Data compression

OneFS supports inline data compression and decompression, using both hardware and software approaches depending on the node model.

The F810 node contains a Network Interface Card (NIC) that compresses and decompresses data.

The F810 node contains a 40Gb Ethernet Network Interface Card (NIC), performing hardware compression and decompression.

Compression and decompression are performed in parallel across the NIC interfaces as clients read and write data to the cluster. This distributed interface model allows compression to scale linearly across the node pool as supported nodes are added to a cluster.

You can enable inline data compression on the Dell PowerScale F900 and F600-NVMe and F200 SSD nodes, PowerScale H700/7000 and A300/3000 node, and the Isilon F810 and H5600 platforms.

The following table lists the nodes and OneFS release combinations that support inline data compression.

Table 1. Nodes and Release CombinationsThe following table displays the release combinations for each node.
Nodes	Required OneFS releases
F810	8.1.3 or 8.2.1 and later
F900 nodes	9.2.0.0. and later
H5600 nodes	8.2.0 or 8.2.2 and later
H700, H7000 nodes	9.2.1.0 and later
F200, F600 nodes	9.0.0.0 and later
A300, A3000 nodes	9.2.1.0 and later
P100 and B100 accelerator nodes	9.3.0.0 and later

Mixed Clusters

In a mixed cluster environment, data is stored in a compressed form on F810, H5600, F200, and F600 node pools. Data that is written or tiered to storage pools of other node types is uncompressed when it moves between pools.
