A deeper look at Server Virtualization

Why Consider VMWare for your infrastructure?

With the initiative in all companies now being to lower IT costs, the focus has shifted from physical, over specked servers to virtual servers; The goal being to create an environment of servers that consume a fraction of the power the physical servers consume and are much more flexible and scalable.

With Server Virtualization you gain:

Cost Reduction

Numbers indicate that at most, between 8% and 12% of CPU capability is consumed at peak periods...
In most cases, Server Virtualization has resulted in a reduction in Physical Servers by as much as a 20:1 ratio. This reduction in Physical Servers results in a reduction in hardware costs, licensing, cooling and management.
With Server Virtualization, existing hardware can be re-purposed, and utilization would be increased by as much as 80%.

Load Distribution

With VMware’s Distributed Resource Scheduler (DRS), Physical Servers are continuously monitored to ensure that the load is distributed evenly among the Physical Servers in the DRS cluster.
If the need arises for more resources, DRS automatically moves the Virtual Machine from one Physical Server to another that has the ability to handle the required load.

Faster Provisioning

No longer will IT be the bottleneck.
With VMWare, servers and workstations can be deployed within minutes.
If there is a need for the creation of several identical machines, these machines can either be deployed from a template of cloned from another Virtual Machine.

Availability

Vmotion – Maintenance windows are cut considerably.
Providing that shared disk and network are in place, VMotion, you now have the ability to migrate powered on Virtual Machines from one physical host to another if there is a need for planned maintenance.
High Availability – Clustering technologies are expensive and depending on the configuration, that cost extends from software licenses to dedicated standby hardware.
With High Availability, VMWare provides a cost effective solution to eliminate downtime in the event of Host (Physical server) failure and other unplanned events.
Once the Hosts are added into a HA cluster, the system automatically monitors and detects host failure and automatically restarts the Virtual Machine on another host in the cluster.
