Understand the Legacy Features of vSphere

Welcome to the legacy features of vSphere. They serve as the foundation that brings tremendous flexibility to managing an x86 environment. There are many legacy features, but we’ll be covering the top three here:

• vMotion, which offers the ability to relocate a running virtual machine or server from one physical location to another without any downtime.
• Distributed Resource Scheduler, which you use to make sure that your servers are balanced, getting the resources they deserve.
• High Availability, which ensures you’ll never have to rush into the office to address bad hardware.

vMotion

vMotion remains one of the most powerful features of virtualization today. With vMotion, you can perform work on underlying hosts during business hours rather than having to wait until the wee hours of the morning or weekends to upgrade BIOS or firmware or do something as simple as add more memory to a host. vMotion requires that each underlying host have a CPU that uses the same instruction set, because, after all, moving a running virtual machine (VM) from one physical host to another without any downtime is a phenomenal feat. VMware VMs run on top of the Virtual Machine File System (VMFS) or NFS. Windows still runs on New Technology File System (NTFS), but the underlying file system is VMFS-5 or VMFS-3. VMFS allows for multiple access, ....
