When choosing enterprise NVMe storage for servers and data centers, two form factors are commonly discussed today: U.2 and E3.S. Although both are designed for high-performance and high-reliability workloads, they differ significantly in physical design, scalability, cooling, and long-term viability.
This article explains the key differences in a practical and easy-to-understand way.
When designing a modern data center network, a very common architecture today is L3 underlay + VXLAN overlay + EVPN.
Sooner or later, however, the following question comes up:
Do I really need EVPN L3 routing (L3 VNI) if I only need Layer 2 connectivity over a Layer 3 network?
The short answer is: no, you don’t.
The longer and more important answer is when it makes sense and when it doesn’t.
That’s exactly what this article explains.
If you have ever built or operated a real network, you already know the problem: networking is often the last part of the infrastructure that still relies on manual work, device-by-device configuration, and vendor-specific CLI syntax. While compute and storage moved towards automation and declarative management years ago, networking often lags behind.
Here are two introductions videos ...
In this post, I want to briefly introduce Netris and explain why it is interesting from the perspective of modern, automation-driven environments.
The term “FRR router” appears frequently in enterprise, datacenter, and ISP networking discussions. Despite how it sounds, it is not a product name and not a hardware device.
Free Range Routing (FRR) is an open-source routing software suite. The name Free Range reflects its original goal: routing software that is free, open, flexible, and not tied to proprietary hardware.
FRR provides implementations of major dynamic routing protocols and runs on general-purpose operating systems such as Linux and FreeBSD.
When you hear terms like SFP, DAC, CWDM, or 100G, it can feel confusing at first. These technologies are common in data centers, ISPs, and modern enterprise networks.
This guide breaks them down in a simple, practical way that anyone can understand.
SFP, SFP+, SFP28, QSFP - What Are These?
These are small, pluggable modules that go into switches, routers, servers, and transmission devices. They allow network equipment to connect using fiber or copper.

Coriolis is Cloud Migration as a Service.
Migrating existing workloads between clouds is a necessity for a large number of use cases, especially for user moving from traditional virtualization technologies like VMware vSphere or Microsoft System Center VMM to Azure / AzureStack, OpenStack, Amazon AWS or Google Cloud. Furthermore, cloud to cloud migrations, like AWS to Azure are also a common requirement.
