Intel RAID configurations
This ROBO-8914VG2AR supports RAID 0, RAID 1, RAID 5, RAID (1+0) and Intel®
Matrix Storage configurations for Serial ATA hard disks drives through the Intel
ICH10DO Southbridge chip.
RAID configurations
RAID 0 (Data striping) optimizes two identical hard disk drives to read and write
data in parallel, interleaved stacks. Two hard disks perform the same work as a
single drive but at a sustained data transfer rate, double that of a single disk alone,
thus improving data access and storage. Use of two new identical hard disk drives is
required for this setup.
RAID 1 (Data mirroring) copies and maintains an identical image of data from one
drive to a second drive. If one drive fails, the disk array management software
directs all applications to the surviving drive as it contains a complete copy of the
data in the other drive. This RAID configuration provides data protection and
increases fault tolerance to the entire system. Use two new drives or use an existing
drive and a new drive for this setup. The new drive must be of the same size or
larger than the existing drive.
RAID 5 stripes both data and parity information across three or more hard disk
drives. Among the advantages of RAID 5 configuration include better HDD
performance, fault tolerance, and higher storage capacity. The RAID 5 configuration
is best suited for transaction processing, relational database applications, enterprise
resource planning, and other business systems. Use a minimum of three identical
hard disk drives for this setup.
RAID 10 is data striping and data mirroring combined without parity (redundancy
data) having to be calculated and written. With the RAID 10 configuration you get
all the benefits of both RAID 0 and RAID 1 configurations. Use four new hard disk
drives or use an existing drive and three new drives for this setup.
Intel Matrix Storage Manager. The Intel® Matrix Storage technology supported by
the ICH10DO chip allows you to create a RAID 0 and a RAID 1 set using only two
identical hard disk drives. The Intel® Matrix Storage technology creates two
partitions on each hard disk drive to create a virtual RAID 0 and RAID 1 sets. This
technology also allows you to change the hard disk drive partition size without
losing any data.
