OceanStor 9000 strip sizes and whether they are different

7

The value of the strip size parameter affects performance and disk utilization. OceanStor 9000 V100R001C01 only supports 16 KB, 32 KB, and 128 KB. The difference among the three is the size of each data slice. Larger strip size value will ensure a higher performance.
The recommended strip sizes are as follows:
- When the average file size is smaller than 64 KB, set the strip size to 16 KB.
- When the average file size is larger than 64 KB but smaller than 512 KB, set the strip size to 32 KB.
- When the average file size is larger than 512 KB, set the strip size to 128 KB.

Relationships between redundancy ratio, strip size, and read/write performance of OceanStor 9000
Relationships between redundancy ratio, strip size, and read/write performance of OceanStor 9000: The redundancy ratio and strip size of OceanStor 9000 directly impact on the storage space utilization. The strip size determines the data slice size. The data slice size is set based on the average size of files in actual services to prevent improper data slices due to a too large strip size, avoiding space waste. Particularly for small files, small strips of 16 KB are needed. The redundancy ratio determines the number of verification data copies and directly impacts on the storage space utilization. For the N+M redundancy ratio in the Erasure Code algorithm, M can be 1, 2, 3, or 4. A larger value of M indicates poorer algorithm performance and more complex computing. N can be 3 to 16. A larger value of N indicates higher algorithm performance and more disks concurrently read/written.
