In recent years, we have seen an increase in the performance of data storage technologies, which eventually reached the physical limits due to outdated data exchange protocols in data centers. Despite the use of 100GbE and new networking technologies such as InfiniBand, these legacy protocols continue to slow down the performance of flash drives because they are isolated within devices. In this article, we will talk about the non-Volatile Memory Express (NVMe) specification. Next, we'll focus on NVMe over Fabrics (NVMe-oF) and NVMe over RDMA over Converged Ethernet (NVMe over RoCE), new Protocol specifications designed to address problem points in modern storage networks.

Operational technologies, or OT, are a critical segment of the network used by businesses that produce goods or engage in physical processes. Industries such as manufacturing, chemical, oil and gas, mining, transport and logistics use specialized technologies to manage facilities: Assembly and production sites and power systems. The control, monitoring, and management of these systems have been gradually automated over the past few decades, and the specialized systems that perform these tasks are called industrial control systems (ICS), dispatch control, and data acquisition (SCADA), or simply OT.

As the cloud business grows, so does its impact on the environment. Many companies aim for zero net emissions, but Microsoft goes even further: the company doesn't just reduce its emissions to zero, but seeks to remove the carbon it has been emitting into the atmosphere since 1975 in order to truly move to negative carbon emissions.

We take a powerful server and immerse it in a tank of liquid, then apply voltage and hope that no sparks fly. But maybe we should be afraid of something else: continue to build data centers with a service life of more than 10 years, the cooling of which depends solely on air flows? How sustainable is an industry that spends more on providing electricity to rotating fans than it does on powering processors?
