[gpfsug-discuss] recommendations for gpfs 5.x GUI and perf/health monitoring collector nodes

[Norbert Schuld]

Hi,

when it comes to clusters of this size then 150 nodes per collector rule of
thumb is a good way to start. So 3-4 collector nodes should be OK for your
setup.
The GUI(s) can also be installed on those nodes as well.
Collector nodes mainly need a good amount of RAM as all 'current' incoming
sensor data is kept there.
Local disk is typically not stressed heavily, plain HDD or simple onboard
RAID is sufficient, plan for 20-50 GB disc space on each node.
For network no special requirements are needed, default should be whatever
is used in the cluster anyway.

Mit freundlichen Grüßen / Kind regards

We are planning to bring up the new ZIMon tools on our 450+ node cluster,
and need to purchase new
nodes to run the collector federation and GUI function on.  What would you
choose as a platform for this?
 — memory size?
 — local disk space — SSD? shared?
 — net attach — 10Gig? 25Gig? IB?
 — CPU horse power — single or dual socket?
I think I remember somebody in Cambridge UG meeting saying 150 nodes per
collector as a rule of thumb, so
we’re guessing a federation of 4 nodes would do it.  Does this include the
GUI host(s) or are those separate?
Finally, we’re still using client/server based licensing model, do these
nodes count as clients?

Thanks,
