My Compaq server can has 3 68-pin Wide Ultra2/Ultra3 SCSI channels with an LVD interface, and I'm trying to find what drives I can use with this.
Whats the details on LVD - mainly what types of drives will work with my setup?
This seems to say that all Ultra2 are LVD
Do I have to get only drives listed as LVD, or can I use any Ultra2/3 SCSI drives?
Also, is there any loss of performance from going from converting a 68-pin connection to a 80-pin drive? I'm guessing not.
I've found some very cheap wide Ultra-2 & Ultra-3 Seagate 80-Pin drives that I'd like to get (why is 80-pin so much cheaper than 68-pin??!?!) . Some list LVD in their specs, but others(cheaper) I were considering list ASA2 (seems to be a Seagate-only architecture).

From www.scsita.org : SPI-2 doubles the speed again to Fast-40 commonly know as Ultra2 SCSI, 40 megatransfers per second or on a wide bus 80 megabytes per second with a new electrical interface, low voltage differential, LVD SCSI. Single ended can not be used for speeds above Fast-20. The SPI-2 standard included SIP, the Single Connector Attachment (SCA-2) 80 pin Host swap connector and the 68 pin Very High Density Connector (VHDCI). The SCSI-2 A and SPI P connectors are include in SPI-2.
