Clustered storage network
View Patent ↗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.
1. 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.
2. The apparatus of claim 1 , wherein:
the first RARN node comprises a first processor configured to:
receive the request to store data; and
cause a first RAID controller of the first RARN node to write the data to the first storage device.
3. The apparatus of claim 2 , wherein the first RAID controller of the first RARN node is further configured to distribute the redundancy data to a third storage device of the first RARN node.
4. The apparatus of claim 3 , wherein at least a portion of the redundancy data distributed to the third storage device is written to the third storage device for failover capability.
5. The apparatus of claim 2 , wherein the request to store data is received from a client connected to the RARN network.
6. The apparatus of claim 2 , wherein the first node comprises first and second Ethernet network interface cards.
7. The apparatus of claim 2 , where the first RAID controller comprises a serial attached SCSI (SAS) RAID controller.
8. A method comprising:
in response to receiving a request to store data, writing the data to a 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;
generating redundancy data corresponding to the data written to the first storage device;
distributing the redundancy data to a second storage device of the first 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.
9. The method of claim 8 , wherein the first RARN node comprises a first processor configured to:
receive the request to store data; and
cause a first RAID controller of the first RARN node to write the data to the first storage device.
10. The method of claim 9 , wherein the first RAID controller of the first RARN node is further configured to distribute the redundancy data to a third storage device of the RARN node.
11. The method of claim 10 , wherein at least a portion of the redundancy data distributed to the third storage device is written to the third storage device for failover capability.
12. The method of claim 9 , wherein the first node comprises first and second Ethernet network interface cards.
13. The method of claim 9 , wherein the first RAID controller comprises a serial attached SCSI (SAS) RAID controller.
