Dear Spectrum Scale User Group,
can somebody please share with me answers to the following setup /
architectural questions:
- What size is typically required for a descOnly NSD, that will only hold a
copy of a filesystem descriptor area?
- Having a 2-node "core-cluster" and a quorum node at a third site with
locally attached descOnly NSDs to that q-node.
What are the network latency / bandwidth requirements for traffic flowing
between core-cluster-nodes and the q-node?
(from my understanding the traffic contains primarily mmfsd communication -
including FS descOnly updates - but no data/metadata I/O)
Thank you in advance for answers - have a nice weekend.
Mit freundlichen Grüßen / Sincerely
