Introduction to the FastTrak 100 RAID
The 370DDE contains a Promise Technology FastTrak100 RAID installed
onboard. Promise designed the FastTrak100 to provide a cost-effective,
high performance RAID card that adds performance and/or reliability to PC
desktops and/or servers using Ultra ATA/100, Ultra ATA/66, or EIDE
drives.
FastTrak100 supports striping (RAID 0), mirroring (RAID 1), striping/
mirroring (RAID 0+1), or spanning (JBOD) operation, respectively. With
striping, identical drives can read and write data in parallel to increase
performance. Mirroring increases read performance through load balanc-
ing and elevator sorting while creating a complete backup of your files.
Striping with mirroring offers both high read/write performance and error
tolerance. Spanning uses the full capacity of all attached drives without
requiring identical drive size, but offers no other RAID functionality.
A FastTrak100 striped array can double the sustained data transfer rate
of Ultra ATA/66 drives. FastTrak100 fully supports Ultra ATA/100
specification of up to 100 MB/sec per drive, depending on individual
drive specifications.
FastTrak100 also offers fault tolerant, data redundancy for entry-level
network file servers or simply for desktop PC users wanting to continu-
ally protect valuable data on their PC. FastTrak100 offers RAID 1
mirroring (for two drives) and RAID 0+1 mirroring and striping (for four
drives) to protect data. Should a drive that is part of a mirrored array
fail, FastTrak100 uses the mirrored drive (which contains identical data)
to assume all data handling. When a new replacement drive is later
installed, FastTrak100 rebuilds data to the new drive from the mirrored
drive to restore fault tolerance.
FastTrak100’s bootable BIOS supports individual drives larger than
8.4GB. With FAT32 and NTFS partitioning, the array can be addressed
as one large
single
volume.
