Why each option

To ensure server functionality despite a memory stick failure, solutions like Memory RAID or a hot spare module are employed.

AChipkill

Chipkill is an advanced error correction technology that can correct multi-bit errors within a memory chip but typically cannot recover from a full stick (module) failure.

BMemory RAIDCorrect

Memory RAID (e.g., memory mirroring) provides redundancy, allowing the system to continue operating using a mirrored memory module if one fails, thus maintaining server functionality. This configuration ensures data is duplicated across memory modules.

CRegistered memory

Registered memory (RDIMM) includes a buffer for electrical signals to improve stability in high-density configurations, but it does not provide fault tolerance for a failed module.

DECC

ECC (Error-Correcting Code) memory detects and corrects single-bit errors and detects some multi-bit errors within a memory module, but it does not typically prevent a system crash if an entire stick fails.

EHot spareCorrect

A hot spare memory module is a pre-installed, inactive memory stick that automatically takes over if an active module fails, ensuring continuous operation without manual intervention during a component failure.
