IBM BladeCenter Layer 2-7 Gigabit Ethernet Switch Module

The IBM BladeCenter Layer 2-7 Gigabit Ethernet Switch Module serves as the switching and routing fabric for the IBM BladeCenter server chassis. It also introduces Layer 4-7 functionality for application-based and server-based load balancing, advanced filtering, content-aware intelligence, embedded security services, and persistence support. The Switch Module supplies four Gigabit Ethernet External copper ports, 14 Gigabit Ethernet internal ports, and two 10/100 Ethernet management ports.

Did you know?
The IBM BladeCenter Layer 2-7 Gigabit Ethernet Switch is the only blade switch in the industry to provide enhancements to the standard Layer 2 switching functions by introducing Layer 3 Routing, Layer 4 through Layer 7 Virtual Server Load Balancing, application availability, and security features consolidated into a standard form factor I/O module. It supports up to 300,000 simultaneous Layer 2 through Layer 7 sessions and full wire-speed packet forwarding for all connections. This switch is ideal for infrastructure applications requiring load balancing such as TCP/UDP, firewalls, VPN, SIP for Voice-over-IP, Microsoft Terminal Server (RDP), and IBM Enterprise Workload Manager.

Benefits
The IBM BladeCenter Layer 2-7 Gigabit Ethernet Switch Module flattens the topology of the data center infrastructure, resulting in fewer devices which translates into lower capital and operating expenses. The Layer 2-7 Gigabit Ethernet Switch Module offers the following benefits:

• Enables consolidation of full Layer 2-7 LAN switching capabilities into IBM BladeCenter
• Supports virtualized network services using VLANs, Virtual IPs, Virtual Server Router and Virtual Router Redundancy Protocol
• Helps avoid unplanned downtime with automatic failover that boosts availability
• Reduces cable clutter (no cables server to switch)
• Provides seamless integration with third-party switches
• Consumes only 40 watts, which is ideal for clients with power limitations or for those who simply want to reduce operating costs and be more environmentally friendly. This is one-fifth the power consumption and half the cost of an external layer 2-7 switch.
• Offers load balancing across multiple chassis in addition to internal and external servers.
• Exceptional Security: Denial-of-Service protection, Syn Attack detection, and more. NAT provides additional security and IP address scalability

Connectors and LEDs

Figure 4 shows the front panel of the Layer 2-7 Gigabit Ethernet Switch Module.

Figure 4. The front panel of the IBM BladeCenter Layer 2-7 Gigabit Ethernet Switch Module The front panel contains the following components:

• Four external 1000BASE-T Ethernet ports for 10/100/1000 Mbps connections to external Ethernet devices.
• LEDs that display the status of the switch module and the network. These LEDs are:
• OK, which indicates that the switch module has passed the power-on self-test (POST) with no critical faults and is operational
• Switch module error, which indicates that the switch module has failed the POST or detected an operational fault.
• One RS-232 console port provides an additional means to install software and configure the switch module. This 8-pin DIN connector allows the connection of an 8-pin DIN  to a DB9 serial cable. The serial cable is supplied with the switch module. The protective cap must be removed while the console port is in use and should be reinstalled when the console cable is disconnected.
