Memory access is a critical factor for performance and consolidation. Speed of memory is measured in mega transfers per second (MT/s). MT/s is a unit that indicates the data transfer rate per second. For example, a DDR5 speed starts at 3,200 MT/s and higher transfer rates can be achieved with 6,400 MT/s memory.
Both RDIMM and LRDIMM memory types are good choices for PowerEdge servers. The main factor that should be considered when choosing between the two is capacity.
