Abstract
A data storage network is provided. The network includes a client connected to the data storage network; a plurality nodes on the data storage network, wherein each data node has two or more RAID controllers, wherein a first RAID controller of a first node is configured to receive a data storage request from the client and to generate RAID parity data on a data set received from the client, and to store all of the generated RAID parity data on a single node of the plurality of nodes.
Claims13
An apparatus comprising:
- a first processor coupled to a first storage device, the first processor being configured to:
- in response to receiving a request to store data, writing the data to the first storage device of a first redundant array of redundant nodes (RARN) node of a RARN network, each RARN node of the RARN network comprising one or more processors, RAID controllers, and storage devices;
- generate redundancy data corresponding to the data written to the first storage device;
- distribute the redundancy data to a second storage device in the RARN node of the RARN network, wherein
- at least a portion of the redundancy data is written to the second storage device for failover capability.
