EVA4400 or P4000 G2? Getting conflicting advice, your thoughts?
I'm lookng at upgrading our storage, here's my set up at present.
2 x HP DL360's with 32GB each
1 x HP X1800 Storage server running iSCSI
So far everything seems to be working fine, but I need to virtualise more servers and am looking to now move to a dedicated SAN (though the X1800 has performed OK so far, it's iSCSI software can struggle under load).
I've got two HP Re-sellers quoting up a solution, one is based on using an EVA4400, the other is looking at the P4000 G2.
I need about 4TB of usable disk space, I need reliability, ease of management and most of all I need robustness.
All up I will need to support about 20 VM's and eventually want to deploy virtual desktops within the business, so the SAN we choose needs to be able to handle potential growth and increased workload in future years.
The P4000 will use iSCSI and the EVA 4400 will be using FC.
What do people here think? Some people tell me that the EVA4400 is near end of life and best to go with something newer, others tell me that they're quite solid.
Then i'm told by other people that FC is old hat and that we should all be on iSCSI, so I thought i'd post here.
What do you guys / girls think? Both seem to have advantages and disadvantages.
Interested in hearing from people who've used one or both of these or other SAN solutions.
Thanks.

There are volumes of information on iSCSI vs Fiber Channel. This was a good read just from a quick google search.

FYI. The 4500 series also gives you a license for HP's VSA (virtual SAN appliance) which lets you utilize existing hardware and storage as a SAN for up to 10TB.

If you buy a P4000: the performance stands or falls with the network. Watch out on this!

Why do so many people dislike the EVA4400? Is it just a badly designed unit?
Do you have any details on a likely replacement for the EVA4400?
Thanks.

If you are eager for experienceing some new Storage functions & technologies. Try P4000G2 - It can give you almost everything(Storage cluster, Network Raid, Snap & Clone, Thin provisioning, Remote copy...), it is full of FUN.

If you wanted to go with cheaper drives, you could buy some SATA and only one shelf, but wouldn't suggest this for databases.
If you need any DR/DT, add Continuous Access and another EVA4400 and replicate your data.
All in all, the EVA is an Enterprise array at a workgroup price.
