Abstract

The disclosure is directed to protecting data of a scalable storage system. A scalable storage system includes a plurality of nodes, each of the nodes having directly-attached storage (DAS), such as one or more hard-disk drives and/or solid-state disk drives. The nodes are coupled via an inter-node communication network, and a substantial entirety of the DAS is globally accessible by each of the nodes. The DAS is protected utilizing intra-node protection to keep data stored in the DAS reliable and globally accessible in presence of a failure within one of the nodes. The DAS is further protected utilizing inter-node protection to keep data stored in the DAS reliable and globally accessible if at least one of the nodes fails.

First claim

What is claimed is:

1. A storage system, comprising:
a plurality of processing nodes in communication with one another, each processing node including:
a plurality of disks local to a respective processing node;
at least one host, the at least one host configured to write data to a first selected disk of the plurality of disks;
a local redundancy computation unit configured to determine local redundant data utilizing the data written to the first selected disk by the at least…
