Virtual Server Disaster Recovery

Virtualisation of Linux and Windows Servers

Application recovery for all virtual environments including VMWare, Xen and MS Virtual Server is achieved by using LifeKeeper in both the host and guest o/s. All Windows and Linux solutions are available in both physical and virtual environments.

We can recover virtual environments at application level with no requirement for a SAN. The same solution is used for both local and remote server recovery, and will accomodate disaster recovery of both physical and virtual environments to a virtual environment.

Physical to Virtual or Virtual to Physical recovery

A physical infrastructure replicating and recovering to a virtual infrastructure. Here the advantages of virtual machines are realized, as there is no need to purchase many redundant servers. And one physical server can be used as a hot backup for many physical servers.

Virtual to Virtual recovery

Virtual servers, used as backups for virtual servers. A truly consolidated infrastructure.

In addition, the requirements for recovery can be chosen from:

Local recovery

Where both active and standby servers are on the same Local Area Netowork.

Remote recovery

The standby server is in a separate building, or site.

Both local and remote recovery

There is a local server and a remote server on standby. A belt and braces approach which invokes a local recovery for ‘everyday’ scenarios, and a remote recovery for disasters.

Can have applications running within virtual servers protected by LK or have the whole virtual environment failing over.

Virtual Centre protection

The only solution that fully protects VirtualCentre and provides mirroring, monitoring and recovey of VirtualCentre servers. Removing this single point of failure.

The LifeKeeper Protection Suite for VMware VirtualCenter solution protects VMware Administrators against the following negative impacts of planned or unplanned downtime:

• Loss of Centralized Management of VMware Servers
• Loss of VMotion and DRS capabilities
• Loss of ability to centrally provision virtual machines
• Loss of ability to centrally manage task scheduling and alerting - Loss of ability to centrally monitor performance & utilization of physical servers and virtual machines
• Loss of detailed centralized reporting of CPU, memory and I/O performance
• Loss of ability to configure/manage VMware HA
