My company will be acquiring the Sun SE6920 for our storage virtualization project and we intend to use quite a bit of ZFS as well. The 2 technologies seems somewhat at odds since the 6920 means layers of hardware abstraction but ZFS seems to prefer more direct access to disk.
Yes, and then again, no. What you have with the SE6920 is a rack which provides you with hardware redundancy and whopping great cache. For my money, as long as you configure multiple paths from your attached hosts and ensure that each lun the SE6920 presents has at least two paths to your ZFS host, then you should be just fine.
I tried to search around but couldn't find any performance numbers of ZFS on SE6920 nor any recommendations where to start or what the considerations could be. Will appreciate any hints in this area.
Ah, well that really depends on what your target usage mode is, and what you really want to achieve. With a hw raid array you've got a lot of knobs to tweak (so to speak), and you can also decide between mirrors and raidz/raidz2 with zfs. I suggest that you contact Roch Bourbonnais or Richard Elling since this is really their area. (They're both @Sun.COM btw). best regards, James C.
