I have an Ultra tagged MultiPack, and I like it very much, because it
has just the right size, not to noisy, and it uses the regular Sun SCA
hard disk frames. I have two disks in this MultiPack, but unfortunately
it is limited to a maximum transfer rate of 40MB/s, which is really sad,
as each of those two disk can handle much more than that.

I have been looking around for some kind of SCA chassis that can handle
LVD160 or higher, but the only thing I could find are those two or three
slot high SCA backplanes that can be integrated into a PC. But my
machine only has one spare slot free, so I really seem to be out of luck
concerning this situation...

I have thought about using a generic external SCSI box and inserting one
of those SCA backplanes for PCs. But I don't really like this solution,
because these white box chassis are usually not worth the money they cost.

So any third party offering would be great, but I couldn't find one...
