Clusters Downtime June & July 2019

Submitted by smcgrat on Tue, 06/04/2019 - 15:20

There have been problems with some of the equipment that provides cooling for the Lloyd Building Data Centre over recent months. Estates and Facilities are planning to carry out significant remedial works over the coming weeks which will hopefully resolve those problems and make the cooling system for the data centre more resilient in the future.

(Edited June 28th with updated July downtimes).

Unfortunately this will necessitate some long downtimes for the clusters hosted in the Lloyd Data Centre.

The following Clusters will be unavailable:

  • Kelvin
  • Lonsdale
  • Parsons
  • The TCIN mini cluster

Between the following times:

  1. From 7am until 6pm of Monday 10th of June 2019.
  2. From the afternoon of Tuesday 9th of July 2019 until the afternoon of Monday 15th of July. (If possible we will return the clusters to service on Friday the 12th but we cannot guarantee that).

We apologise for any inconvenience these necessary service interruptions will cause and thank you for your patience.

Note: The previously advised July downtime was from the afternoon of Monday 1st of July until the morning of Monday 8th of July. This had to be changed due to a delay by the manufacturer of the new equipment needed. This is beyond our control unfortunately.

We will do our best to keep you advised of any other changes to this schedule if any occur.

IT Services License Server Downtime

Submitted by smcgrat on Tue, 06/04/2019 - 12:17

To facilitate essential maintenance, the License Server administered by IT Services which provides licenses for the following applications used on the Research IT Clusters will be unavailable.

  • Matlab
  • Mathematica
  • Ansys

It will not be possible to check out new licenses for those applications from 8am Thursday 6th of June 2019 until 11am the same day. There will be a further "at risk" period for the rest of the working day during which the licenses may be unavailable in the unlikely event that remedial actions are necessary. Licenses checked out in advance of the downtime should remain valid.
