- Hyper Clone does not support consistency groups.
OceanStor UltraPath
- Storage resource allocation is not implemented in OceanStor UltraPath. Implemented functions include path selection, controlling access to storage devices and improving path reliability between host/storage.
HyperClone
- Full data copy of the source LUN is correct as a tool for HyperClone.
CIFS and NFS
- Wrong description about CIFS and NFS is CIFS is easier to use than NFS, but additional software must be installed on the host.
RDMA wrong description
- Low response of Remote Direct Memory Access (RMDA) is wrong. The better attributes would be high throughput, less CPU resource usage and low latency.
Licence management of devices
- Loading the license operation cannot be performed in the Licence Management interface of DeviceManager.
DeviceManager interface
- DHA operation log files can be used to collect hard disk operation logs, I/O statistics, SMART and other log information within the DeviceManager interface.
OceanStor Pacific access control
- OceanStor Pacific access control policy used is RBAC.
Hyber Storage Snapshots
- After creating a snapshot, during the redirection write process, overwriting does not require reallocation of space is wrong for Huawei snapshots
CLI Commands
- The CLI command used to query the version information of the current storage system to accurately determine the supporting software version during maintenance is "show system general".
HyperCDP interval
- The minimum interval to creating HyperCDP in a scheduled HyperCDP plan in Huawei all-flash storage is 3 seconds.
Logical Port
- A logical port is a virtual port assigned a unique IP address and is used to carry host services.
Expansion Methods
- Wrong description of the two expansion methods, Scale-Up and Scale-Out, includes While using Scale-Out for expansion, management complexity will increase later
Restoring snapshots
- To minimize data lost use the 11:00 snapshot is to be restored a business LUN on the storage at every hour every day if a new employee of the company accidentally deleted business data generated at 9:30 am at 11:30 am
Dual contoller configuration
- When dual-controller storage is running in HA mode, only one of the two controllers is working at the same time, and the other is in "Waiting, synchronizing, and monitoring" state
Multipath algorithm
- A polling algorithm is used, the multipath will select each path in turn to send I/O data based on the currently available paths of the application server and storage systems
Distributed Storage System
- A manufacturer's distributed storage system was put into operation for 100 days, running 24 hours a day. A failure occurred on the morning of the 10th day for 1 hour, the 25th day for 4 hours, and the 80th day for 1 hour, system availability is 99.75%
Edgy IT architecture
- An edge IT infrastructure solution with integrated design and whole cabinet delivery, mainly used in edge branch offices and vertical industry edge application scenarios is Huawei Edge Data Storage
Correct Descriptions
- Servers are usually used to refer to computers with higher specifications in some enterprises,install some important software in the enterprise and run important business. ICT infrastructure should be built with high-end equipment with high reliability is incorrect.
Full-scenario data protection
- A warm data and warm archive is incorrect about about OceanProtect backup storage full-scenario data protection, use recovery for hot data, hot backup for warm data and warm archive for cold data
Disks numbers and domain number
- With fully utilize the performance of the disk by having 96 disks in a disk domain of Huawei OceanStor hybrid flash storage system recommends for at least 32 LUNs.
Data compression characteristics
- Some data information may be lost is wrong in relations to data loss, the data compression characteristics should do the reverse.
Network Files
- Description about NFS (Network File System) allows clients with the same operating system to share files with each other is wrong. This protocol is popular for Linux/Unix environments.
Backup networking
- If the production environment server performance is high, the production network resources are relatively tight, the budget cost is limited, the daily backup data volume is 1~2T, and the backup time is 3 hours, 10 GE lan-base backup networking method is most suitable.
FE 25Gb RoCE
- Module supporting FE 25Gb RoCE is used for connecting to the application server for Huawei OceanStor Dorado V6
Descriptions of data
Data is information that has been processed and has logical relationships is wrong. Processing turns raw data is data into relationship data.
Maximazing space
- The company's backup data volume is small and it can take more time and save storage space with Differential incremental backup
Average Daily
- A customer's initial backup capacity is 1T, and the average daily data increment is 10GB. The backup capacity be no less is the result of of a full backup every Monday, and a differential backup every Tuesday to Sunday for 4 weeks.
SAN and DAS
- Both DAS and SAN are external storage, so storage resources can be easily shared
Openstack Drivers to use
- Huawei with distributed block storage needs The cinder driver.
