The M-Series is a 4U~52U system with dual controllers. Each controller has NVDIMMs for extremely low latency write caching and there is a high bandwidth PCIe interconnect between controllers to synchronize the NVDIMMs. The controllers share access to 24 x 3.5” drives (HDD, SSD, RI-SSD) and also can share 4 low latency NVMe drives which can be used for metadata or persistent read cache.
