Consolidate Workloads with Server
Virtualization
VMware Infrastructure 3
Our organization had several
IT needs that couldn’t easily
be addressed with our current
budget and infrastructure, so we
began looking at VMware virtualization
products a few years ago. VMware
Workstation was introduced into our
environment by our systems team first,
and that was quickly followed up with a
GSX server evaluation. All of that led up
to our current IT infrastructure, which is
now based on the VMware Infrastructure
3 (VI3) platform.
We had several needs that VI3 seemed to be the solution for: the
need for customized development environments; new product rollouts
that consisted of small numbers of low-utilization servers; ways
to address our data center capacity, cooling and power concerns; and
the need to significantly reduce costs associated with upcoming server
replacements. Getting VI3 up and running was a relatively painless process:
our internal system engineers were able to put our first two-node
ESX cluster into production in a matter of days.
Since we began using VI3, we’ve been able to realize a number of
specific benefits. We’ve been able to reduce our server pool using server
consolidation, often at a fifteen to one ratio. Our server deployment
time went from days or weeks to minutes and hours, thus reducing
the overall development cycle of new products and application. We’ve also experienced zero cost hardware replacements—when equipment
begins to fails we perform physical to virtual server conversions. We’ve
also used VI3 to take snapshots of mission critical servers to enable
recovery from failures, and we’re also in the process of converting to a
virtual QA Infrastructure. Our goal is to have one-to-one representation
of all mission critical applications for QA and testing. Finally, our developers
and application used to maintain multiple physical workstations:
one for production, one for development, and one for QA. We’ve been
able to consolidate all three of those functions onto one physical PC
using VMware Workstation.
We’ve had relatively few issues with VMware during our first 18
months of use. I attribute this to the fact that we opted to wait for the
VI3 release as opposed to deploying 2.5x. All of our VMware products
are purchased through HP, and we’ve found HP’s virtualization support
to be excellent.
There are some things I would like to see VMware improve upon,
ranging from improvements to the physical to virtual (and potentially
virtual to physical) conversion processes. I’d like to see more VI3 integration
with other enterprise products, and Storage V Motion [in ESX
3.5] would be a nice addition. I’d also like to see VMware reduce their
licensing costs. All that said, we’ve realized substantial costs savings by
switching to VMware VI3.

Exchange e-Discovery and Email Recovery
Lucid8 DigiScope 1.1
In our IT environment, users wanted
to have the ability to restore the
contents of a single folder or e-mail
within Microsoft Exchange. Another
requested feature was an ability to
examine the contents of a specific mail
folder without requiring the user to log
on to the network as a specific user. I
started doing some research on possible
solutions, and I came across DigiScope
from Lucid8. I visit the Lucid8 Web site
fairly often, since I’m also currently using Lucid8’s DigiVault and Go
Exchange products.
Installation was straightforward: I had DigiScope up and running in
less than an hour, and I didn’t need to reboot or take Exchange off-line
to complete the installation. When I did need support during the install
process, Lucid8 was very efficient at resolving technical issues quickly.
Using WebEx [remote] access, they can log into your system and walk
you through the setup process while sharing the desktop. I found the
support staff to be very friendly and knowledgeable.
Lucid8 tech support has been good, but the online help manual for
DigiScope is very basic: I believe it could have included more extensive
and detailed information about how the product functions. I think most
of the users of DigiScope are fairly tech savvy, so more information
would have been welcome.
Some of my favorite DigiScope features include a user-friendly,
Windows Explorer-like GUI; the ability to export emails and folders to
multiple formats (i.e., .PST, .MSG, and .XML); and performance adjustment
tools that allows you to set the level of CPU / computer resources.
I also like how well DigiScope seamlessly integrated with Exchange and
Active Directory.
On the first day I used DigiScope, it saved me several hours of time
by helping me restore some deleted mail folders. I’ve previously used
external consultants to help me with very complex Exchange issues, such as restoring databases. With DigiScope, those calls are now a thing
of the past— and so is the extra cost in maintenance.
After using the software over the past 11 months, I’d be happy to recommend
Lucid8 to other IT pros—especially if you’re using Exchange
and want to save on maintenance costs. Companies that rely on outside
support and consultants for their Exchange upkeep can save a lot of
money by using DigiScope. In my experience, using DigiScope has paid
for itself by eliminating our need for external Exchange help.

Defragment and Optimize Hard Disks
Diskeeper 2008
I work for a PBS television station
with millions of viewers throughout
the United States and Canada. Our
workflow relies upon working computer
equipment. We don’t use hammers,
drills or ovens to fulfill our business
objectives—we use computers, which
are prone to having their hard drives
getting defragmented over time, which
contributes to poor system performance.
You wouldn’t use dull knives or blades if
you were a butcher, or a broken hammer if you were roofer, or even a dull
pencil if you were an architect. Why would we use less than fully functional
computers? The built-in defragmentation utility in Windows didn’t fill my
needs at all, so we became a true multi- user corporate license holder for
Diskeeper in 1999. We’ve upgraded to newer versions of Diskeeper over
the years, including the latest release: Diskeeper 2008.
Five versions of the software are offered for businesses, including
Professional, Professional Premier, Server, Enterprise Server, and
Administrator. All versions (but Professional) include I-FAAST (Intelligent File Access Acceleration Sequencing Technology), a feature
that helps accelerate the programs you use most frequently through
a special defrag mode that puts those commonly used in files and
libraries in a specific location on the hard drive that speeds disk access
substantially. Other nice features include an automatic real-time
defragmentation feature (that defrags in the background while you
work), and a FragShield function that keeps your hard drive’s MFT
(Master File Table) and paging file automatically defragged.
As for things I would improve about the software, I would like to see
more companies go with a ‘buy one license and use it on three PC’s’
mode of licensing. It would be nice if Diskeeper Corporation followed
this model.
I’ve seen the boot time defrag on Diskeeper 2007 not work on some
computers using external Firewire drives or USB drives, and this problem
likely exists in Diskeeper 2008. I’ve found that the root cause for this problem
isn’t Diskeeper: Certain motherboards do not support USB drives or
Firewire drives until Windows XP boots to a certain point. This is a hardware
issue, so potential users of Diskeeper should check their motherboard
BIOS if they’re having trouble with the defrag-on-boot option.
