Abstract

A method comprising the steps of (A) generating a call for a first operating system at a host, (B) sending the call for the first operating system from the host to a storage array over a network, (C) generating a response to the call for the first operating system from the host, (D) sending the response from the storage array to the host over the network and (E) capturing and storing the response in a device.

Claims

1. A method for testing a storage management software across different operating systems, the method comprising:

generating, by said storage management software, a first symbol call for a first operating system at a host;

sending said first symbol call for said first operating system from said host to a storage array over a network, wherein said network comprises a fibre channel network;

generating, by said storage array, a first symbol response to said first symbol call for said first operating system from said host;

sending said first symbol response from said storage array to a device over said network;

capturing and storing said first symbol response in said device;

sending said first symbol response from said device to said host over said network;

generating, by said storage management software, a second symbol call for a second operating system at said host, the second operating system being different from the first operating system;

sending said second symbol call for said second operating system to said device; and

sending said first symbol response from said device to said host in response to receiving said second symbol call for said second operating system without providing additional storage arrays for testing said second symbol call for said second operating system.

2. The method according to claim 1, wherein said device is configured to publish a universal transport mechanism Logical Unit Number (LUN).

3. The method according to claim 1, wherein said storage array comprises one or more solid state storage devices.

4. The method according to claim 1, wherein said host comprises a hardware device having installed thereon the storage management software.

5. The method according to claim 1, wherein said first symbol call for said first operating system is encoded in a fibre channel frame packet.

6. The method according to claim 1, wherein said capturing and storing further comprises:

storing an object graph of said first symbol call for said first operating system.

7. A system for testing a storage management software across different operating systems, the system comprising:

a host comprising a processor and a memory accessible by the processor, the host generating, by said storage management software, a first symbol call for a first operating system and sending said first symbol call for said first operating system to a storage array over a network, wherein said network comprises a fibre channel network;

said storage array receiving said first symbol call for said first operating system, generating a first symbol response to said first symbol call for said first operating system, and sending said first symbol response to said host;

a device capturing said first symbol response sent from said storage array storing said first symbol response, sending said first symbol response to said host,

wherein said host generates, by said storage management software, a second symbol call for a second operating system and sends said second symbol call for said second operating system to said device, the second operating system being different from the first operating system;

said device sending said first symbol response to said host in response to receiving said second symbol call for said second operating system without providing additional storage arrays for testing said second symbol call for said second operating system; and

the fibre channel network connecting said host, said storage array and said device.

8. The system according to claim 7, wherein said host has installed thereon the storage management software.

9. The system according to claim 7, wherein said storage array comprises one or more solid state storage devices.

10. The system according to claim 7, wherein said device comprises a network interface, an analyzer capability, and the memory for storing said first symbol response.

11. The system according to claim 10, wherein said device further stores an object graph of said first symbol call for said first operating system.

12. The system according to claim 7, wherein said host further generates a plurality of symbol calls for said first operating system.

13. The system according to claim 12, wherein said storage array further generates a plurality of symbol responses in response to said plurality of symbol calls for said first operating system.

14. The system according to claim 13, wherein said device further captures and stores said plurality of symbol responses.

15. The system according to claim 7, wherein said first symbol call for said first operating system is encoded in a first fibre channel frame packet.

16. The system according to claim 15, wherein said first symbol response is encoded in a second fibre channel frame packet.
