VMware TCO/ROI Calculator for CMC Careers VMware Infrastructure This 3-year analysis for CMC Careers calculates the estimated total cost of ownership (TCO) comparison between your current (As Is) environment and implementing the proposed VMware solution. Based upon the information provided for the 10 server environment, implementing VMware Infrastructure provides a potential direct savings of £ 43,012 and an indirect savings of £ 8,661 over 3 years. With the proposed VMware Infrastructure solution, the following can be achieved: Reduce the number of servers through virtualization, reducing servers from 10 to 2, a savings of 80.0% - with a target consolidation ratio of 5.0 to 1. With the virtualization of servers, consolidating SAN networking costs, helping to reduce the number of host bus adapters from 0 to 4, saving -4 HBAs and reducing SAN switches from 0 to 2, saving -2 SAN switches. With the reduction in overall number of servers, reducing operating power by 2.842 kWatts, cooling power by 3.550 kWatts, and data center space savings by 0 square feet. A reduction of 74,882 lbs (34 tons) of carbon emissions, equivalent to the average emissions of taking 6 cars off the road per year. Achieve an ROI of 503.9% from an investment of £ 10,255 in VMware Infrastructure, and projected direct savings of £ 43,012, indirect savings of £ 8,661. Cumulative 3 Year TCO Comparison

With individual servers before VMware, it typically takes on average 20 hours to build / rebuild and reload a server. With VMware, these tasks are consolidated to redirect virtual disk to new VMware virtual machine instance. Since tools and applications are already loaded these tasks can be avoided.

v2.1
Appendix A: Details for VMware Infrastructure (continued) VMware TCO Advantage Over Other Virtualization Products When comparing costs of VMware products to costs of other virtualization products, it is important to account for the scalability benefit offered by the advanced technology in VMware Infrastructure. VMware Infrastructure typically supports double or more the number of concurrently running virtual machines on the same server hardware as do competing products from Microsoft or Xen. That scalability advantage stems from our support for memory oversubscription - a VMware exclusive - and also from our direct I/O architecture. VMware Infrastructure memory oversubscription permits the aggregate memory allocated to the virtual machines to exceed the physical memory installed in the host server. VMware enables memory oversubscription with exclusive technologies that reduce host memory requirements: Transparent page sharing examines every memory page stored by the virtual machines to identify similar pages and store only one copy. For example, if several virtual machines are running Windows Server 2003, they will have many identical memory pages. Transparent page sharing consolidates those identical pages into a single memory location. Only VMware has this powerful virtualization feature. Idle virtual machines would normally consume their full allocation of memory. To make better use of those wasted resources, VMware Infrastructure uses a memory balloon driver to artificially exert memory pressure on idle virtual machines so that they page out their memory to disk. This frees up memory that can then be used by active virtual machines.
The result of this innovative technology is the ability to run, on average, twice as many virtual machines on a VMware Infrastructure host without sacrificing performance as you could run on a competing platform. In fact, a 2:1 memory oversubscription ratio is conservative and much higher ratios can often be attained. The impact of memory oversubscription on TCO is dramatic because half as many VMware host servers will be required to support the same number virtual machines. Another contributor to the better scalability of VMware Infrastructure is the direct driver model we use for virtual machine network and storage I/O. VMware places the device drivers for physical network and storage adapters directly in the ESX Server hypervisor. That lets us optimize I/O operations for the unique workloads generated by multiple virtual machines. Competing hypervisors channel all virtual machine I/O through generic Linux or Windows drivers in a general purpose management operating system, which results in resource contention and bottlenecks. The VMware direct driver architecture supports more concurrently operating virtual machines than does the indirect driver design of the competition.
