Memory and I/O always the most important pieces in virtualization environment which will define the consolidation ratio in server virtualization. This will direct impact the TCO and ROI for the data center project. Cisco had launched their UCS server for quite some times which able to scale up the server memory up to 384 GB per 2 CPU server. Cisco UCS support up to 48 DIMMs slot in a single blade or rack mount server follow with the 250 M1 series product range.

This picture show how the memory architecture been define in the Cisco memory architecture.

It will definitely be helpful and encourage more users to be adopted on nexus 1000V implementation in the Virtual Infrastructure when the VMware vSphere 4 are deploying on Cisco UCS platform. If you are running the VMware vSphere 4 with others server vendor, the Nexus 1000V will be an extra features with additional cost.
