ULTRA-HIGH AVAILABILITY THROUGHOUT
THE FABRIC
The core-to-edge SAN model features
redundancy within the director as well as
a high-availability network approach for
the entire fabric.The ultra-high-availability
features of Brocade Fabric OS
®
help provide
a SAN infrastructure capable of delivering
continuous overall system availability with
features that include:
• Non-disruptive software upgrades and
hot code activation
• Dual-redundant control processors with
stateful failover
• Redundant, hot-swappable components and
redundant power and cooling subsystems
• Continuous monitoring of environmental
components
• Power-On Self-Test (POST), online/offline
diagnostics, and per-port statistics
• Error detection and fault isolation facilities
• Call-home capabilities to provide remote
notification of system events
A NEW LEVEL OF SAN SECURITY
To help protect valuable information, the
SilkWorm 24000 supports Brocade Secure
Fabric OS
®
, the most comprehensive fabric-
based security platform available. Based on
the latest networking security technology,
Secure Fabric OS addresses a wide variety
of vulnerabilities within the SAN fabric and
helps prevent downtime due to human error.
INDUSTRY-LEADING PERFORMANCE
With a fully non-blocked architecture
supporting 128 ports concurrently active
at 2 Gbit/sec full-duplex, the SilkWorm
24000 supports the most demanding SAN
applications at the core of large SANs. It
employs a multistage shared memory
architecture that reduces latency in port-to-
port transfers to 2.1 microseconds or less.
To provide even higher performance,
Brocade ISL Trunking with 2 Gbit/sec
blades combines up to four ISLs between
a pair of switches into a single, logical
high-speed trunk running at up to
8 Gbit/sec.With 4 Gbit/sec blades, an
ISL trunk can include up to eight ports for
as much as 32 Gbit/sec of data throughput.
