As part of the Universities Medium Voltage Infrastructure Upgrade Project there will be a loss of power to the Lloyd Building which will affect the Data Centre on the following dates:
- 8pm Monday 28th August until 06:45am Tuesday 29th August, 2017 (10 hours 45 minutes duration)
- 6pm to 9pm Monday 4th September 2017 (3 hours duration)
This loss of power will necessitate the powering off of all affected equipment in the Lloyd Data Centre in advance of those times. It will take us some time to return all services to production once power is restored. We apologise for the inconvenience that this necessary work will cause.
The following clusters are hosted in the Lloyd Building Data Centre and will be affected by this power outage:
Reservations have been placed in the queue's on each of the clusters as follows:
- 8am on the 28th of August until 9am on the 30th of August.
- 8am on the 4th of September until 5pm on the 5th of September.
The length of the downtime is required due to the considerable amount of time needed to power down and back on all systems in the Data Centre, not just the cluster, and ensure they have returned to service properly. We would hope to return the clusters to service as soon as possible after the outages.
This loss of power will also result in the network maintained by Research IT on the 2nd floor of the Lloyd Building and the small number of network ports in the CRAN building that are on the Research IT network being unavailable during the power outages.
DRIS - Digital Collections
The infrastructure that hosts Digital Collections, part of DRIS in the Library will have the following downtime windows:
Downtime Window 1: 1pm Monday August 28th 2017 until 1pm Tuesday August 29th 2017. With a further "At Risk": 2pm to 5pm Tuesday August 29th 2017.
Downtime Window 2: 1pm Monday September 4th 2017 until 1pm Tuesday September 5th 2017. With a further "At Risk" until 5pm Tuesday September 5th 2017.
Research Office Shared Drives
The Research Office Shared Drives are not expected to be affected by these power interruptions and should remain available. However, due to the nature of the works the Research Office Shared Drives should be considered "at risk" for these periods as they will be operating with reduced resilience.
