Multiple reservations on a single compute resource

[draymond10]

I have multiple tenants (A and B)

with multiple BGs inside each tenant (A_BG1, A_BG2, B_BG1,B_BG2)

I have a compute resource FG_ABC

If I need to provision workloads from both BGs (A_BG1 and B_BG1), I'll need 2 reservations; If I need all 4 BGs to provision workloads I'll need 4 reservations.

**Check my math here** Just want to make sure.

Reservations work off exact numbers (GB/memory, GB/storage,etc).

1.  How do you calculate these resource reservations?  Do you just say A_BG1 gets 75% (which calculates to ~75GB) and B_BG1 gets 25% (which calculates ~25GB).

2.  If you add 100GB to the FG (say we add a host to a cluster), do you have to manually reconfigure those reservations to include this extra 100GB?

Just looking for feedback on how I should be reserving resources.  Thanks.

Yes that is correct. 1 reservation per business group.

All the the resources for a reservation are static numbers so if you add a host or storage you have to manually update the reservations. By going to the compute resources page you can see the total resources reserved on that compute resource. Of course, this will only show the reservations in that tenant. You can overcommit resources as well and set your alerts accordingly so that you won't run out but will still provide your business groups with adequate resources.
