Appendix B Intel ICH7HD SATA RAID The optional southbridge ICH7DH provides a hybrid solution that combines four independent SATAII ports for support of up to four 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 3 Gb/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 3 Gb/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® ICH7DH offers RAID level 0 (Striping), RAID level 1 (Mirroring and Duplexing), 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 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. The minimum number of hard drives for RAID 0, RAID 1 or Matrix mode is 2. The minimum number of hard drives for RAID 10 mode is 4. All the information/volumes listed in your system might differ from the illustrations in this appendix.
