OneFS distributed file system

One distinctive characteristic of OneFS is that metadata is spread throughout the nodes in a homogeneous fashion. There are no dedicated metadata servers. The only piece of metadata that is replicated on every node is the address list of root btree blocks of the inode mapping structure. Everything

All data structures in the OneFS file system maintain their own protection information. This means in the same filesystem, one file may be protected at +1 (basic parity protection) while another may be protected at +4 (resilient to four failures) while yet another file may be protected at 2x
335:); this feature is referred to as FlexProtect. FlexProtect is also responsible for automatically rebuilding the data in the event of a failure. The protection levels available are based on the number of nodes in the cluster and follow the 394:
The nodes that comprise a OneFS System must be connected by a high performance, low-latency back-end network for optimal performance. OneFS 1.0-3.0 used Gigabit Ethernet as that back-end network. Starting with OneFS 3.5, Isilon offered

Encoding is per-directory entry, not per-filesystem. So multiple encodings may be used in a single volume. UTF-8 is encouraged as normative.
1228: 1203: 987: 686: 367:. The native block size is 8192 bytes; inodes are 512 bytes on disk (for disks with 512 byte sectors) or 8KB (for disks with 4KB sectors). 2460: 1935: 729: 2450: 1621: 1430: 339:. Blocks for an individual file are spread across the nodes. This allows entire nodes to fail without losing access to any data.
