Diverse power entries refer to providing multiple, independent electrical power sources to a data center. Rather than relying solely on a single power feed, this setup involves multiple entry points from distinct utility sources or grids. This redundancy acts as a shield, shielding the data center from unforeseen power failures, outages, or fluctuations. Mitigating Risks: … Read more
Power over Ethernet (PoE) technology allows electrical power and data to be transmitted together over standard Ethernet cables, typically Cat5e, Cat6, or Cat7 cables. It eliminates the need for separate power cables, simplifying installations and providing power to devices like IP cameras, VoIP phones, wireless access points, and other networked devices. 1. Ethernet Cable Transmission: … Read more
Christmas is rapidly approaching. I hope this edition finds you well and as stress-free as you can be for the holidays. In the networking world, the time between Thanksgiving and New Year’s is fairly laid back. Data Centers scale down their work as do service provider networks. Folks are taking time off, and their customers … Read more
Over the next several weeks, I will convert some categories to Tags. I am doing this to streamline finding relevant content on this blog as well as my ability to quickly post items.
‘Tis the season to be jolly, and amidst the joyous festivities, let’s take a moment to celebrate the unsung heroes of our connected world—the ISPs (Internet Service Providers) who work tirelessly behind the scenes to keep our digital sleighs flying high. So, gather ’round, for this festive blog is dedicated to a Merry ISP Network … Read more
In simple terms, a subnet mask is a 32-bit numeric address that delineates the network portion of an IP address from the host portion. It works in conjunction with IP addresses to divide a large network into smaller, more manageable segments called subnets. In this article, I will mainly focus on IPV4 subnets. A subnet … Read more
Amidst this complex network ecosystem, BGP Looking Glass servers stand as invaluable tools offering transparency and insight into the world of routing. They are used to troubleshoot and visualize how networks view routes. BGP Looking Glass servers are essentially web-based tools or servers provided by network service providers, internet exchanges, or organizations. They enable users, … Read more
My test switch form Alta labs has arrived. More posts coming soon. I am so excited I had to snap quick photo of it
Managing the heat generated by servers and equipment is crucial for ensuring these centers operate at peak efficiency while maintaining reliability. Below are four methods used to cool. For many of you, this is old news. 1. Traditional Air Cooling The most common method involves using air conditioning units to maintain a consistent temperature. Hot … Read more
