NEW YORK -- The InfiniBand Trade Association (IBTA)
a global organization dedicated to maintaining and enhancing the
InfiniBand architecture, has announced the release of a new capability,
bringing the power of the Remote Direct Memory Access (RDMA) I/O
architecture to Ethernet-based business solutions.
The new specification is called RDMA over Converged Ethernet (RoCE),
pronounced "Rocky." Products based on RoCE will reach the market during
the coming year, IBTA officials said.
IBTA announced the news at the 2010 High Performance Computing Linux Financial Markets
show and conference here on April 19.
RoCE, built on a foundation of the highly efficient use of computing
resources, brings significant benefits to end users, IBTA officials
said. By reducing the number of servers needed, eliminating cabling and
improving application performance, RoCE can produce energy savings and
reduce the footprint of Ethernet-based data centers. Its unique "one
fat pipe" approach to server I/O gives the user great flexibility in
deploying applications and is an excellent complement to virtualization
strategies being deployed today. By attacking latency, RoCE increases
performance in search, database, financial and high transaction rate
"RoCE addresses a key concern of the enterprise - maximizing and
protecting current investments in IT," said Cindy Borovick, research
vice president, Datacenter Networks at IDC, in a statement. "RoCE
leverages field-proven RDMA, ubiquitous Ethernet and fabric management
solutions. This will benefit data center network end users by
consolidating data, storage and clustered networking and reducing
"The new RoCE specification, with a purpose-built and proven RDMA
transport, provides the most efficient and lightweight transport over
Layer 2 Ethernet," said Asaf Somekh, vice president of marketing at
Voltaire and member of the IBTA Steering Committee, in a statement.
"RoCE is expected to enable the enterprise data center to serve more
clients with a broader range of applications - all while providing
faster response times and reducing the number of servers, cables and
RDMA and low latency clustering has dominated the high performance
computing space, IBTA said. For data center and cloud environments,
RDMA is enjoying increasing adoption in business solutions such as data
warehousing, financial services and transaction processing. Low latency
and RDMA capabilities in data center fabrics enable end-users to
achieve significantly higher and deterministic transaction rates while
increasing the efficiency of clustered servers and storage systems and
reducing energy consumption - resulting in significant
return-on-investment (ROI) benefits.
RoCE is implemented and downloadable today in the OpenFabrics
Enterprise Distribution (OFED) 1.5.1. Many Linux distributions, which
include OFED, support a wide and rich range of middleware and
application solutions such as inter-process communications (IPC),
sockets, messaging, virtualization, storage area network (SAN), network
attached storage (NAS), file systems and databases. RoCE can therefore
deliver all three dimensions of unified networking on Ethernet - IPC,
NAS and SAN, IBTA said.
