Saving money, space and energy with blade virtualisation

How a Rhode Island law firm is doing more with less thanks to a virtualisation makeover.

In 1986, Attorney Nicholas Barrett founded Nicholas Barrett & Associates with just himself and an assistant running the business. But over the last 24 years, that small two-person office has grown into a bustling 45-person law firm specializing in litigation, real estate law, collections, and loan servicing.

Like any busy law office, Nicholas Barrett & Associates is a document-driven business that depends on reliable e-mail and file servers to meet clients' deadlines. However, over the years, the company's 12 rack-mounted 2U white-box Windows 2003 servers utilized for file and print, email, application, web, SQL and document storage, had become increasingly unreliable.

Further, the company's infrastructure had become prone to crashes due to single points of failure including switches, hard drives, and RAID controllers. They were also running out of space in their small server room inhibiting expansion of their network infrastructure. Cooling issues and overheating were also wreaking havoc on their network. After suffering from several serious crashes that created days of down-time and lost productivity, Nicholas Barrett called my team at PC Troubleshooters.

A Simpler Solution

Rather than waste the company's time and money overhauling each of the 12 aging servers individually, we opted for a simpler, more streamlined approach. In one fell swoop, we replaced all 12 servers with a single IBM Blade Center S Chassis with six HS21 IBM Blades. This solution has reduced the rack footprint of the server room from 24U down to 7U, allowing plenty of room for expansion in the previously cramped data center. This move reduced the amount of power consumption and heat generation by about 50 percent, which has reduced the company's heating and cooling expenses and electric bill by approximately $300 per month.

Within the Blade server, we virtualised the 12 existing machines using Citrix XenServer. By virtualising the office's servers with Citrix, we have consolidated and reduced their reliance on many physical servers. Now NBA has the capacity to easily expand their network infrastructure to accommodate the law firm's rapid growth without purchasing more hardware. It also provides the ability to quickly and easily backup and restore their data should disaster strike.

Disaster Recovery

Images of the firm's virtual servers are now kept off-site in secure co-location facilities. This enables NBA to recover their systems quickly (in minutes, rather than days) in case of power outages, fire, theft or even human error.

We created our own backup and disaster recovery system by deploying a network-attached storage device onsite and using StorageCraft ShadowProtect software to image servers on an hourly basis. Each image is encrypted and sent to two separate storage facilities in Maryland and Colorado.

The Payoff

This virtual server installation is a strong first step toward greening Nicholas Barrett & Associates' IT infrastructure. The firm is now using less power to operate its server room, saving $3,600 annually in electricity costs.

Because of the Blade Center S's high fault tolerance, the servers are less prone to costly down time, which means substantial savings in productivity throughout the firm. The Blade Center offers no single point of failure. It has redundant power supplies, hard drives, RAID controllers, switches and network cards, so that any single failure will not take down the system.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
