Thank you. A couple of you folks I need to follow around on the boards. We are not sure we are provisioning the datastores correctly. Some do this, some do that.
After having a read the link you posted we found that we do have a couple IBM 12G SAS SSDs here that were listed as heavy write drives.
Thanks again.
Happy to help if you want to spin up a new thread summarizing the current configuration, so that it doesn't get lost in the mix here. I do see a couple concern points from your description (eg: RAIDZ2 pool for block storage) - check out the resource called "The path to success with block storage" for some basic information about why mirrors are significantly better than RAIDZ for this.
The path to success for block storage
It seems like I haven't written a sticky for awhile, but just in the last week I've had to cover this topic several times. ZFS does two different things very well. One is storage of large sequentially-written files, such as archives, logs, or data files, where the file does not have the middle...

Let me take some time to look over your system config and see if I can propose a different/improved mix. You do have six PCIe x8 slots and onboard SAS2008 which gives us a good amount of expansion/upgrade potential. Feel free to @ tag me into your new thread when/if you create it.
