Strip Size(RAID Settings).
| F.A.Q. • SupportStrip Size(RAID Settings).
- The stripe size determines how data is distributed across the hard drives. It also determines how many disks can be accessed to handle a single I/O request. Stripe size can have a big impact on performance. Typically, sequential workloads benefit from using large stripe sizes (512 KB or 1 MB).
- For random access types, the stripe size depends on the typical access block size and data alignment. For example, if a database uses a record size of 16 KB with an alignment of 16 KB, the optimal stripe size may be 16 KB. For a file server or web server, a large stripe size (512 KB or 1 MB) may be optimal. The software vendor's documentation often provides recommendations for selecting RAID stripe sizes.
Important
- Matching the size of the bar to the size of the file system cluster usually does not give any benefit.
- Usually, the size of the data blocks or files used by the application is more important.
- However, it is not recommended to set the bar size smaller than the cluster size.
