    @Zaid-md ,

    I hope all is well. VMware networking as a topic can be a bit complex, but at the same time, it is very similar in many respects to what a non-virtualized network architecture would look and operate like.

    I would suggest the following in the order I am listing them as a good plan for you to get a basic understanding:

    Take a look at the CompTIA Network+ course in our library to establish a good basic understanding of networking and the concepts that govern it, irrespective of virtualization.

    Take a look at the following resource from VMware:

    https://www.vmware.com/learn/49682_REG.html?touch=1&src=ps_5e67990beb873&cid=7012H000000wj1M&gclid=02025779e96a11ab868f3701c29aa231&gclsrc=3p.ds&msclkid=02025779e96a11ab868f3701c29aa231

    Take a look at the VMware DCV-VCP 7 course in our library to gain a refined level of understanding specific to the VMware environment(s) that you are likely to come across and interact with.

    Good Luck !!!

    Cheers,

    Adam

    Perry,

    You have a couple of choices. If it is a NAS, you absolutely want to use a dedicated NIC for connectivity.

    The main reason is you do not want storage traffic competing with regular network traffic. The other reason, is that you will want to enable Jumbo Frames on the storage network, and not your normal LAN.

    The other reason you want a dedicated NIC is that you can by hardware accelerated NICs specifically designed for iSCSI traffic. It is usually referred to as iSCSI Offload. These NICs can have a noticeable impact on the TCP/IP overhead imposed by moving SCSI traffic over IP.

    All that being said, you don't want to use a network adapter for storage on production systems. The performance just isn't there. It is always better to go with Fiber Host Bus Adapters (HBAs) and connect to your SAN via fiber. When that isn't an option, NICs with iSCSI Offload combined with Jumbo Frames can get you pretty decent performance.

    Hope that helps,
