Hi guys,
in this cluster i'm hosting veru big VM with reservation on VM level.
I have 4 x host with 256 GB RAM each.
HA cluster settings "cluster tolerates 1 host failure" and i have few slot with the following :
4 slot in the cluster
4 used slot
0 available slot
0 failover slots
host size :
256mhz
10vCPU
132119MB
i'm a little bit confused about such "zeroes" especially the failover slot......
Does it mean cluster can still tolerate 1 host failure or not ?
Time ago i got an good explanation from the communities , see below.....
But my question is also is used slot - available slot =>always the sum of the value indicated in failover slot ?
Example:-
Total Number of slots = 22
Used Slots = 4 (Depends on Numbers of VM Running)
Available Slots = 7
Failover Slots = 11 ( Depends on How many hosts failure cluster can tolerate) if it is 1 and we have 2 node cluster then it is 50% of the total slots. Means you can use it according to this example you can only power on 11 VM's now not more than that.
Many thanks in advance.
