The server also can operate in independent channel mode or combined channel mode (lockstep).
When running in lockstep mode, user gains reliability in one of two ways:
If running with UDIMMs (built with x8 DRAM devices), the system can survive a complete DRAM
failure (SDDC). In independent channel mode, this failure would be an uncorrectable error.
If running with RDIMM (built with x4 DRAM devices), the system can survive the complete failure
of two DRAM devices (DDDC). Running in independent mode, the server can only survive the

complete failure of a Single DRAM Device (SDDC).
