4Blox Unveils 4Mezzo Plus Initiator(TM) to Accelerate iSCSI Initiator Performance

SAN JOSE, CA, Apr 07 (MARKET WIRE) --
4Blox, Inc., dedicated to improving iSCSI performance, today announced
the beta release of 4Mezzo Plus Initiator. This latest software addition
to the 4Mezzo Suite complements the existing target component by lowering
host CPU overhead associated with iSCSI-based storage area networks
(SANs). 4Mezzo offers iSCSI-based SAN storage system vendors a more
flexible approach to reducing the CPU processing demanded by the iSCSI
protocol.

"We are very committed to keeping iSCSI the low-cost SAN protocol of
choice that is also high-performing for demanding environments like
virtualization and 10GbE," said Dan Munro, CEO of 4Blox. "CNICs, RNICs,
TOE -- there is no shortage of expensive hardware acronyms for increasing
iSCSI performance, but 4Mezzo represents the first low-cost software-only
alternative that rivals and exceeds the performance of even the most
expensive hardware alternative."

"4Mezzo Plus is ideally positioned to address the higher CPU overhead
associated with all Virtual Storage Appliances -- which are basically
customized storage targets based on the iSCSI protocol," said George
Crump, president and founder of Storage Switzerland, an IT analyst firm
focused on the storage and virtualization segments.

4Mezzo software components dramatically reduce the CPU overhead in iSCSI
SANs. Unlike expensive hardware solutions, the eco-friendly 4Mezzo
components allow the network connection to handle any type of Ethernet
traffic, at any line speed. The entire 4Mezzo Suite is OS agnostic -- and
4Mezzo Plus (either target and/or initiator) is available in beta on Red
Hat Enterprise Linux.

4Mezzo OS-level components sit directly between the iSCSI protocol and the
TCP protocol. This critical location is where overall iSCSI performance is
often determined. These components use patent pending techniques to
dramatically reduce the CPU overhead associated with the block read and
write software in existing SAN equipment targets and OS platform
initiators.
