[comp.unix.xenix] Compuadd ESDI and UNIX

davidsen@crdos1.crd.ge.COM (Wm E Davidsen Jr) (01/08/90)

  I asked this question several months ago and got few and contradictory
replies. Perhaps the time has come to ask again.

  Compuadd has offered a cached ESDI disk controller, priced at about
$500 with 256k cache. It purportedly provides all of the benefits of the
higher priced brands at a reasonable price. It it claimed to work with
UNIX and Xenix. However, when I asked, I found one person who helped do
QA who said it worked fine, one who couldn't get Xenix to install, and
one who got bad performance. That's too small a smaple to justify a
conclusion, so after two months I'm asking again.

  Have you used the Compuadd cached ESDI controller with UNIX or Xenix?

  Were there problems with installation?

  Does it work well in terms of reliability?

  How much cache do you have on the controller?

  How large or small is your kernel buffer pool?

  If you upgraded to Compuadd, what was the performance gain
  over your previous controller?

  Any other info to prospective buyers.

  Since I have crossposted this I am redirecting followup to me. I will
post a summary after one week and two weeks. Anyone wishing to have a
summary mailed to them should send me mail with either an internet
address or bang path starting from a mapped site (preferable uunet). I
*do not* need a full path from this machine to you, since I go through
smart mailer with maps updated every day.

  Obviously anyone who wishes can post if they feel the need to get
information out quickly.
