Puretec Basic

[Vickiana Sconyers]

Gota switch zoneset configured from one of the FA-300s,which I have re-purposed as a server, to the FA-420 with Windows Server 2012 R2 and SQL Server 2012. Right now just doing some basic testing using direct attached SSD for a few upcoming demos then I will be switching everything over to boot from SAN.

One of the most important things to ensure you enable on the Windows Server 2012 R2 host is Multipath I/O (MPIO) to ensure you redundant physical connection support to the Pure Storage array. Without MPIO installed using Windows Computer Management/Storage/Disk Management you will see something like below, lots and lots and lots of drives. In my case 32 to be exact, the math [((4 redundant connections) x (2 controllers)) x (4 HBA ports)] = 32.

We work with the out-of-the-box Microsoft Device Specific Module (DSM) so you just need to make sure that the MPIO feature is added to Windows and then make sure that the PURE FlashArray is listed in the MPIO Properties. To add MPIO to Windows Server you can use one line of PowerShell:

Time to get back to work on configuring MPIO specifics, migrating my SQL Server database to the Pure Storage LUN and working on some PowerShell to take snapshots and create new hosts to mount those snapshots.

I would like to buy a Peugeot 2008 (2018 or 2019), with a 1.2 petrol engine. I quite like the car, with the only visible flaw being the small back seats. I plan to use it for light weekend driving and occasional long motorway journeys to the Continent with the kids.

What I don't understand is why they have three 1.2 L PureTech engines with very different power (80, 100, and 130 BHP). I plan to get a 100 BHP. What are the pros and cons of having such small but powerful engines? I come from a world where a 1.2 was sufficient for small cars, not 1.6 ton SUV.

Second, as far as I can tell, the 1.2 PureTech that age of 2008 would have had either 110bhp or 130bhp, not 100bhp (though the 1.5 diesel has 100bhp). The different power outputs are because people have different requirements regarding performance, not sure what is so complicated about that?. Back in the old days, you might have had a 1.0, 1.3 and 1.6 option on the same car depending on how much performance the buyer needed/wanted/could afford, this is the same thing, but using the same basic engine. BTW, the two higher power versions are turbo, the lower powered one is not.

COOLING IS essential for various reasons within an industrial setting. Maintaining specific temperature conditions is crucial for product quality and operational efficiency. The journey from traditional cooling methods to modern innovations has been pivotal. Traditional methods relied on less sophisticated techniques compared to the innovations available today.

Water-based cooling systems, for instance, used large quantities of water circulating through pipes or channels to absorb heat from machinery or processes. The heated water was then redirected to cooling towers or other systems to dissipate the heat and lower the temperature before recirculation. Other methods, such as basic air ventilation and fans, were used to mitigate heat build-up. However, this method had limitations, especially in larger spaces or where precise temperature control was required.

Chillers work on the fundamental principles of thermodynamics and the refrigeration cycle. They transfer heat using a refrigerant that alternately absorbs and releases thermal energy through changes in pressure, temperature and phase (liquid to gas and vice versa).

Improving heat transfer mechanisms involve optimising the design of heat exchangers, coils and the refrigeration cycle. Increasing heat exchange surface areas, using more efficient refrigerants, enhancing compressor technologies and employing advanced control systems can help to maximise efficiency and performance.

The 30KAVIZE meets the most demanding expectations in terms of energy efficiency and savings - both financial and space. The 30KAVIZE has a significantly smaller footprint compared to other models with the same capacity, approximately saving 3 metres in length.

Furthermore, the 30KAVIZE operates at ambient temperatures of -20C to 55C and offers excellent energy efficiency. It has an average Seasonal Energy Efficiency Ratio (SEER) of 5,0 and a Seasonal Energy Performance Ratio (SEPR) of up to 3,7 (the ratio between annual cooling demand and annual energy input), which is 25% higher than EU Ecodesign requirements.

Taking advantage of naturally occurring lower outdoor temperatures is another way industrial cooling processes can become more efficient and cost-effective. When the outdoor air temperature is sufficiently lower than the required cooling temperature, for instance, during the winter or at night, it becomes an ideal source for cooling.

In many industrial processes, there is room for improvement when it comes to utilising waste heat. In some industrial processes that run 24/7, an absorption chiller can capture waste heat such as steam or hot water and can recover and reuse it within the same process or other parts of the facility where it may be needed.

This heat recovery therefore improves the cooling process by lowering the need for additional energy input which further enhances the overall energy efficiency, reduces operational costs and minimises the impact on the environment.

With the introduction of F-gas regulations in 2020, which phases down and phases out certain refrigerants with high GWP, Carrier responded responsibly and manufactured its own screw chillers that operate on HFO (hydrofluoroolefin) R-1234ze refrigerant.

Inside the 30KAVIZE, for example, the R-1234ze refrigerant has a 40% reduction in refrigerant charge thanks to its Novation micro-channel heat exchangers, offering energy efficiency gains of up to 5% when compared with units using R-134A.

Ammonia is a commonly used refrigerant in industrial cooling processes. Although this natural gas has a GWP of 0, precautions need to be taken due to its toxicity. If the refrigerant has a fault or leak, it can be extremely hazardous to employees, and the facility may need to be evacuated, causing significant downtime to operations. Hence why HFO refrigerants are a more attractive option and more cost-effective.

Another benefit of a modern cooling system is smart controls. Being able to precisely control temperature at any given moment can be critical in certain industrial processes, such as food processing, pharmaceutical production or mechanical engineering.
