Business consideration when building virtual network infrastructure
It's recommended to use a physical server hardware that’s HCL compatible and with the type of virtual environment you are trying to build. Usually, for businesses that are trying to virtualize servers in production you might want to stick with name brand server hardware such as Dell, HP, etc. Click here to check for HCL compatibility for VMWare virtualization.
You also want to consider having good amount of RAM on the server so it can handle the load of running virtual machines on your host system. This all depends on what type of virtual server that you are planning on running ex. MS Exchange, MS SQL, MS SharePoint, App Servers or any other type of virtual servers.
You may also want to evaluate what type of storage your VM's are going to reside on. Either on local server disks DAS (direct attached) or a SAN (storage area network), NAS (network attached storage) device. If your are planning on having shared storage you may also need to figure out if your are going to use iSCSI or Fiber to connect to your shared storage LUN's. When using a shared storage there is a good benefit that if you need live migration of your virtual machine such as a production Virtual Machine that runs 24x7 and the physical server needs maintenance you can move it over on to another similar hardware server and the users get no downtime.
The best thing of Virtualizing servers have is snapshots which is the premium benefit when it comes IT. Snapshots help when it comes to updating your VM Operating System or a currently working application needs to be reconfigured or updated. In virtual environment you can create the snapshot then do all your installs, updates, and if everything runs fine then you are good to go but incase if something goes wrong during update or install you can revert back to the working snapshot in no time.
Imagine doing that on operating system running on a single physical serve non-virtualized. Sometimes need to rebuild from scratch and doing restores from backups and going through installation steps of installed applications. That process could take hours or days to get thing backup.
Select your virtual server environment for ex VMWare or MS Hyper-V. You also need to get the proper licensing model to support your needs.
As part of our Managed IT solutions at Aarya Systems we helped businesses convert their existing infrastructure to virtualized. This has benefited then on energy & hardware cost cutting, and overall management overhead.
