The Transition BeginsIn the late 80s, prices started to dropEnvironments no longer sharedDevelopment acceleratedShift from operational excellence to market speedShift from rigor of design to management of:
Server names and WINSIP addressesCablingSubnetsWINSLicenses
One Day, We Took a BreathWe found hundreds, sometimes thousands of serversWe found higher ratios of IT staffWe had difficulty managing service levelsWe found unlicensed softwareWe found security issuesCosts out of controlServers not being utilized
But…it was the right thing to do!
What Lies Beneath?Approximately 40% of Windows servers are > 3 years old
Rack spacePower consumptionWeight and BTUs
The average utilizationProcessor utilization: 6%Memory utilization: 50%Disk busy: 1%Disk capacity: 10%NIC busy: 1%
20 to 50% more servers than expected
The Impact of Excess Capacity
More to: SecurePatchMonitorStore, heat, cool and power
Troubleshooting is more complex
Reason for ConsolidationThe Reasons for Consolidation Help Shape the Assessment

Dispose of Old ServersSince June, the average number of servers 700MHz or less is 28%The average rack size of a server with CPU <= 700 MHz is 7Client with 1000 servers
280 with <= 700 MHz processors1960 rack units (approx. 50 Racks)446 Watts/Hour average = 125 KW/Hr
Just switching to blades280 with 2.8Ghz processors6 rack units36 Blade Chassis @ 3000 Watts/Hour = 108 KW/HrReduced cablingImproved manageability
Virtualizing increases the opportunity even more
Test and DevelopmentGreat opportunity for virtualizationProves the technology is ready and prepares for next stepsConsolidate servers that service infrastructure
Proves you willingness to consolidate yourselfProves new technology
Clients report that 25% to 50% of their environment is test / dev / BCPConsider concurrency
What percentage of your test / dev servers are actively being used at any time?Could management software that schedules deployment of environments to a sandbox reduce requirements even further?
