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 IP Express 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 IP Express 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 IP Express 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 IP Express Jumpstart appliance? It comes with
VMware ESXi installed.
A. Yes, additional virtual machines can run on the appliance, assuming sufficient resources (CPU, memory, disk
space, disk bandwidth) are available to support them. Running a Cisco Prime IP Express regional cluster
virtual appliance on the hardware (along with the preinstalled Cisco Prime IP Express virtual machine) is one
example. Recognize that both the DHCP and DNS servers included in the Cisco Prime IP Express 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 IP Express Jumpstart?
A. SMARTnet
®
support applies to the hardware. Software Application Support (SAS) is available for the Cisco
Prime IP Express application.
Q. What type of warranty does the appliance carry?
A. The product ships with a standard 90-day hardware warranty.
Q. Where and when can I obtain more information?
