We currently purchased 2 Netapp 3050 Filers for CIFS, FC, and ISCSI. We also have the Snapshot feature, but are not using it at this time. Now we are looking into a VTL for local recovery.
Here's our dilema. Why not forget about the VTL and take advantage of the NETAPP's SNAPSHOT functionality. We have an instant snapshot of our data which we could recover back to if there was a file deleted or if there was any data corruption. The filers are redundant and the filer storage is raid-dp protected, so shouldn't that be sufficient protection ???
We are having a serious debate over this issue. The debate revolves around putting all our eggs in one basket. Thinking if both Netapp filers fail or if 3 disks fail within one raid group, we have no local recovery.
Should we be concerned about the chances of such a scenario ??? Are the NETAPP filers and attached FC/SATA storage that volatile ???
Any thoughts on this dilema would be greatly appreciated.
