Services plane: Enabling the Branch-in-a-Box
All Cisco ISR 4000 routers contain processing cores built-in as standard to allow full-featured services to
run on-board. This includes the full-featured Cisco WAAS engine that provides application acceleration
and highly responsive virtual desktop experience. The technology is known as Cisco Service Containers
and it uses a standard hypervisor to allow x64 based applications to run.
The 4000 series routers can be fitted with Solid State Drives (SSD) and server cards for local storage and
computing capability. The Cisco UCS-E server cards are available with 8-core Intel Xeon processors with
up to 48GB of high speed DDR3 memory and three drives built in offering RAID 0, 1 and 5. This immense
amount of compute power can eliminate the need for any dedicated servers at branch sites. UCS-E cards
can be configured and managed using VMware vCenter and pooled with Data Center compute resources.
