Since I work in the SMB/Commercial space as a TC, I routintely am exposed to mixed fabric environments. With the advent of iSCSI, we’ve seen a proportional shift towards iSCSI as a reduced-cost block storage fabric. Legacy (2Gb/s) fibre still has presence in specific markets but the uptake of 4Gb/s fibre has been slowing down. With FCoE being announced as the next logical evolution of converged fabrics and 8Gb/s FC and 10G iSCSI working their way to availability, does FCoE make sense for SMB/Commercial markets?

In Part 3a, we discussed the possibility of a purpose-driven Compute Node based on the Torrenza initiative for the Future Storage system. This expansion node made use of Hypertransport as a “glue” between the base storage compute node and the expansion node (of computation or I/O flavours) that could be added. The advantages of that topology were simple: hot add support for additional processing power, additional I/O bandwidth within the system, and additional computing power for the array OS (which we’ll cover in a later article). In this overview, we’ll take a look at another variation on an expansion node: an I/O expansion node that will add additional front-end ports and/or functionality to the base system. We will be referencing the diagram below. (Apologies in advance for the image shearing off in the lower right hand corner).
