XtremIO Migration

You can also use SAN Copy to push the data from VNX to XtremIO.

Here is a good starting point on all things SANCopy:

Thanks Avi,

Is there any documentation/process which gives more information on how to use Migration (Push option) from a VNX to XtremIO?

bump!

Looking forward to people sharing their experiences .

I've had my customers migrate from Vmax to ExtremIO  . They storage Vmotioned to the ExtremIO .

Thanks all for the inputs .

We decided to use PPME 5.7 sp2 utility to do host based migration. Source LUN's are from VNX and target XtremIO .

Its a Windows 2008 standalone server that we are going to perform a migration.

Below are some highlevel steps planned for migration are there any other things/parameters/steps (need to be taken) that i need to be aware during the Migration process?

1. Assigning new storage to the server.
2. Setting up the PowerPath Migration Enabler Host Copy sessions
3. Starting and monitoring the sessions.
4. Once the initial sync completes: switch over to your target storage.
5. Finalize and clean-up.

VMAX customers can also use Open Replicator to push data to XtremIO (for migration).

That should do it....there used to be a PPME Windows guide but I don't think it has been updated so you can just follow the PPME user guide...but your steps above should be it at a high-level. You can throttle the host-copy sessions if needed during the sync.

Thank you all for the feedback.

Regarding zoning of the server to XIO, there are two HBA's on the server where one HBA going to A fabric and other HBA going to B fabric. And on the XIO ( 6 X -Brick) there are 12 XIO ports going to A fabric and 12 XIO ports going to B fabric. So when i did the zoning each device allocated to the server will be seeing 24 paths (One HBA zoned to 12 XIO ports on each fabric A and B)  . Can someone please let me know if this is as per standards/Normal? or do i need to modify any zoning. Server is a Windows 2008.

Hi Dynamox,

I was under the impression that to get better performance we need to zone the host to all the X-brick Ports. As i said we have 6 X brick cluster so i zoned the host to the 6 X-Bricks ports. If this is not a best practice for how many X bricks i should be zoning the server?

Check the XtremIO documentation on the Support website. It goes into these details and discusses various scenarios.

why would you zone so many paths ? There is a maximum number of initiators per cluster (512), you will burn through that number pretty fast if you start zoning so many paths.

Migration has been kicked and seems to be running fine. I have a question regarding the OS Boot LUN. On the windows 2008 server there is a OS LUN which is booting from SAN (VNX) and can i use same PPME tool to migrate the OS boot LUN to XIO volumes? or Are there any other methods i need to use to Migrate a OS boot LUN? Please suggest.

I believe PPME doesn't support boot lun migrations.

You can use SAN Copy

SANCopy (which is a block based tool), not online of course.
