Hi,
I have this Nexenta ZFS on my ESXi (5.5, server has only 16 GB) deployed, nfs enabled for my vm's.
Practical questions:
*I only granted Nexenta 3 GB but performance is really for crying out loud, what can I do to optimize performance on vm ... besides granting more ram?
*does installing vmware tools help on performance? installed it before (with lot of hassle) but vmxnet 3 adaptor is not supported
*I wanted to install Nexenta to hardware mapped laptop disks (mirror), this didn't work, is it a supported config/should it work ... should I?
*any special configs on Nexenta for performance optimization?
*the Nexenta zfs is on 1 SSD, can I backup the configs and use for disaster/recovery?
*Please check config, looks fine to me:
*Update: raised the ram to 8GB and ran another vm (Windows 2012) from another machine, still terribly slow (still booting -for 10 minutes now-) .... What a dissapointment.
Increasing the amount of memory for the appliance will help, as it uses memory for cache.
As much as you can assign, 8-16GB is not uncommon for an appliance.
Assigning SSDs for LOGs and ARC can also help, but you would probably see more performance increase using SSD with traditional rotational hard disks for ZFS.
Adding more drives for ZFS, e.g. four SSDs, configured as two mirrors.
VMXNET3 is a better vitualised network interface than the E1000, if you can get it to work!
It should work.
see above for performance tweaks (also jumbo frames)
more disks, would give you more IOPS.
