Hi Amr

•Enable higher scale in logical ports (also called P,V ports)
•Important for customers with:
•ESX DVS or Nexus 1kV
•Multi-tenant – Service Provider/Enterprise
•High # of Servers with high # of VLAN – GET/Enterprise/Commercial/SLED
 
•Optimizes (P,V) to increase supported limit
•Increase Scale from 32K to up to 64K* on the Fabric Interconnect 6248/6296
 
•Example
•5 clusters of 32 ESX hosts (160 hosts total)
•Each ESX host has 4 static vNICs (2 per fabric)
•Each cluster has 150 VLANs that do not overlap across clusters
•Each vNIC carries 150 VLANs
•Number of VIFs: 160 x 4 = 640
•8 Ethernet border ports carrying all the VLANs
•Number of VLANS: 5 x 150 = 750
•PV count = 160 x 2 x 150 + 8 * 750 = 54,000
