In this the weakest link would appear to be the SD Card. As such it seems to me that the best solution would be to have 2 or more SCSI2SD?s in the device. I?m not sure what benefit would be achieved by using a single board to present multiple devices. Unless of course you had a drive size limitation, or you?re trying to emulate something like 2GB or 4GB drives. As an example, that would be handy for VAXen with a 1GB Boot Drive limitation.
I am using SCSI2SD cards in a VAXstation 4000/90a, and in a MV3100-80 as well as
an Alpha DS10.
In the two VAXes, I use two SCSI2SD cards, configured identically with a system drive and a
user drive on class 10 16GB microSD cards. So each microSD card has both the system drive
and the user drive.
Thus I can use VMS backup from one microSD card to another so that if one microSD card fails I can
easily recover from it. So far I have not had hardware failures, but being able to recover from a
bad software installation which has been VERY helpful.
