and Reno, Nevada. TESSCO’s custom-built Order 
Entry System (OES) and Configuration, Fulfillment 
and Distribution (CFD) application based on INFOR’s 
WMS system are the heart of the firm’s operations 
and support customer orders taken by phone, e-mail 
and through web sites such as TESSCO.com. 
Strong growth signals need for change
TESSCO has experienced strong, steady growth 
in recent years. This growth, in combination with 
changes in its mix of customers and products/services, 
has led to increased pressure to migrate the mission-
critical OES application from a legacy AlphaServer 
platform to a new, consolidated enterprise 
infrastructure. 
“As soon as HP certified OpenVMS for its Integrity 
server blades, we began making plans to migrate 
OES,” notes TESSCO’s Vice President of Technology 
Development Services Hal Kuff. However, with the 
firm’s data demands growing at 25 percent each 
year, TESSCO first looked to reinforce its storage 
infrastructure before tackling the servers that were 
powering its mission-critical applications. 
The firm relied for years on two mirrored HP 
Enterprise Virtual Array (EVA) systems at its main 
data center in Hunt Valley, and a third EVA at its 
Reno distribution center. The plan was to replace the 
two EVAs in Hunt Valley with a single, larger storage 
array.  
“TESSCO is dedicated to HP infrastructure – our 
data center is like an HP lab,” Kuff says. “However, 
we still explore every option when it comes to major 
technology upgrades. We looked at HP, EMC, 
Hitachi and NetApp systems. We have had an HP 
StorageWorks XP10000 at our Timonium, Maryland 
backup site for about 18 months, and it is an 
extraordinary machine. So, the leap from the EVA to 
a larger XP system was our thought from the outset.”
Above all, Kuff and his team demanded a system 
that would provide total reliability. “We have 
been StorageWorks fans for more than 20 years,” 
Kuff explains. “We learned just how rugged HP 
StorageWorks systems are when our primary data 
center was flooded in December 2002. An eight-
inch water main broke and flooded the data center, 
blasting our storage arrays across the room. Out of 
500 hard drives, we lost only two; but none of our 
data was lost.” 
After carefully considering all his alternatives, Kuff 
chose the HP StorageWorks XP24000 array to be 
the mainstay of TESSCO’s enterprise environment: 
“We liked the fact that the XP24000 doesn’t require 
a lot management oversight, and really liked that we 
can fine tune the system to optimize it for our critical 
applications − to create our own throughput models. 
We are able to leverage our experience with the 
XP10000. It was also critical that the XP24000 is built 
to survive just about anything. We know it’s not going 
down.”
Servers get the next call
After dealing with TESSCO’s storage needs, Kuff and 
his team next moved to upgrade and consolidate 
the multi-platform infrastructure the firm has relied 
on for many years: Microsoft® Windows®, Linux 
and OpenVMS AlphaServer systems. “We were 
very satisfied in the reliability and performance 
of our HP ProLiant and AlphaServer systems, but 
felt that we could gain both improved operational 
efficiencies and strengthen our business continuity 
position by consolidating to one architecture − the HP 
BladeSystem.” 
TESSCO is a long-time HP customer, and the OES 
application was originally developed and has 
run for more than two decades on AlphaServer 
systems under OpenVMS. The firm’s CFD application 
runs under Windows on HP ProLiant servers. Both 
applications depend on multiple HP ProLiant Linux 
server clusters running Oracle® 10g databases.  
Other important enterprise applications, including 
Microsoft Exchange Server and Oracle Financials, 
run on ProLiant rack and server blade systems 
under Microsoft Windows and Linux. The desire 
to migrate the OES application was tempered by 
the risks associated with any migration. These risks 
were heightened due to TESSCO’s reliance on 
“We have been StorageWorks fans for more than 20 
years. We learned just how rugged HP StorageWorks 
systems are when our primary data center was 
flooded in December 2002. An eight-inch water 
main broke and flooded the data center, blasting our 
storage arrays across the room. Out of 500 hard 
drives, we lost only two; but none of our data was 
lost.”
