Reduxio's HX550 Flash Hybrid storage system uses what the vendor refers to as BackDating to enable users to recover data from any point in time. BackDating works like built-in continuous data protection (CDP) for all applications. It allows for unlimited snapshots to enable users to roll back to any second in time.
Mark Weiner, Reduxio's founder and CEO, called the HX550 "basically one big database" that combines inline dedupe and compression to save space and constantly track history.
"Whether you're taking a look at your data from now or from 45 minutes ago, 45 hours ago or 45 days ago, we can instantaneously provide you all those copies of the data because we're always recreating the block anyway," Weiner said.
He said the system breaks incoming data into 8K blocks, dedupes/compresses each 8K block in buffer before it hits the memory, stamps every block as unique, then virtualizes and categorizes the blocks in the database. The system keeps a separate set of metadata that includes the log indicating when the blocks were written and synchronization information.
"You have a system that can keep unlimited amounts of snapshots, and the snapshots basically go to disk drives eventually, so it’s not expensive. And they're all deduped," Weiner said.
Weiner said the system writes the deduped/compressed data to flash first, and all active data sits on SSDs.
"We're an all-flash system that offloads to the disk drives," Weiner said. "In our system, when we write something to our SSD, it's not on the disk drive, and it might never be on the disk drive."
The Reduxio HX550 is a 2U box with 24 slots for hard disk drives (HDDs) and enterprise multilevel cell (eMLC) SAS solid-state drives (SSDs) from Western Digital's HGST division. The maximum raw capacity is 40 TB, but Weiner said the effective capacity ranges from 100 TB to 150 TB, depending on the data reduction ratio for the data set. HX550 systems typically consist of about 25% flash and 75% HDD, according to Weiner.
Weiner said the product targets midrange enterprises for use cases such as VMware virtual servers, virtual desktop infrastructure (VDI), and ERP and CRM systems.
Reduxio hasn't released pricing, but said the HX550 will cost around $1 per usable GB assuming a 4-to-1 or 5-to-1 data compression ratio. The system carries a three-year warranty.
Mike Matchett, a senior analyst and consultant at Hopkinton, Mass.-based Taneja Group, Inc., said products that bake in features such as data protection as part of their underlying design instead of as add-on modules have a distinct advantage in the midrange storage market.
"They claim they essentially can roll back to any second in time on any volume, or clone it," he said.
Jeff Kato, a senior analyst at Taneja Group, said he watched a product demonstration and saw the ease with which a user could go back in time to make either a full clone or recovery snapshot. He said users are able to insure the system does not eat up too much space for data protection by tracking the amount of space used for protection and changing the protection policy.
"There are a number of hybrid systems with automatic tiering between flash and disk drives," Jim Miller, a senior storage analyst at Enterprise Management Associates in Boulder, Colorado, wrote in an email. "The real differentiator here is the BackDating feature."
Josh Krischer, founder and principal analyst at Josh Krischer & Associates in Bensheim, Germany, said the Reduxio hybrid storage array could be most beneficial for SMBs that require high levels of data protection and performance, but have limited staff and knowledge.
Reduxio is headquartered in San Bruno, California, and operates a research and development office in Israel. The company secured $27 million through two funding rounds from Seagate Technology, Jerusalem Venture Partners, Carmel Ventures and Intel Capital.
