1.4.4. Host Considerations
A host vendor is required to supply at least two samples. In some cases up to two samples will be run through testing
in parallel at a given time. In most cases, the second or third sample shall not be secured within a chassis or platform
case, as this sample may be used specifically for mechanical testing.
Prior to execution of any testing on a host, a “worst port” must be identified. The intent of identifying a worst port is
not to validate each port to the specification, but to simply identify the worst port based on a single relative
measurement across all ports within a host. The Interoperability Tests shall then, at a minimum, be executed on the
worst port identified per the procedure below.
Power-on host and ensure test ports are enabled & functional. Run the following on each individual port.
o Connect device and complete OOB sequence
o Execute and record results for the typical Total Jitter (TJ) measurement using LBP while the host is in
NRZ idle following OOB
The “worse port” is identified as that which has the highest TJ value recorded on the measurement above
Relative to the Interface Power Management tests (see section 2.5), it is expected that the host product manufacturer
supply a facility (software, or hardware automation) which will initiate power management state requests in order to
support host-initiated test execution this is only required if the host product claims support for the host-initiated
power management capability.
1.4.5. Port Multiplier Considerations
A port multiplier vendor is required to supply at least two samples. In some cases up to two samples will be run
through testing at a given time. In most cases, the second or third sample shall not be secured within a chassis or
platform case, as this sample may be used specifically for mechanical testing.
Prior to execution of any testing on a port multiplier, a “worst port” must be identified. The intent of identifying a worst
port is not to validate each port to the specification, but to simply identify the worst port based on a single relative
measurement across all ports within a port multiplier. The Interoperability Tests shall, at a minimum, then be
executed on the worst port identified per the procedure below.
Power-on port multiplier and ensure test ports are enabled & functional. Run the following on each individual
port.
o If it is a device port, connect a device and complete OOB sequence
o If it is a host port, connect a host and complete OOB sequence
o Execute and record results for the typical Total Jitter (TJ) measurement using LBP while the host is in
NRZ idle following OOB
The “worse port” is identified as that which has the highest TJ value recorded on the measurement above
Relative to the Interface Power Management tests (see section 2.18), it is expected that the host product
manufacturer supply a facility (software, or hardware automation) which will initiate power management state requests
in order to support host-initiated test execution this is only required if the host product claims support for the host-
initiated power management capability.
