There are some real advantages to the VSWITCH over a dedicated OSAs: 1. Less real memory consumption. With a VSWITCH there are no locked guest pages. 2. Enforced VLAN controls. A guest can only access the VLANs that you choose. 3. Link Aggregation, providing up to 80 Gb/s throughput AND transparent balancing and failover.
