We are considering upgrading a uVax in our department to a RISC machine. Unfortunately, the funding does not permit too much more than a CPU. The current configuration on the uVax has two ESDI drives (Maxtor EXT4380 and CDC Wren6) which we would like to salvage and use on the new system. Is there a way to convert these disks to SCSI? It seems there should be an upgrade to the controller board that sits on the drive itself. Is this something the drive manufacturers in fact have? I have also heard mention of a controller from Emulex that sits on the SCSI bus and makes the translations from SCSI to ESDI. How much slower is this than a board upgrade to the drive (if such a thing exists)? Any other thoughts or suggestions are certainly welcome. Thanks...Bill ******************************************************************************** * Internet: bill@soil.princeton.edu William Wichser * * UUCP: princeton!soil!bill Princeton University * * BITNET: wwichser@PUCC.BITNET Civil Engineering and Operations Research * * Phone: 609.258.4612 E114 E-Quad * * FAX: 609.258.1270 Princeton, NJ 08544 * ********************************************************************************

The EMULEX MD21 is a pretty good SCSI<>ESDI controller. You pay only for one scsi controller this way because the MD21 is one SCSI target, and can have two luns (disks) of off it.
