Here's a few questions regarding SCSI and IPI.

1) What are the advantages of each of these disk interfaces.

2) What are the disadvantages of each of these disk interfaces.

3) Is SCSI-2 really that much slower than IPI-2?

4) Are there any drives and Sun compatible controllers that take advantage of
   the extra features of SCSI-2 (ie. 16 or 32 bits wide, 10mb/s transfer)

5) Has anyone actually seen a fast IPI controller and disk work together
   on a Sun 4/490?

6) Xylogics claims that their SV6892 will give a 24 MB/second transfer rate
   when used with Seagate's ST2105 : ref. UnixWorld p136.  Are these shipping
   now?  Has anyone had this combination work on a 4/490?
