5.2 BeeGFS Usable Space Calculation
Estimated usable space is calculated in TiB (since most tools show usable space in binary units) using the
following formula:
BeeGFS Usable Space in TiB= (0.99* # of Drives* size in TB * (10^12/2^40)
In this formula, 0.99 is the factor arrived at by assuming conservatively that there is a 1% overhead from the
file system. For arriving at the number of drives for storage, 12 drives from the MDS are also included. This is
because, in the MDS, the 12 drives in NUMA zone 0 are used for metadata and the 12 drives in the NUMA
zone 1 are used for storage. The last factor in the formula 10^12/2^40 is to convert the usable space from TB
to TiB.
5.3 Scalable Configurations
The BeeGFS High Performance Storage Solution has been designed to be flexible and you can easily and
seamlessly scale performance and capacity by adding additional servers.
