I will try my best to condense the replies into the "essence" of what
was said.
Get up to speed on TruClustering, it is more than just having the right
hardware. Shared storage is definitely the way to go probably using
fiber host bus adapters. Beware of older technology for example, the
latest patch kits have changed the Adaptec driver so it no longer works
with the old StorageWorks shelf. Go with officially supported stuff,
don't try to hack stuff together.
For this light of a load, another AS1200 and HSZ70 or 80 based system
would work, if it is still supported.
I had one person that has 2 AS1200s for sale cheap, I will give him a
call to get more information.
Original question:
Mostly hardware related question with enough Unix so I don't violate
group rules!
I have an Alphaserver 1200 running Tru64 Unix 5.1 with a small
application that has become pretty important. It has two mylex
controllers with internal drive space roughly 70 gb. Cpu usage 10-12%,
low memory utilization and hardly any swapping. 2 cpus with a gb of
memory.
We would like to increase the availability of this machine by clustering
it or getting two new machines. The one issue I see with clustering it
is that the drives are internal. I have no experience with Tru64
clustering although I have done VMS clustering for years. Any
recommendations on which (low end) machines you would use to do this or
if you have done this and would like to share, I would appreciate it.
I imagined maybe a couple DS10s and an MSA100 (mini san) with some
storage.
