Hello

To create a iSCSI network for 32 hosts, what is the best option??

Without having a vDS and is a better management, is other advantage??

Or should I create a normal Standard Switch for 2 nics to use iSCSI and port bidding.

What is the best option for ESXi 5.0.x and vCenter 5.0.x

Thanks

SL

Hello,

I know your great article.

But it doesn’t answer the question. Is vDS better? Because I can create all configuration also in a vDS and for 32 hosts is much better to manage.

But if someone explain that Standard Switch have more advantages, I will go for that type of vSwitch.

Thanks for your reply.

vDS can be easier to manage, and more complicated to setup, and requires Enterprise Plus, especially if you have many hosts.

First, it simplifies datacenter setup and administration by centralizing network configuration. For example, adding a new host to a cluster and making it vMotion compatible is much easier.
   
Also, distributed ports migrate with their clients. So, when you migrate a virtual machine with vMotion, the distributed port statistics and policies move with the virtual machine, thus simplifying debugging and troubleshooting.
   
And, enterprise networking vendors can provide proprietary networking interfaces to monitor, control and manage virtual networks.

Hi SL,

Using a VDS will be preferred in your case. Once all your 32 host are joined to the Vcenter, you can create the vSwitch once and migrate the host's NIC over. You can also create the PortGroup once and it can be used for all your hosts.

Do note, for each NIC connection to your iSCSI network, you will need 1 portgroup. this way you can fully utilized all your nics as active link without any of them on standby.
