Webrequest to a different logical EEPROM memory page is requested, or when the user manually commits the write cache. Without the write cache, each write request to an EEPROM memory page would require a full page write, reducing the system performance and significantly reducing the lifespan of the non-volatile memory. 3.2. Memory Layout WebThe first requirement is trivial to control since the size of the mapping relates to the size of the persistent memory pool file(s). Both EXT4 and XFS each have support for requesting specific filesystem block allocation alignment and size. This feature was introduced in support of RAID, but can be used equally well for DAX filesystems. seattle trail races
