Can I completely separate 2 storage areas in the same EVA4400?
Hi,
We are going to procure 2 EVA4400, we have 2 Data Centers, so 1 for each Data Center, and connected between them through a FC switch to get replication, business continuity and so.
We have 2 Departaments and I would like to know if it´s possible to separate the storage area of both departaments, but sharing the same pair of EVA4400. One department is asking me for P2000 for their systems (exchange,data server...) and the other department is asking me for EVA4400 for their systems (corporate applications,...)....so I am wondering whether we could use the same pair of EVA4400 (active and standby), but differentiating the physical storage blocks, so every department would have their own physical storage area.
I guess the only issue to bear in mind is the growing needs of every department...since EVA4400 limit is 96 TB, isn´t it? Or when the time came, we could buy other 2 new EVA4400.
Thank you

Thank you andyalder, but since I am new at storage systems, I have more questions after reading your comments:
-Two disk groups means two physical separate storage area in the same device?
- What is a LUN? LUN means that no separation of physical storage would exist?
- What is a distributed hot spare?
- 96TB implies using FATA then, right? what other disk are available with EVA4400? By your words I supposed they have less capacity than FATA disks.
- Is maybe the point that there is no reason why we should separate physical storage of both departments?
Thanks. And sorry for the language, some terms are difficult to me in English.

Simply a perfect answer. Thanks.
We need a SAN, a NAS is not enough since we are using several database servers, 2 data centers and different systems: oracle, business objects, exchange server, personal files, corporate files...

An EVA4400 can be upgraded to EVA4600 or EVA4800 to allow for more disks by changing the controllers, it's quite a job though. I hesitate to say 96TB max capacity as that would involve using slow FATA disks which is a bit of a waste of an EVA.
