What ports need to be connected from emc cx4 iSCSI

What ports need to be connected to stand alone switch from a emc cx4 to isolate Iscsi ( SPa, spb Iscsi ports, management interface?
If I add esx host with two nics for Iscsi do I need Console port as well connected to the switch  exx 4.0?
Do I need a trunk uplink tomy LAN switch?

What configuration needs to be done on ports on the isolated Iscsi cisco switch?

How many NICs are you planning to have in the ESX host ?

I have 8 nics on ESX host.
Two will be for ISCSI.

You will only need to connect the iSCSI ports on each SP to your switch.  Here's an article I wrote about creating a simple iSCSI connection on ESX.

http://www.experts-exchange.com/Software/VMWare/A_3720-Simple-iSCSI-Configuration-Guide-for-VMware-ESX.html

You will not need to create a console connection on the iSCSI vSwitch under ESX 4.x, that was a requirement for earlier versions.

iSCSI Networking may be setup with multiple options, the first option can be with a single vSwitch with all the 8 NICs in Active Adapters configuration and using Port Groups to segregate the Mgmt, VM and VMKernel traffic.

The second option would be to create 4 vSwitches, one for Mgmt with 2 NICs in Active Adapters config, one for VM traffic, one for iSCSI traffic and one for VMotion.

Does the EMC SAN management ports need access to the Iscsi ports?
Do I need to trunk from Iscsi switch to LAN?

Do I eanble port fast on switch?
Do I enable jumbo frams?

If so what is config for Cisco switch?

Thanks

I may be in a better position to guide you if you can explain your whole VMware setup clearly (Total number of Hosts in the cluster, inter-connectivity between switches and esx hosts, whether there would be redundant paths to the SAN,etc).

The EMC management ports do not need connectivity to the iSCSI ports.  You *can* trunk the ports but it is not necessary as ESX will not fully support active LACP.

I would enable port fast and jumbo frames on the switch, though keep in mind you must also enable jumbo frames on the vmknic, vSwitch, and SAN for it to be effective.

Wonderful, I am very thankfull for your quick response and I have one more request.

Is there a config document for the jumbo fram that gives detail config for cisco switch , Vmware vmknic , vswitch and Emc San cx 4?
