To keep up with growing enterprise networks, transmission speeds and expansions in data center capacities are constantly changing, from 1G, 10G, 40G to 100G. And obviously, 100G will become the mainstream. It is said that by 2019, 100G Ethernet will make up more than 50 percent of data center fiber optic transmissions. To smoothly migrate […]

Network OS for Open Networking: ONL vs OpenSwitch?
Driven by software defined networks (SDN) and open standards (such as the OpenFlow protocol), open networking is emerging quickly in data center networks. It is based on open standard and bare-metal switch with flexible choice of open software for operating system (OS), SDN, virtualization, and cloud orchestration. This post will discuss two kinds of network […]
What’s iSCSI SAN and How It Works
iSCSI, which is short for Internet Small Computer System Interface, is a SCSI (Small Computer System Interface) transport protocol for mapping of block-oriented storage data over TCP/IP networks. It enables universal access to storage devices and storage area networks (SANs) over standard TCP/IP networks. This post will introduce iSCSI SAN and how it works in […]
The Changing Network Architecture in 25G/100G Data Center
The demand for high-speed data communications is rapidly increasing, changes to transmission speeds and expansions in data center capacities may spur this trend. Therefore, the market is ready to move to 25G and 100G switches, which can be built in new configurations for large cloud service providers and data center owners. This article mainly analyzes the […]
Leaf-Spine Topology and Its Construction Examples
For many years, data centers have been built in three-tier architecture, comprised of the core, aggregation and access layers. But with the data center consolidation, virtualization, hyper-converged systems springing up, the way data flows is shifting from traditional north-south to east-west inside data center. As the volume of east to west traffic increases, network bottlenecks […]
How to Run Cables in Multi-Floor Data Center With Fiber Enclosures?
In the previous post—Modular Patching Solutions for Flexible Cable Management, I have introduced one kind of FHD fiber enclosure with user-friendly slide-out drawer and flexible mounting options. Actually, besides that rack mount fiber enclosure, there is another kind of FHD fiber enclosure useful in cable running and managing: wall mount fiber enclosure. It is very […]
