2 1. What is vstandby? New concept design of Virtual Standby Availability Solution Standby Availability Solution to configure standby virtual machine originated from source machine (physical or virtual) and bootable to provide an immediate switch-over recovery in the event of a failure of the source machine. Incremental changes made on the source machines are transferred to the host datastore so that the standby virtual machine can be started in the virtual environment from any specific bootable point-in-time snapshot. No need of standby hardware for standby virtual machine Standby virtual disk is created in virtual environment running on ESXi host. Standby hardware is not required for standby virtual machine. Also, multiple standby virtual replicas originated from multiple source machines can be consolidated into a single virtual Environment. NetJapan s in-house developed product vstandby is one of NetJapan s in-house developed products following after ActiveImage Protector and vmguardian. Copy engine built in vstandby and running in background is compatible with ActiveImage Protector. It has a solid reputation for its high performance and reliability. 2

4 3. Main Features of vstandby 3-1 Specifications and Main Features of vstandby -1 Standby Availability Solution provides affordable data protection using virtual replica of source machine Virtual standby availability solution, designed to create standby virtual replica of source mission critical server, provides affordable data protection, leveraging Vmware ESXi virtualization infrastructure s capabilities. Easy to Use Switchover Recovery Solution Standby virtual replica is bootable from the latest boot point prior to the source machine failure, ensuring business continuity with minimal system downtime. Schedule incremental P2V boot point snapshot Virtual Standby Availability Solution creates standby virtual replica of source physical or virtual machines, takes latent scheduled incremental snapshots of P2V updates made on the source machine and transfers them to the destination host that standby virtual machine is running on. The standby virtual replica is bootable in virtual environment from a specific boot point prior to the source machine failure. 4

5 3. Main Features of vstandby 3-1 Specifications and Main Features of vstandby - 2 Support for the free-license edition of VMware ESXi ESXi free license edition can be used as the host target destination for creating and maintaining a vstandy VMDK. Restore vstandby Virtual Machines back to the Physical Machines A vstandby virtual machine, including all the changes made while in operation on the ESXi host, can be restored back to the original source physical machine once reparations are complete. Physical to Virtual Migration of Windows Servers vstandby can be used to seamlessly migrate physical Windows Server machines to VMware ESXi virtual environments. Supports Windows Server 2003 and above. 5

6 3. Main Features of vstandby 3-2 How vstandby works - 1 SV1 SV2 SV1 SV2 HW HW vstandby VM VM ESXi SV1 SV2 SV1 SV2 Normal Operation Configures a standby virtual replica on an ESXi host using an existing physical or virtual machine as the source. Schedules can be configured to take incremental snapshots of changes made on the source machine, every one hour at the shortest time interval, and transfer them to the host that standby virtual machine is configured on. System Failure HW HW vstandby Boot up VM ESXi VM Source machine failing In the event of a failure of the source machine, standby virtual machine can be started in the virtual environment from any specific bootable point-in-time snapshot, ensuring continuous operation with minimal system downtime.

7 3. Main Features of vstandby 3-2 How vstandby works - 2 SV1 SV1 HW Restoration completed SV1 VM ESXi Restored by using vstandby BE. Restore back to the source physical machine A standby virtual machine can be restored back to the original source machine once reparations are complete. The machine is booted into vstandby BE and restored. The standby virtual machine, including all the changes made while in operation can also be restored back to the source machine. 7

The creation of standby virtual machine is only available on ESXi.

9 5. Installation Typical and Custom Installation Custom Installation does not allow you to select components to install or installation folder. To complete installation, you need to restart Windows. 9

10 6. Schedule Setting 1 (vstandby) 1 Select source disk Select the source disk to create standby virtual replica. 2 Target destination to create the standby virtual machine Type in the IP address for the target ESXi host. Select destination datastore to create the standby virtual machine. 10

11 6. Schedule Setting 2 (vstandby) 3 Standby virtual settings Default settings are configured. You can configure target destination and replica standby virtual machine settings. 4 Configure schedule settings Flexible weekly or monthly schedules can be configured to take incremental snapshots of changes made on the source machine and create boot points for synchronization. 11

12 6. Schedule Setting 3 (vstandby) 5 Option Specify scripts to run before / after taking boot point snapshots. You can also select performance levels. 6 Summary You can review the settings you configured. Click on [Finish] button to start creating standby virtual machine. 12

13 7. Schedule Setting 3 (vsphere Client) Incremental boot point snapshots taken by vstandby Incremental boot point snapshots are taken according to the schedule you specified and standby virtual machine is bootable from a specific boot point. Up to 30 bootpoints When the bootpoints are created over 30, the second oldest bootpoint is integrated into the oldest one. 13
