Dear all,
I have a hardware based array storage with a capacity of 192TB and being
sliced into 64 LUNs of 3TB.
What will be the best way to configure the ZFS on this? Of course we are
not requiring the self healing capability of the ZFS. We just want the
capability of handling big size file system and performance.
Currently we are running using Solaris 10 May 2009 (Update 7), and
configure the ZFS where :
a. 1 hardware LUN (3TB) will become 1 zpool
b. 1 zpool will become 1 ZFS file system
c. 1 ZFS file system will become 1 mountpoint (obviously).
The problem we have is that when the customer runs the I/O in parallel
to the 64 file systems, the kernel usage (%sys) shot up very high to the
90% region and the IOPS level is degrading. It can be seen also that
during that time the storage's own front end CPU does not change much,
which means the bottleneck is not on the hardware storage level, but
somewhere inside the Solaris box.
Is there any experience of having the similar setup like the one I have?
Or anybody can point me to an information on what will be the best way
to deal with the hardware storage on this size?
Please advice and thanks in advance,
Dedhi
