Since Luster is particularly geared towards high performance and is under a free license, it is often used in the field of supercomputers . 15 of the TOP30 supercomputers are currently using the Luster file system, including what was once the world's fastest TOP500 supercomputer, the Titan .

Luster file systems are scalable and support several thousand client systems, several petabytes (PB) of storage space and hundreds of gigabytes per second (GB / s) of bundled read / write load. This makes Luster a popular choice for e.g. B. large data centers such as Internet service providers , financial service providers or for the oil and gas industry.

With Linux kernel 4.17, Luster was removed from the staging area of ​​the kernel after it was not possible to introduce significant quality improvements into the kernel. As in some cases before, further development now takes place outside the kernel.
