New Tech that will Transform Your Data Center<\/p>\n
It\u2019s clear that lithium ion (Li-ion) batteries stand poised to deliver some dramatic changes to the field of data center uninterruptible power supplies (UPSs), mainly due to their longer lifetime along with reduced weight, footprint and cooling requirements compared to lead-acid batteries that are commonly used in UPSs today. Let\u2019s paint a picture of just how dramatic that change might be in small to medium-size data centers.<\/p>\n
For starters, valve-regulated lead-acid batteries (VRLA) take up significant space. This is one of the reasons why large, or even medium-size companies, typically don\u2019t place them in the IT \u201cwhite room.\u201d Many organizations in recent years have been raising the temperature of their data center server rooms to save on cooling costs, keeping in line with\u00a0guidance from organizations such as ASHRAE (the American Society of Heating, Refrigerating and Air-Conditioning Engineers). IT equipment and UPSs can tolerate the higher temperatures just fine. VRLA batteries, on the other hand, will age and die prematurely at those higher temperatures.<\/p>\n
For all of these reasons, companies tend to create battery rooms specifically to house their VRLA batteries. Li-ion technology promises to enable a dramatic reduction in the size of these rooms, by a factor of 2 to 3, simply because Li-ion batteries pack so much more energy into a much smaller footprint. This will increase the footprint available for IT space while also reducing cooling requirements, which saves on both capital costs and ongoing operating costs.<\/p>\n
In some instances, Li-ion batteries may obviate the need for separate battery rooms altogether, by enabling batteries to be installed in the IT room along with the UPS. This is especially likely for small- to medium-size data centers. The strategy frees up useful space, simplifies installation and positions the UPS and associated batteries closer to the IT load, which provides better protection from any potential upstream electrical issues.<\/p>\n
Similarly, companies that use scalable and adaptable integrated data center architectures could benefit further from Li-ion technology. With such architectures, IT racks, power and cooling components are built and tested as part of an integrated data center solution which can then be expanded as necessary over time. Li-ion batteries will make these integrated \u201cpods\u201d even more space- and energy-efficient than they already are, while delivering the same benefits associated with having the UPS\/battery combination close to the IT loads they protect, and easily scalable to keep up with data center growth.<\/p>\n
In addition to reducing space and energy requirements, Li-ion batteries last twice as long and require less maintenance than their VRLA counterparts. They also come with advanced battery monitoring systems (BMS), giving IT groups easy, remote access to a reliable measure of the \u201cstate of health\u201d and \u201cstate of charge\u201d for their batteries. And with less maintenance to perform, that means fewer non-IT people need to be in the data center, which addresses a constant concern for IT groups.<\/p>\n
We expect to see great improvement in smaller, single-cabinet UPSs thanks to the combination of higher density power electronics and Li-ion batteries. A cabinet that today supports about 60 kVA with 10 min of energy storage with VRLA batteries, may one day protect 150-200 kVA with that same 10 min. of storage using Li-ion batteries, effectively more than doubling its power density. Such density improvement should substantially change the old knock against UPSs, that they\u2019re \u201cnecessary but bulky.\u201d<\/p>\n
With this paradigm shift, it is also not difficult to imagine more power protection integrated right into IT racks, because it will take up far less space and require dramatically less frequent maintenance.<\/p>\n
These are just a few of the ways Li-ion batteries may change the 3-phase UPS landscape in data centers in coming years. We would love to hear your feedback and take on the topic, so feel free to share with us using the comments below.<\/p>\n","protected":false},"excerpt":{"rendered":"
