Founded in 1908, New England Law|Boston
(NEL|B) needed a top-to-bottom upgrade of its aging
technology infrastructure as the school approached
its centennial – and had to accomplish that task
within the limits on space, power and cooling of the
institution’s compact location in downtown Boston. Top
priority was its outdated Novell e-mail system, which
broke down regularly.

broke down regularly.
Explains Director of IT Nathan Reisdorff , “Because
of the need for a paper trail of documents, for a law
school, e-mail is even more critical than telephones.
Our professors are working lawyers, and NEL|B runs
a free legal clinic that focuses on domestic abuse
cases. Students and faculty are working, often pro
bono, with real clients, on real cases. And if e-mail is
down, we might miss a court date, for example, with
real-world consequences. In addition, almost all law
school student recruitment, admissions, and career
services are implemented using the Internet; so if our
web site is down, we may lose a potential student or
a job opportunity for a graduate.”

The verdict is in: Blades and virtualization
Working with HP Gold Reseller partner Worldcom
Exchange Inc. (WEI), NEL installed Microsoft
Exchange Server 2007 e-mail running on HP server
blades. The school uses a BladeSystem c7000
enclosure, populated with three HP ProLiant BL685c
server blades with AMD Opteron™ 64-bit processors
and five HP ProLiant BL480c server blades with Intel®
Xeon™ 32-bit processors.

“We wanted 64-bit processors for specific
applications to give us better performance,” says
Reisdorff. “For instance, we run our Microsoft
Windows® Active Directory Server on a 64-bit
server blade. On the other two we loaded VMware
Infrastructure 3 and the Exchange environment
on seven virtual servers, giving us load balancing
and redundancy. We also have VMware loaded
on an HP ProLiant DL380 server as backup for the
BladeSystem.”

High availability is the law at NEL
System storage is on an HP StorageWorks Enterprise
Virtual Array (EVA), with a StorageWorks MSL4048
tape library for backup. For fast disaster recovery, HP
StorageWorks Storage Mirroring Software replicates
data from the EVA to a disk array in another building.

NEL worked with HP and WEI to make sure the
new system met the school’s No. 1 priority: highly
available e-mail for 1,200 students and 150 staff
members. “The new system is up 24x7,” says
Reisdorff. “The BladeSystem c7000 has redundant
power supplies, fans and I/O. We load balance
across two servers, and if one goes down we can
switch to the other.”

With a virtualized infrastructure, Exchange and
other applications share servers and storage
resources, maintaining a high level of utilization while
decreasing costs associated with underutilization and
over-provisioning. Plus, if there is a problem with a
virtual server, the application just gets reassigned to
another virtual server and keeps running.

Virtual servers let the NEL technology team do
maintenance without interrupting service. Reisdorff
explains, “To upgrade an application on a virtual
server, we just copy the application to another virtual
server, where it keeps running as usual. When the
upgrade is tested and ready we cut it back over.”

Virtualization also gives NEL the tools to recover
quickly after an accident or a virus attack. “VMware
takes snapshots of each machine periodically,” says
Reisdorff. “If there is damage to a machine, we
can go back to an earlier clean version. We also
do snapshots of the SAN, using HP StorageWorks
Storage Mirroring software, so we can go back and
restore the SAN to an earlier point.”

“HP is a company that is always improving its
products, rather than just commoditizing them. They
have the whole infrastructure, all tested together, all
under the same name, and it all works together and
communicates together. And when we talked to other
customers about service, the best recommendations
we got were for HP.”
