Abstract

A software suite, a method and a system of configuring hosts of a secondary data storage and recovery system are disclosed. In an embodiment, a system includes hosts saving data in primary storage devices, a software suite to provide secondary storage and a recovery service to one or more networked node includes a portion to configure at least one network node to perform a service, a portion to order a service and to generate metadata about data generated to store in secondary storage using a processor and a non-volatile memory, and a portion to perform data write validation and a portion to receive and prepare data to store in secondary storage. The portion to perform service configuration, the portion to perform ordering, and the portion to perform metadata generation are part of a client instance may be provided one instance per to the one or more networked node.

Claims

1. In a system comprising hosts saving data in primary storage devices, a software suite to provide secondary storage and a recovery service to at least one networked node comprising:

a portion to configure at least one network node to perform a service;

a portion to order a service and to generate metadata about data generated to store in secondary storage using a processor and a non-volatile memory;

a portion to perform data write validation to prevent redundant writes in the secondary storage, wherein the metadata is used to validate data write through at least a metadata comparison via a processor;

a portion to receive and prepare data to store in secondary storage; and

a data splitter coupled to a data path from a host to the primary storage device to provide a copy of a data written from the host to the primary storage via the data path to the secondary storage in near real time through transparently splitting off data from the host to a primary storage device,

wherein the copy of a data written from the host to the primary storage is provided to the secondary storage through a storage and recovery server to enhance the secondary storage and recovery service,

wherein the server to provide a data storage for host to a secondary storage in a continuous streaming mode, and

wherein a portion of the server application comprises firmware installed on a field programmable gate array (FPGA) supported by a line card, and wherein the firmware includes a frame rate detection engine to adjust performance of the line card to an actual frame rate of data being received on the line card.

2. The software suite of claim 1 wherein the portion to perform service configuration, the portion to perform ordering, and the portion to perform metadata generation are part of a client instance provided one instance per to the at least one networked node.

3. The software suite of claim 1 wherein the portion to receive data, the portion to validate data, and the portion to store the data are part of the server application provided to a hardware host connected to a secondary storage medium and to an interface to the at least one networked node.

4. The software suite of claim 3 wherein the hardware host is at least one of a PC and a dedicated server box.

5. The software suite of claim 1 wherein the portion to prepare the data to store in secondary storage controls a cache memory system in a hardware host.

6. The software suite of claim 1 wherein the portion to perform data validation and the portion to prepare data to store in secondary storage include a data table search utility and a data compression utility coupled with a sparse file utility.

7. The software suite of claim 3 wherein the server application is comprised of server software and line card-based software.

8. The software suite of claim 1 wherein the portion to generate metadata is generated is part of a server application provided to a hardware host connected to a secondary storage medium and to an interface to the at least one networked node.

9. The software suite of claim 1 wherein once the received data has been stored in secondary storage, the received data is viewable as volume block data, file system data, and application level data.

10. The software suite of claim 1 wherein the portion to prepare the received data to store in secondary storage stores data changes as a distinct and time stamped version from other changes to a data block to provide revision selectable and time-based recovery of data.

11. The software suite of claim 1 wherein the data prepared to store in secondary storage is requested over at least one of an IP connection and across a LAN network as recovery data.

12. The software suite of claim 1 wherein the portion to configure at least one network node to perform a service operates through at least one of a direct connection, a LAN connection, a remote network connection, an intermediate server, and a web interface.

13. The software suite of claim 1 wherein the portion to receive data is comprised of a host activity monitor to track boot and task activity.

14. The software suite of claim 2 wherein an additional metadata generation utility instance is created to generate metadata associated with a separate task occurring within the at least one networked node.

15. The software suite of claim 1 further comprising a portion to communicate with at least one LAN-connected networked node using a LAN communication link.

16. The software suite of claim 1 wherein the portion to receive data receives streaming compressed data to store in secondary storage, and wherein the streaming compressed data is decompressed and rendered by the portion to prepare the received data to be stored in secondary storage.

17. The method, comprising:

configuring at least one network node to perform a service using a portion of a software suite to provide a secondary storage and recovery service to at least one networked node in a system comprising hosts saving data in primary storage devices;

ordering a service and generating metadata about data generated to store in secondary storage using a processor and a non-volatile memory to process a portion of the software suite;

performing data write validation using a portion of the software suite; and

receiving data and to preparing the received data to store in secondary storage using a portion of the software suite; and

transparently splitting off data from the host to a primary storage device through a data splitter coupled to a data path from a host to the primary storage device to provide a copy of a data written from the host to the primary storage via the data path to the secondary storage in near real time,

wherein the copy of a data written from the host to the primary storage is provided to the secondary storage through a storage and recovery server to enhance the secondary storage and recovery service, and

wherein the server to provide a data storage for host to a secondary storage in a continuous streaming mode, and

wherein a portion of the server application comprises firmware installed on a field programmable gate array (FPGA) supported by a line card, and wherein the firmware includes a frame rate detection engine to adjust performance of the line card to an actual frame rate of data being received on the line card.

18. The method of claim 17:

wherein the portion to perform service configuration, the portion to perform ordering, and the portion to perform metadata generation are part of a client instance provided one instance per to the at least one networked node.

19. The system comprising hosts saving data in primary storage devices, further comprising:

at least one network node configurable by a software suite to provide a secondary storage and recovery service;

a client instance provided to the at least one networked node to order a service and to generate metadata about data generated to store in secondary storage using a processor and a non-volatile memory;

a hardware host to operate a portion of a software suite to perform data write validation; and
