Hello, SP is enabled for "server only" Deduplication is there any benefit or caveats to enabling SVC compression on the V5K storage pools ?
You need to choose one =)
By way of SP deduplication or by SVC. Deduplication will require compute and is running in the background. In our production, we let the storage system (e.g. FS5010, FS7300) do the dedup. This way, we let SP do the other stuff.
I hope this helps.
What is your dedup ratio on your 5010 and 7300? I use SP deduplication and it's very efficient (4,5:1) we are backing up mixed vmware environment.
Almost the same using our storage. The upside when using the storage, it free up processing power on the SP server.
It is like Bobby says.
Same goes with letting Spectrum Protect compress an already compressed file, as it is by having the hardware to compress an already compressed file, it might become larger.
If you are interested of what more you can do with Spectrum Protect, than take a look at Spictera SPFS, or Spictera Snapshot
I guess this is more of how your infrastructure is designed. We run the same config, with storage behind an IBM SVC SV2. This unit does not do anything of dedup/compression, as most of our clients run client side dedup/compression or encryption. The gain in space of having svc doing further compression/dedup is therefor low in our case. And it will only run the CPU very high, and slowing down other IO.
If you have sufficient bandwidth from client to SP server and are not doing any spacesaving, then you can let the storage do that for you. Just watch the CPU util.
I do not think there is a final answer, just a few advices that can be evaluated.
