Yes. Thats a typical problem. The 53C??? might be a good candidate.
AFAIK it contains a RISCy processor and is quite far programmable. Once
I got a AlphaServer with PCI DSSI cards. The DSSI was implemented with
53C525...
It would be especially interresting if the SCSI chip of the Sun ELC is
capable of implementing a target. The ELC board isn't that large, fits
in an external SCSI enclosure, can be driven with a 5 V / 2 A PSU, is a
very nice piece of hardware, boots NetBSD nicely over Ethernet and
would be able to do that iSCSI trickery. I have several ELC boards
around from machines with dead CRTs. In the days of NetBSD 1.5 or 1.6
I built a CDR copy applience out of one...
I once built a card cage (out of wood ;)) that held a row of ELC and
SLC boards. It ran a bunch of services for an ISP. That setup worked
amazingly well!
