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 more than 100 MB/ s per channel. 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. For more information, see page 16.
