Choosing a SAN Solution


I am going to be building out four data centers and need to purchase a SAN for each one.  The approximate size of each SAN will be approximately 12 - 15TB of usable space.  I have familiarity with the HP EVA's but I'm not sure if they are up for this task.  I am interested in knowing your opinions regarding SAN's.  Which equipment should I use?  I'm not only interested in dependability, I am also in need of quality phone and onsite support.  Any recommendations anyone could provide would be greatly appreciated.

EMC CLARiiON CX3-20C, CX3-40C or CX3-80C (http://www.emc.com/products/systems/clariion_cx3_series.jsp) all offer high availability, excellent support, support for the great bulk of common operasting systems and excellent performance.

NetApp's FAS3000 and FAS6000 range (http://www.netapp.com/products/storage-systems/enterprise-storage/index.html) also offer pretty much the same. For ultimate performance, though, I'd go with EMC.

Then there's HDS (http://www.hds.com/products/storage-systems/) - any of their boxes except the WMS - which only supports SATA drives. Sun resell HDS storage systems. IBM have the FASTt range (although I believe they've renamed them) which are rebadged Engenio storage systems.

All the main vendors offer snapshotting software, synchronous and asynchronous mirroring, array management software and so on. HDS are the odd one out in that they charge extra for the array management GUI, without which you have to do everything via CLI. Bit strange, really.
I'm using EMC clariion for the last 2 years.
It provides a very easy to use mangment panel for snapshoting and and configurations.
It is also very modular and easy to upgrade.
You can use either SATA, Scsi or optical disks.
The system fully redundent (no single point of failure).
I warmly recommand

EVA is certainly up to the size, should be up to the I/O as well with 225,000 iops and 2450 MB/s although you won't get that unless you populate a 8100 fully. As long as you have the correct carepack the support is normally OK and it can be configured to log its own faults back to HP although it's VPN now rather than modem.
