im after a san for the company and want to know what id actually need to get


connecting to 5 servers
only about 2tb of data at the mo but id also like it to do backups 2 (possibly) times daily snapshots to disk with an incrimental backup every nightand a tape backup once a week but i also need the san to replicate to another san of the same spec down fiber to our head office on maybe a 5 minute delay if possible

We're using MSA1500's with MSA1000 controllers, with 2 shelves of 146gb disks (11 in each, IIRC but theres room for more)

We have that duplicated in 2 different server rooms, will be connected to a tape library once we decide what we want.

you really need an EVA rather than an MSA to do that mate.

MSA is not really designed for snapshoting and replication really.

2 EVA 4100's, unlimited business copy license and continuous access licenses either end.

that will replicate synchronous or asynchronous and provide you with any type of snapshot you ever wanted.

thinking about it though, if you did want to do iton the cheap you could use an MSA1500 with an MSA30 shelf with 15k scsi disks and then an MSA20 with some SATA discs (for the backup to disk and snapshoting).

Then use host based replication like Doubletake (the EVA uses array based replication)

Then for the snapshoting use windows VSS or something from Symantec/backup etc.

But the EVA is the proper way to do it.

and whats wrong with me?

I'm a HP storage and server pre-sales consultant working for a leading HP reseller, I just recently specced up and sold a 1m+ server blade and EVA solution for EDF Energy so I am qualified to recommend something.
