As less switches are used in EoR design, more cables are deployed between racks triggering higher possibility of cable mess. Because when two servers in the same rack and VLAN (virtual local area network) need to talk to each other, the traffic will go to the aggregation switch first before comes back. In addition, ToR approach takes up more rack space for the installation of switches.Īs for EoR, its Layer 2 traffic efficiency is lower than the ToR. The management of switches may be a little tricky. For ToR, although the cables are reduced, the number of racks is still increased. In reverse, there are also some limitations for each architecture. With less devices in data center, there will be less requirements for the cooling system which also reduces the using of electricity power. Thus, less rack space is required in the architecture.
In the EoR, device count is decreased because not every rack should equip the switches. Technicians can also add or remove cables in a simpler way. Cable management is also easier with less cables involved. We provide the essential expertise and vital solutions your business needs to thrive.As for ToR, the cost of cables are reduced since all server connections are terminated to its own rack and less cables are installed between the server and network racks. FS is committed to helping customers expand capacity, enhance efficiency and speed deployment. The whole cabling design makes full use of MTP high-density cables and FS cost-effective FHD system to ensure the right polarity and provides easy cable management. The connection between the FHD fiber enclosures on the two racks is achieved by male 144 fibers MTP-12, Type B trunk cables. The same connection is also used in ToR cabling at the other side. How to ensure the right polarity, connector type (female/male) and easy cable management of the whole 40G transmission? SolutionĤ0G switches and 1U rack mount FHD fiber enclosure (accommodating 4x FHD adapter panels ) are connected by female MTP-12, Type B trunk cables. Our regular customer Code42 Software Inc, a Data Loss Protection Solution Provider, asked us to design a scalable and polarity-clear MTP cabling solution for their 40G connection between the EoR and ToR. In today’s high-density networking environments, having a flexible, standard-based structured cabling system is critical for network upgrade or expansion.
