6、ended to be used assuch.INCITS Technical Reports are produced in some cases to disseminate thetechnical and logical concepts reflected in standards already published or underdevelopment. In other cases, they derive from studies in areas where it is foundpremature to develop a standard due to a still

Processing by INCITS is also similarto that for a draft standard.PatentStatementCAUTION: The developers of this Technical Report have requested

33、s strongly recommended”.INCITS TR-39-2005103.7 Applicability and Use of this Technical ReportThis technical report specifies which features shall be used (i.e., required) and which features shallnot be used (i.e., prohibited) by interoperating compliant Fibre Channel implementations. Use ofsome feat

34、ures is optional (i.e., allowed). The use of such functions is either negotiated in a fixed andstandard manner or the availability of the functions for use shall be determined in a standard manner.The relationship between use as specified in this technical report and support as implemented by aprodu

35、ct is subtle. If this technical report specifies that a feature shall be used, then a compliant imple-mentation shall support it. In some cases, this technical report is asymmetric: to ensure interoperabil-ity when an optional feature is used, this technical report requires support for the infrastru

36、cturerequired to use the feature without specifying that the feature be used to conform to this technical re-port.The requirements of this technical report are a proper subset of the various relevant standards. Thistechnical report prohibits use of many features and options in these standards. Use o

37、f prohibited fea-tures may prevent interoperability with Fibre Channel devices complying to this technical report. Thistechnical report does not prohibit implementation of features, only their use. Functions that are man-datory in the appropriate base standard are assumed to be implemented. Implemen

38、tations may sup-port features whose use is prohibited by this technical report and such prohibited features may berequired for compliance with the relevant standards or other technical reports.3.8 Feature Set Table Terms, Definitions, and Abbreviations3.8.1 OverviewFeatures in this technical report

39、are summarized in the form of Feature Set tables. These tables indi-cate whether the feature is Required, Prohibited, Invocable, or Allowed for compliance with this tech-nical report; or whether a parameter is Required to be a particular value for compliance with thistechnical report. Features or pa

40、rameters that are not listed do not affect interoperability.In several tables within this technical report, there are references to notes associated with the table.These notes are normative and are mandatory requirements of this technical report.INCITS TR-39-2005113.8.2 Feature Set Table Terms and D

42、 terms and definitionsTerm DefinitionProhibitedA feature that shall not be used between Fibre Channel devices compliant with this technical report. An implementation may use the feature to communicate with non-compliant implementations. This technical report does not prohibit the implementation of f

43、eatures, only their use between Fibre Channel devices compliant with this technical report. Use of a prohibited feature may prevent interoperability with Fibre Channel devices complying to this technical report.RequiredA feature or parameter value that shall be used between all Fibre Channel devices

44、 compliant with this technical report. Fibre Channel devices compliant with this technical report are required to implement the feature. An implementation may use the feature to communicate with non-compliant implementations. If a Fibre Channel device does not implement a required feature that devic

45、e may not be interoperable with Fibre Channel devices complying to this technical report.AllowedA feature or parameter value that may be used between Fibre Channel devices compliant with this technical report. Fibre Channel devices compliant with this technical report are not required to implement t

46、he feature, but if they do, the feature shall be implemented as described in the applicable standard. The potential user of a feature may determine if the recipient supports that feature via a Required discovery process or a minimal response by the recipient.InvocableA feature or parameter that is r

47、equired to be implemented by a device to which a request may be sent, but it is not required to be used by a requesting device.Table 3 Feature Set table key abbreviationsKey DefinitionP ProhibitedR RequiredA AllowedI InvocableX This parameter has no required value; any value is allowed.- This parame

48、ter is ignored or this feature is not applicable.INCITS TR-39-2005123.9 Feature Testing ComplianceWhile not a compliance vehicle in itself, this technical report should be used as the basis for compli-ance testing. As such, the relationship for the definitions of Prohibited, Required, Allowed, and I

49、nvo-cable (see 3.8) to compliance testing is described in table 4.3.10 Timing ConstraintsAll timings defined in this technical report are meant to limit the amount of time a device takes to ac-complish a task. These timings shall be measured on an unloaded system. A heavily loaded systemmay exhibit timings in excess of those specified. The term unloaded means that system activity is in-duced only in direct invocation of the feature under test.Table 4 Feature testing compliance relationship to definitionsTerm DefinitionProhibitedA feature that
