StoneFly Introduces RAIDML for Extreme Protection of Mission-Critical Files and Applications on IP SANs

HAYWARD, CA, Nov 23 (MARKET WIRE) --
StoneFly(TM), Inc., a leading supplier of integrated IP storage area
network (SAN) systems, today unveiled StoneFly RAIDML(TM), a new
multi-level (ML) approach to data protection for IP SANs. RAIDML goes
beyond conventional No Single Point of Failure (NSPOF) configurations to
provide the highest levels of data protection for mission-critical files
and applications, along with general file storage.

Now available as an integrated part of StoneFly's Voyager HA IP SAN,
RAIDML offers the ability to create NSPOF volumes as well as purely RAID
5 or 6 protected volumes -- all in a single storage unit or aggregated
across multiple storage units. The creation of different RAID sets in
this manner allows administrators to achieve multi-level data protection
without increasing costs and without the need for doubling drives to meet
NSPOF requirements.

An Economical Alternative to Conventional NSPOF Approaches

According to BJ Jalali, director of product management for StoneFly, there
are several conventional ways to attain NSPOF on storage volumes:
mirroring (RAID 1); mirroring and striping (RAID 10 or 0+1); complete
subsystem mirroring (RAID 51 or RAID 61); or host-based applications that
manage mirroring.

"Today's storage devices have gone a long way toward protecting data
through the use of different RAID levels," Jalali says. "However, to date,
all conventional NSPOF configurations require 100 percent duplication of
actual disk storage, leaving the customer with little choice but to spend
more while adding complexity to the data center. StoneFly is very pleased
to offer RAIDML as an economical and effective alternative."

Implemented in StoneFly's Active-Active Controller Architecture

RAIDML is implemented in StoneFly's active-active controller architecture,
protecting both NSPOF and traditional RAID sets with comprehensive auto
fail-over and fail-back capabilities. RAIDML is supported by the StoneFly
StoneFusion(TM) operating system, which equips StoneFly IP SANs with a
patented storage virtualization engine; StoneFly Reflection(TM) for local
and campus mirroring; StoneFly Snapshot(TM) for fast, efficient data
recovery; and advanced features such as Quick Sync to further enhance data
protection.

Quick Sync allows customers to rapidly restore RAIDML or mirrored iSCSI
volumes in the event of a storage path or site failure. With StoneFusion
keeping track of block-level changes to the operational volumes, as system
restores occur Quick Sync updates the RAIDML and mirrored volumes quickly
by only restoring net changes, thereby bringing the volumes back online
immediately -- without the time and hassle of an entire restore operation.
