How can I change the resources that the FastTrak uses?
The FastTrak SX4300 and SX8300 are fully PnP. This means all the
resources that it uses are given to it by the PnP BIOS on the motherboard.
The FastTrak Controller supports IRQ sharing, but this feature only works
when ALL the concerned devices support it. If your motherboard allows you
to control the assignment of these resources, you may be able to remedy the
problem by:
• Changing the IRQ assignments to the PCI slots in the motherboard
BIOS during boot up.
• Reset the configuration data in your CMOS. This is usually an option in
the PnP section of your CMOS.
• Otherwise, switch the FastTrak Controller card to a different PCI slot.
How do the FastTrak SX Series RAID Controllers provide storage and data
protection with their arrays?
The FastTrak SX Series implements five RAID levels plus JBOD as follows:
• RAID 0 – Stripe
• RAID 1 – Mirror
• RAID 5 – Block Striping with Distributed Parity
• RAID 10 – Mirroring / Striping
• RAID 50 – Striping of Distributed Parity (SX8300 only)
• JBOD – Single disk drives
See “Introduction to RAID” on page 35 for more information.
Drive Issues
Can I add a drive to a FastTrak SX Series logical drive via hot-swap and
dynamically adjust the array size/configuration?
Yes. The FastTrak Controller supports online logical drive expansion and
migration. You must use the WebPAM software to expand or migrate an
existing logical drive.
Do the HDDs on the FastTrak SX Series have to be the same size?
The disk drives that you use with the FastTrak SX Series do not have to be
the same size. If the sizes differ, the FastTrak Controller will truncate the
large drive so the capacities match. The resulting difference in drive space is
unusable, so avoid using disk drives of significantly different capacities.
