Since most of our customers are predominantly UFS based, we would like to use
the same configuration and compare ZFS performance, so that we can announce
support for ZFS.
We're planning on measuring the performance of a ZFS file system vs UFS file
system.
Please look at the following scenario and let us know if this is a good
performance measurement criterion.
Also I read in the ZFS Administration guide that the "
You can construct Logical Devices for ZFS using volumes presented by
software-based volume managers, such as Solaris Volume Manager or Veritas
Volume ManagerVxVm. These configurations are not recommended. ZFS might work
properly on such devices, but less-than-optimal performance might be the
result".. so with this in mind.
ZFS vs UFS/SVM:
UFS File systems are created using SVM
ZFS File systems are created using the disks.
So using the same disks eg.... c0t0d0 / c0t1d0 / c0t2d0 / c0t3d0
1) Create STRIPE
2) Create Mirror
3) Create RAID-5
And run bunch of performance tests. We're using SWAT for measuring I/O.
