When outlining the potential financial savings from having virtualized network services
modules, which statement would be a supportable statement to make?
A.
Because the services are virtual, virtual network services modules will take up no rack
space and will consume no power.
B.
The savings will depend upon the requirements for each data center but can be as much
as 80 percent on power and 30 units of rack space.
C.
Virtual services modules can support up to a maximum of four virtual contexts, so they
can save up to 75 percent of both power and rack space.
D.
Every time a new virtual context is created, the services modules draw 50 percent more
power than a single-context operation, so the maximum number of virtual contexts is limited
to four per module. With the maximum of four virtual contexts, the total power consumed is
250 percent of a single context operation, which is 150 percent less power than four
physical service appliances would draw.
