	~~==== Using Fibre Channel ====~~

	~~Setting up a datastore in VMware using fibre channel takes just a few simple steps.~~

	*First verify that the fibre channel ports are enabled from within QuantaStor. You can enable them by right clicking on the port and selecting 'Enable FC Target Mode...'.

	~~[[File:Enable Fibre Chnl Target Mode.jpg\|900px]]~~

	*Create a host entry within QuantaStor, and add all of the WWNs for the fibre channel adapters. To add more than one initiator to the QuantaStor host entry, right click on the host and select 'Add Initiator'. The WNNs can be found in the 'Configuration' tab, under the 'Storage Adapters' section.

	~~[[File:VmwareStorageAdapters.png\|800px]]~~

	*Now add the desired storage volume to the host you just created. This storage volume will be the Datastore that is within VMware.

	*Next, navigate to the 'Storage' section of the 'Configuration' tab. From within here we will want to select 'Rescan All...'. In the rescan window that pops up, make sure that 'Scan for New Storage Devices' is selected and click 'OK'.

	~~[[File:VmwareRescanAll.png\|800px]]~~

	*After the scan is finished (you can see the progress of the task at the bottom of the screen), select the 'Add Storage...' option. Make sure that 'Disk/LUN' is selected and click next. If everything is configured correctly you should now see the storage volume that was assigned before. Select the storage volume and finish the wizard.

	~~You should now be able to use the storage volume that was assigned from within QuantaStor as a datastore on the VMware server.~~

 The VMware EUI unique identifier for any given volume can be found in the properties page for the Storage Volume in the QuantaStor web management interface.  There is also a column you can activate as shown in this screenshot.

			These configuration options are workload dependent and may not yield improvements.

			Here one can see that vmnic2 has a max RX/TX size of 1024:
			<pre>
	esxcli network nic ring preset get -n vmnic2		esxcli network nic ring preset get -n vmnic2
	RX: 1024		RX: 1024
Line 130:		Line 134:
	RX Jumbo: 0		RX Jumbo: 0
	TX: 1024		TX: 1024
			</pre>

			This may be increased to 2048 using the following commands for RX and TX respectively:
			<pre>
	esxcli network nic ring current set -n vmnic2 -r 2048		esxcli network nic ring current set -n vmnic2 -r 2048
	esxcli network nic ring current set -n vmnic2 -t 2048		esxcli network nic ring current set -n vmnic2 -t 2048
	~~esxcli network nic ring current set -n vmnic3 -t 2048~~		</pre>
	~~esxcli network nic ring current set -n vmnic3 -r 2048~~

			Then verify the configuration changes after the adjustments:
			<pre>
	esxcli network nic ring preset get -n vmnic2		esxcli network nic ring preset get -n vmnic2
	RX: 2048		RX: 2048
Line 141:		Line 149:
	RX Jumbo: 0		RX Jumbo: 0
	TX: 2048		TX: 2048

	There are special cases where it can be helpful with specific models of network cards (NICs) to set the Jumbo Frames MTU to something other than 9000. If you're not seeing any improvement with a Jumbo Frame size of 9000 you might try some alternate sizes (eg ~~9020~~, 8500, 4800, 4200) but in general one should ~~set it to~~ 9000 which is the standard for Jumbo Frames.
