A few days ago Google released its new service “Google Drive” to the general public. It stores your documents and files in the cloud – like many other services on the market. And it is one step further in the general adoption of cloud based infrastructure.
This leads to the question if there is any special guidance needed on powering the cloud. In the recent issue of DatacenterDynamic’s FOCUS magazine dedicated to cloud infrastructure, Chris Loeffler of Eaton Power gives some helpful advice on what to consider for powering your cloud. His words make clear that cloud computing poses unique power, cooling and availability challenges.
In this blog post we just focus on his recommendations concerning the UPS infrastructure. You can find the rest of his insights after the link below.
“Modular Uninterruptible Power Supply (UPS) systems let you add capacity quickly and incrementally. A modular scalable UPS for a small cloud environment may provide up to 50kW or 60kW of capacity in 12kW building blocks that fit in standard equipment racks. IT personnel can simply plug in another 12kW unit, growing capacity (in this example) from as little as 12kW up to 60kW N+1.”
“Add redundancy to your power architecture: N+1: An N+1 architecture includes one more UPS, generator or other power component than the minimum required to keep server equipment up and running. An N+1 architecture is often sufficient for the needs of a small or medium cloud environment.”
