As South African increasingly faces continuous load shedding, Pinnacle Micro has announced that it can save users up to 50% on energy by making use of its Supermicro high-efficiency power supplies and Western Digital "green" power disk drives.

Pinnacle Micro is the official local distributor for both Western Digital and Supermicro. Western Digital is one of the world’s leading hard disk distributors, while Super Micro Computer is a leader in application optimised, high-performance server solutions.
Shane Hutchison, brand manager of Western Digital at Pinnacle Micro, says the high performance drives use “half the power of normal drives”.
“With the energy problems facing South Africans thanks to Eskom’s lack of capacity and financially draining load shedding, the need to save energy consumption is now far more critical. If Eskom cannot build more capacity in the next few years, we, as users, are going to have to cut down on usage.”
He says the ‘green’ seven watt drives – which are enterprise-class drives – are now available locally. “Sales are booming and we certainly believe that this is going to continue as long as we are facing power problems in this country.”
Meanwhile, Pinnacle Micro’s Supermicro brand manager Francois Lottering, says that since the end of 2006 all of  Supermicro’s power supplies have been high efficiency, with ratings of over 85%. These power usage ratings frequently reach 93% on the Supermicro Twin and Supermicro Superblade.
“Research done by Supermicro shows that users can gain big power savings by utilising high efficiency power supplies. Over the three- to four-year lifecycle, a saving of up to $8 000.00 can be made on some blade configurations.”
He says research shows that data centres in the US consumed about 61-million kilowatt-hours (kWh) in 2006, roughly 1,5% of total U.S electricity consumption – or about $4,5-billion in electricity costs.
Existing technologies and strategies could reduce typical server energy use by 25%. Even greater energy savings are possible with advanced technologies.
Lottering says 61-billion kWh equates to 39-million tons of C02. A saving of only 3,89kg of CO2 would equate to one passenger car not being driven for one year, one household turning off its power for six months and more than 10 barrels of oil not burnt, says Lottering.
