Diagram 1 is an example of a resilient datacenter center designed using
PowerConnect 6024 switches. This solution provides high availability
wire-speed Gigabit routing capabilities to access a large number of servers.
Servers can be connected to the switches using either copper or fiber
cabling. Each switch is capable of supporting up to 21 servers while
providing resilient Gigabit Ethernet uplinks to the network core.
Additionally, the two PowerConnect 6024 switches are connected to each
other to provide higher availability. In the event of an uplink from either
switch losing communication with the core, traffic can still be routed via
the failover links. With the Virtual Redundant Routing Protocol (VRRP),
the routing tables are replicated between the two switches. To ensure high
availability, the PowerConnect 6024’s integrated redundant hot-swappable
power supplies and cooling fans maximize the uptime of the network.
Standards based networking protocols help keep deployment challenges to
a minimum.
Application benefits include:
- Highly-available network connectivity
- High-performance server connectivity
- Cost-effective server connectivity

Diagram 2 is an example of a traffic aggregation solution designed using
PowerConnect 3348, 5224 and 6024F switches. This solution can provide
high availability and fail-over protection for a large number of desktop
clients.
In this example, the PowerConnect 6024F switches connect different
subnets or VLANs to the network core using multiple fiber SFP ports as a
single IEEE 802.3ad aggregated link. The aggregation switch provides
Layer 3 capabilities which enable it to route traffic without having to
