When you choose a High Availability Virtual Dedicated Server from Micron21 we provide you a number of key features which increases the redundancy of your Virtual Dedicated Server.
How Micron21 High Availability and VMotion works
High Availability (HA) detects that a Virtual Dedicated Server has failed and starts it up automatically within our Micron21 vSphere infrastructure. VMotion allows Micron21 to move a running Virtual Dedicated Server from one physical server to another by quiescing the memory and copying it from host to host so that the running Virtual Dedicated Server is then hosted on another host without the user being aware that the Virtual Dedicated Server they are using has changed host. VMotion is also used for maintenance on our Micron21 infrastructure, moving running HA Virtual Dedicated Servers off without interruption doing away with scheduled down time to client services.
VMotion also works in conjunction with DRS (Distributed Resource Scheduler) which allows Virtual Dedicated Servers to be moved around physical hosts in our Micron21 vSphere infrastructure to optimise the resources available without user downtime. During a VMotion, the active memory and precise execution state of a Virtual Dedicated Server is rapidly transmitted over a high speed network from one physical server to another and access to the Virtual Dedicated Servers disk storage is instantly switched to the new physical host. Since the network is also virtualized by VMware vSphere, the Virtual Dedicated Server retains its network identity and connections, ensuring a seamless migration process.
