Infrastructure Software

Hi, I'm guessing there is probably a simple answer to this but Google and I haven't found it.

With OpenSolaris svn_111b, the GNOME System Monitor would show almost all memory consumed. (By ZFS cache...a good thing.)

With Solaris Express svn_151a, System Monitor shows <1gb (out of 16gb) consumed.

Would I be correct in assuming that ZFS cache is no longer counted in the System Monitor, but ZFS is still using almost all available memory (hopefully)?

The reason for concern is that with svn_111b, I was getting a reliable 90 MB/s transfer over SMB (with Solaris as Samba server), without even jumbo frames. But now, on the same server and network config but with a clean install of svn_151a and minimal tweaking, I'm getting terrible performance at about 3 to 10 MB/s.

(I've posted the performance problem specifically as a separate post, so as not to double-post I don't want to dwell on that here - this is just about the System Monitor / ZFS cache question.)

Thanks!!

Specs, if it matters for this question:

Machine:
- 2*4-core Xeons
- 16gb ECC RAM
- Onboard e1000g NIC
- 20 hot-swap bays
- cooling out the wazoo

rpool:
- mirrored 30gb SSDs

Pool "zp3" config:
- LSI SAS1068E-R c9 HBAs
- 6 * 3-way mirrors, 1tb, 7200 RPM enterprise-class SATA
- 2 hot spares
- 2 * 30gb SSD for L2ARC

Pool "zp3" settings:

Type of data and access:
- Mostly large media files (DNG photos, large photoshop project files, high bitrate 1080p video, 32-bit/96khz audio, etc.)
- Plenty of small "office" data files too, but of secondary importance.
- Low usage. Typically accessed by one CIFS/SMB client - and one application - at a time. Needs throughput, not IOPS.
