Servers Designed for Immersion (SDI) – An Alternate Approach
If you’ve already implemented or are considering a “white box” solution – building your own servers – or you want to truly maximize space, power and budget, then SDI may be your best choice.
Immersion cooling technology addresses the key concerns of thermal design and hardware reliability that are common with air-cooled, white box servers. Further, engineering purpose-built servers from the ground up allows more than just design them for cost and performance, but also for space and power utilization.
Key Benefits of Servers Designed for Immersion:
-
Purpose-built for application
-
Mix and match components without worrying about thermal design limitations and reliability
-
No extraneous components, such as integrated fans, heat sinks and oversized power supplies, reduce cost and e-waste
-
More power-efficient – up to 30% lower energy use vs air-cooled servers
-
Maximized rack density with simplified, modular chassis that utilize much higher immersion cooling capacities
SDI are an ideal match for micro-modular, rack-based immersion cooling system and immersion-cooled, modular data centres.

Transport Fuel Duty and Heating Fuel Duty
Firstly, looking at these tables, one wonders at the logic applied by those Civil Servants to arrive at such numbers? Was it a gallons to litres issue? Who can tell.
With the reduction of 5p on Petrol and Diesel it must be stressed that LPG, CNG and LNG powered vehicles already had a big advantage in respect of “fuel duty” and have further been slightly reduced in this year's budget too [see table]. With Natural gas /bio gas at less than 50% [42.6% in fact] of even the new Petrol/Diesel duty. Also LPG [Liquefied petroleum gas] is only 54.5% of the ‘normal’ [petrol/diesel] fuel duty.
Also please note the Bio-diesel and Bio-ethanol both attract FULL duty per litre. This makes little sense given the processes involved to create these fuels – although growing crops to make these is not ideal.
