Server virtualization has been a revolutionary datacenter technology for those who administer and manage it. Unfortunately, not many companies are 100 percent virtualized. Although it has gained its market share for quite sometime, Server virtualization technology is far from being mastered, especially in large enterprises and datacenters. There are benefits in server virtualization technology that stakeholders and technical personnel must know.
By collapsing physical servers into virtual servers and reducing the number of physical servers, your business will save in power,carbon footprint and cooling costs. Additionally, youll be able to reduce the datacenter footprint which can include diesel generator costs, UPS costs, network switch costs, rack space and floor space. End users will be more productive thanks to less downtime and much more. Workstation, server maintenance, upgrades and replacement are cheaper when you only have to take care of one physical workstation/server.
Nine out of ten IT departments spend at least half of their time doing routine administrative tasks. Virtualization can automate and simplify those administrative tasks, such as managing server workloads, monitoring performance, adding / removing hardware resources, organizing server roles, prototyping, moving and cloning.
You can move a running virtual machine from one host to another with no downtime. For example, VMwares vMotion can do this for you and that feature makes other features like distributed resource scheduler (DRS) and distributed power management (DPM) possible.
By being able to back up and restore entire virtual machines, you can much more quickly back up the VMs and put them back, if needed. With image-level backups, it makes disaster recovery a lot more easier thanks to snapshot technology. Any blocks that needs changing can be be backed in the middle of the day. With IGS and VMware virtualization you can backup a server in three different levels: server level, application level, file level; thus you can easily restore a single file, a single mailbox, a single mail or database, or even a whole server quite easy.
By being able to create a virtual lab, you can test vSphere, Exchange, Active Directory and much more. This would have costed more if one is using physical servers.
As virtual machines are hardware-independent, you can restore image-based backups on any hardware that is capable of running vSphere. Software features like site recovery manager (SRM) automate the testing and failover when a disaster strikes. IGS AVM Enforce managed services helps monitor your datacentres from downtime and help restore your data should anything happens to your datas. 7. Improves server security
You can create virtual networks to isolate entire virtual server farms as needed, improving the security around your sensitive datas.
