wreedMH, what sort of issue that you are facing on your HP Blade Server environment ?
What I did was:
1. Perform firmware update on the HP Blade, CNA and also updated the ESXi drivers to the latest October 2015 using HP SPP.
2. Upgrade to the latest VMware ESXi 5.1 Update 3b build number 2323236.
3. Upgrade the latest VMware tools to v10.0.5 after the two above has been completed.
4. Follow VMware KB: Large packet loss at the guest OS level on the VMXNET3 vNIC in ESXiSmall Rx Buffers = 8192 andRx Ring #1 Size = 4096
Hope that helps.
