Is there a protection against multiple concurrent dump creation? Do we need one?


About SSD storage

There are several important points to consider when writing data to SSD storage

  • Random writes will perform just as well as sequential writes if writes are multiple of and aligned to the size of a clustered block.
  • Many concurrent small write requests will offer a better throughput than a single small write request.
  • A single large write request offers the same throughput as many small concurrent writes.

Typical throughput versus write block size chart will look like this.

One of the configuration aims is to find minimum block size when random and sequential writes show the same throughput.
