| Allocation workgroup storage is available on a [[abstract:darwin:filesystems:lustre|high-performance Lustre-based filesystem]] having almost 1.1 PB of usable space. Users should have a basic understanding of the concepts of [[abstract:darwin:filesystems:lustre|Lustre]] to take full advantage of this filesystem. | Allocation workgroup storage is available on a [[abstract:darwin:filesystems:lustre|high-performance Lustre-based filesystem]] having almost 1.1 PB of usable space. Users should have a basic understanding of the concepts of [[abstract:darwin:filesystems:lustre|Lustre]] to take full advantage of this filesystem. The default stripe count is set to 1 and the default striping is a single stripe distributed across all available OSTs on Lustre. See [[https://www.nas.nasa.gov/hecc/support/kb/lustre-best-practices_226.html|Lustre Best Practices]] from Nasa. |
