Abstract

A system for data storage includes a switch node, a meta-data server, a plurality of storage servers having at least one respective data storage device, and a scalable interconnect. The scalable interconnect couples the switch node, the meta-data server, and the storage servers. At least one of the switch node, the meta-data server and the storage servers includes a hierarchical storage manager (HSM). When information is received at the switch node, the HSM presents the information substantially simultaneously to the storage servers for storage at the respective data storage devices.

Claims

1. A system for data storage, the system comprising:

a switch node;

a meta-data server;

a plurality of storage servers having at least one respective data storage device; and

a scalable interconnect to couple the switch node, the meta-data server, and the storage servers, wherein at least one of the switch node, the meta-data server and the storage servers includes a hierarchical storage manager (HSM), and when information is received at the switch node, the HSM presents the information substantially simultaneously to the storage servers for storage at the respective data storage devices and the information is deleted from the storage devices after respective predetermined time durations, wherein the storage capacity of the storage devices is predetermined to an amount of data expected to be stored by a user during the respective predetermined time duration, and the storage capacity of each successively increasing time duration storage device is within a preferred range of twice the size to fifty times the size of the previous time duration storage device, and a most preferred range of five times the size to twenty-five times the size of the previous time duration storage device.

2. The system according to claim 1 wherein the switch node is a network attached storage (NAS) switch node.

3. The system according to claim 1 further comprising at least one client coupled to the switch node, and the at least one client presents the information to the switch node.

4. The system according to claim 1 wherein the system is an object-based data storage system.

5. The system according to claim 1 wherein the storage servers are performance and archive storage servers.

6. The system according to claim 1 wherein the storage capacity of each successively increasing time duration storage device is about ten times the size of the previous time duration storage device.

7. A method of managing data storage, the method comprising:

interconnecting a switch node, a meta-data server, and a plurality of storage servers having at least one respective data storage device using a scalable interconnect;

presenting information substantially simultaneously to the storage servers for storage at the respective data storage devices using a hierarchical storage manager (HSM) when the information is received at the switch node; and

deleting the information from the storage devices after respective predetermined time durations, wherein the storage capacity of the storage devices is predetermined to an amount of data expected to be stored by a user during the respective predetermined time duration, and the storage capacity of each successively increasing time duration storage device is within a preferred range of twice the size to fifty times the size of the previous time duration storage device, and a most preferred range of five times the size to twenty-five times the size of the previous time duration storage device.

8. The method according to claim 7 the wherein the switch node is a network attached storage (NAS) switch node.

9. The method according to claim 7 further comprising coupling at least one client to the switch node, and the at least one client presents the information to the switch node.

10. The method according to claim 7 wherein the HSM, the storage servers and the data storage devices comprise an object-based data storage system.

11. The method according to claim 7 wherein the storage servers are performance and archive storage servers.

12. The method according to claim 7 wherein the storage capacity of each successively increasing time duration storage device is about ten times the size of the previous time duration storage device.

13. For use in a data storage system, a hierarchical storage manager (HSM), the manager comprising:

a processor; and

a memory, wherein the memory includes programming to perform the steps of;

interconnecting a switch node, a meta-data server, and a plurality of storage servers having at least one respective data storage device using a scalable interconnect;

presenting information substantially simultaneously to the storage servers for storage at the respective data storage devices using a hierarchical storage manager (HSM) when the information is received at the switch node; and

deleting the information from the storage devices after respective predetermined time durations, wherein the storage capacity of the storage devices is predetermined to an amount of data expected to be stored by a user during the respective predetermined time duration, and the storage capacity of each successively increasing time duration storage device is within a preferred range of twice the size to fifty times the size of the previous time duration storage device, and a most preferred range of five times the size to twenty-five times the size of the previous time duration storage device.

14. The manager according to claim 13 wherein the information is deleted from the storage devices after respective predetermined time durations.
