I would like to know if there is any difference in cabling between FAS series and V series as last week when i went to one of my client site to add additional disks to a V filer i got quite confused where lot of things came in to picture like LIMIT OF DISK SHELVES A V FILER CAN HAVE etc... I wanted to know if there is any cabling diff ... It will be very helpful if anybody can show some diagrams representing FAS and V connections.

This may be useful to you:
What are the cabling guidelines for Data ONTAP controllers when used with NetApp disk and third party storage arrays?
V-Series FAQ Covering Product and Technical Topics
WHAT IS THE MAXIMUM STORAGE CAPACITY I CAN ATTACH TO A V-SERIES CONTROLLER? (From the FAQ)
Each V-Series controller can support a maximum number of back-end devices that is equivalent to the number of disks supported on a FAS system. The devices can be either array LUNs from storage arrays or NetApp disks. For example, the V3140 can support 420 devices for a standalone system or for an active-active system. These 420 devices can be all NetApp disks, all array LUNs, or any mix of disks and array LUNs that does not exceed 420.

Also, refer to the V-Series support matrix, which documents the device limits for each platform per release.

There is no difference in cabling for native netapp shelfs for FAS and V-series.
If you are connecting a third party storage via the V-series, then the zoning and environment variables setup come into picture. The cabling for third party storage is different.
The LUNS from third party storage acts as disks by fronting thru the v-series, it is licensed feature.
Every third party storage has got limitations and consideration while connecting thru v-series.

Thanks you very much for clarifying this and i would like to know one more thing is there something like for a V-Series i need to have bunch of disk shelves ( ex:- 5 ) at a time coz i have heard like once you add disk shelves and do the cabling and now if you want to add more disk shelves one should not disturb the existing the loop to add new shelves in to existing stack instead we need open a new loop ????? Is that true ???/

You can add the disk shelfs to the existing loops as long as the max number of disk shelfs per loop doesn't exceed.(per loop 10 shelfs, best way).

Just to re-iterate what AK said - V-Series models supports the same disk shelves (limits) as the equivalent FAS models. I suggest you have a look at Netapp Hardware Universe . Limits on the speific v-series model you have may vary.
