10G Stacking Over Cat6a or DAC

10G Stacking Over Cat6a or DAC

We have got benefits from the stacking of 10G SFP+ switches for the past decades, and the 10G SFP+ direct attach cable (DAC) makes the stacking low-cost. But when 10GBASE-T becomes a new port choice on 10G switches, stacking on 10G switches has to meet the issue about whether to choose Cat6a or SFP+ DAC. At first people think that Ethernet cable is cheaper and easier to deploy than SFP+ DAC, but later they realized the issue is not only…

10G SFP+ Copper Transceiver Solution

10G SFP+ Copper Transceiver Solution

It’s said that switch manufacturers are entering into the new fiber transceiver era. Only SFP+ or SFP cages are implemented for future flexibility. And copper ports were only implemented for management purpose so far. However, we cannot deny the fact that there are some applications in the past with 1G where Servers or other components do only have 1G copper ports. So 1G copper SFPs have the right to exist. Now all connections moved from 1G to 10G and the…

Why Leaf-Spine Architecture and How to Design It?

Why Leaf-Spine Architecture and How to Design It?

With the demand for higher bandwidth, faster speeds and optimal applications, equipment architecture trends have changed from traditional 3-tier architecture model to leaf-spine architecture in existing data centers. 3-tier architecture vs. leaf-spine architecture: which is better? What should be considered when deploying one network architecture over the other? 3-Tier Architecture vs. Leaf-Spine Architecture The traditional 3-tier architecture model is designed for use in general networks, usually segmented into pods which constrained the location of devices such as virtual servers. 3-tier…

Proper Cabling Solutions for PoE Network

Proper Cabling Solutions for PoE Network

By running power and data transmission over a single Ethernet cable, PoE (Power over Ethernet) has found success across a variety of applications such as IP surveillance cameras, IP phones and wireless access points. However, without the right cabling and network design in place, PoE can encounter cable heating and connectivity issues that may adversely affect performance. So in this post, some cabling recommendations for PoE will be listed for your reference. Issues Affect PoE Performance Heat generation in cable…
