I am trying to find out everything I can about high-speed storage servers. The
requirements I am looking for are:
1. minimum 20GB disk space
2. high-speed network interface (HiPPI or Ultranet, not FDDI)
3. high-bandwidth transfer rates, on the order of 20-30 MBytes/second
4. potential for sharing between hosts, two or more, whether directly
connected or through the network; note that this implies some software
support to co-ordinate file access
5. UNIX support
6. reasonable pricing (~$3K/GB for total package even at the low end of
the potential capacity range)
I am not particularly looking for a hierarchical storage system involving
automated archiving to some sort of tape or optical medium. The main interest
is fast shareble access to large amounts of disk space.
Point 4 in particular is interesting. Other than the RPC locking daemon, is
there such a beast in existence? Has anybody written other UNIX software to
co-ordinate this? Would lockd be adequate for this sort of scenario, particu-
larly if hosts were all directly connected (multi-ported)?
I need: vendor names and telephone numbers, basic description, ballpark pricing
if you know it.
Please email to me and I will summarize to the lists.
Thank you very much.
