Q. What operating system runs on the Cisco UCS server?
A. Cisco Prime Network Registrar Jumpstart ships preinstalled with and supports the CentOS Linux operating
system version 5.4.
Q. What are the performance expectations?
A. Performance is dependent on a variety of factors. Initial performance testing has shown the following
performance characteristics. Note that these numbers were demonstrated on a system for which few of the
more advanced features of Cisco Prime Network Registrar were configured (for example, no DHCP lease
history, no DHCP failover). In an actual deployment, performance results will vary from those shown below.
Each of the following tests was run individually - they were not run simultaneously.
●
DHCPv4:
◦
New leases: 4293/second
◦
Granting leases to returning clients: 19,798/second
●
DHCPv6:
◦
New leases: 1499/second
◦
Prefix delegation: 3491/second
◦
Granting leases and prefixes to returning clients: 16,254/second
●
DNS Query:
◦
New resource records: 43,640 queries/second
◦
Returning resource records: 70,588 queries/second
Q. Cisco Prime Network Registrar provides DHCP and DNS functionality for Cisco Broadband Access Center.
Is Cisco Broadband Access Center preinstalled on Cisco Prime Network Registrar Jumpstart?
A. No, Cisco Broadband Access Center is not preinstalled on Cisco Prime Network Registrar Jumpstart; however
it does provide full support for Linux and Cisco UCS. Red Hat Enterprise Linux 5 (RHEL 5) and Cisco UCS
support is now extended to all components of the Cisco Broadband Access Center product including the
regional distribution unit (RDU) and the Kerberos Key Distribution Center (KDC).
Q. What is the value of introducing a virtualization layer with VMware ESXi 4.1 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 4.1 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.
