The Business Case for Adopting Blade Systems in the Data Center

HP ProLiant Blade Systems: The Business Case for Adopting Blade
Systems in the Data Center. When making a purchase decision,
blades should be considered as an integrated, consolidated
infrastructure-or a complete system-that includes servers,
storage, networking and power. Learn how HP's blade system
represents a new approach to infrastructure that can accelerate
the integration and transformation of your data center.

FOCUS ON RECOVERY

IT professionals are changing the way they back up and recover
data, experts say, with new emphasis on the speedier fetching of
data made possible by advancing technologies. At a recent
storage conference in Orlando, disk-based backup solutions were
touted - find out if attendees agreed and if faster storage
solutions will soon be available. Click here:

Today's focus: Myricom goes 10 Gig

By Deni Connor

Clustering vendor Myricom last week joined the ranks of Ethernet
faithful by adopting 10 Gigabit Ethernet for use in its switches
and network adapters.

The new Myri-10G switch will feature both Myrinet's Ethernet
emulation and 10 Gigabit Ethernet. Each switch, which has from
16 to 128 ports, will cost as little as $400 per port. The
network adapters can work with either Myricom switches or
standard Ethernet switches.

Myricom has always used "Ethernet emulation." In Ethernet
emulation, Ethernet packets are encapsulated as Myrinet packets
with a type "Ethernet." Ethernet emulation can carry any packet
traffic and protocol, including TCP/IP, that can be carried on
an Ethernet network.

Myricom claims that Ethernet emulation allows a higher data rate
and lower latency than native Ethernet.

In adopting native Ethernet for its switches - technically the
Ethernet emulation protocol is converted to native Ethernet -
the company is appeasing commercial organizations that have
settled on Ethernet as their protocol of choice.
High-performance computing environments may choose to stay with
Ethernet emulation because protocol conversion does introduce a
couple milliseconds of latency.

Myricom's network adapters interact directly with application
protocols and handle network protocols without affecting the
host operating system or CPU. Its switches use cut-through
routing, which steers packets according to routing instructions
at the head of the packets. They also use source routing, which
is determined by the source adapter, rather than destination
routing used by Ethernet switches.

The Myri-10G network adapters will be available in September for
$795. The switches are also expected to be available in
September, starting at $6,400 for a 16-port switch.
