Method and system for data integrity
View Patent ↗A device having a storage location for receiving an original data and a corresponding original error correction code (ECC) is provided. The device includes ECC modification pattern generator logic for comparing modified data and the original data for generating a pattern for modifying the original ECC and ECC modification logic for modifying the original ECC based on the pattern.
1. A machine implemented method, comprising:
a network device receiving original data and corresponding original error correction code (ECC) at a receive segment of a port of the network device;
comparing modified data and the original data using an exclusive OR function for generating a pattern for modifying the original ECC; wherein the original data is modified by modifying a priority level of the original data and the generated pattern comprises syndrome bits derived from an output of the exclusive OR function; and
modifying the original ECC based on the pattern to create a modified ECC, without having to regenerate the original ECC and transmitting the modified ECC with the modified data via a transmit segment of the port.
2. The method of claim 1 , wherein the network device is a switch element having a plurality of ports.
3. The method of claim 2 , wherein at least one of the plurality of ports of the switch element is configured to operate as a Fibre Channel port.
4. The method of claim 2 , wherein at least one of the plurality of ports of the switch element is configured to operate as an Ethernet port.
5. The method of claim 2 , wherein at least one of the plurality of ports of the switch element is configured to operate as a Fibre Channel over Ethernet port.
6. The method of claim 1 , wherein the network device is an adapter.
7. The method of claim 1 , wherein data modification logic modifies the original data based on a data modifier.
8. The method of claim 1 , wherein ECC modification pattern generator logic compares the original data and the modified data.
9. A device, comprising:
a network port with a receive segment for receiving an original data and a corresponding original error correction code (ECC);
an ECC modification pattern generator logic for comparing modified data and the original data using an exclusive OR function for generating a pattern for modifying the original ECC; wherein the original data is modified by modifying a priority level of the original data and the generated pattern comprises syndrome bits derived from an output of the exclusive OR function; and
an ECC modification logic for modifying the original ECC based on the pattern, without having to regenerate the original ECC.
10. The device of claim 9 , wherein the device comprises a switch element having a plurality of ports.
11. The device of claim 10 , wherein at least one of the plurality of ports of the switch element is configured to operate as a Fibre Channel port.
12. The device of claim 10 , wherein at least one of the plurality of ports of the switch element is configured to operate as an Ethernet port.
13. The device of claim 10 , wherein at least one of the plurality of ports of the switch element is configured to operate as a Fibre Channel over Ethernet port.
14. The device of claim 9 , wherein the device is an adapter.
15. The device of claim 9 , wherein a data modification logic modifies the original data based on a data modifier.
16. A machine implemented method for a network device, comprising:
receiving original data and corresponding original error correction code (ECC) by a receive segment of a port of the network device;
providing a data modifier to a data modification logic indicating a modification type for modifying the received original data, where the data modifier indicates modifying a priority level for the received original data;
modifying the original data based on the data modifier to create a modified data;
comparing the modified data and the original data using an exclusive OR function for generating a pattern for modifying the original ECC;
modifying the original ECC based on the pattern without having to regenerate the original ECC, wherein the pattern comprises syndrome bits derived from an output of the exclusive OR function; and
transmitting the modified data and the modified ECC to a destination via a transmit segment of the network device.
17. The method of claim 16 , wherein the network device is a switch element having a plurality of ports.
18. The method of claim 17 , wherein at least one of the plurality of ports of the switch element is configured to operate as a Fibre Channel port or as an Ethernet port.
19. The method of claim 17 , wherein at least one of the plurality of ports of the switch element is configured to operate as a Fibre Channel over Ethernet port.
20. The method of claim 16 , wherein the device comprises an adapter.
