VPLEX Meta-Volume on different arrays
Hi there,
in the best practices it says:
Best Practice states that the meta-volume must have two legs and each leg must be on a different array. If there is only one array attached to the VPLEX then you can have both legs on the same array. If there are two Dell EMC arrays it is recommended to use the Dell EMC arrays.
So if I have two VPLEX Cluster (VPLEX Metro) with one array each, will I place one meta on the local array and the mirror on the remote array that actually belongs to the other VPLEX?
In an older best practices guide it said "use local arrays", but in newer guides this isn't mentioned anymore.

Hi, haven't been on this forum for a while.
But yes, that's what would you do. I've done this for all my VPLEX installations.
Each VPLEX Cluster should see only 3 volumes from the "other" array: Meta Volume, Meta Volume Backup and Logging Volume. Make sure you make the "local" LUN the first member of the Meta Volume.

Hey, sorry to revive an old thread, but have a similar question but regarding logging volumes. Can this method of using a remote volume from other also be used as a leg for the logging volume? I think SteveK821 what you're saying is you do use it for logging as well, hence making the logging volume mirrored over "2 arrays"

Thanks Josh, is there any documentation regarding doing it this way? I see that best practice is to mirror logging volumes over 2 arrays, but since we have 1 array at each site this was not done and it is mirrored on just one array. If this is a supported configuration?

Hi,
Thanks for your question. Yes that should work for the logging volume. https://dell.to/3Ks5S1r
Let us know if you have any additional questions.

It doesn’t seem to specify, page 14 https://dell.to/3ZX7B4u there may be more information in one of the documents or procedures on solve. https://dell.to/3ZZZuEa
