How many disks are recommended for each disk domain?

Dear Axe,

Have a good day.

By default, each disk domain contains 48 disks. For some I/O scenarios, such as OLTP and VDI, the default disk domain configuration is recommended. For high-bandwidth scenarios, such as OLAP and HPC, it is recommended that a disk domain contains only 12 disks.

For special scenarios, or if customers have special requirements, contact Huawei storage performance department.

For expanding disks to the disk domain, you can check:

Thanks.

Hi friend! hope below can help u:

You are advised to configure a maximum of 100 disks for each tier in a disk domain. For example, if the number of disks on a tier is D (divide D by 100 and then round off the result to N and the remainder is M), you can refer to the following configurations:
If D ≤ 100, configure all disks on this tier in one disk domain.
If D > 100, create N+1 disk domains and evenly distribute all disks to the N+1 disk domains. That is, the number of disks in each disk domain is D/(N+1). In addition, it is recommended that disk enclosures be fully configured.
For SmartTier, it is recommended that a maximum of 100 disks be configured for each tier in a disk domain. The configuration of disks on each tier is the same as the preceding principle.
