We have been tasked to start configuring a new VAX which will run vanilla 4.2. We have a fairly good idea of what we want, except for disk drives. For our environment, we will need removable drives. They need to be fairly large (i.e. larger than the RP06s we have on our 11/70). We have experience with RM05s on a VMS system from several years ago, at which time RM05 were less than really reliable. Have RM05s gotten better? Can anyone suggest alternatives? We are fairly sure that we don't want to have anything to do with HSC-50s and/or RA drives as we will be doing operating system development and don't want to worry about those *things* yet. Can anyone offer reliability experience in the CDC9766 (RM05 equiv.)? Please reply direct, and we will summarize, etc....

For years we've used CDC 9766 300MB removable drives on SI controllers here. Pretty reliable, it's just that they take up a large amound of floor space and air conditioning. While the 9766 is heart of the RM05, the MASSBUS is a stupid DEC kludge and you need another rack of electronics the size of the 9766 to interface the drive to it. -Ron
