Forward-looking hardware
A significant proportion of the network at BMW AG has been based on Cisco components for
several years. In terms of cost-effectiveness, power consumption and enabling a future-capable
network infrastructure in the Enterprise Data Center, the Cisco Nexus platform proved to be the
ideal replacement for the previous Catalyst components. The Cisco Nexus architecture with the
Cisco NX-OS operating system is scalable to over 15 terabits per second and in future will
combine Ethernet with the transport of storage data on a single platform. With this "unified fabric",
each server can then access all resources — paving the way for a complete virtualisation of the
data centre.

each server can then access all resources — paving the way for a complete virtualisation of the
data centre.
The new network design involves the use of external line cards in dedicated network racks. For
each of the five required infrastructures, including double high availability, integrated Lights-
Out (iLO), administration and backup, one Nexus 2248T is used as a "fabric extender" in each of
the dedicated network racks. These fabric extenders are connected via Multimode using two
or four 10GB links to the Nexus 5548 in the relevant star points of the total 14 smoke sections.
The Nexus 5548 are connected to the Nexus 7010 on the distribution level in a V formation,
each with four 10GB links. The network headquarters, in turn, are connected to the relevant
smoke sections via single-mode fibreglass cables. Both the access level and the distribution
level are configured in the vPC design (Virtual Port Channelling) in order to guarantee high
availability. Due to vPC, two physical switches appear as the same end point to a connected
device. The advantages of this include more effective use of the available bandwidth. The
installation of the new network took almost a full year from the end of 2010 to the end of 2011.
The complete reconfiguration using parallel provision of the new infrastructure will continue for
at least another year.

Benefits resulting from the operating system
Cisco provided support to BMW in the architecture approach, in compiling the desired
configuration and in the selection of the final optimum design. Additional quality assurance was
secured through close cooperation in the configuration of the components. The selected solution
components from the Nexus 7000, Nexus 5000 and Nexus 2000 series were tested extensively in
a customer proof of concept in October 2010. The Cisco solution offers the advantage of
installing access ports in different places within a smoke section using non-modular components
without simultaneously increasing the number of active components. As a result, the hardware
management is significantly more efficient. The modular concept of Cisco NX-OS, the operating
system for the Nexus 7000 series, offers high redundancy, with the ability to isolate error sources.
Further strengths of the solution include more efficient use of resources, process modularity and
the uninterrupted software update ISSU (In-Service Software Upgrade). ISSU increases the
availability of the network infrastructure in the Enterprise Data Centre and reduces the downtime
required for software updates. In comparison to a similarly configured constellation based on
Catalyst, the new IT infrastructure based on Nexus has lower power consumption and is therefore
more energy-efficient. The capital and maintenance costs are also considerably lower. On-going
support for the solution is provided by the Cisco Technical Assistance Centre (TAC).
