Expanding the storage pool of FusionStorge

Dear, what's your Fusionstorage version?

Dear Axe,

① The capacity of the disk to be added must be greater than or equal to the capacity of the existing disk in the storage pool.

② Before capacity expansion, check whether the main memory cache ratio meets the capacity expansion requirements.

Cache capacity/ (New main storage capacity + Existing main storage capacity) ≥ Main storage cache ratio of the current storage pool

③ The difference between the number of disks on storage nodes in the resource pool cannot be greater than 2.

④ The difference between the number of disks on each storage node in the resource pool cannot be greater than 30%.

⑤ The CPU, memory, and disk slot distribution of new servers should be consistent.

You are advised to perform inspection and evaluation before capacity expansion and follow the high-risk change process for capacity expansion.
