HighAvailability

A high-performance network connection, whether it connects PCs and IP telephones at the

access layer or interconnects servers in a cluster, is useful only if it is also highly available. To

achieve voice-class network availability, NETGEAR 8800 Series chassis switches combine highly

resilient software and redundant hardware with high-availability network protocols.

The hardware design of the NETGEAR 8800 Series switches includes redundant Supervisory

modules, power supplies, and other components. Redundant Supervisory modules provide

an automatic failover mechanism that allows the second Supervisory module to automatically

assume management responsibility for the entire chassis if the rst Supervisory module fails.

The advanced chassis design features a passive backplane complemented by high availability

elements, such as isolated control and data planes and redundant controller boards for

power distribution.

The chassis accommodates up to six load-sharing power supplies, providing a variety of

redundant power congurations to support high-density implementations with and without PoE.

Three power supplies in a 2 + 1 redundancy conguration can power a fully loaded chassis

with gigabit or 10 Gigabit Ethernet ports. Additional power supplies support PoE deployments.

A tray of nine fans (NETGEAR XCM8810 switch) or six fans (NETGEAR XCM8806 switch) provides

redundant cooling for the chassis. The fan tray itself is hot swappable, allowing the NETGEAR

8800 Series switches to continue operation while the fan tray is replaced.

The NETGEAR OS provides true preemptive multitasking and protected memory. Each of the

many protocols, such as OSPF or Spanning Tree, runs as a separate process, protected from

other processes. In addition, the NETGEAR OS software monitors independent operating

system processes in real time. If any process becomes unresponsive, or stops running, it is

automatically restarted. In addition to increasing system integrity, this operational design

inherently protects against Denial of Service (DoS) attacks. The modular design of the

NETGEAR OS software allows new functionality to be added to the switch easily, extending

switch functionality.

NETGEAR 8800 Series switches run a collection of high-availability protocols that allow the IP

network to provide the levels of resiliency and uptime that have traditionally been associated

with voice networks. The Spanning Tree (802.1D), Per VLAN Spanning Tree (PVST+), Rapid

Spanning Tree (802.1w), and Multiple Instances of Spanning Tree (802.1s) protocols support

Layer 2 resiliency. Cross-module link aggregation (802.3ad) enables trunking of up to eight

links on a single logical connection, for up to 80 Gbps of redundant bandwidth per logical

connection.

Software enhanced availability allows users to remain connected to the network even if part

of the network infrastructure is down. NETGEAR 8800 Series switches continually check for

problems in the uplink connections and use advanced Layer 3 protocols such as OSPF and

VRRP to dynamically route around the problem. Equal Cost Multipath enables uplinks to be

load balanced for performance and cost savings while also supporting redundant failover.

If an uplink fails, trafc is automatically routed to the remaining uplinks and connectivity

is maintained.

High-PerformanceConnectivity

Networking trends show an increasing number of devices at the edge of the network, including

IP telephones, wireless access points (APs), and other devices. These networking trends drive

the requirement for Gigabit Ethernet to the desktop and the use of 10-Gigabit Ethernet as

an interconnect technology. NETGEAR 8800 Series switches deliver high-performance, cost-

effective connectivity to address these trends.

The NETGEAR 8800 Series switches provide local switching on every I/O module, as well as

48 Gbps per slot bidirectional bandwidth, for high-density, cost-effective, line-rate connectivity.

Three different types of hot-swappable I/O modules are available. Gigabit modules feature

either 48 xed copper ports or 24 pluggable SFP optical modules; 10-Gigabit modules feature

8 pluggable XFP optical modules. The NETGEAR 8800 Series switches support up to 400

Gigabit ports or up to 64 10 Gigabit ports in a single chassis. Redundant Supervisory modules
