EVA Replication

Hi All,

I have EVA1 and EVA2. EVA1 has RAID5, 1 and 0. If I need to replicate EVA1 to EVA2, what do I do ? Do i need to have the same RAID5 on EVA2 ? or can i replicate RAID5 luns to RAID1 or 0. thanks,
Sajeev

Re: EVA Replication

You need licenses for Continuous Access. Then, you need the Replication Solutions Manager software used to manage replication.

You can replicate between storages using different destination VDISK Level, for example, source RAID 1 and destination RAID 5.

Re: EVA Replication

Ok, so i can use CA to replicate between different kinds of RAIDS. can I use Veritas Volume Replicator ? Are there any manuals on how to work with CA ?

thanks

Re: EVA Replication

I have Exchange databases, Oracle, on EVA1 with RAID5. I need to replicate them to EVA2 all on RAID 1 so i can shut down EVA2, move it to another location , power it on , replicate all the most recent changes over WAN from EVA1, then power off EVA1.

Re: EVA Replication

Hey Sanjeev,

If your plans are not to run the CA for long run (continously, as a DR solution) then it's not good solution to run with CA. Use any kind of mirroring software (as you mention about Veritas) to migrate the data.

Re: EVA Replication

Good question. I can't point you to a document right now, but I am fairly sure CA was also sold as a means to transfer data.

I have used it in the past to easily relocate data between EVAs.

It might not be a good idea as you have to spend quite some money for a one-time action and a host-based solution could be cheaper except if you can get CA as a loaner.

Re: EVA Replication

A quote from HP will kill you on this. Basically you need 2 times of total capacity to migrate the data. CA licenses are damn costly. Probably with 1/5th of its cost you will be able to get other software services.

No harm trying to approach HP sales for this.
