Cache in Storage array

Question

Hi I just started working in a Storage Lab.

I am new to Storage Area Networks, I did lot of searching on Internet about this.

I have two doubts :

How can we know whether a Storage array has a cache or not. (with iSCSI protocol)

How to know if any new device is added to storage array.

Any help would be greatly appreciated.

It has to be documented by the administrators, there is no way to see this.

How to know if any new device is added to storage array.

E.g. with the help of something like iSNS, but this will dependent on your local configuration. Again, documentation is important as well.

Hmmm, I knew so thats why asked whether there is any way to find out or not, ( what if your s/w has to be independent of the storage array and has to work in all cases ). – user1457896 Jun 16 '12 at 18:22
