Case Study on how Server Virtualization increasing Productivity and Uptime:

Virtual Solutions Create Real Business Continuity


Business Challenge: Maintaining business continuity after any systems failure

The company addressed is a telemarketing call center that runs over 12 hours a day and 6 days a week. Legacy servers were beginning to fail causing a halt to company work. The older technology was causing an overall slowdown in users’ ability to access network and server resources. Server growth was beginning to become a challenge to manage. All of which was beginning to impacting the company’s ability to generate revenue.

Servers in use that had failed were custom built without fail safes to keep the servers running in case of hardware failure. When hardware had failed in the past, the data recovery for the application that the company relied on to conduct business had taken over 24 hours to restore. This in turn brought the company to a standstill, halting productivity and its ability to generate revenue. The company needed to develop a plan that would eliminate their frustrations, improve their productivity, and ensure the ability to grow in the future.

Implementation: Keeping the system operational while implementing the rollover

Due to the timeframe which the company conducts business, a plan for failover was developed to maintain maximum uptime. The idea for the new network was designed keeping the following in mind: The need to develop the network with a quick recovery process in the event of a critical failure as well as a server system that would be recoverable in the least amount of time, with the ability of users to continue company work.

The components needed for the implementation of the new system were a Network Attached Storage device with failover and two identical servers using the latest Windows operating system on a virtual platform. The use of identical virtual servers allows instant failover to the backup server in the event that there is either hardware or software failure. The servers not only had the virtual redundancy protection but had failover built into the hardware through multiple hard drives, fans, and other components.

A critical concern of the company was the downtime that would affect users of the network while this migration took place. To address this concern the entire system was built offsite in a laboratory environment allowing the builders to do two things: test the failover of the setup, as well as to simply bring the newly built setup back onsite as a quick replacement of the existing systems.

The rollout of the systems happened over 1 day on the weekend. During the company’s normally scheduled down-time, user systems were modified and final tests were run to ensure system reliability.

Results: What were the benefits?

Implementation of the highly redundant virtual server systems improved user’s ability to access data and applications on the network faster than they ever had before, allowing 30% more calls to be made per user throughout a work shift. With the increased redundancy and network failover, overall system uptime has gone from 82% availability to 99.9%. As stated by the VP of operations “Their knowledge, design and management skills have enabled our company to seamlessly replace our older technology with minimal impact on our call center of over 270 users.”
