Keywords: SCSI ESDI MD21 Sun-3 disk performance Message-ID: <398@sunny.ucdavis.edu> Date: 18 Jul 89 21:58:31 GMT Organization: UCDMC Clinical Engineering, Sacto., CA Lines: 16 I have run into an apparently unresolvable question. Is there a performance hit in having an ESDI disk hooked to a SCSI bus through a translator (Emulex MD21) versus a SCSI disk hanging directly on the bus? ESDI disk performance is supposed to be higher than that of SCSI disks. Does this mean that the two configurations are roughly equivalent in performance after taking into account the MD21? The questions burn on and on. Thanks. Tom. -- Tom Poage, UCDMC Clinical Engineering, Sacto., CA poage@sunny.ucdavis.edu {...,ucbvax}!ucdavis!sunny!poage
