Someone had tell me that s10u5 will not contain your need SSD or NVRAM separate for zfs intent log. Finally, s10u5 will only contain a small part of bugfix. But s10u6 will be a quite huge wad of features/fixes. Set nocacheflush=1 will huge improve your nfs client's performance when use a

Don't take my words as an expert advice, as I am newbie when it comes to ZFS. If I am not mistaken, if you are only using Oracle on the particular Zpol, Oracle Checksum offers better protection against data corruption. You can disable ZFS checksums. Best regards Mertol Mertol Ozyoney

This is true, but I think it's the testing bit that worries me. It's hard to lab out, and fully test an equivalent setup that has 350 active clients pounding on it to test usability and stability. One of our boxes has a boat load of special software running and various tweaks, that also
