MVPDSC sync-failover between vCMP guests in different hardware
Hello,
I'm preparing a migration and have a question about DSC support for a mixed hardware scenario:
- 2 VIPRION chassis
- each chassis has a single B2100 blade
- each blade has 3 vCMP guests
- DSC sync-failover is configured between vCMP guests hosted in those blades
- each blade will be replaced by a B2250, but the configurations won't change
I'd like to do this without downtime, but there is a crucial step, when one of the blades has already changed to a B2250 and the other is still a B2100: will vCMP guests based on different hardware be able to join in a DSC sync-failover group?
Thanks in advance!

yes that is possible, see:

Starting in BIG-IP 11.4.0, the BIG-IP system supports high availability (HA) features, such as ConfigSync and failover, between different hardware platforms.normally i would point out to size against the less powerful system. but i believe you wont run like this for long.

Hi boneyard,
Indeed the clusters won't stay asymmetric for long - maybe 1 day tops, I hope to migrate one blade one night, the other on the night after that.
Even if config-sync fails, as long as failover works properly I don't think I'll have problems.
Thanks for your help!
BR,
Mike
