The arrival of 10G Ethernet at price points that would trigger the traditional adoption and ramp-up is finally here. Standards for copper twisted pair physical layers are ratified. First real implementations of 10G twisted pair PHYs have been tested. And production versions on technologies which don’t melt the PCB appear to be around the corner. As shown in the past several technology upgrades of Ethernet, adoption should be rapid once the remaining hurdles are cleared.
Network controllers seem to have just reached the point where they can deal effectively with 1G traffic, balancing the performance of NICs, processors, memories, and storage interfaces. 10G will demand more than just incremental changes to the architectures of network engines as well and storage processing systems. This poses significant challenges to vendors vying to provide the next generation of storage controllers to exploit the benefit of 10G.
This white paper explains the upcoming changes and shows how the iSCSI RAID Storage Processor meets the goals of providing a robust 10G end-to-end storage solution.
