Check points
Ensure server's apps run in virtualized env
Ensure we have enough storage & network
Network
vSwitch
Associates the physical NICs in the ESXi hosts to the virtual NICs in VMs
Provide
VM to VM com inside same ESXi
VM to physical network com
VM to VM com across separate ESXi hosts
VMKernel access to physical network
VMotion
iSCSI access
vSphere Replication Traffic
Components
Port / PortGroup
VMKernel Port
connect to storage & VMotion LANs
connect to a management network (ESXi)
require IP
Virtual Machine Port Group
connect VM to production networks
requires Network Label & VLAN ID (optional)
Uplink
connection between vSwitch and physical NIC
can have vSwitch with no uplink

Types
Standard vSwitch
exist within a ESX(i) server
Distributed vSwitch
exist within the Datacenter
requires Entreprise Plus licensing
allows the VMs to keep the same network conf as they move across hosts
Failover
add 2 NICs to vSwitch
Best practices
at least 2 pNICs & 2 pSwitches
diff networks for vMotion & iSCSI
diff networks for ESXi management
reject promiscious mode / mac address changing
