Both thick and thin LUNs can be created in the same storage pool.

If the performance tier of a storage pool uses the 8D+1P RAID policy, the owning disk domain of the storage pool must have at least 9 SAS disks.

The hot spare space of a storage pool comes from each member disk of the storage pool.

A storage pool can have three storage tiers, and each tier can have more than one RAID policy.

On the slots of the same position on both nodes, such as A3 and B3, you must insert the same type of interface card.

A5 and B5, A6 and B6 can be chosen to be networked, the key is how to make the network connections.

If the back end of the engine cluster is to be directly connected to four control enclosures, add one FC HBA card in slots A2 and B2 for the controller enclosure of direct connection.

A2, A3, A4and B2, B3, B4 can be plugged into a 1Gb iSCSI or 8Gb FC interface module to connect with the business network.

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 aboutN / (N + M), the reliability of the data is determined by the value of M, the greater the M is, the higher the reliability.

Info replication as an optional feature of Huawei OceanStor 9000de, the production sites and disaster recovery sites need only the production site to purchase info replicator feature of the license

Plan a separate directory for each type of service using the Huawei OceanStor 9000 system at the D and Y sites in the system's root directory as a remote copy of the master directory, and shared to the corresponding business server i

Because the client's business traffic is mainly concentrated in the daytime working hours, you can not set the replication zone bandwidth limit, the synchronization task on the non-workers make time, take full advantage of node bandwidth

For each type of business to create a pair for the type of business data replication synchronization

Host to the optical switch connection is abnormal.

When configuring the zone on the switch, configure the FC port and the host port that works in the working mode of the VIS6600T as atarget in one zone.

The working mode of the VIS6600T is abnormal because the initiator's FC port is connected to the optical switch.

In the working mode of VIS 6600T, the connection between the FC port of the target device and the optical switch is abnormal.

Support for SMB3 multichannel features that take full advantage of client-side multi-core CPUs and bandwidth resources to dramatically improve performance.

When a hard drive has multiple objects at the same time to write requests, support merged into a large continuous IO, significantly improve system performance.

Internal file system replication, without having to go through the client directly in the system to complete high-speed

Supports 10GE and PCIE networking, providing high performance through high-speed inter-node interconnection and reducing system internal delay.

You can plan back-end storage network for 9000 internal communications, without planning gateway address, and front-end network with the same network segment IP address.

Oceanstor 9000 front-end network and management network can be considered together, planning for the same network segment.

Back-end CE6850 switches need to use four stacked cables for stacking connection to ensure bandwidth requirements

The external NTPserver address and the Oceanstro 9000 front-end network need to communicate to ensure that the oacenstor 9000 system and client applications maintain time synchronization.

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated atthe same time.

Disaster recovery storage side of the database resides in the cache has not been written to the hard disk.

When creating a snapshot on the disaster recovery end LUN, the production end is copying data to the disaster recovery end.

The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy. The incremental data is abnormally interrupted during the synchronization process and has not been repaired.

If the system has monitored the file X hasbeen cached on Node B, the client client1 can read the file directly from Node B.

If the system monitors that node B has cached file X, then node A can read the file from node

After HUAWEI OceanStor 9000 processes the request for reading the file X from client1, the system reserves the message on both node A and node B.

If the system monitors that node A has cached file X, then node A only caches the data of file X and does not cache its verification data

In the absence of a third-party arbitration site, the quorum disk selects 3 LUNs of the same RAID group in the same array with a size of 1GB

Storage arrays include Huawei and IBM arrays. The arbitration disks are preferably configured on Huawei arrays

In the dual live scenario, when there is a third-party site arbitration array, the arbitration disks are placed on the third-party site arbitration array and an independent UPS power supply is deployed

inspection found that there is a fault condition disk in the arbitration disk, you need to promptly repair or replace the fault arbitration disk

In the backup parameter settings "max open files" parameter defines the maximum number of files to be read in parallel per channel, which is the RMAN MAXOPENFILES parameter

"Command line backup" and "Log Backup" select the storage strategy for the database and archive logs, both need to choose the same storage strategy

The "data files per BFS" parameter in the backup parameter settings specifies the number of data files that can be simultaneously written to the same Back Set number

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 canbe 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.

The namespace is automatically created when HUAWEI OceanStor 9000 isstarted with the same name as the system namespace.

Namespaces as the root directory of the entire system can not be shared and visited, only if ask the subdirectories below it can be shared and visited.

A unified namespace provide users with a unified storage resource pool to achieve the centralized management of storage space and distribution.

Each file share directory is a subdirectory of the namespace.

The data that has changed since the last backup is backed up.

Changed data backup since last full backup.

Full backup of all data.

After the initial backup data backup of all data.

Check if the size of the migrated file is the same as the original data.

Check if the number of documents corresponds to the original data

Check if each file with read and write permissions corresponds to the original data

Whether the time for reviewing the case file corresponds to the original data.

The service plane uses GE channels for data transmission.

The service plane connects the host IO channel, disk IO channel and GE switching channel.

Plane redundancy between each other, when the business plane fails, allowing the use of control plane transmission services.

When the GE switch channel fails, you can use the PCIe switch channel as a backup data transmission channel.

SVP needs to be connected to multiple engines through twoPCIe switches, and each engine controller needs to be connected to a PCIe switch to ensure that link redundancy and to improve reliability.

When the control plane is connected to a network, when the engine and the PCI-e switch are interconnected, the port 0, port A3 and PCIe port can be interconnected.
