Why not RAM? Build a box w/256G or more, and keep them all in tmpfs during operation. (ditch Solaris. It was cool once, but...)
Copy them up into tmpfs on boot, then cron an rsync to disk between polling or even occasionally, depending on pain tolerance.

Hmm, well, I could only steal a machine with 64GB of RAM this time, but
ZFS
- SSD cache + regular spindles sounds cleaner that rsync of 150GB every
2
hours..
Why the SSD cache? Why not just use the SSD.
Having the filesystem layer dealing with the caching is likely to add even more overhead, you're also relying on the cache to actually cache the things you are accessing. I would first ditch Solaris and see if the performance changes.
How long does it take to run /one/ instance of the poller?
