memstat ZFS File Data value is high

edited Dec 4, 2015 10:20AM in Oracle Solaris Performance, Panics, Hangs, and Dtrace (MOSC) 2 commentsAnswered ✓

I ran memstat on my Solaris 11.2, Sparc T5-2 server and it is showing a low value on free memory availability.

In the table I noticed the value on ZFS File Data is 170G.

Is this normal?

Does this mean there is something not quite right in the configuration?

Will this be impacting on my server performance?

This server is only running 4 zones, and only has 4 zpools for these zones and only has 76 zfs datasets.

echo ::memstat | mdb -k
