Network and IT Profile

SAVVIS operates one of the largest, global, wholly owned infrastructures, operating in 110 cities from 45 countries. It has over 1.4 million square feet of data center space under management from 24 managed data centers distributed around the world, and plans to add several new data centers by the end of 2007 and into

2008. The infrastructure interconnects over 32,000 network elements/circuits, hosts/servers, and storage devices. Connectivity is provided over a Tier 1 OC-192 MPLS backbone operated by SAVVIS with industry-leading 99.99 percent availability Service Level Agreements (SLA), which reduces the need for expensive backup circuits and ensures optimal performance. The features offered by this infrastructure are leveraged to deliver and optimize a wide variety of services offered by SAVVIS:

• Public Internet

• Financial platform services

• Managed hosting

• Utility compute and storage services

• Security services

• Professional services

SAVVIS' ATN integrates the networking and hosting infrastructures into a single, high-bandwidth, high-availability, QoS-enabled platform. Both unicast-and multicast-based services are supported. This service-oriented network enables SAVVIS to deliver the enterprise applications needed by businesses and government agencies.

The conceptual structure of the ATN is shown in Figure 5-6.

The OSs currently deployed in SAVVIS' infrastructure and those it plans to use going forward are listed in Table 5-15.

SAVVIS uses a sophisticated combination of network management, billing, and provisioning tools, most of which are commercial off-the-shelf (COTS) products that are adapted to its needs while augmented with others that are built in house, to ensure seamless delivery of its IT services to its customers.
