BeeGFS on NetApp with E-Series Storage

Recommended storage pool overprovisioning percentages

Contributors netapp-jsnyder netapp-jolieg

When following the standard four volumes per storage pool configuration for second generation building blocks, refer to the following table.

This table provides recommended percentages to use as the volume size in the eseries_storage_pool_configuration for each BeeGFS metadata or storage target:

Drive size Size

1.92TB

18

3.84TB

21.5

7.68TB

22.5

15.3TB

24

Note The above guidance does not apply to the storage pool containing the management service, which should reduce the sizes above by .25% to allocate 1% of the storage pool for management data.

To understand how these values were determined, see TR-4800: Appendix A: Understanding SSD endurance and overprovisioning.
