intel Optane intel Optane DataCenter Persistent Memory Module，DCPMM

Is a RAM or SSD？

It maybe a SSD.Just on the DIMM socket.

You can use it with just on CascadeLake CPU.(2nd Generation Intel Xeon Scalable Processor - LGA3647)

intel say it can help enterprise to save lots of money. But I also think it is many expensive.

（Just expensive in China，256GB  30000CNY，Maybe in other countries it is so cheap）

I have one Engineering Sample（ES） and one Pass Sample（QS） DCPMM

【Blue PCB is Engineering Sample（ES） / Green PCB is Pass Sample（QS）】

A：

B：

Pass Sample（QS）relative to Engineering Sample（ES）is doing more modify.

Flash particles，Location of parts，capacitance and powered by.

In China this is them's price：

Engineering Sample（ES）   1250CNY = 178USD

Pass Sample（QS）             2200CNY = 315USD

Formal edition                       4699CNY = 671USD

Most people will to chooes QS. Because,it is so cheap and same of Formal edition.

（If like cpu we need look stepping to chooes，low stepping maybe also have some bug）

 

Engineering Sample's need two same ES DCPMM can use it,one is not，ES is not have AD(AppDirect) module.

Pass Sample（QS） is same of Formal edition'DCPMM just have one, you also can use it.

If you are windows system, you need to use ipmctl.

If you want to use MM(Memory Mode) module, you need DDR4 Ram to mix use with DCPMM.

Best degree of mixing is 1/4. Like 32GB DDR4 with 128GB DCPMM.

Two 256GB DCPMM use on AD and use RAID0, it will have so~fast reading speed with 101GB/s.

This is DCPMM's flash particles，but I don't know what meaning about it.

QS is  29P16B1DLDNF2-183417-QX7E1

ES is  29P16B1BLDNF2-171012-NFDD

But DCPMM is release on 2019 ，the same time with 2nd Generation Intel Xeon Scalable Processor.

Neither and both. It sits in a tier between ram and flash SSDs.

Intel is selling it as a cheaper alternative to ram, particularly for higher capacities. How does it compare in that way?

 

It will suit some workloads better than others. Not having to "reload" things into ram on restart for example.

They were working on it before release. Those are pre-release samples.

But ES's DCPMM is so slowly about DDR4-RAM
