HA, DRS, VMotion and Storage VMotion

We will analyze the most powerful tools VMware infrastructure d.

VMotion
VMotion is an essential tool in the virtual infrastructure, which basically allows moving a virtual server from one node to another ESXI.
This option is really interesting because, to use, we will have no loss of service connection or drop the move equipment. This is because the file system using the ESXi, called VMFS.

Once you configure your network for VMotion, we do a test migration. Migration can be hot or cold, that is, with the server on or off.

VMotion is essential to create dynamic datacenters and automated. Now you can perform the maintenance of physical hardware if nafectar business continuity in any respect. It is a technology of 2004 or so, meaning that, at the time of writing, is a development of more than 8 years.
To connect the nodes to the storage and use VMotion, you can connect from a SAN (Storage Area Network) fiber, also supports compratibilidad with NAS (Network Attached Storage) and SAN iSCSI storage systems that are economic.
Migration tasks have priorities and can be scheduled to be performed at a certain time of day. Because we could have a problem if you move a virtual server when you have to move for some reason.
Suppose we are performing a configuration task uan NIC in a node, and an administrator puts a virtual server with VMotion destination node that we are fixing. Could lose the service and business continuity. To do this, the console has a view of all the tasks performed in vCenter.
