The GPU hardware virtualization technology virtualizes the graphics card into several VCPUs, and each VGPU is bound to a virtual machine.

The virtual machine directly accesses the VGPU as it accesses the GPU

GPU hardware virtualization supports up to 64 users sharing one GPU card

Through the management of graphical workstations, the graphical workstation can be imported into the desktop cloud solution, and sent to the desktop cloud solution.

End users provide the HDP protocol to access the graphics red workstation to obtain the 3D acceleration capability of the GPU

GPU pass-through technology binds each physical GPU to a small number of virtual machines, and the virtual machines directly access to GPU

When using snapshot comparison technology for incremental backup, it is necessary to retain snapshot data on the production side

Use CBT technology for incremental backup, which saves storage space compared to snapshot comparison.

If there is only disaster recovery, the production side has wrong operations, or the system upgrade fails, etc., it will be Synchronizing to the disaster recovery side will also cause data or business interruption.

The backup is generally performed periodically. Once the data is damaged, the data will be restored from the recovery time to the last backup time. data in between will be lost.

If there is only backup, the business cannot be recovered quickly, and data recovery takes time. During this time, the business cannot be used. For a certain industry, such business interruption cannot be tolerated.

If there is only disaster recovery, business can be quickly recovered and data can be protected.

Only when the virtual machine network card is in "SRIoV", "PF" or "PCI" pass-through mode can the hot migration function be supported.

During virtual machine live migration, if the migrated virtual machine has a large business volume or a large memory usage, it will lead to the hot migration time is longer, and it is recommended to perform hot migration when the business volume is small

When the load of most hosts is too light, the virtual machines can be integrated by live migration to reduce the number of hosts. Improve resource utilization and achieve energy saving and emission reduction

By default, the system interface will prompt a timeout when the hot migration time exceeds 12 hours, but the internal heat. The migration task timeout period is 24 hours, and the live migration will not be terminated until the system times out.

There is no need to uninstall and then reinstall the ITA during the recovery process

RTO is infinitely close to 0. Even if synchronous replication is used, the business still needs some time,

The smaller the RTO value, the less data is lost

The smaller the RPO value, the smaller the service interruption time.

In theory, RPO can be equal to 0. When disaster recovery or backup uses synchronous replication, the same

Step data, RPO can be achieved equal to 0.

If the operating system of the infrastructure server fails, you can create a new server and reinstall the software

And use the backup data on the backup server for data recovery

If there is a failure caused by some or all software of the infrastructure server, it is necessary to reinstall the software and take advantage of it.

Data recovery using backup data on the backup server

The recovery strategy includes software reinstallation recovery and system reinstallation recovery

If you need to restore WI data, you must use the system reinstallation recovery method

There are two types of A port group: common and trunk.

A port group can be configured with multiple IP addresses.

A port group is a distributed virtual switch.

All virtual ports in the port group have the same attributes
