utilization can improve because of fewer disk waits on page-in and other I/O operations, making more
effective use of capital investments and more conservative use of energy.

For environments that need significant amounts of main memory but which do not need a full 384 GB,
smaller-sized DIMMs can be used in place of 8-GB DIMMs, with resulting cost savings: two 4-GB DIMMS
are typically less expensive than one 8-GB DIMM.

3.2.13 Cisco UCS C-Series Rack-Mount Servers
The Cisco UCS C-Series Rack-Mount Servers (Figure 17) extend the Cisco Unified Computing System
innovations to a rack-mount form factor, including a standards-based unified network fabric, Cisco VN-Link
virtualization support, and Cisco Extended Memory Technology. Designed to operate both in standalone
environments and as part of the Cisco Unified Computing System, these servers enable organizations to deploy
systems incrementally—using as many or as few servers as needed—on a schedule that best meets the
organization‘s timing and budget. Cisco UCS C-Series servers offer investment protection through the capability
to deploy them either as standalone servers in heterogeneous data centers or as part of the Cisco Unified
Computing System.
Although this study was carried out on the Cisco UCS B-Series Blade Servers, the C-Series Rack-Mount Servers
extend the same benefits to customers. Future desktop virtualization studies are planned on this server platform.
