the new Maths server room

... and today, December 2016

Although it does look decidedly air-brushed and squeaky clean, the picture on the left is unretouched and was taken about one month after a new dual air conditioning installation was completed in April 2013. There were about 50 servers in the room at that time. On the right is the server room as it is today, December 2016 just before Christmas, after the completion of an air conditioning upgrade in September to add two more cooling units bringing the total to 4. There are now 160 operational servers in the room, with another rack and additional UPS units on the right, just out of the picture and for historical reasons, another 38 servers are located in the central college data centre.

For a concise overview of the research computing facilities offered by the Mathematics Department. please visit the Research Computing Support page on the main Maths website. The sysnews website is intended for those who already know of these facilities and want to know how to use them.

Continually updated, the pages you'll find here contain useful information about the Linux and UNIX-based IT services and facilities available to the research community in the Department of Mathematics. Admittedly, these pages are heavily biased towards these operating systems since most research is done on Linux or FreeBSD platforms but we would welcome suggestions on ways in which these pages can be expanded to include support for Windows and Macs.

Getting support

Support for all those using Maths research IT facilities is vital since without it, not a lot would get done. For this reason, providing timely and comprehensive support is taken seriously - it is available most of the time including weekends and out of hours simply by emailing Andy Thomas or call Mobex extension 59687.
