Intel recently submitted new patch code to the Linux kernel to continuously optimize the performance of Austen’s sustainable memory, improving memory access performance on dual-way systems by 116 percent. This patch is primarily intended for systems with proud sustainable memory, which is different from memory in storage hierarchies and from flash memory, but somewhere in between.
The purpose of this patch is to properly transfer hot pages that were originally stored on Aoten’s sustainable memory to DRAM memory, which in turn allows cold pages to be stored in Austen Sustainable Memory.
Since the performance of DRAM memory is still significantly higher than that of Audon’s sustainable memory, it is also normal for performance to improve significantly. In the test, the 80:20 ratio read: write under, the pmbench benchmark memory access performance benchmark performance performance increased by 116%.
Aoten DC Sustainable Memory uses the standard DDR4 form factor and interface protocol, is fully compatible with existing DDR4 slots and can be used directly, but needs to be co-located with DDR4 memory on the same channel (i.e. one Austen memory per channel with a DDR4 memory) and needs to be plugged into a slot closer to the CPU per channel.
According to Intel’s memory storage hierarchy, AftonDC memory is immediately after the system DRAM, mainly used to increase system memory capacity, Afting DC SSD SSD SSD is placed between Afton DC memory, traditional flash SSDs, improve storage performance.
The aoten memory card capacity currently offers 128GB, 256GB, 512GB, maximum power consumption of 18W, the highest frequency is equivalent to DDR4-2666, the reading bandwidth of up to 6.8GB/s, the write bandwidth of up to 2.3GB/s.
