Q. What is the value of introducing a virtualization layer with VMware ESXi between the operating system and the

hardware if the operator has no plans to run additional virtual machines?

A. There is considerable value in running the Cisco Prime Network Registrar virtual machine on top of VMware

ESXi instead of running the operating system directly on the hardware. The value in this case is not realized

so much during day-to-day operations as it is when conditions change or performance weakens. Operators

routinely find that the load that they have placed on a particular server has grown beyond what that server can

handle as network traffic levels increase and requirements change. At some point, an operator may wish to

move Cisco Prime Network Registrar to a larger hardware base. While this task is straightforward in the

traditional model where the operating system runs on bare hardware, it is time consuming at best, incurs some

risk, and may be hard to fit into a maintenance window. However, in a virtualized environment, such as that

provided with the Cisco Prime Network Registrar Jumpstart appliance, the operator can simply shut down the

virtual machine, use VMware tools to copy the virtual machine to another VMware platform, and then turn it on.

This can reduce a complicated and time-consuming task to one that takes only a few minutes.

Q. Can additional virtual machines run on the Cisco Prime Network Registrar Jumpstart appliance? It comes with

VMware ESXi installed.

A. Yes, additional virtual machines can run on the Cisco Prime Network Registrar Jumpstart appliance, assuming

sufficient resources (CPU, memory, disk space, disk bandwidth) are available to support them. Running a

Cisco Network Registrar regional cluster virtual appliance on the hardware (along with the preinstalled Cisco

Prime Network Registrar virtual machine) is one example. Recognize that both the DHCP and DNS servers

included in the Cisco Prime Network Registrar Jumpstart appliance are usually constrained in their

performance by the bandwidth of the disk. You can see this in the performance numbers above, where the

new clients for DHCP require a disk write but granting leases to returning clients does not require any disk

access. Thus, it is recommended that operators ensure there is sufficient disk bandwidth available for all of the

virtual machines they might want to run.

Q. What support is available with Cisco Prime Network Registrar Jumpstart?

A. SMARTnet

support applies to the hardware. Software Application Support (SAS) is available for the Cisco

Prime Network Registrar application.

Q. What type of warranty does the appliance carry?

A. The product ships with a standard 90-day hardware warranty.
