The INCITS Fibre Channel (T11) Technical Committee is soliciting
technical contributions to the SM-HBA-2 project. See www.t11.org,
"documents" T11/06-065v3 for the project proposal defining the
scope of the project. Contributions will be considered at the
next meeting of the SM-HBA-2 adhoc group during the June 2008
T11 committee meetings. Clause 3.1 says:
"A standard application programming interface (API) defines
a programming language by which control can be
specified for certain features of a computing system,
independently of vendor-specific infrastructure behavior.
A host bus adapter (HBA) is a piece of hardware, typically
on a host system and sometimes embedded on a RAID
controller or other storage device that interfaces between
a system and a storage access medium. An HBA and
the medium to which it provides access may also support
applications other than storage, such as delivery of
Internet Protocol (IP) packets.
The Storage Management Host Bus Adapter Application
Programming Interface (SM-HBA) standard defines an
API for Fibre Channel and SAS HBAs. The Storage Management
Host Bus Adapter Application Programming
Interface 2nd generation (SM-HBA-2) project proposal
recommends the development of additions and enhancements
to SM-HBA to support new features of Fibre Channel and SAS
that have matured during the development of
SM-HBA. The following capabilities should be included in
the SM-HBA standard:
a) Administration and operation of Fibre Channel
additional N_Port_IDs, also known as N_Port ID Virtualization
(NPIV);
b) Administration and operation of Fibre Channel Virtual Fabric
connectivity;
c) Administration of fabric security features specified
for storage networking media supported by the
standard;
d) Consider opportunities for administration and operation
of HBA virtualization models being developed in
other standards;
e) Consider opportunities to extend consistent administration
and operation to other storage networking
media;
f) Other capabilities that may fit within the general scope of this
project;
and
g) Binary compatibility with applications written for one or
more predecessor specifications of the standard."
