In addition to the Layer 2 switching capabilities, this switch supports the expanded capabilities of Layer 3 routing. The BladeCenter S chassis supports up to three switch modules for typical applications. The modules can be hot-plugged into the BladeCenter chassis without disrupting normal operations. The switch connects to the server blades via the 14 internal GbE interfaces server ports over the BladeCenter mid-plane.

In addition to the Layer 2 switching capabilities, this switch supports the expanded capabilities of Layer 3 routing. The BladeCenter S chassis supports up to three switch modules for typical applications. The modules can be hot-plugged into the BladeCenter chassis without disrupting normal operations. The switch connects to the server blades via the 14 internal GbE interfaces server ports over the BladeCenter mid-plane.

It supplies nine external Ethernet interfaces for outside communication. Full Layer 2 switching and Layer 3 routing enable flexible in-chassis, traffic management and sophisticated security.

In particular, the switch module supports up to 16, MAC addresses, address resolution protocol ARP entries, and up to dynamic route entries to ensure a high level of support for a number of users. The IEEE Adding full Layer 3 routing to the integrated switch module delivers more power, flexibility, and security capabilities to the BladeCenter system.

You can manage network traffic more efficiently with the integrated switch module. You can also contain Broadcast traffic in the blade server by placing the 14 server blades on different subnets.

This enables communication between each without using the bandwidth of the external ports to send traffic to and from an external L3 device. Security features help deliver added protection for switch configuration data. Packet filtering helps secure and segment sensitive traffic or network access. Multilevel access and defined access policies help secure the switch against unauthorized management access.

Layer 3 filtering IP, application type, and so on at line rate in the chassis enhances security and simplifies provisioning. The risk of traffic finding a route to a denied destination is reduced if Layer 3 routing is contained in the switch module in the chassis.

Without Layer 3 filtering, several external switches might need configuration to filter traffic to limit access between one server blade and another if the traffic flows through upstream devices. In addition, the switch hardware is capable of supporting a wide range of IPv6 protocols in the future with an optional firmware upgrade.

Applications get the bandwidth they need, when they need it, with little or no delay or jitter. Even with all the value that an integrated switch module can offer, a BladeCenter server can have its performance limited if the switch module cannot enable adequate ingress and egress bandwidth. They support full Layer 2 through Layer 3 wire-speed packet forwarding for all connections.

In addition, the flexibility of both copper and fiber ports allow for optimized use in hybrid installations or where one switching infrastructure is more economical. At Layer 2, Link Aggregation Control With this feature, all switches in the VRRP group concurrently process traffic, enabling maximum switch performance. It helps providing failover support in the unlikely event of a failure.
