Gen 5 Fibre Channel is the latest evolution in Storage Area Networks (SANs). Based on technology developed by the T11 technical committee that defines Fibre Channel interfaces, Gen 5 Fibre Channel doubles the data throughput of 8 Gbps links, from 800 Megabytes per second (MB/sec) to 1600 MB/sec with Gen 5 Fibre Channel.
The benefits of faster networking technology are easy to understand. Data transfers are faster, fewer links are needed to accomplish the same task, fewer devices need to be managed, and less power is consumed when Gen 5 Fibre Channel is used. Several server and storage technology advances are pushing up demand for greater SAN bandwidth, including application and storage capacity growth, high-density server virtualization, new Gen 5 Fibre Channel storage arrays, and Solid State Drive (SSD) or Flash-based storage. Gen 5 Fibre Channel enables enterprise data centers to unleash the full potential of these and other advanced technologies.
The advantages of Gen 5 Fibre Channel, however, extend beyond performance and higher throughput. Gen 5 Fibre Channel delivers several important capabilities that take SAN reliability, availability, and management simplicity to the next level, driving down operational costs. It is these advantages that are driving the
IBM and Brocade have a long history of collaboration, and I am sure that there are people out there that will remember the IBM 2109-S08, which was an 8-port, 2 Gb/sec, and possibly some that can go back even further than that !
Anyway, let's move on from memory lane and how much better it was in the old days!
We have just published an IBM Redbook draft on the Gen 5 and IBM Network Advisor:
