Help...Can I run 68pin drive on 50pin interface.

[chukchee317]

Please help..

I'm wondering, can I run the 68 pin drives (UW, U2W) on a
SCSI-2 50 pin interface?

Also, anyone know where I can get a host indepedent RAID
controller for a SCSI 50 pin interface?

One more question, are all 50 pin interfaces the same?

THANKS!!!

First question - yes, however the drive will be limited to 50-pin maximum speeds (20MB/s).

Check out HyperMicro for everything SCSI, including adapters such as the one you need.

Second question - see first question. The Mylex KT950 is a good "soft" RAID controller, and the AMI MegaRAID is a bit better - onboard i960, upgradeable cache memory via ECC SIMMs, etc. HyperMicro has the MegaRAID for sure. If they don't have the Mylex, search for "KT950" at PriceWatch..

Third question - Not sure what you mean . . . 50-pin or "narrow" SCSI, I think, started off as the main internal SCSI interface, and was the main interface until the Ultra Wide interface (68-pin) came around. There are varying speeds of 50-pin SCSI, and it tops off at 20 MB/s. It will depend on your device, but most newer 50-pin devices support narrow Ultra SCSI (the 20MB/s; the previous generation was 10MB/s).
