DSI releases new network storage protocol into Open Source

Patrick Khoo writes: The Data Storage Institute (DSI) today released the HyperSCSI
protocol and reference implementation code into open source. HyperSCSI is a new storage protocol
designed for the transfer of SCSI data and commands over networks. The current protocol release runs on
Ethernet-based networks.

"Our engineers' work on HyperSCSI demonstrates that using Ethernet for high performance storage
networking is indeed viable and secure," said Professor Chong Tow Chong, Director for DSI. "HyperSCSI is
designed to be extremely flexible. In this way, it can meet the network storage needs of various diverse
technology fields, from consumer electronics to enterprise storage systems."

DSI, a research institute of the Agency for Science, Technology and Research (A*STAR), has been
working on the HyperSCSI project for over two years. Unlike other network storage protocols based on
Ethernet, HyperSCSI does not use TCP/IP as a foundation for communications. While this may run counter
to convention, it has in fact allowed HyperSCSI to achieve high throughput without the need for complex
and expensive hardware add-ons. Intrinsic advantages of bypassing TCP/IP include immunity to hacking via
the Internet, simplicity and plug-and-play functions, making HyperSCSI easy to use for developers and

Benchmarks conducted by the DSI using common off-the-shelf hardware demonstrate that HyperSCSI can
achieve 100MB/s sustained data throughput using a 2GB size data set. There was no requirement for
customized hardware, device drivers, accelerator chips or proprietary software. In another
demonstration, HyperSCSI was used to display smooth DVD video played directly from a standard DVD drive
over an 802.11b Wireless LAN network.

Not limiting itself to just IDE and SCSI hard disk drives, HyperSCSI also supports optical, tape and
even removable USB drives. DSI has successfully used HyperSCSI for CDRW recording and tape drive backup
over the network. It is compatible with Fast Ethernet, Gigabit Ethernet (with and without Jumbo frames)
and 802.11b Wireless LAN. The present version of HyperSCSI also includes built-in 128-bit encryption.

Some of the application areas in which HyperSCSI is currently being tested include data backup and
recovery, storage for high performance computing clusters and grids, wireless network storage, home
network storage, personal area network storage and Ethernet-based storage area networks.

Upcoming developments for HyperSCSI include multi-channel support, in-band management and wider
platform support. Ultimately, HyperSCSI will help to provide cheaper and more efficient storage
solutions to both enterprises and ordinary consumers.

The HyperSCSI protocol has been recognised by the Institute of Electrical and Electronics Engineers
(IEEE) and assigned the Ethertype Number #889a.
