High level of availability and data security
When memory data is accessed, 1-bit errors in the main memory are identified
and automatically corrected with the ECC (Error Correcting Code) method.
The memory modules used support SDDC technology (Chipkill™), which
further increases the effectiveness of memory error monitoring and correction.
Support is likewise provided for hot-spare memory technology, in which a
memory module is used like a replacement module. If a memory module fails,
the module with the defective memory is automatically deactivated and the
replacement module is activated (provided it has been configured for
appropriately in the BIOS). The deactivated memory module is no longer used
This option can only be ordered from the manufacturer and is
indicated by the logo on the identification rating plate.
