Frequently Asked Questions

What kind of disk drives can I use with VTrak?
VTrak was designed to use Serial ATA disk drives. You can also use Ultra
ATA 133/100/66 disk drives with the optional PATA-to-SATA Adapter
available from Promise Technology.
Can I take the disk drives from my UltraTrak, put them into the VTrak and
keep my logical drive (array) intact?
Yes. VTrak uses the same logical drive format as UltraTrak. Contact Promise
Technology to purchase PATA-to-SATA Adapter for your existing PATA
drives.
Can I use my existing SCSI card with VTrak?
If the SCSI card has at least a 160 MB/s data transfer rate, supports LUNs
and has a 68-pin VHDCI external connection, you can use it with VTrak.
If your SCSI card has a 68-pin HD external connector, you can purchase an
optional 68-pin HDCI to 68-pin VHDCI SCSI cable from Promise Technology.
Will I get maximum performance using my current 80 MB/s SCSI card? Do I
have to buy a 160 MB/s SCSI card?
The VTrak has a measured peak sustained throughput of 200 MB/s. Using a
80 MB/s SCSI card will result in a performance bottleneck under certain
conditions. You must estimate how frequently those conditions happen and
how serious they are. Then you can decide whether to upgrade to the faster
SCSI card.
How many VTrak subsystems can I connect to one SCSI chain?
You can connect up to eight (8) VTraks on a single SCSI chain.
Can I connect two SCSI cards to the same VTrak?
Yes. VTrak has two SCSI channels, which allows you to connect it to two
SCSI cards, whether those cards are in the same PC or two different PCs.
How can I tell when the VTrak has fully booted?
When the VTrak is fully booted up, all six front LEDs will light up green. The
right most LED will blink green once per second, while the remaining LEDs
will be solid green.
How do I learn more about configuring and using my VTrak?
Refer to the VTrak 15100 User Manual on the Software CD. That manual
contains detailed information regarding configuration, troubleshooting and
maintenance of your VTrak.
