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.
Claims15
A node on a data storage network, comprising:
- two or more RAID controllers, wherein a first RAID controller is configured to receive a data storage request from a 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 the node.
A data storage system comprising:
- a first and second RAID controllers being in communication with each other;
- a first and second motherboards, the first motherboard being coupled to the first RAID controller, and the second motherboard being coupled to the second RAID controller;
- and
- a first switch coupled to the first RAID controller and one or more storage units;
- a second switch coupled to the second RAID controller and to the one or more storage units, wherein the first RAID controller is configured to receive a data storage request, generate RAID parity data on a data set corresponding to the data storage request, store all of the generated RAID parity data across the one or more storage units, and to write data of the data set to at least a first storage unit of the one or more storage units based on the data storage request.

A data storage network comprising:
- a first node comprising:
- a first and second RAID controllers being in communication with each other;
- a first and second motherboards, the first motherboard being coupled to the first RAID controller, and the second motherboard being coupled to the second RAID controller;
- and
- a first switch coupled to the first RAID controller and one or more first storage units;
- a second switch coupled to the second RAID controller and to the first storage unit, wherein the first RAID controller is configured to receive a data storage request, generate RAID parity data on a data set corresponding to the data storage request, store all of the generated RAID parity data across the one or more first storage units of the first node, and to write data to at least one storage unit of the one or more first storage units based on the data storage request;
- and
- a second node comprising:
- a third and fourth RAID controllers being in communication with each other;
- a third and fourth motherboards, the third motherboard being coupled to the third RAID controller, and the fourth motherboard being coupled to the fourth RAID controller;
- and
- a third switch coupled to the third RAID controller and one or more second storage units;
- a fourth switch coupled to the fourth RAID controller and to the second storage unit, wherein the third RAID controller is configured to receive a data storage request, generate RAID parity data on a data set corresponding to the data storage request, store all of the generated RAID parity data across the one or more second storage units of the second node, and to write data to at least one storage unit of the one or more second storage units based on the data storage request.
