NPort ID Virtualization (NPIV)

Our Solaris QE team has been developing the test strategy for NPort ID Virtualization (NPIV). The i-team has already released the NPIV beta release in January.

Project status is here and here.

Here's a brief Wikipedia entry on NPIV.

COMSTAR: Common Multiprotocol SCSI Target

One of the new Solaris Storage projects that our test development team is currently implementing test infrastructure for is called COMSTAR. The overview of the project from the OpenSolaris.org COMSTAR page is:

COMSTAR is the software framework to use a Solaris host as a SCSI Target platform. COMSTAR uses modular approach to break the huge task of handling all the different pieces in a SCSI target subsystem into independent functional modules which are glued together by the SCSI Target Mode Framework (STMF). The modules implementing functionality at SCSI level (disk, tape, medium changer etc.) are not required to know about the underlying transport. And the modules implementing the transport protocol (Fibre Channel, iSCSI etc.) are not aware of the SCSI level functionality of the packets they are transporting. The framework hides the details of allocation, providing execution context and cleanup of SCSI commands and associated resources and simplifies the task of writing the SCSI or transport modules.

COMSTAR features include:

  • Extensive LUN Masking and mapping functions.
  • Multipathing across different transport protocols.
  • Multiple parallel transfers per SCSI command.
  • Scalable design approach.
  • Works with generic HBAs.

OpenSolaris Test Farm

Everyone in the OpenSolaris community should read about the OpenSolaris test farm that Solaris Quality Engineering is highly involved in.

I'm very excited about this test farm. It will be a very useful tool to many OpenSolaris contributers.

CTI for TET

If you're interested in one of the test frameworks we are using in the Solaris quality engineering organization, or if you are doing development and testing on OpenSolaris, this resource on CTI for TET should be of interest to you.

CTI stands for Common Test Infrastructure and is the set of tools and infrastructure you can use for OpenSolaris testing support. TET, which comes from the Open Group, stands for Test Environment Toolkit, which takes care of the administration, reporting, and sequencing of tests.

It's also great to see that some of of my team here in Sun Beijing ERI recently have been listed on the roster of OpenSolaris community test leaders.

Gantt chart generation on Solaris x86

I've started using a very nice native Gantt chart creation tool that runs well on x86 Solaris. The tool is Planner and I got it from blastwave.org, a good site for getting x86 Solaris binaries.

My major complaints about this tool are:

\* it doesn't generate PERT charts
\* when you export HTML, the x-axis of the Gantt chart lacks date labels
\* in the program view of the Gantt chart, the x-axis is labeled with "week 1", "week 2", etc., rather than actual dates
\* the PDFs it exports are viewable by Gnome PDF reader, but Acrobat reader shows many "square" characters and no actual text

Other than that, I'll continue to use it since it's the best option so far. The Java-based tool that I tried out, GanttProject, had too many problems, including exporting of HTML and PDF files.

I also looked at dotProject and Achievo, which are PHP-based tools that might be better suited for project management for a large project or a small company.

Open source Java application for Gantt charts

I'm a big fan of Gantt charts as a project management and planning tool. I've looked around for open source Gantt chart generation tools, and the one I like the most, concept-wise, is GanttProject.

I'm still working through some problems getting some features to work, like saving HTML or JPG exports on the Java WebStart version, and in resolving some java.util.ResourceBundle.throwMissingResourceException errors when running a version of the program I compiled myself.

When I am able to get this tool to successfully export HTML and JPG Gantt charts, I would rate it highly. If they can incorporate a feature to allow generation of PERT charts from the Gantt data, that would be very useful.
