OES to support mission-critical e-commerce and 
merchandising programs it hosts for its customers – 
including outsourced call centers, private-label Internet 
sites and catalog sales. In addition, OES and CFD 
support the firm’s largest accounts – including a large 
OEM’s repair/replacement materials distribution 
services and a Tier One national carrier’s warranty 
support and accessories program. 
BladeSystem provides consolidation base 
The move to the HP BladeSystem provides TESSCO 
with an ideal virtualization and consolidation platform 
with reduced power requirements, a smaller footprint, 
unified management and flexible configuration. The 
full-size BladeSystem c7000 chassis and c3000 
“shorty” chassis can support both HP Integrity and 
ProLiant blades, multiple operating systems and 
storage blades. 
“We just completed the migration of 20 AlphaServer 
systems and our OpenVMS applications to clustered 
Integrity BL860c blades in three c7000 chassis,” 
Kuff says. TESSCO was also able to transfer some of 
its OpenVMS licensing credits from its AlphaServer 
systems to the new Integrity server blades equipped 
with Intel Itanium processors. “Our licensing cost for 
porting to the Integrity blades was close to zero,” 
Kuff adds. “We also expect to save about one full-
time equivalent in labor and about $200,000 per 
year in reduced total cost of ownership. In addition 
to the AlphaServer systems, our long-term goal is to 
migrate about 100 rack-mounted ProLiant servers to 
the BladeSystem.” 
Kuff’s team has already retired 50 older ProLiant rack 
servers by virtualizing their functions using VMware 
ESX Server on HP ProLiant BL465c and BL495c server 
blades. “You hold one of these HP server blades in 
your hands,” Kuff observes, “then you look at the 10+ 
rack servers that can be consolidated onto it, and you 
don’t need to break out the slide rule to determine 
that it makes good sense.” 
Improved coverage for business continuity
A consolidated technology infrastructure has made 
business-continuity planning far easier as well. “The 
BladeSystem environment offers us disaster-recovery 
options we didn’t have before,” Kuff notes. “Before, 
we had to provide separate AlphaServer and ProLiant 
environments at both our main data center and our 
backup site. Now, we have one, unified architecture 
to support. That makes our lives easier, and saves 
time and money.”  
TESSCO’s XP24000 links via a fiber optic connection 
(2.5 Gbit/s OC-48 fiber) to the firm’s XP10000 at 
the Timonium backup site, about three miles away 
from the Hunt Valley data center. HP StorageWorks 
XP Continuous Access software provides an 
asynchronous replication link between the two 
arrays to provide an up-to-the-minute copy of critical 
data for business continuity and disaster recovery. 
The firm uses the Commvault Simpana Backup 
Solution for its Windows and Linux servers and the 
OpenVMS BACKUP utility to back up OES data to HP 
StorageWorks MSL tape libraries, equipped with HP 
Ultrium drives and cartridges.
“Our competitive advantage stems from our ability 
to provide the highest level of customer service and 
deliver products and solutions on time, every time,” 
explains Kuff. “Our OES and CFD applications must 
be available around the clock, truly 24x7x365. We 
call it responding to the ‘moment of truth’ − when the 
customer is ready to order or needs assistance; we 
have to be ready, without fail.”
“An outage to either our OES or CFD systems could 
mean millions of dollars in lost revenues for us 
and our partners for every day we’re down,” Kuff 
emphasizes, “not to mention the hit we would take to 
our reputation. The 2002 flood hit us Saturday night, 
and by Sunday morning we had OES and our WMS 
application back on line at a backup site Sunday 
morning. That gave us time to move in and recover the 
rest of the data center, which took about a week. We 
learned a lot from that experience, and our business-
continuity preparation is a top consideration.” 
HP Services is part of the plan 
HP Software Consulting Services installed the 
XP24000 in TESSCO’s main data center in Hunt 
Valley, and helped Kuff and his team to a fast start 
“Our licensing cost for porting to the Integrity blades 
was close to zero. We also expect to save about one 
full-time equivalent in labor and about $200,000 per 
year in reduced total cost of ownership. In addition 
to the AlphaServer systems, our long-term goal is to 
migrate about 100 rack-mounted ProLiant servers to 
the BladeSystem.”
