Previous issues include it not being able to send email alerts, constantly restarting, and losing communication with the UPS. The network interface on a new UPS unit would be far superior and reliable than the part in use. In other words, there is currently no good solution but to call it in and replace the part every time it acts up. |

Overview
uniPHARM uses a generator to provide power in the event of a hydro outage. As the generator requires time to start and become ready, there is a large UPS in the server room that provides the room and select outlets throughout the building with continuous power.
Design
The attached JPG is a diagram of how electric power is organized in the Server room. The rack closest to the door and the middle rack are fed power from the Liebert UPS which filters power from Hydro or in the event of a Hydro failure, the generator. The rack farthest from the door containing the Power8 hardware has 2 different power feeds, one from the Liebert UPS and the other straight from Hydro. The second feed from Hydro plugs into the Power8 UPS at the bottom of that rack. The Power8 rack has each of its 2 feeds of power protected by a UPS so even if 1 UPS fails or drains, the other UPS will still provide electricity so that the Power8 will remain up. The only way that the Power8 system will go down is if both UPS's fail AND we have Hydro AND generator failure. Highly unlikely.
UPS
The main UPS is a Liebert APS unit (12kVA,with max capacity of 20kVA),The warranty included with the purchase of the device will expire in January 2026. There is an Eaton (400ish VA) UPS in the rack dedicated to the Power server and its related components (disk enclosure etc.)
The technical support number and account information for Liebert is on the top right side of the UPS.

Insights on the future of Liebert UPS
(Jan 2024) Unipharm updated the UPS equipment, and the current model is Liebert APS. Considering that the equipment in the IT room may be migrated to the cloud in the future, we reduced the UPS battery from 20KVA to 12KVA. However, this model of equipment is scalable. If necessary in the future, we can purchase battery modules to expand it to 20KVA.
