Pure Storage platform is built specifically for flash storage. It bypasses the limitations of usual SSDs by talking to flash storage directly and leverages its strengths and reduce weaknesses. As a result it provides much higher storage density and performance. This also shows in significantly less energy needs, less physical space needs, and less production of e-waste than any other data storage provider. Our unique Evergreen architecture that extends equipment life up to 10y or more plays also significant part in this. 1) The attached graphics shows summary representing 85% energy and emissions savings.

Why are many afraid of GOOSE? Okay, maybe we should start from the beginning. What does the abbreviation GOOSE mean, and what is it? GOOSE stands for Generic Object Oriented Substation Event and is a protocol for data exchange within the #IEC61850 framework. But what does that mean? GOOSE traffic allows intelligent electronic devices (IEDs) to exchange data both "horizontally" between different bays of a substation and "vertically" between the process level and station level. It is typically used for exchanging status, interlocking and trip signals, and sometimes measurements. The main feature of GOOSE is that safety-critical signals, which were hardwired in classic substation design, can be exchanged via Ethernet-driven technology in a modern digital substation design. This means that instead of laying multiple copper cables between bays, a "simple" network can perform the same function, that should be everyone's dream, right? GOOSE messages are exchanged at layer 2 (data link layer) of the OSI model and utilize Ethernet's multicast functionality. Communication involves event-driven transmission, where the same GOOSE message is retransmitted several times in a row to ensure it is not lost. Upon the occurrence of a preconfigured event condition, an IED sends a GOOSE message containing the variable values that need to be communicated for that event. Since they are multicast, GOOSE messages are not acknowledged by the receiver; receivers simply subscribe to the message. Let's return to the original question: Why are many afraid of GOOSE? It might be because many have experienced implementations where small changes to the data model or functions in a single device meant that all devices at a substation had to be updated/reconfigured. This is naturally time-consuming and can be frustrating. Without stepping on anyone's toes, there is often a correlation between how GOOSE applications in a system are designed and how easy they are to maintain or update. Designing these applications can be complex, it's therefore important to create good bay typicals to avoid starting from scratch each time. I think it's a shame that the technology is often judged based on early versions/implementations, that might have been immature. At Eluminate, we can help organizations understand and build GOOSE applications and therethrough accelerate the expansion of power grids. The latest development in the GOOSE world, particularly R-GOOSE (Routable Generic Object Oriented Substation Event), which the #IEC61850 standard has supported for some time, is that the industry now has started to develop functionalities in IEDs that directly support R-GOOSE traffic between substations. I look forward to seeing how we as an industry can benefit from the flexibility of these functionalities and build cost-effective substations without compromising safety or security.

Overcurrent protection #ICs ensure efficient, safe & stable operation of power systems and are often used in energy storage. With the rise of #PMIC tech, protection features, including overcurrent, are increasingly integrated, offering cost & space savings. However, standalone ICs still have a place, meeting customization, scalability, cost control, and specific standards needs. The choice depends on design goals, budget, performance, and system architecture. #EnergyStorage #Tech

 From Security to Sustainability: The Dual Benefits of Space Saving Computer Cages As technology progresses at an unprecedented rate, the need for data centers to be sustainable and scalable has become increasingly important. I'm thrilled to say that Compu-Site Technologies is innovating a greener and more efficient future for our industry. The Co-Lo Cage isn't just another security system; it's a testament to what can be achieved when we prioritize both environmental responsibility and operational scalability. By integrating a welded wire mesh design, the Co-Lo Cage maximizes airflow while ensuring top-tier security, fundamentally remaining true to classic security but utilizing less than half the space.  Scalability is at the heart of Co-Lo Cage's design. Its ability to snugly fit around server racks, eliminating unnecessary dead space, significantly shrinks the data center's footprint. This efficient use of space not only boosts operational efficiency but is also a stride towards meeting our ambitious sustainability goals. The adaptable nature of the Co-Lo Cage, accommodating servers of various sizes, promises an ease of integration and futureproofing. This innovative approach allows for the same HVAC cooling units to serve a greater number of server units effectively. The design is elegant and simple, cutting down on space usage by over half without compromising on security, staying true to the essence of data protection while embracing the future of environmental consciousness. I invite my colleagues in the technology and sustainability fields to join us in this transformative journey. By adopting innovations like the Co-Lo Cage, we can collectively pave the way for a data center paradigm that is scalable, efficient, and profoundly green. #DataCenterRevolution #EcoFriendlyTech #SustainableInnovation #FutureIsGreen #TechForSustainability #ScalableSolutions #GreenDataCenters #EfficiencyFirst #EnvironmentalTech #InnovateForEarth #CoolingTechEvolution #ServerSecurity #SpaceEfficiency #TechForChange #GreenIT

🧐 Imaging buying a car and the manufacturer claims it consumes 0.1L per 100km? You'd raise an eyebrow, right? We all know cars (sadly) typically consume between 5 and 15L per 100km. Well, similarly, not knowing the energy consumption of a physical server is like handing over the reins to carbon calculators to throw any number at you: starting with a server where we have no ballpark figure of its consumption, adding a more or less complex application architecture, and ending up with abstract figures that are impossible to evaluate. It's just not right. So let's change the game! 💡 With this blog post, let us take you to the world of server energy estimation and discover why understanding consumption is key to sustainable and efficient server management. 📖Read more here: https://lnkd.in/dhH26GpU Erratum : on the document below, you should read "power" instead of "energy" (Watt). #ServerEnergy #Sustainability #TechInsights #BoaviztaBlog
