This PowerEdge R660 configuration uses all 16 storage slots for E3.S NVMe drives. This configuration needs two PERC12 H965i. The left eight drives are downstream from one H965i, which connects to CPU2. The right eight drives are downstream from the other H965i, which connects to CPU1. This configuration supports the maximum E3.S NVMe capacity. This configuration supports E3.S and PCIe Gen5, which enables the highest NVMe performance available.
