About FastTrak100 Disk Array Adapter
FastTrak100 is a high performance Ultra ATA/EIDE RAID controller
card that features parallel data channel operation and an onboard
BIOS. The two channels on the FastTrak100 support parallel operation
that allows for overlapped I/O under multi-tasking operating systems
and sharing the workload between multiple drives.
About Adapter BIOS
The FastTrak100 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. FastTrak100 can support drives and disk arrays with
capacities exceeding 8.4 GB using Extended Interrupt13 support.
When the FastTrak100 BIOS appears during bootup, users can press
<F2> to enter the FastBuild
TM
setup to select from menu settings.
FastBuild
™
Auto Menu Setup
This setup utility is used to build and manage FastTrak100 disk arrays.
The utility is menu driven and features the <1> Auto Setup option that
uses a simple, interactive setup process. Once the array is built, all the
array members store the configuration information in the drive’s re-
served area. See Chapter 4 that provides descriptions of individual
functions.
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 FastTrak100 connectors or
cards within the system without reconfiguring or rebuilding.
