The backup system not only protects data, but also ensures business continuity

Backup is mainly aimed at factors such as human misoperation, virus infection, logic errors, etc.

Data recovery, data backup is generally carried out in the same data center

The disaster recovery system only protects the recoverable version data at different time points

Disaster recovery is mainly aimed at major natural disasters such as fires and earthquakes. Therefore, there must be a connection between the production site and the disaster recovery site.

A certain safety distance must be maintained

Configuring the cluster HA strategy is to automatically adjust the resource load balancing on different hosts

Dedicated failover hosts refer to: setting a specified number of hosts in the cluster to fail, the system

Periodically check that there are enough resources left in the cluster to fail over the virtual machines on these hosts

To allow host failure in the cluster refers to: Reserving a designated host as a dedicated failover host, when the host is used as a failover host, ordinary virtual machines are prohibited from starting, migrating, waking up, and snapshot recovery on the host

HA resource reservation is to reserve CPU and memory resources according to the configured values ​​in the entire cluster

TRUE

FALSE

IMS is an independent service and has no relationship with other services.

The BMS needs the IMS to provide an available image in order to create it normally

ECS promises to provide a usable image from IMS before it can be created.

Users can convert ECS into a private image.

Compared with the complete copy template, using the fast encapsulation template to issue virtual machines is faster and more efficient

There is no essential difference between full reproduction and rapid distribution

using sysprep package

Rename and add domain by the application in the virtual machine

Through routine monitoring, find the running status, login status, allocation status, and performance consumption of the current user's virtual machine. Abnormal registration situation

By routinely monitoring the status of the gateway, monitor the CPU, memory and traffic of the gateway and its users within a period of time

Whether the number of used resources matches

The risk of slow operation of the operating system can be ignored, and it is recommended that the user's virtual machine be kept powered on all the time

In order to ensure that backup data is available when the system is abnormal, it is necessary to regularly check the availability of backup functions and data

The disk has bad sectors, resulting in the loss of the virtual machine xml file.

There are too many service virtual machines on FusionCompute and insufficient CPU resources.

When the FusionCompute is restarted, the virtual machine is in the process of full-machine backup, but the task is not completed.

Power on the CNA host first, and then power on the IP-SAN storage, resulting in abnormal data storage.

DNS configuration error

Cinder-volume node time is inconsistent

The back-end storage network configuration is incorrect

The network of the storage management plane is abnormal

Support VDC monitoring, provide comprehensive analysis and evaluation capabilities based on VDC, help users use resources reasonably, Ultimately achieve the purpose of improving resource utilization

Support resource pool monitoring, which can perform unified monitoring and monitoring of computing, storage, network and big data resource pools

Analyze, help users use resources efficiently and reasonably, discover potential risks and problems, and propose improvement measures or Guidance

Support physical equipment monitoring, and can monitor hardware equipment such as data center servers, storage, and network equipment.

Unified monitoring and management, providing all-round monitoring capabilities such as alarms, resources, topology and performance, helping users to Quickly locate and troubleshoot hardware problems

Tenant application monitoring is not supported. The application belongs to the user business level, and users need to deploy relevant monitoring by themselves.

The cloud platform itself cannot support tenant application monitoring

The user does not configure the NTP clock source, the user can check whether the

If there is any related alarm, follow the alarm handling help to configure the NTP clock source and clear the alarm

This phenomenon is caused by the inconsistency between the time of the NTP clock source and the local PC. The user can modify the time of the local PC.

time, consistent with the NTP clock source

When the key is updated, the business process on the node will be restarted, which will cause abnormal monitoring of the virtual machine.

The phenomenon is caused by the abnormal monitoring process. The user can use "PuTTY" to log in to the main machine as the gandalf user

VRM, restart monitoring process

Modifying the IP address of the clock source server 1 will automatically restart the business process of the VRM and the host, affecting the current business operate

Manually restarting the VRM node database will cause the database to be lost and cause the task to become unresponsive

Modifying the password of the internal docking account will not affect the business operation but will cause all accounts to be unable to log in

Enabling the IP and MAC binding function in the port group will cause some 1P addresses of the network card to communicate abnormally

When the VCPU usage of the virtual machine is less than 20%, the reuse ratio is set to 200%~300%

When the VCPU usage of the virtual machine is greater than 20% and less than 30%, the reuse ratio is set to 200%~300%

The VCPU usage rate of the virtual machine is more than 30%, and the reuse ratio is set to 100%~200%

When the VCPU usage of the virtual machine is greater than 10% and less than 20%: the reuse ratio is set to 300%~400%
