Seagate's Savvio 10K.2 hard drive
Seagate goes green with low power consumption 10,000RPM SAS drives

Seagate Technology today announced its Savvio 2.5-inch 10,000RPM enterprise hard drives.  The company announced its first 2.5" enterprise drives late last year with the Savvio 10K.1 series, which were also some of the first drives on the market with perpendicular recording capabilities. 


Savvio drives consume less power than equivalent 3.5-inch drives -- 5.7W for 143GB, 5.4 for 73GB at idle -- thus reducing system temperatures while the smaller size enables more airflow to cool processors. Seagate boasts its “greenness” in the enterprise by working to address power and cooling challenges that data centers encounter.


Smaller platters ensure faster seek times (3.8/4.4ms), while the compact chassis enables more drives per system to maximize IOPS/U performance. Savvio drives also make room for additional memory modules and processors.   The new drives are available with SAS, SCSI and fiber channel interfaces.


Seagate claims that its Savvio 10K.2 drives have an average failure rate of only 0.55%, even when running 24/7, making it the most reliable disk drive in Seagate’s roster. In addition, non-recoverable error per bits read rate has been improved to one sector per 10^16.


Seagate is quick to point out that its Savvio drives differ greatly from other 2.5-inch notebook drives. The Savvio line was designed from the ground up as an enterprise class drive, sharing more in common with the Cheetah than the Momentus.


Enterprise storage customers are juggling demands for space and power in addition to improved performance and cooling efficiencies in data centers,” according to John Rydning, IDC’s research manager for hard disk drives. “A growing number of customers are beginning to realize the benefits of a smaller 2.5-inch form factor enterprise hard disc drive as a solution to these datacenter challenges.”

RE: When, what capacity - what about NOW?

20+ drive bay chassis units have been in development by the big manufacturers for several years now. HP have released the first of several new SAS/SATA cabinets (the MSA60) planned for sale in CY2007. One unit that was demo'd almost 3 years ago had 25 drive bays.

One thing that is probably going to (slightly) delay a steady release of new storage enclosures from the big boys is the push for dual ported SAS drives and storage enclosures.

As for capacities, 2.5" drives will be 1 - 2 years behind the 3.5" drives in terms of capacity bumps.

For what you are talking about (high capacity SAS type drives), you need to look at things like multiple HP MSA60 enclosures (3.5" low profile SAS HDDs) and the SA-P600 and SA-P800 controllers.

I'd like to ask for clarification
"One thing that is probably going to (slightly) delay a steady release of new storage enclosures from the big boys is the push for dual ported SAS drives and storage enclosures. "

I'm not sure what you mean to say but I think it'd be worthwhile for me to be clear.

Single ported SAS is the current standard, but it is really meant as a waypoint rather than the destination, at least for enterprise class implementations. The eventual goal is to have dual-ported SAS for mainstream enterprise level consumption and use because it allows for the design of products that provide maximum capacity, minimum footprint, and high availability (duplexed controllers - no OS software mirroring).

If I want to build an HP server that has, say 1.3TB of storage and the server must have redundancy / fault tolerance in the storage subsystem, then I can buy the MSA30 Dual Bus cabinet and fill it with 300GB drives. But in order for me to do this using the MSA50 (SAS Small Form Factor) or the MSA60 (3.5" SAS low profile), I'd have to buy two storage cabinets. The cost for this solution increases the overall server price by about $2,000 and my company gets significant discounts from HP because we buy thousands of servers a year. So for companies like us, it is important that HP's future releases (the MSAx0 and the SAS SFF version of the MSA500) are dual ported.
