vCloud Director: using different ESXi clusters and vCenters

[jadedpuppy]

Apologies for a very newb-ish question, but my knowledge of vCD is very limited.

Can vCD control and manage the following:

1.  Multiple ESXi clusters under the same vCenter?

vCD -> ESXi Cluster A and ESXi cluster B

2.  Multiple vCenter servers, with their own ESXi clusters.

vCD -> vCenter A and vCenter B.  vCenter A -> ESXi Cluster A1 and ESXi cluster A2.  vCenter B -> ESXi Cluster B1 and ESXi cluster B2.

Hopefully that all makes sense.  I'll be happy to extrapolate further.

Hi,

    Please find the answers

1.  Multiple ESXi clusters under the same vCenter?

vCD -> ESXi Cluster A and ESXi cluster B

Yes,VCD certainly support taking resources from multiple clusters.To be more specific allocation model is deciding factor whether we can span across clusters or not.

2.  Multiple vCenter servers, with their own ESXi clusters.

vCD -> vCenter A and vCenter B.  vCenter A -> ESXi Cluster A1 and ESXi cluster A2.  vCenter B -> ESXi Cluster B1 and ESXi cluster B2.

Yes,We can certainly have multiple VC linked to VCD.At max it supports 25 VC.

Thanks for the information.

I have another question about several vCenter in vCD.. so when i have several vCenters like this:

vCD -> vCenter A and vCenter B. 

vCenter A -> ESXi Cluster A1 and ESXi cluster A2. 

vCenter B -> ESXi Cluster B1 and ESXi cluster B2.

Is there an issue in vCD when i have same storage profile names on both vCenters?

example:

vCD -> vCenter A and vCenter B

vCenter A -> storage profile name: gold, silver, bronze

vCenter B -> storage profile name: gold, silver, bronze

It's a good question SS1903.

I think this will not be a problem for vCD, because you can only add storage policies to specific Provider (Provider is per Cluster or RP in Cluster). So when you create a new VM it's inherits storage profiles from his Oganization VDCs (strictly speaking from Provider) .

So I think it should work, but better options is to have unique names in several vCenters or share datastores with the same storage policies between all clusters.
