14 CHAPTER 1: INTRODUCTION Onboard 3XP Processor The 3CR990 NIC represents a new generation of secure, intelligent client NICs with an onboard RISC processor (3XP processor). The 3XP processor is designed to optimize system and network performance. The NIC off-loads key networking and security tasks from the host PC CPU (central processing unit) to the 3XP processor, even when running bandwidth-intensive applications such as voice, video, imaging, and Internet and intranet applications.

18 CHAPTER 1: INTRODUCTION Load Balancing Load balancing maximizes bandwidth at the server through the use of multiple parallel resilient server links (RSLs) that share the network load. An RSL consists of two or more NICs that form a virtual NIC. Each virtual NIC has multiple physical NICs bound to it, forming a group. Each NIC in a group uses the same protocols and frame types. One NIC is designated the primary NIC and the others secondary NICs. Figure 2 Types of Load Balancing Arrange

3CR990 NIC Features 19 failed NIC. The failover behavior of secondary NICs depends on how you set load balancing: In a transmit load balancing arrangement, the primary NIC is the only one that receives packets. If the primary NIC fails, a secondary NIC assumes the configuration profile, network traffic, and active status of the failed primary NIC. In a bidirectional load balancing arrangement, all NICs receive packets. If any NIC fails, receive load balancing is disabled, and the other

With VLANs, you can define a network according to: Organizational groups—For example, you can have one VLAN for the Marketing department and one for the Finance department. Application groups—For example, you can have one VLAN for e-mail users and one for multimedia users. Implementing VLANs on a network has these advant
