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. A data storage network comprising:
a client connected to the data storage network;
a plurality of nodes on the data storage network, wherein each 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.
2. The data storage network of claim 1 , wherein each node further comprises two or more motherboards.
3. The data storage network of claim 1 , wherein the first RAID controller comprises a SAS RAID controller.
4. The data storage network of claim 1 , wherein each RAID controller is located on a separate application blade, wherein each application blade is coupled to a storage device.
5. The data storage network of claim 1 , wherein each node further comprises a plurality of storage devices.
6. 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 a first storage unit;
a second switch coupled to the second RAID controller and to the first storage unit;
a third SAS switch coupled between the first switch and the first RAID controller, wherein the first RAID controller is configured to receive a data storage request and to write data to the first storage unit based on the data storage request.
7. The data storage system of claim 6 , further comprising a fourth SAS switch coupled between the second switch and the second RAID controller.
8. 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 a first storage unit;
a second switch coupled to the second RAID controller and to the first storage unit;
a third SAS switch coupled between the first RAID controller and the first motherboard, wherein the first RAID controller is configured to receive a data storage request and to write data to the first storage unit based on the data storage request.
9. The data storage system of claim 8 , further comprising a fourth SAS switch coupled between the first RAID controller and the first motherboard.
10. The data storage system of claim 8 , wherein the third SAS switch comprises a cluster initiator/targets.
11. 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 a first storage unit;
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 and to write data to the first storage unit 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 a second storage unit;
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 and to write data to the first storage unit based on the data storage request.
