Building a server could take weeks while the hardware was procured, provisioned, configured, application
templates developed, and applications installed. Adding servers and cabling to help ensure capacity also resulted
in increased capital costs and operating expenses such as electrical costs. The facility in which Hannover’s data
center is housed began charging the data enter separately from the company’s office space, metering electricity
use and adding a premium to the bill. With aging servers and increasing workloads, it was time to evaluate a
new solution.

“For us, an important factor in choosing the Cisco Unified Computing System platform was the ability to have an
end-to-end, single-vendor solution,” says Patel. “In addition, Cisco’s support for our core infrastructure over the
years has been the best we have ever received. It was very easy to follow Cisco into the server space, where we
could rely on the same technical support for our servers as well.”

Nexus 5010 Series switches. Physically, the Nexus 7000 and 5000 Series switches are
connected with 10-GB fiber links.
The switches also support a 100-MB connection to Orlando headquarters. With existing Cisco Wide Area
Application Services appliances and Cisco Wide Area Application Services software, Patel’s team can provide
high-performance access to applications, storage, and video content, across the wide area network.

As the team transitioned from its existing servers to Cisco Unified Computing System™ Blade Chassis, the servers
were connected to the Nexus switches with 40-GB fiber connections. Fibre Channel uplinks connect the Cisco
Unified Computing System pods to Hannover’s storage area network (SAN). Cisco UCS 6120XP 20-Port Fabric
Interconnects are deployed in a redundant pair, providing uniform access to the network and storage.

Hannover deployed Cisco Unified Computing System B-250 M2 blade servers, using the Intel Xeon processor
5600 series. Intel Hyper-Threading Technology delivers superior throughput and responsiveness for multithreaded
applications, such as Hannover’s modeling application. Intelligent performance of the Intel Xeon processor 5600
series enables Patel’s team to quickly adapt to support changing loads.

Hannover moved three full racks, or 77 physical servers, to 77 virtual machines (VMs) running in one Cisco UCS
pod on one-third of a rack. All of these VMs are running on a single Cisco UCS B250 M2 blade.

“Cisco UCS allows us to have flexible workloads. When we need more
computing power, we can quickly deploy more VMs. When workloads
drop, we can power down the servers and reduce power and cooling
costs. We are looking forward to much lower costs.”
