Copan gives its MAID more cache

Copan has enhanced its Revolution 300 Series to beef up its virtual tape library capabilities (VTL) and try and keep distance between the MAID pioneers and those who have followed with disk spin-down products.

The most interesting Revolution enhancements involve data deduplication that Copan added late last year for its VTL via an OEM deal with FalconStor. Now Revolution customers can set up a 40-drive cache landing zone, which supports more than 1,000 concurrent data streams. Up to 40 drives will run separate from the MAID pool, so those drives always spin and increase the ingestion rate while deduping. The cache will spin down with the rest of the drives after it finishes ingestion.

Copan also added a hot standby deduplication option that provides a spare dedupe engine that replaces a failed unit for high availability deduping.

Other enhancements include support for 1 TB SATA drives that bring maximum capacity to 896 TB in a single frame, data shredding to destroy tape data and tape caching to automate moving data from the VTL to physical tape.

Copan was the first to deliver MAID systems in 2004, but rivals Nexsan, Hitachi Data Systems, and EMC have since come out with their own spin down drives. But Copan CTO and founder Chris Santilli says there is more to MAID than spindown, and the new enhancements make Copan’s MAID more enterprise ready than the competition.

“MAID does not equal spin down,” Santilli said. “There’s more to it than saving power by spinning down drives. Enterprise MAID is a combination of density and reliability, and adding software services and features. We ingest as fast as we can, stage the data on MAID, and now we can do dedupe, replication, and encryption on the data.”

Analyst Mark Peters of Enterprise Strategy Group agrees the caching and other enhancements make MAID more valuable than merely spinning down disks.

“Caching shows they understand there are people who want to get a lot of data in their system fast,” Peters said. “If 25 percent of your disks are doing something else, that creates a problem. They created a side stream to the main river. This is a special section where you can keep the drives on.”

    Does anyone have experience with Fujitsu's MAID as part of their Eternus storage? It looks really good and they don't charge extra for it.
