Virtualization will have a dramatic impact on credit union data centers during the next three to five years, according to “Server Virtualization,” a white paper from the CUNA Technology Council.

Credit unions at all asset levels are pursuing server, storage, and desktop virtualization—focusing first on server virtualization. The chief impetus for the shift, notes the whitepaper, is to put the brakes on server sprawl, which contributes to a mushrooming physical footprint and expanding energy costs for power supply and cooling.

Virtualization allows credit unions to place several servers that use different operating systems on one virtual machine host. With an average of 12 servers or more per virtual machine host (depending the machine’s processor), this reduces to a handful the number of machines used by even the largest credit unions. And it allows system administration to move from working on widely scattered physical servers to a centralized virtual monitoring system.

Virtualization also permits more flexibility—allowing quick addition and deletion of virtual machine servers. A virtual system minimizes downtime for maintenance and testing, explains the whitepaper. While it used to take an average of two days to bring online a new physical box server, in a virtual environment, a credit union can add a server in a matter of hours or even minutes. This is important for two reasons—software testing and migration of data for backup and disaster recovery.

The whitepaper offers 10 tips for credit unions planning to move toward virtual servers:

Great article! Unfortunately, most employees don’t feel valued or appreciated by their supervisors or employers. In fact, research has shown that the predominant reason team members quit their jobs is because they don’t feel valued. This is in spite of the fact that employee recognition programs have proliferated in the workplace – over 90% of all organizations in the U.S. has some form of employee recognition activities in place. But most employee recognition programs are viewed with skepticism and cynicism – because they aren’t viewed as being genuine in their communication of appreciation. Getting the “employee of the month” award, receiving a certificate of recognition, or a “Way to go, team!” email just don’t get the job done. How do you communicate authentic appreciation? We have found people have different ways that they want to be shown appreciation, and if you don’t communicate in the language of appreciation important to them, you essentially “miss the mark”. Additionally, employees need to receive recognition more than once a year at their performance review. Otherwise, they view the praise as “going through the motions”. A third component of authentic appreciation is that the communication has to be about them personally – not the department, not their group, but something they did. Finally, they have to believe that you mean what you say. How you treat them has to match the words you use. If you are not sure how your team members want to be shown appreciation, the Motivating By Appreciation Inventory ( will identify the language of appreciation and specific actions preferred by each employee. You then can create a group profile for your team, so everyone knows how to encourage one another. Remember, employees want to know that they are valued for what they contribute to the success of the organization. And communicating authentic appreciation in the ways they desire it can make the difference between keeping your quality team members or having a negative work environment that everyone wants to leave.
