Reduce Fire Safety Risk in Your Network!

Concerns are rising about the growing number of combustible
cables present in buildings required to service the
ever-increasing demands of IT networks. More workstations are
taxing the infrastructure. These concerns are the thrust behind
new "limited combustible" cables that reduce fire safety risk.

CAN'T STAND THE HEAT?

Neither can your servers. Having dense servers means more heat
and more power consumption in smaller spaces. Find out why just
adding more air conditioners won't cut it and what you need to
do to stay cool this summer... and beyond. Click here:

Today's focus: TCP Offload lifts 10G Ethernet over other
technologies

By Jeff Caruso

Chelsio Communications this week is crowing over the fact that
The Ohio State University found that its 10 Gigabit Ethernet
network interface card outperforms InfiniBand and Myrinet in
server cluster environments.

Chelsio uses TCP Offload to increase performance. Its TCP
Offload Engine handles the TCP protocol stack in hardware so
that the host server or workstation doesn't have to do so. This
frees up the host CPU to do other tasks, and the machine should
be able to use more of the bandwidth available to it.

D. K. Panda, professor of Computer Science and Engineering at
Ohio State, compared Chelsio's technology to InfiniBand and
Myrinet.

Chelsio quotes him as saying, "Although significant research has
been performed on the individual technologies, no work had been
done to compare the capabilities of these technologies in a
homogenous environment. For high-performance computing
environments where TCP/IP is dominant (such as legacy scientific
applications, grid-based or heterogeneous-computing
applications, file and storage systems, and other commercial
applications), 10 Gigabit Ethernet with [the TCP Offload Engine]
is the only high-performance solution, and Chelsio is the only
vendor offering this solution today."

Meanwhile, Los Alamos National Laboratory confirmed that 10
Gigabit Ethernet with the TCP Offload is faster than 10 Gigabit
Ethernet alone. The researchers there say that, compared to
ordinary 10 Gigabit, Chelsio's technology improved throughput by
50% to 100%, increased the transaction rate by an order of
magnitude on heavily loaded Web servers, and used 40% fewer CPU
cycles.

Interestingly, the researchers say that the improvements in CPU
utilization obviate the need for jumbo frames.

THE ROI OF VOIP

When it comes to VoIP, most network managers are satisfied that
the technology works. But there are questions: What will the new
technology cost to roll out and support, and what benefits can
companies expect to reap? Check out NW's step-by-step guide on
how to determine the true cost and benefits of VoIP. Click here:
