Seagate has rolled out the storage industry's first one-terabyte hard disk drive in the 2.5-inch form factor. Squarely aimed at enterprise data centers and cloud data-storage applications, the Constellation 2 consumes just 6.4 watts of power on average when deployed in directed attached storage (DAS), network attached storage (NAS), and storage area network (SAN) environments, Seagate said.
Available with standard capacities of 250GB, 500GB and 1TB, the Constellation 2 is also being offered with 6Gb/s serial advanced technology attachment (SATA) or 6Gb/s serial attached SCSI (SAS) interface options, noted Seagate Vice President Carla Kennedy. "With its class-leading reliability, record-breaking capacity, and improvements made along its entire range of features, the Constellation 2 drive is a perfect solution for dense server and storage systems," Kennedy said.
Delivering More Options
IDC projects that hard-disk drive shipments for enterprise applications will increase from 40.5 million units last year to 52.6 million in 2014. What's more, the research firm expects the HDD industry to ship more petabytes for enterprise applications in the next two years than it did in the preceding 20 years.
"We're definitely seeing intensive cost-cutting measures among end users striving to bring more efficiency to current solutions," said IDC Research Manager John Rydning.
With Constellation 2, Seagate's goal is to fulfill the needs of data-center managers looking for more efficient storage technologies that meet their capacity growth requirements, Rydning noted. "Reaching the 1TB capacity in a small-form-factor design gives IT managers more options to meet capacity requirements with efficient storage platforms," he said. "IDC expects the use of capacity-optimized drives like Seagate's 1TB Constellation 2 to increase by more than 50 percent from 2010 to 2014."
Among other things, the 2.5-inch drive's small form factor will help enterprises maximize their data-center footprints by supporting densities of up to 76TB per square foot, noted Seagate Senior Product Manager Barbara Craig. And since the drive consumes less than 6.5 watts on average, IT department can save up to 72 percent over what a 3.5-inch drive typically consumes.
Seagate's Constellation 2 is on the leading edge of the industry's transition from 3.5-inch to 2.5-inch drives, which IDC expects to be complete by 2012. "Available in the channel now, it's the only drive on the market that can service your high-capacity needs in an efficient, low-power 2.5-inch form factor with the high 1TB capacity point," Craig wrote in a blog.
The Constellation 2 enhances data integrity by harnessing the power of T10 Protection Information -- a new SCSI-based end-to-end data-protection specification that enables each element in the data's path to inspect the data and verify that no corruption has occurred. Moreover, device reliability has been boosted to a mean time between failures of 1.4 million hours, Craig noted.
Enterprises today are very concerned about the potential loss of proprietary corporate data as well as customer records that include sensitive personal information such as credit-card numbers. Seagate offers a self-encrypting drive (SED) option for the Constellation 2 that will automatically lock the drive and secure the data the moment it is removed from a system. Additionally, SED reduces the cost of disposing or reusing any drive by enabling IT workers to cryptographically erase the device in less than a second.
Dell is slated to begin shipping systems featuring Seagate's Constellation 2 drives later this month, noted Lewie Newcomb, Dell's executive director of storage core technologies. "The Dell PowerVault storage enclosures and PowerEdge servers are being enabled for even more powerful storage alternatives," Newcomb said.
