RAID 5 (Striping with Parity):
In this RAID level, data is stripped into blocks and spread across three or more storage devices. Each block contains the
data and a parity for fault tolerance. In an event of a drive failure, the parity helps build the lost piece of data. To further
enhance the write performance, IRST uses Volume Write-Back Cache and Coalescer. The Volume Write-Back allows writes
to be buffered, and Coalescer allows multiple write requests to be combined to reduce the overhead on parity calculation.
4.
RAID 10 (Striping and Mirroring)):
RAID 10 is created, mirroring (RAID 1) the stripped (RAID 0) array. This RAID level uses four or more storage devices. It has
great reliability like a RAID 1 and performance like a RAID 0.
RAID-ready
A RAID-Ready configuration allows migration from one non-RAID SATA drive to a SATA RAID configuration.
NOTE:
A reinstall of the operating system is not required for the migration.
A RAID-Ready computer must meet the following requirements:
●
Supported Intel Chipsets
●
One Serial ATA (SATA) hard drive
●
RAID controller enabled in the computer setup
●
BIOS that includes the IRST option ROM
