Preparing for the Future
LSI is employing their version of Intel's Tick "" Tock strategy. The first move is the leap to PCI Express 3.0 and then later the move to SAS 12Gbps.
In the provided graph we see the previous generation performance under PCIe 2.0 (far left, blue). The next step shows the new generation 6Gbps performance with PCIe 3.0 (middle, red). Then LSI gives us a glimpse of the future with PCIe 3.0 and 12Gbps.
In the chart you will notice that LSI also calculated overhead associated with both PCIe and SAS.
LSI provided us with some general performance data for their new PCIe 3.0 product line up.
