VPlex VIAS
Hi Pals
While provisioning Storage with VIAS -vplex do we require any downtime for claiming the storage from backend arrays ?
Do we have any other usage of VIAS ? , what would be the Licensing cost of this
Thanks

Saran , VIAS will not help with downtime. Understand the reason for downtime is because the WWN of the LUN changes from a backend array WWN to a VPLEX WWN from a host perspective.

Hi Saran,
More details can I believe be found here:

VPLEX VIAS Demo video:
VPLEX VIAS demo - reduces time complexity and cost! - YouTube
I can say that there's no downtime required for claiming storage from the arrays. I presume you're talking about adding new volumes and presenting them to VPLEX.
I'm not sure on the licensing question, I'd reach out to your EMC account rep.
Thanks,
Gary

Gary, not about the new volumes , we are planning to migrate data volumes from VNX to VMAX . we need a downtime to encapsulate the backend volumes to storage volumes. So i am just curious with the help of VIAS does the downtime be avoided ?

Ah I see, thanks for the clarification. As Ankur says, VIAS doesn't help here. Fortunately, if it's any consolation, the VPLEX encapsulation is process is a one-time thing (never have to perform it again! :-)

Yes , but for migration we need to take little downtime since the LUN variables would vary.

VPLEX does not modify the contents of the underlying lun. Windows hosts will see the same signature on the lun and use assign appropriate drive letters based on the registry, etc. All that the hosts sees is a new path to the same device.

Does it applies to all type of host like unix ,AiX , i had a thought that we may need to some config changes at host level after migration.

It will vary by host OS, but in general all the host see's is a path change. VPLEX does not modify the underlying physical disk as part of an encapsulation process. Some logical volume managers do 'care' about the physical path (for example older AIX and HPUX), but today most Unix's and Linux's are fine with a device path change. For specifics for your particular host OS you should consult the procedures provided by the SolVeDesktop application. It is available on support.emc.com.
