Dell PowerConnect M6220 1GB Ethernet 24 Port Switch 155HJ for M1000e

Overview
The Dell PowerConnect M6220 is a key component of the FlexIO architecture of the M1000e Modular Server Enclosure. FlexIO delivers a level of IO flexibility, bandwidth, features, and investment protection unrivaled in the blade server market. The M6220 is a break-through modular design that packages a high-performance 24-port stackable Ethernet switch with modular bays that can be populated with 10GbE or stacking modules to provide customers with the flexibility to create exactly the switch they need for their environment. One of the most powerful features of the M6220 is the ability to stack multiple switches together, thereby creating a single logical switch that can be managed and configured as one. This stacking capability is especially powerful when combined with the ability to uplink to the Ethernet core via high bandwidth 10GbE connections. This White Paper describes the basics of stacking, a description of the hardware and architecture, configuration hints, and some sample use cases.

Value And Flexibility
The PowerConnect M6220 offers additional value because the modular design allows you to upgrade to advanced stacking or 10GE when you need it. It helps provide further flexibility and value with optional modules that allow for either 10 Gigabit optical or CX-4 copper interfaces — or both, based on your needs.

High Density
The PowerConnect M6220 is designed to give users the flexibility to maximize server and workstation connectivity. The M6220, along with Dell blade servers, can help users address space constraints, reduce cabling requirements, and can help lower overall TCO. It offers integrated Gigabit connectivity and 10 Gigabit Ethernet (10GE) options for the PowerEdge M1000e Modular Server Enclosure. Up to 240 servers and/or clients can be connected in a stack of 12 M6220 switches to help provide maximum density, flexibility, and manageability.

High-Performance Stacking
The PowerConnect M6220 supports high-performance, 48 Gbps stacking bandwidth for up to 12 systems, which allows increased throughput to be added as needed without affecting network performance. With each switch supporting up to 128 Gbps in switch bandwidth, the customer can have over 1.5 terabytes of bandwidth in a single stack of 12 switches.

10 Gigabit Ethernet
The PowerConnect M6220 switch supports up to four 10GE uplinks which allow users to add bandwidth as they need it, and consolidate uplinks across the stack for further cable reduction. The two 10 Gb module slots support two 10 Gb ports each, with a wide variety of port variants.

Advanced Layer3 Capabilities
The PowerConnect M6220 supports advanced Layer 3 routing and multicast protocols to help reduce congestion and manage traffic in the network. It also supports frequently used LAN routing protocols such as RIPv1/v2, OSPFv2/v3, VRRP, IGMPv2, DVMRP, PIM, and LLDP-MED.

Advanced Security
Up to 1,024 L2-L4 Access Control Lists (ACLs) can be supported on the switch, allowing the user to perform deep packet inspection. 802.1x port authentication offers both single and multiple host access. Further security is provided through Denial of Service (DoS) Attack Prevention, whereby the switch can help protect against common network and CPU attacks.

IPv6 Support
Both the hardware and software for the PowerConnect M6220 support IPv6. In development for over 20 years, IPv6 has been designed to resolve IP address limitations of the previous version of the Internet Protocol, enabling an increased number of unique IP addresses for broader scalability worldwide now and in the future.
