The VSP E1090 features a new controller board powered by two 16-core Intel Cascade Lake CPUs operating at 2.1 GHz. The two CPUs function as a single 32-core MPU per controller. The upgraded controller board adds 14% more CPU power compared to the VSP E990. The extra processing power enables the VSP E1090 to leverage the NVMe protocol, which has a low-latency command set and multiple queues per device, for unprecedented performance in a midsized package. Because NVMe doesn’t allow for cascading connections, the VSP E1090 supports a maximum of 4 NVMe drive boxes connected to the controllers using PCI Express Gen3. This simple, streamlined configuration allows for low-latency, point-to-point connections between the E1090 controllers and the NVMe SSDs.
