Computer Systems

This cupboard contains all the server computers we have at WHR, including the P-Squared "Myriad" playout system, our studio intranet servers and our station output logging controller. The majority are connected to a keyboard and monitor switch so that an administrator can work on any of them from the workstation on the left. The cupboard's in a bit of a mess at the moment as we're working towards launching a 24-hour-a-day service using the Myriad system, and our Engineers lead by Nigel Dallard are busy installing and configuring things.

The two computers on the second shelf down are our Myriad playout servers. They hold the music and programme library, and will provide our sustaining service when it is launched. The machines are configured as "main" and "standby", with auto fail-over provided using silence detectors. If both machines fail, we fallback to an emergency CD in the player to the left of the servers.

The two computers on the top shelf provide access to the computerised music library from the two studios. Their keyboards, monitors and mice will reside in the studios, and allow the presenter to select and play any music on the Myriad system.

On the third shelf, on the right we have an old 386 PC running "Logger" - a home-brew piece of software that monitors the "On Air" and "Mic Live" status of our studios, and triggers a cassette recorder to record our station output whenever a Mic is live in the On-Air studio. It can also record output at pre-determined times, irrespective of the Mic Live status. To the left are two other machines, both running RedHat Linux, that our Engineers are working on at the moment in the hope of adding a shared file-server for our office computers and access to the IRN news text service delivered via satellite.

On the bottom shelf, on the left we have our current main intranet server. This is a lowly 486-based machine running RedHat Linux. It provides our e-mail and internal website and DNS services. It exchanges mail with our ISP a couple of times each day, allowing us to send mail and to receive requests for patients from anywhere in the world. Next to it is our UPS, which keeps all the servers and other audio equipment up and running during a power cut - fortunately we only have to survive for a few seconds until the hospital's generator cuts in. Finally, on the right is our dial-up router/firewall that provides our internet access.
