Read and write strategies include permanent, default, recycling.

Recycling strategy is suitable for business scenarios that require high performance and small amount of data.

Select out the recycling strategy when the data or write data is the lowest priority.

Resident strategy is suitable for large read and writedata, and read-only scenes.

When smart LUNs act as backup media, smart tier'sperformance 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 types of quotas include capacity quota and file quota.

Quota methods include calculating quotas, soft quotas and mandatory quotas.

Thesystem pre-allocates quotas for files before writing the file. When the user cancels the writing of the file being written, the system does not release a pre-allocated quota.

When the user continues to write data, the quota information has been used inthe InfoAllocator interface real-time updates.

A bank has more than XX customers and XX corporate customers.

Loss of data will result in substantial loss of business interruption and may also result in significant financial loss.

Business interruption has a huge impact, and the interruption time of business deployment <2h.

Customers want to build two live-action data centers in the same city and realize double-live of the key business systems. The disaster recovery plan RPO = 0, RTO = 0

Multiple LUNs for Customer Business. When implementing data migration using remote replication, you need to add multiple remote replication tasks to a consistency group

Use remote replication to complete online data migration

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 reduce costs 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 ofSSD data, use a tiered storage disk for more utilization

According to the different retention time to divide the media pool

As many media pools as possible to improve performance and utilization

According to the purpose of the disk to partition the media pool

According to the number of storage strategies or use to divide

Create a mirror LUN for a common LUN. Due to internal information exchange, the LUN ID for hosts’ read and write I/Os changes based on the information exchange result.

A LUN stores 2 GB of data. Create a mirror LUN for this LUN. During the creation, the system automatically generates a copy. The total data amount of the copy and mirror LUN is 4 GB.

HyperMirror can be configured for external LUNs, and external LUNs can be configured as HyperMirror copies.

When configuring HyperMirror, its copies must come from different disk domains.

The first time you configure and use eth1, you can directly configure the network port IP on the VTL console

In the command line configuration management network port directory / etc / sysconfig / network-scripts

In the command line configuration, you need to log in to the VTL operating system, the user name is root

After the command line configuration is complete, you need to restart the network service by running the service network restart command

When an IO arrives at the storage system, in order to avoid affecting the write performance, the data in the smart cache will not be any changes dueto the IO

When reading the data in the missing smart cache, the smart cache pool directly forwards the read IO request to the HDD

If OceanStor V3 is shared between services A and B, the same custom smart cache partition can be used

The system generates a default smart cache partition for each controller by default

windows operating system can create up to 4 partitions

Single partition capacity size limit of1TB

The total number of primary partitions and main expansion partitions does not exceed 4 and the maximum number of primary partitions 4

The maximum number of logical partitions on the main extended partition does not exceed 4

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.

The mode of operation of the array can be in-controller load balancing or inter-controller load balancing.

Load Balancing Mode Including wheel training algorithm, the maximum queue depth algorithm, the maximum workload algorithm.

After the connection is interrupted between the LUN home controller and the host, the host accesses the LUN through the peer controller. In this case, the over-trail software defaults the switched home controller of the LUN to the remote controller.

When multipath detects a preferred controller failure recovery, the I / O is resumed immediately at the preferred controller by default.

VxFS is a non-log file system that can support morethan 2T files.
