New code and new disk trays !!!

Hey everybody, happy new year and some great news for the ZFSSA...

The new 2u disk trays have come out early. I was not expecting them until later this quarter, but was surprised yesterday that Oracle announced them ready for sale. Sweet. So we now have a 4u capacity tray for 3TB drives (soon to be 4TB drives), and a 2u high-performance tray with either 300GB or 900GB 10K speed drives. These new 900GB 10K speed drives have the same IOPS as our current 600GB 15K speed drives, since the form factor went from 3.5" to 2.5". So you now can have 24 drives in a 2u tray. Very cool. These new trays require OS 2011.1.5, and right now you can NOT mix them with the older DS2 trays. Being able to mix them will be supported later, however.

To go along with that, the new 2011.1.5 code has been released. you can download it right now in MOS. It fixes a ridiculous amount of  issues, as well as supports these new 2u drive trays. You can read all about the new code here: https://updates.oracle.com/Orion/Services/download?type=readme&aru=15826899

Enjoy! 

**Update 1-18-13 - I need to correct myself, and I'm adding this note instead of changing what I wrote up above and trying to hide that I messed up... Hey it happens...
At first I was lead to believe the the smaller size platter made up for the slower speed on the new 2.5" drives. This is not the case. It does help, but the 10K speed drives do get slightly less IOPS and throughput then the 3.5" 15K speed drives.  Not that this matters too much for us, since we pride ourselves on the fact we drive performance with the ZFSSA via our cache, not our spindle speed, but it's important to point out.  Now, the power savings and space savings are real, and very much worth using the smaller form factor. Also, you do understand that Oracle does not have a whole lot to do with this? This is the way drive manufacturers are going. They just don't make 2.5" drives at 15K speed. So this is the way it is. Now, at some point sooner rather than later, we will also be putting out an all SSD tray. So if you need fast IOP speeds on the spindles, we will have you covered there, too.
