Chapter 1 Product Overview
Administrative Features
Nonblocking Architecture
The Cisco SFS 7000P and SFS 7000D Server Switches provide nonblocking switch element architecture
with full bisectional bandwidth for the switch chassis.
Administrative Features
This section describes the administrative features of the Cisco SFS 7000P and SFS 7000D Server
Switches and includes these topics:
• Real-Time Clock, page 1-5
• Latency, page 1-5
• Nonvolatile Memory, page 1-5
• Diagnostics, page 1-5
• Diagnostics, page 1-5
Real-Time Clock
A real-time clock maintains correct time regardless of power conditions or connectivity.
Latency
The Cisco SFS 7000P Server Switch has port to port latency of less than 200ns.
The Cisco SFS 7000D Server Switch has port to port latency of less than 140ns
Nonvolatile Memory
The nonvolatile memory supports the following items:
• Three stored system images (not including recovery image)
• One week of log files at normal verbosity and one day of log files at maximum verbosity
Diagnostics
The following tests are used to determine operational status:
• POST is performed on all system components and is required during power-on to determine
operational readiness.
• Tests are available to check the operational status of the redundant component periodically during
normal operation, including the logic required to perform the transition from faulted or primary to
redundant component. The test reports the detection of an abnormal status.
• Some other diagnostics that you can perform are card self-test, chassis self-test, and fan self-test.
See Chapter 6, “Hardware Diagnostic Tests” for more information.
