HP NetRAID-1M and 2M adapters support both basic array and spanned array configurations. • Basic arrays have logical - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 22
as one large logical drive. Each spanned array must contain the same number of disks and all the disks in the logical drive must be connected RAID Level 0 RAID 0: Striping In RAID 0 configurations, data is distributed among hard disks in the array via an algorithm called striping. Data written - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 23
Chapter 2 RAID Overview Basic Arrays with Redundancy: RAID Levels 1 and 5 RAID 1: Mirroring In RAID 1 configurations, data on one disk is completely duplicated on another disk. This is called mirroring. RAID 1 must be configured on a two-disk array. (The array cannot contain more than two disk - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 24
and data protection with a minimum loss of storage capacity. RAID 5 distributes the parity blocks equally among all disk drives. If you have five small and random. For example, to change Block 1 in the diagram above, the HP NetRAID-1M or 2M adapter must first read Blocks 2, 3, and 4 before it can - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 25
that can be attached to a single SCSI channel. For example, if the Rack Storage/12 enclosure is used, the maximum number of disks in a RAID 10 logical drive is 12. ♦ With the HP NetRAID-2M adapter, you can span up to eight RAID 1 arrays, resulting in a 16-disk RAID 10 logical drive - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 26
Spanning with Distributed Parity A RAID 50 configuration combines multiple RAID 5 arrays into a single storage space.

Each HP NetRAID-1M and 2M adapter can be configured with up to 40 logical drives - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 174

I/O is expedited because several disks It requires two physical drives in an array. • RAID 5 has parity redundancy distributed over all the disks in the array. It requires three or more physical drives in - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 175

SCSI Channel: The HP NetRAID-1M and 2M adapters control the disk drives via SCSI buses called "channels" over which the system transfers data in Fastand-Wide, Ultra SCSI - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 176
: errors on the disk have caused it to fail, or you have used an HP NetRAID utility to take the drive offline. • Rebuilding: a disk in the process SCSI ID: Each SCSI device on a SCSI bus must have a different SCSI address number (Target) from 0 to 15, but not 7, which is reserved for the SCSI - HP D5970A | HP NetRAID 1M/2M Installation & Configuration - Page 177
