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.



In this picture you can see that it present logically 32 GB which combine 4 x 8GB physical Ram with the Cisco UCS Extended memory technology.
With the expensive 8 GB memory module today, to have a server running with high memory capacity will not able to justify as part of the project business case. But with this technology in place, you will able to scale up to 192 GB per 2 CPU server by using 4 GB memory module. This will significant improve the consolidation ratio of the virtualization project and provide a better ROI for sure.
