Silicon Graphics SGI Challenge S

The Challenge S is SGI’s entry level server. It is essentially an Indy, with some key parts removed, and some added.

The Challenge S is designed to run as a headless server – as such, it has no ports for a keyboard, mouse, or video out. It also lacks the S-Video in and IndyCam in ports that the Indy has, and also has no sound.

The other main difference is that the primary ethernet port on the Challenge S is AUI – on the Indy it is 10-BaseT. This means that you’ll need to get an AUI transciever if you want to connect to a 10-BaseT or 10-Base2 network on the primary port. However, the Challenge S does come as standard with the Mezzanine SCSI board.

This is a single height GIO board, with 2 fast-wide-differential SCSI ports (providing 2 seperate channels) and a 10-BaseT ethernet port.

Serial port A is where you should plug in a serial terminal to administer the machine. This is deemed the ‘console’ port. I’ve used everything from wretched old VT100 terms, through console networks, to a Palm Pilot.

As it’s based on the Indy, upgrades are very easy. The Challenge S will take the same memory, hard drives, and CPU modules as an Indy. As it shares the same PROM, it could even be configure to have the console as a graphics card. There is room to fit one, even with the Mezzanine card fitted.

More information can be found on the Indy model summary page.

Summary:

  • Max. 256mb RAM, as in the Indy

  • No keyboard or mouse port

  • No graphics card, so no monitor

  • No Video input, and no sound
