I need some help on what VSAN's are and if possible an example.
I did find few articles on the internet, but couldn't understand it to my liking.
It could be really useful if anyone could explain it to me in layman terms.
Not sure whether you have already received the required information you were looking for. However, since there was no reply to this thread here, my little effort to help you out.
Are you referring to VSAN in terms of Cisco Switches? Typically, VSAN will be meant for Virtual SAN - and if you are familiar with VLAN (Virtual LAN) fundamentals - it is very similar to it. VSAN was designed by Cisco modeled after their VLAN concept - but later it has been widely used and deployed in a complex SAN technology.
In a Storage Area Network - where all devices are interconnected in a switched (fabric) environment, you may create a virtual fabric out of the same physical SAN - the devices in a VSAN will be restricted to see and talk to the other devices in the same VSAN.
By definition, A virtual storage area network (VSAN) is a collection of ports from a set of connected Fibre Channel Switches, that form a virtual fabric. Ports within a single switch can be partitioned into multiple VSANs, despite sharing hardware resources. Conversely, multiple switches can join a number of ports to form a single VSAN.
Based on what exactly you are looking for and what you plan on doing - you may find a number of technical documents and manuals from different vendors.
Happy to be of any little help here,
VSAN is something like logical splitting of a physical fabric. It is a collection of ports from a set of connected Fibre Channel switches, that form a virtual fabric.
VSANs are similar in many ways to VLANs. MDS-series switches allow physical switches to be carved into several virtual fabrics called VSANs (Virtual SANS). VSANs have the following features:
When creating VSANs, multiple switches are not required, a VSAN can be created on one switch, however the use of TE_Ports allows VSAN traffic to flow across ISLs in the fabric. VSANS can be created using the CLI, Fabric Manager or Device Manager. The major difference is that with the Fabric Manager GUI is that VSAN can be created on all switches in one step. With the CLI or Device Manager, VSANs must be created in each switch separately.
This information is from the EMC SAN Management course. more information on VSANs can be found in the Advanced SAN Implementation course (for implementers) and the Advanced SAN Design course (for architects) available through the EMC education website http://education.emc.com

VSAN (virtual storage area network) is a collection of ports from a connected Fibre Channel switches, that form a virtual fabric. Ports within a single switch can be partitioned into multiple VSANs, despite sharing hardware resources. Multiple switches can join a number of ports to create a single VSAN. VSANs can also be configured separately and independently.
VSAN is the feature of CISCO MDS Switches, Brocade switches have the same feature called LSAN.
