Is your shared storage on a different subnet?  Is this for production or lab?

Sir, Thank you vey much for the replyt. let me explain the design.
Procured or available infrastructure:
Have 2 servers HP DL380G5 with 48gb ram and 4 physical nics and two processor
Dell R710 with two processors, 48gb ram and 4 physical nics.
EMC storage vnxe3100.
Vmware essential plus

Requirement:
04 VMs for each server but the vms will be housed in the storage this is because to acheive HA , in this all guest's will be of linux only two will be of windows.

For now installed ESXi5.0 on thumb drive for the dell server raid configured for this server is RAID10 and RAID1 for the total 06 disks of 300gb with this i got 2 virtual disks or luns in that on one LUN created the datastore with the VMS file system and installed on ubuntu guest and vcenter server appliance still the EMC device is not yet configured planning to setup one more ubuntu server and give it for the production later once the EMC storage Vnxe3100 is configured then using the vmotion will migrate the vms from the dell server to the storage. for doing all this iam looking for how to configure the vswitch and vmports and best practices or best design please help.

OK.  Since you only have 4 nics in the DL380 G5s I would do the following:

Create at least two VLANs.  

1.  VLAN 1 PRODUCTION (Virtual Machines) - routable
2   VLAN 2 SAN - non routbale

on the DL380 G5.

2 vswitches

vswitch 0 - management console - 2 nics teamed but no etherchannel
vswitch 0 - vmk1 - vmkernel - for vmotion, on the same production vlan as the ESXi host
(2 port groups)

vswitch 1 - SAN
- Create  a vswitch with 2 nics, see url

http://blogs.vmware.com/vsphere/2011/08/vsphere-50-storage-features-part-12-iscsi-multipathing-enhancements.html



On the VNXe you can map the datastore direclty from the SAN and manage.

Going forward you can get another 2 or 4 port nic card and offload the vmotion to a separate set of nics, with vsphere 5 you can use more hat one nic for vmotino

Sir, Thanks for the reply, as of now not used the vlan as physical switches are not configured for the vlan, please find the attached print screen of the configuration. I have done nic teaming for vswitch 0 and  for the vswitch1. please suggest me is it like this. Please help.

I would put the VM Network on vswtich 0 and create a separate vswitch for vswitch 1.  I would then put the EMC and the nics attached to vswitch 1 on a separate physical switch.  Putting iscsi traffice on your production network can cause major problems.

You would take the management from the SAN and put on you production network for management but the two ports on each controller should go onto a separate switch.  Also ensure that all your ports are 1GB

Sir, thanks for the reply. in vswitch 0 machine port group and vm kernel port , vms are added to the machine port group.

2. created vswitch1 and created vmkernel por with nic teaming for the EMC storge.
attached print screen request you to please suggest.

You're slowly getting there.

Put the vmkernel for SAN on a different switch AND different subnet.

The switch for the SAN and vmkernel ports coming from ESX hosts should be standalone, not attached to the other switches unless you can segregate by vlan which you stated you is not supported.

Sir, or is it recommended to create the vmk1 on vswitch1 and establish the connection to the EMC storage from here.

And on vswitch0 add VMS .

please suggest.

Sir, my previous post is done before seeing your last two posts.
Iam sorry, EMC storage will be connected to the vmk1 on switch1.
All the vms will be added to the vswitch0.
Please suggest me.

For the EMC you would have to put the controllers on one switch since you have two switches and they don't support VLANs, trunking, etc..

I would put all your SAN gear on the one switch and the Production VLAN ports on the other one.  Going forward you should plan on getting better switches that can give you VLANs and port monitoring.
