Performance/Capacity
Hardware-Based High Availability Features
The S-Series includes many standard high availability features. These hardware-based high availability features allow the S-Series to be deployed in
mission critical environments that require 24/7 availability.
The S-Series supports the following hardware-based high availability features:
• Passive chassis backplane in the S1, S3, S4, S6, and S8 chassis
• Meshed backplane architecture in the S3 chassis
• Hot swappable fan trays with multiple cooling fans
• Separate system and PoE power supplies
• Hot swappable power supplies
• Multiple AC input connections for power circuit redundancy
• Load sharing/redundant I/O fabrics in the S4, S6, and S8 chassis
• N+1 fabric redundancy in the S8 and S6 chassis
• Hot swappable I/O fabrics and I/O modules
• Multiple host CPU for N+X redundancy
• Virtual Switch Bonding (bonds two physical switches to create a single logical switch)
Optimized, High-Availability and Self Healing Services
Aside from the standard high-availability features of typical wiring closet and data center switches, the Enterasys S-Series includes many advanced self
healing features such as dynamic service fail-over, automatic module self-configuration, and multi-image support.
Dynamic service fail-over enables each I/O module service (e.g., management, switching/VLANs, routing, etc.) to be automatically switched to another I/O
module in an event of module or process failure. This “self healing” capability happens in milliseconds because each service is replicated in real-time on
every I/O fabric and I/O module.
Automatic module self-configuration is another innovative feature that allows I/O modules to receive their configuration from other I/O modules
automatically. This is ideal for replacing failed modules without manually reconfiguring the replacement module.
The Enterasys S-Series allows users to download and store multiple firmware image files; this feature is useful
for reverting back to a previous version in the event that a firmware upgrade fails. This multi-image support
provides significant operational efficiencies especially with regard to the application of firmware patches.
Distributed, Flow-Based Architecture
In order to ensure granular visibility and manage of traffic without sacrificing performance, the Enterasys
S-Series deploys a distributed, flow-based architecture. This architecture ensures that when a specific
communications flow is being established between two end points, the first packets in that communication
are processed through the multilayer classification engines in the switch I/O modules and I/O fabric modules.
In this process, the role is identified, the applicable policies are determined, the packets are inspected,
and the action is determined. After the flow is identified, all subsequent packets associated with that flow
are automatically handled in the Enterasys ASICs without any further processing. In this way the Enterasys
S-Series is able to apply a very granular level of control to each flow at full line rate.
