Huawei Oceanstor 9000 can configure different data protection levels for different directories / files.

Data written to Huawei OceanStor 9000 system will be divided according to the size of 4G chunk.

Every N chunk, according to Erasure code algorithm to calculate M chunk calibration fast.

The utilization of protected data space is about N / (N + M), the reliability of the data is determined by the value of M, the greater the M is, the higher the reliability.

A client business IO load random read that accounts for more than 60% using SATA, SAS for staging storage, use SSD to do cache, so it will effectively reducecosts and improve random performance indicators

If hot spot data is scattered and changing rapidly, it is recommended to use tiered storage

If there are many SSDs and hotspots, Smart Cache is the best choice

If you have a small amount of SSD data,use a tiered storage disk for more utilization

True

False

The local storage system does not occupy the local storage system when using LUNs in heterogeneous storage systems

For external LUNs, the local storage system can set value-added functions such as remote replication, snapshots, etc.

smartVirtualization uses multipathing software to connect heterogeneous storage in a multipath-redundant manner

smartVirtualization Dictate write data write efficiency is higher than the write-back efficiency

The automatically created Asynchronous Remote Copy snapshot can either be a private quick pick or a public one.

In a DR scenario, it is recommended to create a virtual snapshot of the secondary LUN and map it to the host for access.

In remote replication link networking, parallel networking is better than crossover networking.

The number of LUNs in the consistency group should be as small as possible, and only the LUNs that have write dependencies on the same application are placed in a consistency group.

CIFS does not allow multiple clients to access

The CIFS client writes the shared file and does not write to the storage system immediately. Instead, the file is saved in the local cache and can be read againImprove read rate, improve performance

CIFS does not support anonymous transmission and shared authentication access

CIFS supports a variety of character sets to ensure CIFS can be used in all language systems

After creating a mirrored volume for a normal LUN, the server read-write IO results in a change as a result of internal information exchange.

The amount of data actually stored on a LUN is 2G, thetotal copy of the data is 4G. A volume image is created for the LUN, the LUN is mirrored when the copy is generated during system creation.

You can configure a volume mirror for external LUNs or configure external LUNs as mirror copies.

Whenconfiguring volume mirroring, mirror copies are required from different disk domains.

When smart LUNs act as backup media, smart tier's performance improvement on this LUN is not obvious.

During the running of the business, the extent size can be adjusted by the size of the hotspot area to obtain better performance.

Literacy ratio in the 1:9 scenario, enabling the smart tier has greatly improved the performance of the business.

Smart tier has no effect on host performance during hot data migration.

The SVP needs to connect multiple engines through two PCI-e switches, and each engine's controller needs to be connected to a PCIe switch to ensure that the link redundancy provides reliability.

When the control plane is connected to the network, when the engine and the PCIe switch are interconnected, the port P0 of the A3 slot and the PCI switch PCI port can be used pick up.

Huawei OceanStor 18000 can be used to install SAS interface modules and interconnect disk enclosures in slot 0 and slot 5 of the Huawei OceanStor 18000.

Stop the current production business, delete the host mapping.

Adding the remote device to the original production side array.

With the disaster recovery array as themaster LUN and the original production array as the slave LUN, create the remote replication relationship between the DR and the production end and wait for the initial synchronization to be completed.

Create a virtual snapshot of the slave LUN and activate it, then map the snapshot LUN to the host for authentication.

After the snapshot LUN is mapped to the host, the host can read and write the snapshot LUN.

Afterthe verification is completed, stop the upper-layer service application, release the LUN mapping, and finally delete the snapshot.

Stop the snapshot before the host can write snapshot LUN.

Because computing tasks are designed for large file services, it is more appropriate to deploy with an 8-node OceanStor 9000 C node. The capacity on the use of 4TB SATA, to meet customer needs

Using Oceanstor 9000 C Node combined with the total bandwidth and total capacity requirements, consider the 8-node configuration 4TB SATA full disk, backend 10GETOE + front-end IB networking

From the reliability point of view, it is recommended to use the InfoEqualizer function to access the OceanStor 9000 storage through a domain name. The InfoEqualizer DNS segment needs to be considered and OceanStor 9000 back-end to interoperability

OceanStor 9000 supports front-end 10GE TOE + back-end IB networking, the front-end is easy to log in and manage with the management PC interworking, considering this networking solution can reduce the cost of front-end IB switches.

windows operating system can create up to 4 partitions

The client must also support the SMB3.0 protocol

Ifthe client has only one network port, you can not use the SMB3 function

If the client has a GE network port with the same type and number of ports, when the client uses SMB3 to access Huawei OceanStor 900, the client will establish multiple connection channels with Huawei OceanStor 9000

If the client has two or more GE and 10GE IB ports of the same type, after the SMB3 is applied, when one of them is disconnected from the network port, business will be interrupted.

TheSIR cluster of the VTL6900 supports global deduplication

The deduplication start time of the VTL6900 can be controlled automatically according to the policy

VTL6900 on the specified tape deduplication and remote replication is recommended at the sametime

VTL6900 deduplicated tape to do data archiving, the physical tape library in the NC is still non-deduplicated data

To prevent changes in the directory or file protection time because of the changes in cluster time, a directory or file is configured with WORM attributes. After the directory or file will use the WORM clock to time, set the WORM clock. When the system will be based on the clock, user’s file will not be modified over the protection period.

If the cluster time is earlier than the WORM clock, the WORM clock will be chased every hour for up to 138 seconds to adjust. If the cluster is after the WORM clock, the WORM clock adjusts to the cluster time.

When a directory is configured as a WORM root directory, all subdirectories, new directories and new files in the directory automatically get the parent directory of WORM attributes. These attribute parameters can only be configured when the WORM root directory is set. Only then the user’s view can not be modified.

WORM logs are used to record the logs related to WORM operations and record them according to the time. The monthly log is a file that can be modified and can delete the file.
