What issues, if any, are likely to surface with using Solaris

works great in vmware server, IO rates suck.

I'm assuming that ZFS's ability to maintain data integrity
will prevail and protect me from any problems that the
addition of vmware might introduce.


no problems so far, created two  virtual disks and  concat, its just a
toy/test bed for nexenta, only problem I have with nexenta is that the 64bit
mode crashes on boot. b55  may be fixed who knows.

Are there likely to be any issues with disk drive IO
performance?


i'm getting  11MB/s on bonnie++, the disks are backed by sata drives on a
ultra 20 2.6ghz and has  512MB allocated.


not exactly a speed demon it would get about 130MB/s on the raw hardware.

The concern here is with comments on how ZFS likes to
"own spindles" so that it can properly schedule I/O and
maximise performance.

Any other gotchas, such as the extra vmware layer doing
buffering that ZFS isn't aware of, etc?

If there are problems, are they likely to be any better/different
when using ZFS and Solaris as a Xen domU?
