IBM® j-type data center solutions running Junos software (from Juniper Networks) provide operational agility and efficiency, dramatically simplifying the network and delivering savings. With this solution, a network design has fewer devices, interconnections, and network tiers. Beyond the cost advantages, the design offers the following key benefits: Reduces latency Simplifies device management Delivers significant power, cooling, and space savings Eliminates multiple system failure points Performs pervasive security The high-performance data center is built around IBM j-type e-series Ethernet switches, m-series routers, and s-series firewalls. This new family of powerful products helps to shape the next generation of dynamic infrastructure. IBM j-type e-series Ethernet switches meet escalating demands while controlling costs. IBM j-type m-series Ethernet routers are high-performance routers with powerful switching and security capabilities. This IBM Redbooks® publication targets IT professionals who sell, design, or administer IBM j-type networking solutions. It provides information about IBM j-type Ethernet switches and routers and includes the following topics: Introduction to Ethernet fundamentals and IBM j-type Ethernet switches and routers Initial hardware planning and configuration Other configuration topics including Virtual Chassis configuration, Layer 1, Layer 2, and Layer 3 configurations, and security features Network management features of Junos software and maintenance of the IBM j-type series hardware
