PC2 - Protocol Control Control

Introduction
The PC2 software from SCSI Toolbox, LLC brings a new level of parallel SCSI protocol control to your test environment. Designed in cooperation with LSI Logic to work with their Fusion-MPT™ Message Passing Interface technology, PC2 allows all negotiated parameters to be displayed or set for all devices connected to any SCSI Host Bus Adapter based on the LSI53C1030 chip set. PC2 also provides the means to generate hardware SCSI bus resets.

If your testing requirements demand complete control over transfer speeds, data width, or any other negotiated parameters, PC2 and an LSI based HBA is the easy to use and inexpensive solution you have been waiting for!

As described below, PC2 is two complete software products in one.

The Stand Alone PC2 program
First, an easy to use GUI allows quick access to view or change device parameters. Here is a screen shot of the PC2 interface displaying all connected devices. The user simply double-clicks on the device that he is interested in working with:

Once a device is selected, all negotiated parameters are displayed. Any of these parameters can be changed, or one of the pre-defined choices may be used to set either the selected device or all connected devices to the new settings.

In the screen shot below, the selected device is currently set to operate at Ultra 160 speed

By simply clicking on the Fast-10 button this drive will be set to operate at 10MB/sec narrow SCSI speed, as shown below

Here is a SCSI bus trace showing exactly what occurs when this button was clicked:

Clicking on the Fast-320 button causes the following bus transaction:

Notice the SCSI Bus Reset that occurs at event 148 in the trace above. This reset was generated by simply clicking on the “Reset SCSI Bus” button on the PC2 GUI.

The PC2 GUI application is an independent application program which can be run and used in conjunction with any other diagnostic or test program.

The PC2 Function Call API

All of the functionality of PC2 is accessible via function calls through the SCSI Toolbox Developer Toolbox (DTB) software package. A programming library accessible by Microsoft Visual Basic or Visual C++ programming, DTB offers complete access to all of the PC2 feature set. High Level functions allow the programmer to easily set all parameters to any transfer rate combination, or any individual negotiated parameters may be read and/or changed. In addition hardware SCSI Bus Resets may be generated.

PC2 and the Real World

Here is a screen shot of a disk write test, where is PC2 used alongside the SCSItoolbox to change the negotiated transfer rate for the drive as the test is running!:

Summary:

• total real-time protocol control
• complete compatibility with other programs
• Easy to use GUI
• Programming API
