i365, a division of Seagate Technology Inc., is opening its cloud data storage
The i365 program is opening up integration that the company did with Microsoft's Data Protection Manager (DPM) to more partners with a standardized set of application programming interfaces (APIs).
According to i365 vice president of product operations George Hoenig, the APIs include file-related put/get operations through the REST protocol; metadata operations that allow for policy-based management of objects; business services that can request usage data and support chargeback billing; and a service connector that allows data deduplication, encryption and bandwidth throttling operations across a wide-area network.

Compellent Storage Center 5 adds portable volume option for replication
Compellent Technologies Inc. today launched a series of upgrades to its Storage Center SAN, adding a device for initiating data replication over low-bandwidth links, application-consistent snapshots, virtual ports, automatic discovery of virtual servers, and new support for RAID 6 and Serial Attached SCSI (SAS) disk drives.
Outside of the need to add an adapter to support SAS, none of the upgrades involve changes to the actual arrays.
Compellent has developed software that can automatically sync a volume to be replicated to a 1.5 TB or 2 TB USB drive, and then automatically sync from the portable hard drive to a secondary Storage Center disk array at a DR site. These "seeding devices" are designed to overcome bandwidth limitations in SMBs for initiating replication between sites. Without the devices, these initial replications can take hours, days, or weeks depending on the size of the connection.

Vendors take different approaches to automated tiered storage software for solid state drives
The rise of solid-state drives (SSDs) in enterprise data storage arrays last year brought about an emphasis on automated tiered data storage software to better take advantage of expensive SSD capacity. Compellent Technologies Inc. has had its Data Progression software out long before it started shipping SSDs, but competitors including EMC Corp. and Avere Inc. now say they've built better mousetraps.
Compellent's Storage Center SAN automatically tracks the use of blocks of data on the system and moves them between tiers of mechanical disk, SSD and RAID protection level. Customers set policies and schedule movement of data during low activity periods in the data center.
EMC Corp. last December came out with its Fully Automated Storage Tiering (FAST) software primarily for its high-end Symmetrix V-MAX arrays. EMC claims FAST can migrate data between tiers in real time.
Newcomer Avere also uses parallelization among disk drive groups and nodes in its scale-out network-attached storage (NAS) architecture to provide real-time migration between the top tiers of storage in its system.
Avere director of product marketing Jeff Tabor said Avere's FXT storage systems use solid-state tiers, DRAM, NVRAM, and Flash to optimize real-time movement of "hot" data.

RAID disk arrays in small-business data storage environments
RAID, the redundant array of inexpensive disks, first proposed more than 20 years ago as a better way to safely store data, is an idea that has won the hearts and minds of data storage professionals. It's everywhere. In essence, RAID has always promised to make data safer by not putting it all on one disk.
In 2010, RAID disk arrays still show up in the small- to medium-sized business (SMB) and prosumer market. In fact, according to analysts, when it comes to RAID purchases, the decision points are often rising above the level of RAID itself to strategy, architecture and new device choices.
Roger Cox, research vice president at Gartner, said he sees three big trends starting to impact those thinking about purchasing RAID. One is the advent of various storage schemes that add bells and whistles to the RAID formula such as mirroring layered on top of a traditional striping of data. But few of the additions in spinning disk capability impress him as much as the potential for marrying solid-state storage to disk -- producing ultra-fast IO while retaining the more favorable cost structure of traditional RAID.
