Can't wait to see Optane as RAM tests using lmdb.
- hyc_symas 8y agoI hope to have the next writeup done in a couple days...
- tanelpoder 8y agoI wasn't aware that the Xeon Gold CPUs (61xx instead of Xeon E5 or E7 x6xx models) also support the Intel Memory Drive Technology. If yes, then great! Or are you going to use a different server for the IMDT test?
- wtallis 8y agoI don't think MDT has any particular hardware requirements beyond the usual modern virtualization feature set. It seems to be supported on all LGA2011[x] Xeons going back to Ivy Bridge, and the current Xeon Scalable product line (Platinum, Gold, Silver, Bronze) on LGA3467. I wouldn't be surprised if it could be made to work on the desktop platforms, too, but it probably wouldn't be worth the trouble.
- hyc_symas 8y agoThe same server is used for the IMDT tests. From what I saw, IMDT is basically a thin hypervisor that maps the SSD into the address space and then handles the page faults before the main OS ever sees them. I don't think this requires anything that any arbitrary CPU/MMU couldn't handle.

- dis-sys 8y agothanks for the update. its boost to the read throughput looks amazing.
