Third Party NVMe Adapter Support and 8 NVMe Drives in a Dell 7820
Вставка
- Опубліковано 4 лис 2021
- In this video we discover that the Dell 7820 can support Third Party PCI-E x16 Quad NVMe Adapters. We also learned that the Dell 7820 can bifurcate atleast 2 x16 lanes allowing for a total of 8 NVMe drives to be used. Which is just absurd!

HI SPX Labs, i am testing now the Asus Hyper X M.2 Card on a Precision 5820. I was trying to use FreeNAS without luck to recognize the drives. I do not have a VROC key on my system, is this a problem? i don´t think so or? I will try with Unraid. My system has a Xeon W-2225 and the four singles drives are recognized by Windows for example when i install Windows as OS. Another question, how do you boot install unraid without a GPU? if the two 16x Slots are occupied by PCIe cards, no real slot is free for a GPU, at least to install Unraid, is it possible to just install the GPU onto another slot? Thanks for the videos!! very helpful.
VROC is only need for RAID setups. I don’t have VROC either. Not sure why windows can see the drives but free Nas cannot.
Unraid does not install like a traditional OS. After you download the installer and put it on a USB, unraid installs itself on boot every time. You can pre input a IP address or let DHCP do it’s thing. Unraid is managed through the WebUI.
what driver do i need to make this work my m.2 nvme drives do not show up
None. You just need to have a bios that can do bifurcation. In the bios there may be an option to split a 16 lane slot into x4x4x4x4
I have gone the all SSD router (well sorta)
My Unraid server is as follows:
2920x, 64gb ram, 32gb USB (Unraid)
SAS 12G Controller
Enclosure 1 (HP 20000) 4ea 7.68tb SAS 12G SSD drives, 1ea 6.4tb SAS 12g SSD drive (These are setup as ZFS raidz)
Also part of enclosure 1, 5ea 8tb EVO SSD Drives (Setup as cache and all data stored on them)
Enclosure 2 (Netapp SD4246) 4ea 10tb Enterprise SAS 12G drives (Main Array for backup purposes only)
also part of enclosure 1, 6ea 6tb Enterprise SAS 12g drives (testing purpose drives)
10tb backup drive kept in safe
Remote QNAP going to be kept at offsite location (8x2tb EVO SSD Drives)
So far the SAS SSD drives during transfers are hitting between 500-750mb/s, when I run the FIO command it says 3200-4000mb/s
The cache array is pretty solid at 600mb/s.
I was going to go all NVME, but I came across some awesome deals on the large capacity drives.
Please help me, I have 2x Xeon gold 6148, 80 threads, but I want to reduce it to 64 in Bios of Dell T7820. I really don't know how and where. Thank you
Um. Why not just remove the second cpu?
@@SPXLabs I need 64 threads. I can't find the CPU configuration in Bios. ChatGPT says I can do that in Hyper-thread control. But I can't get to that section.
Windows or Linux?
Win 11 pro
Okay well I’m not 100% but System Config > boot > advanced options > then select number of processors. According to Google anyway.
Neat!
Why stop at 8?! Build a cluster 🤓😎
