Having insight and awareness into how your environment along with applications is important to know to focus resources. Also keep in mind that a bit of flash SSD or DRAM cache in the applicable place can go along way while a lot of cache will also cost you cash. Even if you cant eliminate I/Os, look for ways to decrease their impact on your applications and systems.

Green IT is about enabling efficient, effective and productive information services delivery. There is a growing green gap between green hype messaging or green washing and IT pain point issues including limits on availability or rising costs of power, cooling, floor-space as well as e-waste and environmental health and safety (PCFE). To close the gap will involve addressing green messaging and rhetoric closer to where IT organizations pain points are and where budget dollars exists that can address PCFE and other green related issues as a by-product.

The NUC has been around new for a few years and continues to evolve and recently I bought my first one (e.g. a 4th generation model) to join some other servers that I have. My reason for getting a NUC is to use it as a simple low-power platform to run different software on including bare-metal OS, hypervisors, cloud, virtual and software defined server storage and networking applications on that might otherwise be on an old laptop or mini-tower.

Do you need a new server, second or third server, or expand a cluster, create a lab or similar and want the ability to tailor your system without shopping or a motherboard, enclosure, power supply and so forth?
