Recommend a Good SAN

Hi Experts,

I have a project to buy a good SAN. We currently has MD3000i / MD1000 on 2 Sites. We cant replicate these 2 SANs for DR.

Can you recommend me a business class SAN which has built-in replication feature.

We run ESXi 4.1 and we don't want to use any software (Veeam, vRanger) to do the replication be cause it takes a snapshot and replicates and deletes the snapshot. During a snapshot deletion the VM IO stops for 10mins and this takes our site and servers down.

So I decided to get a SAN to SAN replication but the MD3000i does not have this feature.

My Budget is around £15k. Please recommend me a good SAN.

IBM Storwize v7000 can replicate whole volumes to another storage subsystem as long as it's connected via Fiber or iSCSI.  I have a v7000 and I've specifically used this functionality before.

Netapp also do a V-Series which can take storage, and replicate between storage subsystems.

Take a look at a EMC VNXe series, they're a little bit cheaper than the Netapp but offer more features than the MD1000/3000 series (which is now owned by Netapp since it was an LSI rebrand prduct which Netapp bought out)

HP P2000 G3 MSA FC/iSCSI combo would also do (but not the other possible controllers you can get in that range).

Dell EqualLogic is a very good enterprise level SAN with replication built in. I am not sure if you can buy two units with enough IOPS and capacity with your budget, however. Speak with Dell or a channel partner.

Another option could be different replication software. Look at Double-Take for your replication. It isn't based on snapshots, so it should not have that kind of performance hit.

You can also try to work with Veeam and Dell to figure out why you are having the problems you are experiencing.

it seems that there are many HP Left Hand customers that are very unhappy with what HP has done with the product line. I believe that is their P4000 line, not the P2000 that Andy recommended.

Read the comments and notice how they change as you get to more recent history after the HP acquisition.

Doesn't make any sense at all, the article and all the comments on it are from after HP bought LeftHand.

HP 2000 has business copy if licenses, replication will work fine.

Your budget might be light.  My favorite storage is NetApp but again your budget is nowhere near a NetApp solution.  I have a couple of Equallogic boxes now and they are OK iSCSI appliances, replication is possible.  

Look at QNAP,  it's a high end home system trying to penetrate the business market.  I also have a few of these and they are great bang for the buck.
