Fibre Channel-OM3 and OM4 connectivityįibre Channel transport is essentially tip-to-tip optical connectivity. In other words, for the vast majority of data center users, a 100-meter channel distance is more than sufficient to meet their needs. Trends have shown that as Ethernet data rates have increased from 10 to 40 to 100G, and Fibre Channel data rates have increased from 8 to 16 to 32G, the 100-meter channel distance represents approximately 95 percent of deployed OM3 and 90 percent of deployed OM4 channel lengths. Corning has tracked and modeled multimode and singlemode fiber connectivity data center channel lengths for an extended period of time.
A primary objective is to deliver economical solutions that meet distance objectives representative of deployed multimode fiber connectivity channel lengths. Multimode fiber connectivity distancesĮthernet and Fibre Channel transmission standards develop guidance based on specific criteria that includes technical and commercial feasibility. For the vast majority of users, a 100-meter channel distance is more than sufficient. Long-term tracking has shown that the 100-meter channel distance represents nearly 95 percent of deployed OM3 and 90 percent of deployed OM4 channel lengths. The future server trend is for an increased number of processor cores such that Ethernet 50G/100G (NIC) and 64-Gbit Fibre Channel (HBA) interconnects will be required. The increased server processing necessitates higher Ethernet network data rate input/output (I/O) as well as increased Fibre Channel data rates (16 Gbit/sec Fibre Channel/32 Gbit/sec Fibre Channel) into the server host bust adapters (HBA) to access and deliver external data for the server applications. In addition, servers are now using Peripheral Component Interconnect Express-3 (PCIe3 8G/lane) bus speeds, and PCIe4 16G/lane is fast approaching to complement the increased number of processor cores. Each core normally has 2 GHz of processing capability that translates into 8-24 GHz of total capability. Typical enterprise data centers are deploying servers today with integrated multi-core processors that range from 4 to 12 cores. As servers and storage technologies have progressed over time, Fibre Channel data rates have increased in tandem to support.
Fibre Channel-The need for speedįibre Channel’s deterministic data delivery, low latency and proven reliability have made it the leading transport technology for linking servers to external data storage. It was developed and is updated by the Fibre Channel Industry Association. The Fibre Channel Speedmap details the past, present and future of Fibre Channel.
