If you’ve been following this blog in the last couple of weeks you’ll have noticed that I have profiled a couple of data centre energy management companies – well, today it is the turn of Power Assure.
The last time I talked to Power Assure was two years ago and they were still very early stage. At that time I talked to co-founder and CTO, Clemens Pfeiffer, this time I spoke with Power Assure’s President and CEO, Brad Wurtz.
The spin that Power Assure put on their energy management software is that, not only do they offer their Dynamic Power Management solution which provides realtime monitoring and analytics of power consumption across multiple sites, but their Dynamic Power Optimization application automatically reduces power consumption.
How does it do that?
Well, according to Brad, clients put an appliance in each of the data centres they are interested in optimising (Power Assure’s target customer base are large organisations with multiple data centres – government, financial services, healthcare, insurance, telco’s, etc.). The appliance uses the management network to gather data – data may come from devices (servers, PDU’s, UPS’s, chillers, etc.) directly, or more frequently, it gathers data directly from multiple existing databases (i.e. a Tivoli db, a BMS, an existing power monitoring system, and/or inventory system) and performs Data Centre analytics on those data.
The optimisation module links into existing system management software to measures and track energy demand on a per applications basis in realtime. It then calculates the amount of compute capacity required to meet the service level agreements of that application and adds a little bit of headroom…
