ICH9R Introduction
Important
The least number of hard drives for RAID 0, RAID 1 or Matrix mode is 2. The
least number of hard drives for RAID 10 mode is 4. And the least number of
hard drives for RAID 5 mode is 3.
All the information/ volumes/ pictures listed in your system might differ from
the illustrations in this appendix.
The ICH9R provides a hybrid solution that combines 6 independent SATAII ports for
support of up to 6 Serial ATAII (Serial ATAII RAID) drives.
Serial ATAII (SATAII) is the latest generation of the ATA interface. SATA hard drives
deliver blistering transfer speeds up to 300MB/sec. Serial ATA uses long, thin cables,
making it easier to connect your drive and improving the airflow inside your PC. The
most outstanding features are:
1. Supports 300MB/s transfers with CRC error checking.
2. Supports Hot-plug-n-play feature.
3. Data handling optimizations including tagged command queuing, elevator
seek and packet chain command.
Intel ® ICH9R offers RAID level 0 (Striping), RAID level 1 (Mirroring and Duplexing),
RAID level 5 (Block Interleaved Distributed Parity), RAID level 10 (A Stripe of Mirrors)
and Intel
® Martix Storage Technology.
RAID 0 breaks the data into blocks which are written to separate hard drives. Spreading
the hard drive I/O load across independent channels greatly improves I/O performance.
RAID 1 provides data redundancy by mirroring data between the hard drives and
provides enhanced read performance. RAID 5 Provides data striping at the byte level
and also stripe error correction information. This results in excellent performance
and good fault tolerance. Level 5 is one of the most popular implementations of RAID.
RAID 10 Not one of the original RAID levels, multiple RAID 1 mirrors are created, and
a RAID 0 stripe is created over these. Intel Matrix RAID Technology is the advanced
ability for two RAID volumes to share the combined space of two hard drives being
used in unison.
