Pass the Huawei HCIA Storage H13-611_V4.5 Questions and answers with CertsForce

HyperMetro technology can realize that both the main and backup data centers provide services to the outside world. During normal operation, the business of the two data centers can

Do load sharing based on weights, there is no difference between master and backup, and respond to some users separately. The weight can be divided by region, or number

According to the center's service capacity or external bandwidth

Warm standby technology. When a data center failure causes the service to become unavailable, within the specified RTO time, you can

Automatically switch the service to a backup data center

The hot standby business is responded by the main data center. When a data center failure causes the business to be unavailable, the

Within RTO time, the service can be automatically switched to the backup data center

The biggest feature of multi-activity is that it will not cause waste of resources in the data center, and the data center carries application business operations.

Hot spare space cannot cross engine

RAID 2.0+ uses an independent hot spare disk

Chunk size and Extent size are not adjustable

Automatically reserve a certain amount of hot spare space in the hard disk domain according to the hot spare strategy

OceanStor V3 series products support 8 controllers, and the switching plane between the controllers is IP-based Scale-out interconnection

When the control frame of OCeanStor 5300 V3 is expanded from 2 to 4 controls, it can be directly connected or

Networking with switches

In the OceanStor V3 series of new-generation storage products, the back-end loops of the same SAS interface card can be mixed and connected

Ordinary disk enclosure and high-density disk enclosure

OceanStor V3 mid-range storage arrays use IP switches for interconnection, which has cost advantages. PCIe switches are dedicated

Switching, the cost is relatively high, mainly used in high-end storage

Users do not need to plan the storage capacity of SAN and NAS separately

Users can freely allocate storage to meet the needs of the application environment

Users do not need to be concerned about capacity utilization related to data block and file storage support

Users can realize the functions of NAS by buying a set of SAN

When the device is powered off, the safe disk stores the data in the cache to prevent data loss

When an unexpected power failure occurs, the BBU supplies power to the cache and safe disk

Safe disk cannot be used to store user data

Only the first two disks in the controller cabinet are used for safe disks

The storage system can generate a snapshot in seconds

The snapshot LUN cannot be mapped to the host

Complete data copying is unnecessary

data use mapping table lookup

Regardless of whether disaster recovery or backup solutions are used, compared with data during system failure, data for disaster recovery cannot be lost

Avoided

After the disaster, I hope to immediately access the backup on the remote device

The restored data hopes to meet the current work requirements immediately

The traditional use of software for data backup still has usage scenarios

Cloud computing is dynamically scalable

End users of cloud computing need to understand how cloud computing works

Cloud computing can provide virtual disk space

Cloud computing is usually used in business systems that require high performance and high response speed
