Today's focus: Probe captures data at high speeds

By Denise Dubie

Network Instruments this week shipped an upgraded probe that the
company says will enable customers to capture data at high
speeds and store it in raw form for use in compliance,
troubleshooting and network forensics.

The company's GigaStor Probe can help IT managers meet
requirements for data retention compliance, capture anomalies
and mine data for troubleshooting purposes. The data mining
capabilities, the company says, could provide network managers
with granular analysis of massive amounts of data.

The GigaStor Probe is typically deployed in a network core near
trunked gigabit links, server farms or VoIP data paths. The new
version captures data at a rate of 250M byte/sec and stores it
to disk. The probe can also monitor up to four full-duplex
gigabit links and can analyze the links either as trunked or
individual ports. The appliance features either a 4T-byte or
8T-byte RAID array to accommodate the storage of data for long
periods of time and comply with regulations.

The GigaStor Probe works in conjunction with Network Instruments
Expert Observer or Observer Suite console software, which is
installed on a desktop or laptop. The probe processes data
locally to prevent the transmission of data to the Observer
management console from slowing down the network. The product
instead sends screen updates to the console to reduce that
network overhead, the company says.

"Monitoring network traffic is not a problem in the regular
realm, but when you get into the gigabit realm, you need to be
able to retain network transactions and capture all the data at
high speeds," says Charles Thompson, manager of sales
engineering for Network Instruments. "The probe can perform
real-time decoding to pinpoint problems and also retain data
over the long term for forensics. We built the probe to make
these tasks easier for network managers."

Network Instruments' GigaStor Probe competes with Network
General InfiniStream products.

Available now, pricing for the GigaStor Probe starts at $35,000
for the 4T-byte probe and $50,000 for the 8T-byte probe. Pricing
starts at about $2,900 for Expert Observer and at $4,000 for the
Observer Suite.
