Thats not a really surprising result. Virtio has a LOT of overhead and does a lot of calls that cross the kernel/userspace boundary (read: slow). Even though recent optimizations have made it fairly stable and reasonably capable of sustaining 1+ gbps speeds it still really breaks down on...
Yes. Its a bit of a PITA. It works really well using SR-IOV. Ultimately I like this method much better than a simple PCIe passthrough of the device because you can share the iGPU with up to 7 VMs simultaneously AND you don't lose video for the host itself. But for now it is not mainlined...
It would take some detailed benchmarks to confirm, but you SHOULD see slightly higher overall performance. Each core should be able to sustain higher clocks for longer before thermal controls cause them to back off.
Of course, this is all based on the engineer's most terrifying word: SHOULD... :)
You are likely seeing single-threaded results. With iperf3 set up multiple parallel transfers and look at the totals. You should see something close to 10gbe (9.9+). Not much you can do about file transfers as SMB implementation in Windows just sucks.
There is long history of Intel understating RAM capabilities, all the way back to Pentium days. There were no 48gb sodimms available to test with when 12th gen laptop chips were released so ARK pages only listed what could be tested when they were published…and then they are never updated...
I'd suggest you consider Thunderbolt options. For spinning disks they will be guarenteed full speed. For u.2/m.2 options they will likely be fast enough. You'll spend less money, have fewer/thinner cables to deal with, and you won't have to deal with heat issues inside the chassis (the 9500...
Also just noticed OWC has an NVMe enclosure that can handle either 2x U.2 or 8x m.2 over thunderbolt 3. Not sure how they are mux'ing the 8x m.2 (probably x2 or even x1 per drive). But it could make for a pretty interesting all flash NAS with the MS-01.
OWC mercury
I tested the Thunderbolt using an external OWC Thunderbolt 10gbe box and with an OWC Thunderbolt 3 Pro dock (which also has 10gbe embedded). Both worked perfectly, iperft hits 10g speeds no worries.
I know this isn't the same as testing with a Thunderbolt JBOD but thunderbolt is pretty solid -...
I've got a Sabrent Rocket 4 4tb in the pcie 3.0x2 m.2 slot. Its a double-sided device and works fine. Its not really under much stress so temps are not an issue. Not sure what it would do under load. I did not install any heatsink. It sits right right under the SSD fan but doesn't really...
My use case is a windows VM doing video processing (NVR) so I can’t offer much insight into graphics performance on a Linux vm.
Setup is via dims using this guide. Yes, it’s jumping through a few hoops. But they are simple and Derek’s guide makes it simple.
I’ve only had it in hand for a day and it’s not doing real work yet, but I am really loving this system! Just doing stress tests and a few test OS loads but it really runs nice. Reasonably. Quiet even under heavy loads. Cooling design is rock solid, holds clock even under heavy load. m.2...
You probably have to snap.off the 110mm mount points to get it in the case.
I dont think it would fit. The pcie socket is very cloae to the main pcb.
Even if it fit i think it would cook the SSDs on the bottom. There isn't much airflow on that part of the chassis and even the ones on the top...
