“ With the Riverbed Steelhead appliances in place, replication takes just one hour. This enables us to hit our backup windows for business continuity and DR.” Rich Raether, Manager, Network Engineering, Quarles & Brady
At the law firm Quarles & Brady LLP,
Rich Raether had recently taken over as
manager of network engineering. Based
in Milwaukee, Wisconsin, Quarles & Brady
began as a local firm 118 years ago and
has grown to earn a place among the
Am Law 200, with approximately 450
attorneys and offices in Chicago, Illinois,
Madison and Milwaukee, Wisconsin,
Phoenix and Tucson, Arizona, Shanghai,
China—and Tampa and Naples, Florida.
When Wilma struck Florida, the office in
Tampa wasn’t open yet, but the Naples
office needed to prepare for the storm.
The office had direct-attached storage,
common for Quarles & Brady’s remote
offices. The storage backed up to tape
which was stored in safety-deposit boxes.
The disaster recovery plan was sending
the last night’s tapes by overnight express
to Milwaukee headquarters.
Shut down by a hurricane
The Naples office was closed for four days.
Attorneys went to hotel rooms in Atlanta
or went to Milwaukee to work, but their
data was inaccessible during that time,
which hampered their work.
That made an impression on Raether,
who had arrived at Quarles & Brady as the
firm was refreshing its IT infrastructure
with new servers, networking equipment
and storage. In the process of rebuilding,
Raether was looking for new hardware
solutions for the company’s remote
offices that would enable the firm to avoid
a repeat of the Hurricane Wilma incident.
Most of Raether’s staff of 15 worked in
the firm’s main data centers in Milwaukee
and Phoenix. The smaller offices use
local office IT support contractors, not
engineers. “If we had a problem, we
had to get on the phone with them and
talk them through the process,” says
Raether. “We were virtualizing some of the
servers in these locations with VMware
to simplify management, and we were
looking at getting new storage to replace
the direct-attached storage and provide
some disaster recovery capability. As it
turned out, what really drove that was the
Naples office and Hurricane Wilma. We
didn’t want to be putting tapes in safety-
deposit boxes and overnighting the tapes
to Milwaukee in the face of a hurricane.
We wanted to make the data safe so that
attorneys could continue to work from
wherever they were.”
Simplified storage with built-in replication
The team looked at Fibre Channel storage
options and decided that a traditional
frame-based SAN would add management
requirements, not simplify them. They then
evaluated virtualized iSCSI SAN solutions
from LeftHand Networks, NetApp and Dell
EqualLogic. “We wanted easy-to-manage
storage that would give us the ability to
set up a disaster recovery scenario,” says
Raether. “Dell EqualLogic was the only
solution that offered both, with replication
features built-in at no additional cost.”
On Monday, October 24, 2005, Hurricane Wilma made landfall in Florida. It was the most intense hurricane ever recorded in the Atlantic basin, and the fourth most costly storm in U.S. history. Damage in Florida alone totaled more than $26 billion. In some areas, power was out for two weeks.
Technology at Work
Hardware
Dell™ EqualLogic™ PS6010XVS, PS6000XVS, PS6000S, PS5000, PS100 iSCSI SANs
Dell PowerEdge™ M610 blade servers with Intel® Xeon® processors 5600 series
Dell PowerEdge M1000e modular blade enclosure
Dell PowerEdge R710 servers with Intel Xeon processors 5500 series
Intelligent management of virtual desktop workloads
The firm is using Dell EqualLogic
PS6010XVS SANs for its virtual desktop
initiative with Citrix XenDesktop, currently
underway, which will provide attorneys
with the ability to log onto their Windows-
based workstations remotely. The
PS6010XVS is a 10 Gigabit Ethernet hybrid
array with both solid-state drives (SSD) and
serial-attached SCSI (SAS) drives in a single
enclosure, with the ability to automatically
load balance between the two storage
tiers. “We’ve reduced the time it takes to
provision a virtual desktop from 7 minutes
to around 40 seconds with the Dell
EqualLogic PS6010XVS,” Raether notes.
Unlike most other workloads, virtual
desktop workloads are highly variable
in terms of input/output operations per
second (IOPS) requirements. Typically
there are periods of very high IOPS when
many users are accessing the storage,
followed by periods of lower usage. For
example, every morning when a large
number of users are logging in to their
desktops—called a “storm”—there is
a very high demand for IOPS on the
storage infrastructure that supports the
virtual desktops. While it is possible to
design the storage to support these peak
performance needs by overprovisioning,
that creates cost-inefficiencies.
Dell EqualLogic hybrid arrays are designed
to handle such a variable workload without
having to overprovision. The PS6010XVS
arrays automatically move hot data to
SSD drives, which are capable of handling
much higher IOPS than SAS or SATA
drives. After the login and boot storms are
over, the PS6010XVS arrays migrate the
workload to SAS drives automatically.
“We’re seeing amazing performance
results for virtual desktops with the hybrid
EqualLogic arrays,” says Raether. “The
heavy disk workloads hit the SSD drives
automatically and remain there as long as
necessary to ensure optimal performance.
Provisioning disks, boot times and overall
end user environment responsiveness
have improved greatly.”
1.8-fold faster discovery process
Quarles & Brady virtualized most of its
Microsoft SQL Server 2008 database
environments using Dell EqualLogic
PS6000XV SANs with 15K SAS drives.
“We also have a couple of Dell EqualLogic
PS6000S arrays with SSDs in two different
storage pools,” says Raether. “We keep
the databases themselves on SAS drives
and the logs and temp databases on
SSDs. The SSDs give us 1.8 times the
performance—almost double.”
The performance boost enables the
firm to perform processes such as
discovery in almost half the time it
took in the previous Fibre Channel
SAN environment, saving clients billable
time and improving productivity.
10-fold faster replication time
To optimize WAN traffic and provide
fast access to documents without
maintaining a local document
management infrastructure at each site,
Quarles & Brady uses Riverbed Steelhead
appliances at all its offices. Because the
appliances deduplicate data and increase
the efficiency of the TCP connection, data
can traverse the WAN much faster, making
the WAN feel very much like a LAN.
Powered by the Riverbed Optimization
System (RiOS), the Steelhead appliances
enhance the benefits of EqualLogic
replication by decreasing replication
time 10-fold. “Replicating a volume
from Chicago to Milwaukee without
the Steelhead appliances might take 10
hours,” says Raether. “With the Riverbed
Steelhead appliances in place, replication
takes just one hour. This enables us to
hit our backup windows for business
continuity and DR, because as we’re
replicating larger and larger volumes
across the wire, at some point those
replication jobs would be running into
the morning hours without the Steelhead
appliances. We’ve also reduced our
courier bills with the ability to quickly
send large files across the WAN.”
“ The data center was built to last 10 years, but I anticipate that it will last us 15 years with the Dell EqualLogic storage and the Dell PowerEdge servers, extending the value of our investment by 33 percent. It’s rare that IT equipment can have an impact like that.” Rich Raether, Manager, Network Engineering, Quarles & Brady
