A VSD may contain either an Intel Xeon 2.1GHz or 2.3GHz 8-core
microprocessor. The VSDs must be installed in pairs and the VSDs control the
front-end directors, back-end directors, PCI-Express interface, local memory,
and communication to the SVP. The VSDs are independent of the front-end
directors and back-end directors, and can be shared across them.

The CPA uses the built in switch to connect the VSDs to the front-end
directors, back-end directors, and the cache backup memory. It distributes
data (data routing function) and sends hot-line signals to the VSD. The
shared memory is located on the first CPA cache board in each cluster in the
primary controller
