Development *** THIS IS NOT A FINAL DRAFT *** SFF-8087 Rev 2.1SFF Committee documentation may be purchased in hard copy or electronic form. SFF specifications are available at ftp:// CommitteeSFF-8087 Specification forMini Multilane Series: UnshieldedRev 2.1 September 7, 2006Secretariat: SFF CommitteeAbstract: This specification defines the physical interface and general performance requirements for the Unshielded Mini Multilane connector that is designed for use in high speed serial interconnect applications at speeds up to 10 Gigabits/second. One such use is as the Serial Attached SCSI Mini SAS 4i (wide compact internal connector).This specification provides a common reference for systems manufacturers, system integrators, and suppliers. This is an internal working specification of the SFF Committee, an industry ad hoc group.This specification is made available for public review, and written comments are solicited from readers. Comments received by the members will be considered for inclusion in future revisions of this document.The description of a connector in this specification does not assure that the specific component is actually available from connector suppliers. If such a connector is supplied it must comply with this specification to achieve interoperability between suppliers.Support: This specification is supported by the identified member companies of the SFF Committee.POINTS OF CONTACT:Jay NeerMolex2222 Wellington CourtLisle, Il 60532I.

The membership of the committee since its formation in August 1990 has included a mix of companies, which are leaders across the industry.When 2 1/2" diameter disk drives were introduced, there was no commonality on external dimensions e.g. physical size, mounting locations, connector type, connector location, between vendors.The first use of these disk drives was in specific applications such as laptop portable computers and system integrators worked individually with vendors to develop the packaging. The result was wide diversity, and incompatibility.The problems faced by integrators, device suppliers, and component suppliers led to the formation of the SFF Committee as an industry ad hoc group to address the marketing and engineering considerations of the emerging new technology.During the development of the form factor definitions, other activities were suggested because participants in the SFF Committee faced more problems than the physical form factors of disk drives. In November 1992, the charter was expanded to address any issues of general interest and concern to the storage industry. The SFF Committee became a forum for resolving industry issues that are either not addressed by the standards process or need an immediate solution.Those companies, which have agreed to support a specification, are identified in the first pages of each SFF Specification. Industry consensus is not an essential requirement to publish an SFF Specification because it is recognized that in an emerging product area, there is room for more than one approach. By making the documentation on competing proposals available, an integrator can ex。
