New Write Flash SSDs and more disk trays

In case you haven't heard, the Write SSDs the ZFSSA have been updated. Much faster now for the same price. Sweet.

The new write-flash SSDs have a new part number of 7105026 , so make sure you order the right ones. It's important to note that you MUST be on code level 2011.1.4.0 or higher to use these.

They have increased in IOPS from 6,000 to 11,000, and increased throughput from 200MB/s to 350MB/s.  

 Also, you can now add six SAS HBAs (up from 4) to the 7420, allowing one to have three SAS channels with 12 disk trays each, for a new total of 36 disk trays. With 3TB drives, that's 2.5 Petabytes. Is that enough for you?

Make sure you add new cards to the correct slots. I've talked about this before, but here is the handy-dandy matrix again so you don't have to go find it. Remember the rules: You can have 6 of any one kind of card (like six 10GigE cards), except IB which is still four max. You only really get 8 slots, since you have two SAS cards no matter what. If you want more than 12 disk trays, you need two more SAS cards, so think about expansion later, too. In fact, if you're going to have two different speeds of drives (in other words you want to mix 15K speed and 7,200 speed drives in the same system), I would highly recommend two different SAS channels. So I would want four SAS cards in that system, no matter how many trays you have.

New SSDs announced today

Thought you should know about the 3 new announcements for the ZFSSA.

--Write-flash-cache SSDs have gone from 18GB to 73GB each.
--New long-range transceivers for the 10GigE cards are now available
--3TB drives for the 7120 model are here today. The 3TB drives for the 7320 and 7420 are NOT here yet, but close.


Overview
Effective December 6, 2011, we are pleased to announce three new options for Oracle’s Sun ZFS Storage portfolio:
1. Availability of a 73GB Write Flash Cache for 7320 and 7420.  This new SSD features 4X the capacity and almost double the write throughput and IOPS performance of its
predecessor.  In comparison to the current 18GB SSD, this new 73GB SSD significantly enhances the system write speed.  As an example, a recent test on a particular 7420
system demonstrated a 7% improvement in system write performance while using half the number of SSDs.  The 73GB SSD is also available to our customers at a lower list
price point.  This is available as an ATO or X Option.
2. Availability of the standard Sun 10 GbE Long Range Transceiver for the current 1109A-Z 10GbE card as a configurable option for ZFS Storage Appliance.  This Long Range Transceiver enables 10 GbE optical connectivity for distances greater than 2 KM.
3. Availability of a new 7120 base model featuring integrated 11 x 3TB HDDs and a 73GB Write Flash Cache.  (Note that availability of the 3TB drive is limited to the 7120 base model internal storage only – it is not available in the disk shelves at this time.)


Additionally, we are announcing End-of-Life for the following two items:
1. 2TB drive-equipped base model of the 7120, with a Last Order Date of December 31, 2011.
2. 18GB Write Flash Cache, with a Last Order Date of January 10, 2012.
