  4. Virtualisation and Availability Virtualisation Benefits....... Virtualisation brings its own availability tools But virtualisation could be its own worst enemy when it comes to availability

  5. VMware tools the VMotion® and Storage VMotion functionality in vSphere makes it possible for organisations to dramatically reduce planned downtime VMware HA provides rapid recovery from outages shared storage is a single point of failure local availability only VMware fault tolerance provides continuous availability shared storage is a single point of failure local availability only

  6. Hyper-V tools Hyper-V™ live migration allows you to move running VMs from one Hyper-V™ physical host to another

  7. Hyper-V tools failover clustering at the Hyper-V host level shared storage is a single point of failure local availability only clustering at the Hyper-V guest level shared storage is a single point of failure local availability only clustering at the Hyper-V guest level on a single physical server Physical server is a single point of failure shared storage is a single point of failure local availability only

  8. Virtualisation disadvantage? Some HA techniques and technologies, however, outstrip the capabilities of virtualisation platforms what do you do if you run more than one hypervisor? how do you protect a mixed Physical and Virtual environment? what do you do for DR? what happens if you use more than one storage platform or vendor?

  9. Is This Your Real Environment?

  12. Double-Take Full Server Failover At failover time, the system state of the source is merged with the target server After reboot, the target server now has the identity and data of the original source If App_Svr_1 goes down, will failover to App_DR_3. The source image is mirrored to the target server App_DR_3 App_Svr_1 App_Svr_1 Custom App Custom App Custom App Real-time Replication continuously protects the source Data Data

  13. Source and Target swap roles. Subsequent Failover will move App_Svr_1 back to the original source server. This same “Reverse” technology also works for VMware ESX VM’s Double-Take Full Server Reversal On Reverse, the system state of the original target is merged with the original source server The original source comes back on line. The application and data are mirrored to the new target server App_Svr_1 App_DR_3 App_Svr_1 Custom App Custom App Real-time Replication continuously protects the source Data Data
