HP NIC Teaming, Netapp CIFS, vRanger Pro Issue

I was seeing extremely slow CIFS performance on servers with HP NIC teams. This includes our vRanger backup server. I would map a drive and it would take minutes to come up, etc. I finally found a NOW article suggesting to run:

options ip.fastpath.enable off

This command, from my understanding, will not use cached MAC addresses. Because of the way our HP NIC team is setup, different MACs were being presented and this caused an issue. So far so good.

HP DL380 G6 using Intel X5550 processors


I recently purchased some servers to host our ESX environment for a client. We went with the X5550 processors. Be careful of how you purchase the memory cause the more you buy the slower it is.

Basically the server has 3 channels with 1 CPU and 6 channels with 2 CPUs. Each channel has 3 slots for a total of 18 slots with 2 CPUs. If you populate 1 slot per channel you can run at 1333 MHz. If you put in one more memory chip in a channel, you run at 1066. One more and you go down to 800 MHz.

The 8 GB DIMMs do not run at 1333 so basically if you want to run at that speed you can only have 24 GB of memory. Here is the table:
