About FastTrak S150 SX4 and SX4000 / SX4000
Lite
FastTrak S150 SX4 and SX4000 / SX4000 Lite are high performance RAID
Controller cards that feature concurrent data channel operation and onboard
BIOS. The channels on the FastTrak card support concurrent operation that
allows for overlapped I/O under multi-tasking operating systems and sharing the
workload between multiple drives.
About Adapter BIOS
The FastTrak card contains a BIOS code that extends the standard disk service
routine provided through Int13. The BIOS is bootable for DOS and other
operating systems that rely on the system BIOS for drive operation. When the
FastTrak BIOS appears during bootup, press Ctrl-F to enter the FastBuild setup
to select from menu settings.
Reserved Sector
Array configuration data about the drive member and other members in the disk
array are saved on a special location on the disk drives called the reserved
sector. If any member of the array becomes corrupt or lost, the redundant
configuration data on the other members can be used for rebuilds.
Disk array members do not have a memory of their drive positions. This allows
drives to be placed on different FastTrak connectors or cards within the system
without reconfiguring or rebuilding.
