New Q3.4.1 code out now for the 7000 ZFSSA family
By Steve Tunstall on Sep 12, 2011
Code release Q3.4.1 is available now on MOS for download.
This is very exciting news, even if you don't need to upgrade. Why? Because Q3.4.1 contains NO bug fixes. The only thing it does is allows your system to use the new drive trays with 15K speed drives.
You can mix-n-match drive trays in the same system, and create a new, faster ZFS pool using the 15K drives in the same system you already have. You do not want to mix the high-capacity, slower drives with these in the same pool, however. Make sure they are different pools to be most effective. Not everyone needs these faster drives to drive their performance, as the ZFSSA really tries to drive performance with it's huge amount of L1 and L2 cache. However, some people run workloads that either fill up the cache, or by-pass the Logzillas during writes altogether, and the faster, 15K speed spindles will matter a lot to them.
