HOW WILL YOU HANDLE YOUR GROWING NETWORK LOAD?

InfiniBand, EtherFabric and iWarp are all high-speed
interconnect technologies aimed at offloading network
connections from server CPUs. And the buzz on them is picking up
as users look for alternatives to 10G Ethernet to handle their
growing network loads. What questions should you ask about these
new technologies? For more, click here:

WAN acceleration gear grows up

By Tim Greene

Businesses should expect to face a wide and confusing array of
choices when seeking the right WAN acceleration gear to make
transaction times tolerable as they shift from branch office
servers to centralized server farms.

Centralization reduces the number of servers and so saves
capital and maintenance costs, and improves security. But it
also means more end users access data via the WAN - users who
will scream if performance degrades as a result.

Availl, Cisco and Brocade offer products tuned to speed up
specific types of WAN traffic - wide-area file services or WAFS
- which represent a large chunk of the new WAN traffic that
results when servers are centralized. But a throng of other
vendors says its more broadly focused gear is better suited to
real customer needs. All WAN traffic can benefit from
acceleration, they say, and not all WAN traffic is WAFS.

This more broadly focused equipment can boost the performance of
a range of network traffic, not just WAFS, although some vendors
are tuning their gear so it gives special treatment to WAFS, as
well. These WAN-acceleration vendors include Array Networks,
Converged Access, Expand, Juniper, Orbital Data, Packeteer,
Riverbed Technology, Silver Peak Systems, Swan Labs and others.

As an example of this tweaking for WAFS, Packeteer this week is
announcing a software download for its PacketShaper appliances
that can target priority treatment for Microsoft Windows Server
2003 R2, as well as Active Directory, Exchange and distributed
component object model traffic. Packeteer also is teaming with
Tacit Networks to provide a separate Tacit appliance that caches
data in branch offices as a way to speed WAN transactions.
