Server Virtualization Virtual Server Anti-virus Server UDS Cbord Test UC - EMS SA – Thin Client Mgmt New Print Server Virtualization allows us to maintain one powerful piece of hardware instead of five or more individual pieces of hardware.

Benefits of Virtualization “Greener” Reduction in power consumption and physical waste. Reduces the number of physical servers to purchase($$$) and maintain(work hours and down-time). Improves Performance through resource allocation. Reduces server downtime due to hardware failures. If hardware fails, the virtual servers running on that system can be restarted on another host.

Concerns All eggs in few baskets – mitigated by hardware redundancy within each host as well as multiple hosts. Not suitable for all servers – high traffic servers may not work well virtualized. Ownership – with virtualization, there is little physical representation of the investment. More up-front cost – to initially get hosts.

Fail-over Virtual Host 1 Anti-virus Server UDS Cbord Test UC - EMS SA – Thin Client Mgmt New Print Server Virtual Host 2 Two or more virtual Hosts Some Virtual Servers on each Host Addressing ‘eggs in one basket’ concern. Virtual Host 1 is having problems. Bring up Virtual Servers on Host 2
