Virtualization Keeps the it systems running andthe Water FloWing in tampa Bay

Tampa Ba Water is an agenc o the State o Florida that supplies water to nearl 2.5 million people

Tampa Ba Areathe 19th largest metropolitan area in the United States.

Most people have just one expectation when turning on the tap: that water will come out. At Tampa Ba W

it's their job to make sure these expectations are met. Fulflling this mission requires a sophisticated arsenal

behind-the-scenes technolog , including an extensive computer s stem or H drological Water Modelin

Supporting this new water modeling s stem put serious demands on Tampa Ba Waters IT in rastructure.

1U servers turned into ten, then into 20, and so on, sa s Steve Kroesen, network s stems administrator o

agenc . We reached the point where we were maxing out our uninterruptible power suppl (UPS).

Tampa Ba Water looked at the side o its production environment which didnt involve the modeling s st

and which was highl under-utilized rom a CPU perspectiveand saw a good ft or a virtualization s

based on VMware and Intel technologies. The compan purchased our HP DL580 servers with Inte

processors to drive consolidation o new and existing s stems. This e ort allowed Tampa Ba Water to

two ull racks or the water modeling s stem, providing enough available power and air conditioning to r

entire environment. It turned into a win-win solution or us, sa s Kroesen.

HIGHLIGHTS

CHALLENGE

Data center is pushing limits o power, cooling,and rack space

SOLUTION

VMware and Intel technolog allows users tovirtualize and consolidate underutilized servers,

reeing up data center space.

VMWARE AND INTEL AT WORK

VMware In rastructure 3 Enterprise, eaturing:ESX Server 3

HP DL580 servers with Intel Xeon pro-cessors attached to EMC CX-320 SAN

Virtualized Applications: homegrown appli-cations specifc to overall utilit unctioningand water orecasting

RESULTS Achieve 11:1 server consolidationratio. Tapping into the Intel Xeonprocessors inside our VMwareESX h pervisors lets us easil run45 virtual machines on just ourph sical hosts, sa s Kroesen. Werun VMware Distributed ResourceScheduler (DRS) in our environmentwith great success and have theabilit to easil VMotion between allhosts in the cluster.

Decrease power consumption b 30percent. Our UPS was hitting 80-85percentthe range where it startssending out alerts, sa s Kroesen.Virtualization helped us bring ourUPS back down to 50 percent.

Reduce server count b 28 perceIn our main acilit , we hseven racks, and weve been abto completel empt two o thb leveraging VMware and Intechnolog , sa s Kroesen.
