Virtual Instruments improves SAN monitoring probe, software

Wednesday, September 7th, 2011

Virtual Instruments Inc. currently upgraded a SAN monitoring products with a new SAN Performance Probe and updated
VirtualWisdom software. Both products can yield prominence in a Fibre Channel (FC) SAN and assistance administrators investigate and troubleshoot
performance problems.

The SAN Performance Probe, that replaces a SanInsight Probe FCX, is an out-of-band 2U
monitoring apparatus that gets real-time information from Fibre Channel (FC) headers. The new device has
205 metrics, compared to 108 in a prior version. Administrators can use these metrics to gain
a granular perspective of how a I/O trade is relocating in a FC SAN. The examine now also supports 8 Gbps FC compared to a prior chronicle that upheld 4 Gbps. Virtual
Instruments executives pronounced they devise support for 16 Gbps FC and Fibre Channel over Ethernet (FCoE) in destiny versions.

The SanInsight Probe FCX product was grown during Finisar Corp. before Virtual Instruments spun
out of that association in 2008. The SAN Performance Probe is a initial product totally developed
since a spin-off.

“The marketplace told us it was time for a next-generation probe,” pronounced Skip Bacon, CTO for Virtual

“It’s a new box, built from a belligerent adult to reinstate a FCX that came from Finisar,” pronounced Eric
Slack, comparison researcher during Storage Switzerland. “The examine has 8 channels, monitoring eight
separate FC links during a same time. The hardware examine sits on a network and samples Fibre Channel
frames that go past a probe. Nobody does that in a Fibre Channel world.”

The SAN Performance Probe connects to a Windows-based server on a backend and Virtual
Instrument’s SANInsight Traffic Access Point (TAP) on a front end. The TAP device, that acts
like a vigilance splitter, sits between a FC switches and storage arrays. The SAN Performance Probe gets real-time
monitoring information from a FC support headers. The headers enclose metadata, including source
destination, routing, review and writes, and information latency from a I/O traffic.

Bacon pronounced a metric gaining a many seductiveness is a buffer-to-buffer credits. When a device
logs onto a switch, a dual inclination determine on how many credits are available. Any time trade is
sent, it has to be accompanied by a credit. A brown-out can start or opening can stop if the
credits are delayed to pierce or they are not exchanged. “We can tell we if a credit is delayed or if the
device ran out of credits,” Bacon said. “We have several metrics that lane a state of the

The company’s VirtualWisdom runs on dual other probes, that like a SAN Performance Probe have
been rebranded. The Virtual Server Probe, before called a Virtual Wisdom ProbeVM, resides on
a Windows-based server and gathers opening information from VMware vCenter APIs. The SAN Availability
Probe software, before called a ProbeV, also resides on a server and pulls SNMP information from FC
switches so IT administrators can get Storage Resource Management (SRM) data.

 “We’ve renamed a products so they make sense,” Virtual Instruments CEO John Thompson

The VirtualWisdom 3.0 core program is embedded with a SQL database that has been upgraded to hoop a additional series of metrics
being processed. It also has been extended so administrators get a improved perspective of a complex
virtual fabric, quite of all a relations between a practical and earthy ports.
Automated fabric discovery, a new topology navigation and hunt capability have been added. “Now
in a UI, we make it easier to see ports for slackening and diagnostics,” Bacon said.

Virtual Instruments also hired George Harrington, before of IBM Corp., BMC Software Inc. and
Symantec Corp., as arch financial officer as a association prepares to go public. “We would like to
do an IPO,” pronounced Thompson.

Thompson, a former Symantec Corp. CEO who took over during Virtual Instruments in May 2010, said
the businessman has 100 business and he expects to be essential in 15 to 18 months. Thompson first
joined Virtual Instruments as an financier and house member in 2009.  He also served on the
National Infrastructure Advisory Committee (NIAC), creation recommendations per confidence of U.S
infrastructure, underneath a President George W. Bush administration.
