Supermicro SuperServer with Intel Optane DC Persistent Memory First Look Review Discussion

Recommended Posts

In addition for support for the latest Intel data center technologies, the system provides storage via ten hot swappable 2.5" NVMe bays in the front. Internally Supermicro provides support for two M.2 slots, one SATA and one NVMe, though additional M.2 slots can be added as an option. The board supports 24 DIMM slots, which can be used in the traditional way with DRAM, or with persistent memory as is the configuration in this review. Looking at connectivity, the system has two 10GBase-T LAN ports on board. Expansion for additional connectivity is available via two PCI-E 3.0 x16 (FH, 10.5"L) card slots.

awesome! many thanks for this very first review!
Of course we are hoping for a direct comparison of Optane DC Persistent Memory vs Optane NVME PCIe 3.0 x4 like P4800x or even 905P :-)

I don't know why they didn't do it, but you can compare with the results they got with their P4800X review. Lot more bandwidth with lot lower latency basically.

thanks for pointing to this!

for others: this review can be find here:

Of course it would be even more informative to have everything in the same graphs...

A comparison with a "normal" SSD shows a little distorted picture...

  • different technology
  • completely different price per GB

of course a near perfect comparison would be new DC Persistent Memory Optane in 6 RAM channels vs 6 PCIe NVME Optane in RAID 0...

We don't have a big pool of Intel NVMe drives unfortunately. We have more coming on this though, early days still.

RAID will increase sequential bandwidth, but the enormous latency advantage of Optane PMM will increase because RAID on Optane adds significant latency(even with VROC).

Bandwidth isn't the big point with Optane. Even with the P4800X, you could get NAND SSDs that do better in sequential throughput. It's the consistency in performance due to write-in-place media and super low latency that makes it what it is.

sure, you are right!
 

The idea is to bench

  • same number of devices,
  • with same number of connections,
  • with nearly the same cost,
  • with same internal tech (optane)
  • only differ the type of connection (RAM slot vs PCIe)
