E9000 server—LUN was very slow

Hello, werido!

If the LUN read and write speed is very slow, I think you can do as follows to solve your problem:

1. check whether the installed lpfc driver and firmware match the E9000;

2. check for error codes on FC links between the HBA and the storage device;

3. run the iostat command on the host to query the I/O delay and concurrent I/O operations;

4. collect the OS message log and check the lpfc driverinformation and the I/O queue depth configured for the HAB driver;

5. perform drive performance tests (read and write 100 GBand 100 MB files).

If they do not work, you can contact our enginners here:
