I'm trying to look for some SANs that support replication, next year we're hopefully getting two identical SANs to use as vm storage to make all our servers driveless boxes and allow for expansion.

Ideally im looking for something supporting SATA drives but SAS is a possibility if there aren't any supporting SATA drives, seems anything that supports it aren't cheap either, so can anyone recommend any makes and models of boxes that support replication and some idea of how much they cost?

EDIT: just lookin at a netgear readyNAS 4200...
Remote backup to another ReadyNAS via rsync and secure rsync
Multi-system cloning

is that their way of saying it does replication or is that something else altogether? I've never used a netgear readynas, always used infortrend eonstors.

Ideally we're looking to spend £15k or less for two boxes, whether this is realistic for what we want i'm not sure though. Looking at the price of those HP lefthands it's probably not very realistic :p

We use an infortrend Eonstor A16E-G2130 at the moment which will continue to be used as the file storage but i want something a bit more special to put all our VMs on and i want reliability through redundency for the VMs. I could get an identical eonstor for £4500 including 32TB of space which is a bargain but the box just lacks the ability to make me feel safe in the event of a controller or other failure.

It might be that two replicating boxes is overkill and that a box with both redundent power and controllers would be good enough for our needs, i think i need to do some more investigating.
 
Are they easily expanded? i know nothing of lefthands, never seen one let alone used one, any spec/tech sheets you can link me to?

the actual storage is normally dead cheap, do you have to buy hp caddies/drives for them?
 
Ah i get you now, well for our requirements the smaller lefthands would be sufficient so perhaps they are a pretty viable option :)

If you could email me some details to my trust that'd be brilliant, cheers nikumba
 
Looking at the "Lefthand P4300 G2 7.2TB SAS" system, all the pictures on all the sites show what looks like two boxes. Do you purchase these in pairs or is that just the funny way they've made them look?
 
ooo thanks for all the suggestions, i'll investigate them all thoroughly before we make a final decision on which one to get :)
