when I come to connfigure oceanstor 2600 v5 file system in eDesinger, 

I saw one field called:

file size: A) 64KB  B) 128KB   C)256KB   D)512KB 


I want to undersand why we have these such sizes? and why it cannot go beyond 512KB ?

are theses sized limited by the NAS system or by user?

for examble: if iam an end user and I had this storage, and I want to upload one movie with 2GB to that NAS storage, what's will happen in uploading ? where theses sizes will play ?

Hello, friend!

The file size indicates the average size of a large file in the actual file size distribution range.

If there are many large files in the actual application environment, for example, several GB large files, select a larger one based on the average size of the most common files.

If the file size is 64 KB to 512 KB, the same is true. If the file size is generally large, choose the larger file.

eDesigner is a capability evaluation tool. The preceding figure shows the service model. The file size corresponds to the block size on the storage device.

The concept is the same. The configuration is based on the size of the file that appears most frequently.

The storage system divides files into blocks. If the block size is proper, the number of blocks is small, which improves the performance.

If 2 GB large files are generated on average, 64 KB blocks are much less than 4 KB blocks, and therefore the performance is much higher.

If the average size of files is 1 KB, select 4 KB blocks.

Hope can help you!

When you say 64KB, do you mean block size?
