- In the table, the maximum IOPS and maximum bandwidth all include both the read and write operations. So, maximum IOPS = read IOPS + write IOPS.
- The minimum expansion increment of SFS Turbo Standard-Enhanced (discontinued), Standard, Performance-Enhanced (discontinued), and Performance file systems is 100 GB. The minimum expansion increment of 20 MB/s/TiB, 40 MB/s/TiB, 125 MB/s/TiB, 250 MB/s/TiB, 500 MB/s/TiB, or 1,000 MB/s/TiB file systems is 1.2 TB, and the new capacity must be an integral multiple of 1.2.
