title: That one lasted for eight hours UPS, Saved the entire data center, It also changed our view on backup power 2022 Late autumn, The self built computer room of an Internet enterprise in Hangzhou was unexpectedly powered off. After the mains power trips, Diesel generator failed to start normally, The on duty engineer stared at the slowly decreasing remaining battery level on the monitoring screen, My palms are covered in sweat. Originally only equipped 15 The Traditional Minute Battery Capacity UPS system, In terms of load capacity, only 30%In the case of, After barely holding on for less than ten minutes, it was completely depleted. Data write interrupt, A large number of bad pages appear in the database, It took a whole weekend to recover. And during the same period, Another company's deployment of dynamic support in North China UPS system, Continuous power supply for more than eight hours after a power outage in the city, Wait patiently until the diesel engine repair is completed, Zero Service Interruption. Both are backup power sources, The gap is a world of difference. frankly speaking, tradition UPS Following the design concept is "Anti power outage" rather than "Everything after power outage prevention" . The standard configuration usually only meets a backup time of a few minutes to half an hour, Default reliance on diesel generator system as subsequent support. This logic was considered reliable ten years ago, But in reality, The failure rate of diesel engine start-up is not low. let alone, Many small and medium-sized computer rooms do not have the conditions for diesel generators. Once the mains power is interrupted, a trip occurs, oil passage blockage, Difficulty starting due to low temperature, That pitiful battery backup time became a tragic countdown. Dynamic holding UPS The core idea is completely different. It no longer sees the remote generator as an inevitable savior, But rather seeing oneself as genuine "Endurance unit" . Through high-density lithium battery packs and intelligent power management, Dynamic holding UPS can 40%Under the load capacity, Extend the backup time to 6 to 8 Hours or even longer. This is not a simple battery expansion, But rather a redefinition of the power architecture. Long standby power means you can easily arrange maintenance windows, Instead of completing fault diagnosis within ten minutes, Tram dispatch, Switching operation is a series of high-pressure actions. Re accounting from a cost perspective, Dynamic holding UPS On the contrary, it is more convincing. a set 15 The tradition of backup power in minutes UPS Adding the procurement of diesel generator sets, Install, operational costs, The total cost of ownership over three years is often higher than that of a long-term backup power supply UPS. The generator requires regular load testing, Oil replacement, Exhaust pipe maintenance, These implicit expenses are often overlooked. And the cycle life and maintenance free characteristics of lithium batteries, Coincidentally bridging this part of the ongoing investment. look back, The backup power solution for data centers is moving towards differentiation: Either it is the high maintenance mode of traditional short standby power plus generator, Either it's a long-term backup electric vehicle UPS Simplify the low dependency mode of the generator. For small and medium-sized enterprises lacking dedicated operation and maintenance personnel, frankly speaking, The latter brings not only technological convenience, It's more about psychological safety. A dynamic holding device UPS, Hold on for eight hours, Survived a data center crisis. This is not a victory of technical parameters, But rather the awakening of backup logic.
