in parallel. Even two hard disk drives reliability the same as single disk, but offers higher performance than a single disk. If one disk fails then all data in the array is lost. RAID 1, Mirroring copy from one hard disk to second hard disk such both of them contains exactly the same data, in case of failure of one disk, the system will boot through the second disk and data is still available to use therefore. RAID 1+0 is a combine with data striping and data mirroring. Take a stripe pair of disks and mirror them completely in parallel architecture. Excellent solution for RAID 10 provides fast and highly fault tolerant. 1.2 Installing hard disk drives In general, we suggest using the same model and capacity disk drives to create RAID array. 1. Install the disk drives into the drive bays of the respective GIGABYTE server or motherboard. 2. Select cables suitable for your disk drives. 3. Connect power code to hard disk on each HDD. 4. Enable or Disable SCSI termination. Note Please make sure your SCSI controller support U160 or U320 SCSI device and find suitable for your SCSI disk, cable and terminator. 3
