Q. What operating system runs on the Cisco UCS server?
A. Cisco 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 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 Network Registrar provides DHCP and DNS functionality for Cisco Broadband Access Center (BAC). Is
BAC preinstalled on Cisco Network Registrar Jumpstart?
A. No, BAC is not preinstalled on Cisco Network Registrar Jumpstart; however BAC 4.2 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 BAC 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 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 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 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.
