Hello All,
We're migrating from a FAS to a new AFF that has inline compression and a guarantee of 3X compression.
I'm trying to convert a graphite/snmp graphing system that reports our overall aggregate space usage to the new system.
A straightforward graph of used and free space on the data aggregates/tiers shows the right portion of space used but seems to be reporting pre-compression usage (and we appear to be getting less than 3X).
The System Manager webUI says we're getting ~120:1 "Data Reduction" but it also says we're using 1.74PB and have 14TB available. In fact we currently have 48 x 900GB SSDs in two disk groups/tiers and about 40TB of actual unstructured data.
Is there a doc somewhere on understanding space reporting with the new system including meaningful reporting of compression returns?
Grateful for any help,
Randy in Seattle
