This architecture is enhancement over Chassis Generation 3 with few differences mentioned below 1)DDR Layout ============ Entire DDR region splits into three regions. - Region 1 is at address 0x8000_0000 to 0xffff_ffff. - Region 2 is at address 0x20_8000_0000 to 0x3f_ffff_ffff, - Region 3 is at address 0x60_0000_0000 to the top of memory, for example 140GB, 0x63_7fff_ffff. All DDR memory is marked as cache-enabled. 2)IFC is removed 3)Number of I2C controllers increased to 8
