Re: Domino cluster on OS400 and Windows?

follow-up

I now have one 7.0.0 on Linux, two 6.5.4FP1 on Linux
blackberry (6.0.3) and sametime (6.5.1) in one Win2K one 6.5.4FP1 left on 
NT4
and one (corporate) on OS400 (looking to peel that off
to a Linux box ASAP)

Really??? I have never seen or even heard of a Windows machine that could
stay up for 6 to 12 months without a restart.

Re: Domino cluster on OS400 and Windows?






Actually that is a great answer for me. I only have 2 DPAR's on our
iSeries
currently so I will only need 2 Intel server Blades for our SAN (both 2
CPU). I have only ever ran Domino on the iSeries so this is going to be
something new for me. What is the restart period suggested for Windows
servers running Domino? Weekly? Daily?

Scott,
        Not a good answer here.

The hardware requirement will be driven by workload. So on iSeries the WLE
can be used to define the required hardware, No such tool exists for intel
servers.
I use this rule of thumb.  (SWAG)

1 windows server for each DPAR on iSeries  (so this may be a one to many
cluster)
If you are running current iSeries hardware (i520,i550etc) 3 Intel CPUs
for each iSeries CPU should work ok.

Example.

An i520(2-way) with 4 DPAR, (Mail1, Mail2 , Apps1 HUB1) would be clustered
to 4 intel systems

Mail1a  2 cpu

Mail2a 2 cpu

Apps2a 1 cpu

Hub1a  1 cpu

I generally just run 2 GB of ram on intel servers.

Workloads vary and Mail1&2 might drive 80% of the load in which case they
may need more CPU


NONE of this should be taken as sizing recommendations.

Re: Domino cluster on OS400 and Windows?






Thanks Walter,

That is exactly what I needed to hear, is there a technote somewhere that
will shed some light on what the hardware should be on the Windows machine
compared to our iSeries?

There are no problems running clusters between platforms.

If you are setting up for failover or load balancing make sure you have
the hardware to support the load.

Domino cluster on OS400 and Windows?






Does anyone run a Domino clustered environment on both iSeries OS400 and
Windows? Any input on this would be great. Yes I know that OS400 is by far
the best platform to run Domino on, but as a backup is it OK to have a
windows machine clustered with an iSeries machine? Problems, warning
etc.... please let me know.
