Hi folks,
We have the following disks :and we want to create a STRIPE
c7t2d0 c7t3d0 c7t4d0 c7t5d0 c7t8d0 c7t9d0 c8t2d0 c8t3d0 c8t4d0
c8t5d0 c8t8d0 c8t9d0
What we would like to measure is how the following two STRIPES perform
STRIPE ( Created using Solaris Volume Manager ) STRIPE created with ZFS.
How can I acheive the exact STRIPE ( w.r.t to the interleaving,
stripe size, etc... ). We want to make sure that the two STRIPE
configurations are identical. Any pointers ?
This is not possible because SVM uses a fixed stripe allocation and ZFS
uses dynamic stripe allocation. Reads and writes for ZFS will only use
the number of disks needed, not all of the disks (every time) like SVM.
In other words, it is like comparing apples and oranges, at least as far
as RAID implementations is concerned.

hi Richard,
Please suggest an alternative ?. Please advice on whats the best course
of action
What are you trying to accomplish?
The PAE group in Sun has a team working on ZFS performance and characterization.
Some results have been blogged externally. It may be that your question is
already answered someplace.
