Introduction
Read this case study from Riello UPS. It explores how a data centre in an old military underground bunker makes a move to Multi Sentry (MST) .
Key Challenges
Authorised Riello UPS reseller and service partner Specialist Power Systems is a long-standing supplier for Cyberfort, having looked after the UPS at both their sites in Kent and Newbury since 2008.
They were asked to specify a replacement, but the unique installation environment threw up several significant challenges.
The data centre is housed in a bunker 5 metres underground with only a relatively small opening available to lower the equipment into place, while each item couldn’t exceed a 1,000 kg lifting beam rating.
Delivering exceptional performance and up to 96.5% efficiency in one of the most compact footprints in its category made the transformer-free MST the ideal fit.
The 6 x end of life UPS would be replaced with 4 x 100 kVA MST units connected in parallel to deliver 300 kVA N+1 redundancy.
The Solution
Due to the complex nature of the installation environment, the replacement was staggered over a 12 month period involving substantial electrical works, such as 2 new 630A electrical supplies from A and B substations. This involved running infrastructure more than 100 metres and trenching new low voltage cables 85 metres.
However, the new Multi Sentry UPS are already proving their worth, with the enhanced efficiency already cutting the data centre’s electricity costs by around £32,000 a year.
