Hi All,
I’d like to consolidate the VCenter server in my two different Data Center locations into just one as Active / Passive VCSA to reduce the operational maintenance cost.
Data Center 1
Vcenter server: VMware VCSA v6.5b
18 ESXi 6.0 servers - 167 VMs
normal vSwitches no dvSwitch
Data Center 2
Vcenter server: Physical Windows Server 2008 R2 & SQL Server 2008 R2 Standard Edition.
22 ESXi 5.5 servers - 200+ VMs
Would I be able to consolidate the two VCenter servers above into single Active/Passive VCSA v6.5 VM in Data Center 1 ?
My Current link speed between the data center is around 50-60 ms when ping-ing each other.
Any kind of help and suggestion would be greatly appreciated.
Thanks,
Hello!
It's not clear what do you mean by "single Active/Passive VCSA"?
Do you whant to manager all resources with one vcenter and make it high available?
Yes, that's correct.
is that possible?
Hi,
There are multiple things we need to consider in your scenario.
1. you want to have a single vCenter instance, then the site B vCenter will not be used anymore.
2. you can not convert the site B 5.5 vCenter as a Sita-A's passive vCenter. Since the inventory DB all these are different
3. The only option is to delete the Site B vCenter and add all the host to Site A vCenter
4. Before deleting Site B vCenter you have to migrate all the hosts and VMs to a standard switch.
5. Make sure you SiteB ESXi hosts are not having any NAT to reach site A network.
Hope the above points will give some thoughts.
senthilkumar does this means, I can still do the cutover with no outage or impact when I change the production VM from dvSwitch into normal vSwitch ?
Minimal downtime is expected for the VMs when you flip the port group from VDS a to standard switch. also check the feasiblity for other integrated products with vCenter like SRM, vRA, vROPs, NSX, backup etc..
senthilkumar, No, there is no other product like SRM, vRA, etc... The backup software already supports Vcenter 6.5
Agreed, if your backup software is integrated with site-B vCenter. then you have to reconfigure the backup software with site-A vCenter after the consolidation
