Yes, they use the EISA bus for peripherals. The adapter allows 3rd-party
SCSI disks to be cheaply interfaced to EISA.

EISA peripheral buses will max out at about 33MBytes/second, which is
well beyond today's SCSI capabilities, and far beyond a PC clone,
high end or otherwise. HP has previously announced that their whole
workstation line will migrate toward the EISA bus for peripherals. Their
previous peripheral bus was HP-IB, which was on the order of using two
tin cans and a string (just a little joke there, HP.)
