• Reset the configuration data in your CMOS. This is usually an option in
the PnP section of your CMOS.
• Otherwise, switch the FastTrak card to a different PCI slot.
How does the FastTrak Controller provide storage and/or data protection
with their logical disks?
The FastTrak Serial ATA RAID Controller card implements three different
RAID levels as follows:
RAID 0 (Stripe)
For capacity – The FastTrak logical disk will be as big as the smallest drive in
the logical disk times however many drives are in the logical disk. Any larger
HDDs will simply be truncated. The truncated space on the bigger drives is
unusable.
For sustained data transfers – Using FastTrak, a RAID 0 logical disk
consisting of two drives will transfer at about twice the speed of the slowest
drive in the logical disk. A RAID 0 logical disk consisting of four drives
(TX4200) will transfer at about three times the speed of the slowest drive in
the logical disk.
RAID 1 (Mirror)
For capacity – The FastTrak logical disk will be as big as the smallest drive in
the logical disk. The larger drive will simply be truncated. The truncated
space on the bigger drive is unusable.
For sustained data transfers – The FastTrak logical disk will write data at the
rate of the slowest drive in the logical disk. The FastTrak logical disk will read
data at twice the rate of the slowest drive in the logical disk.
RAID 10 (Mirror/Stripe) (TX4200 only)
For capacity – The FastTrak logical disk will be twice the size as the smallest
drive in the logical disk. Larger drive will simply be truncated. The truncated
space on the bigger drives is unusable.
For sustained data transfers – The FastTrak logical disk will read and write
data at the rate of the slowest drive in the logical disk.
Drive Issues
Can I add a drive to a FastTrak logical disk via hot-swap and dynamically
adjust the logical disk size?
Yes. The FastTrak Serial ATA RAID Controller card supports dynamically
adjustable RAID size and RAID level. RAID level changes depend on the
original RAID level and the number of drives available.
