GSS 4490 Global Site Selector
Introduction
The Cisco® GSS 4490 Global Site Selector provides the foundation for multisite disaster recovery plans by globally load balancing distributed data centers. The Cisco GSS 4490 is the second addition to the Cisco Global Site Selector Series. This new hardware platform, along with the recently released Cisco Global Site Selector Software Release 1.1 improves end-user's management experience and increases resource capacity for advanced applications and features.
The Cisco GSS 4490 acts as the cornerstone of multisite disaster recovery plans in deployments of Cisco's market-leading content switches. Customers deploying new Cisco content switches such as the Cisco CSS 11500 Content Services Switch and Content Switching Module (CSM) for the Cisco Catalyst® 6500 Series switches or customers who have already deployed legacy switches such as the Cisco CSS 11000 and Cisco Local Directors can benefit from the new levels of traffic management and centralized command and control provided by the Cisco GSS 4490.
The Cisco GSS 4490 delivers the following capabilities:
- Provides a scalable, dedicated hardware platform for industry-leading Cisco content switches to help ensure that Web-based applications are always available, by detecting site outages or site congestion and rerouting content requests
- Improves the global data-center selection process, by offering user-selectable global load-balancing algorithms
- Offloads Domain Name System (DNS) servers by taking over the domain resolution process and transmits these requests at thousands of requests per second
- Scales to support hundreds of data centers and server load balancers
- Complements existing DNS infrastructure by providing centralized domain management
- Integrates tightly with Cisco server load balancers without compromising the ability to work in a heterogeneous environment of DNS-capable networking products
Available Models
The Cisco GSS 4490 is available in a single model and supports only AC power. There is an option to select the proper power cable. The Cisco GSS 4490 comes in a 1-rack unit (RU) form factor. Table 1 gives ordering information for the Cisco GSS 4490.
