EVA6100 with NAS

Anubhav Dhingra — Mon, 11 Aug 2008 18:10:13 GMT

I am not sure if my question is right or some thing. However, what do we mean by configuring EVA6100 with NAS. This EVA would be running on HP-UX environment (Entry Level Servers rx3600 or rx2660). Also can we manage 2 EVAs with one Storage Server running Command View or we need individual servers running CV.

You need to explain the question a little more. The EVA6100 is a disk storage system and serves space by blocks. A NAS serves disk space though SMB, FTP, or other network protocols.
You can present the disks in the EVA to a server, and then share the space over the network. This is known as an EVA gateway.

Regarding the Command View question, yes, you can manage several EVAs from one server, up to 8.

You can manage the 2 EVA with one Command view server...

hi;
EVA disk arrays use SAN.
You can add hosts to the EVA directly or with using SAN switch.
if you wanna use EVA at NAS system you have to use Network file servers.
these servers may use EVA's virtual disks and NAS clients may use the Network file servers.

here there is an image, check it pls to figure out what i try to say.

Hi Mustafa,

Thanx for your reply. However, i am not able to understand why do we need this kind of setup, connecting storage to file servers only and then connecting clients using NFS/CIFS etc.

Hi,
NAS is useful for the hosts which dont have the direct SAN connectivity (HBAs). Therefore the server which has it, is in a role of SAN/LAN gateway and he propagates its SAN LUNs as a CIFS/NFS shares.

Hi,
If your fileserver has an Host Bus Adaptor, sure you can connect it directly to the EVA.
