Extreme Networks Data Sheet
Voice-Class Availability
Redundant Hardware Design
Redundant Management Modules
BlackDiamond 10808 is configured so
that if one Management Switch Module
(MSM) fails, the second MSM will
automatically take over management
responsibility for the entire switch. This
feature is critical for networks running
voice and other mission-critical
applications.
Advanced Chassis Design
for Availability
BlackDiamond 10808 includes a passive
backplane complemented by high-
availability design elements such as
isolated control and data planes, redundant
controller boards for power distribution
and fan control, and environmental
monitoring to identify anomalies before
they affect network availability.
Redundant Load Sharing
Power Supplies
BlackDiamond 10808 supports a set of
redundant power configurations that can
load share up to six internal power
supplies simultaneously. Four power
supplies in a 3 + 1 redundancy configura-
tion can power a fully loaded chassis with
gigabit or 10 Gigabit Ethernet ports. Six
power supplies in a 3 + 3 configuration
can provide input power redundancy.
Modular Operating System for
Non-stop Operation
True Preemptive Multitasking
and Protected Memory
ExtremeXOS allows each of the many
tasks—such as Open Shortest Path First
(OSPF) and Spanning Tree—to run as
separate operating system tasks that
are protected from each other as shown
in Figure 2.
Process Monitoring and Restart
ExtremeXOS dramatically increases
network availability by monitoring in real
time the independent operating system
processes. If any of them become
unresponsive, or stop running, they are
automatically restarted.
Loadable Software Modules
The modular design of ExtremeXOS allows
the extension of switch functionality. New
functionality can easily be added to the
switch.
High Availability Network
Protocols
Ethernet Automatic Protection
Switching
EAPS allows the IP network to provide the
level of resiliency and uptime that users
expect from their traditional voice networks.
EAPS is superior to the Spanning Tree or
Rapid Spanning Tree Protocols, offering
sub-second (less than 50 milliseconds)
recovery and delivers consistent failover
regardless of number of VLANs, number of
network nodes or network topology. In most
situations, VoIP calls don’t drop and digital
video feeds don’t freeze or pixelize because
EAPS enables the network to recover
almost transparently from link failure.
Spanning Tree/Rapid Spanning
Tree Protocols
BlackDiamond 10808 supports Spanning Tree
(802.1D), Per VLAN Spanning Tree (PVST+),
Rapid Spanning Tree (802.1w) and Multiple
Instances of Spanning Tree (802.1s) protocols
for Layer 2 resiliency.
Software Enhanced Availability
Software enhanced availability allows
users to remain connected to the network
even if part of the network infrastructure
is down. The BlackDiamond 10808 switch
constantly checks for problems in the
network connections using advanced
Layer 3 protocols such as OSPF (with
graceful restart), VRRP and ESRP (ESRP
supported in Layer 2 or Layer 3), and
dynamically routes around the problem.
Equal Cost Multipath
Equal Cost Multipath enables uplinks to
be load balanced for performance and cost
savings while also supporting redundant
failover. If an uplink fails, traffic is
automatically routed to the remaining
uplinks and connectivity is maintained.
Link Aggregation (802.3ad)
Cross-module link aggregation enables
trunking of up to eight links on a single
logical connection, for up to 80 Gbps of
redundant bandwidth per logical connection.
A high-performance network connection, whether used to connect PCs and IP telephones at the access layer or to interconnect
servers in a cluster, is only useful if it is also highly available. BlackDiamond 10808 utilizes the industry-leading ExtremeXOS
modular operating system that raises the availability of the switch. Network level resiliency protocols are added to increase the
availability of the network.
