resources during HA failure

dmercado — Fri, 05 Jun 2020 01:35:24 GMT

Hi, i would like to clarify if im correct regarding the resources during HA failure based on the scenario below:

3 nodes of simplivity

per node: total: 1 node failure HA

22 cpu 66cpu 44 cpu

288 ram 864 ram 576 ram

5.5 TB 16.5 TB 11 TB

I belive only half of the total resources should be used for the HA to work properly, but if 1 node fails, will simplivity re-divide the resources (2 nodes left) again when this occur?

VMware HA will work in the same way in a Simplivity vrs a Non Simplivity cluster.If admission control is enabled then VMware will restart VMs if the conditions are met in the admission controll policy,

The one thing to keep in mind is that VMware HA uses a concept of slot size to determine due to the OVC having alot of memory but never being capable of VMware HA failover this should be taken into account,

https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=mmr_sf-EN_US000022611 (also in the admin guide.)

Simplivity supports a single node failure per cluster in a non zoned configuration,any more then that and quorom will come into play.
