3 PCIe-Mounted SSDs on Dell R620 Cause PSUs to Blink Orange
Hi everyone,
Running into an issue with a small project on our Dell R620 servers. We're able to utilize 2 PCIe-mounted NVME SSDs that are slotted into the far left and far right PCIe slots. This setup runs fine. However, when we try to put a drive into the middle PCIe slot, it causes the power supplies to blink orange. Removing the drive from the middle slot causes the power supplies to no longer blink orange. I've been able to re-create this issue on two R620 servers with different hardware.
The SSDs we are using are WD Red SN700s attached to an M.2 NVME to PCIe x4 adapter.
We are using 2x 750W power supplies.
Any suggestions on this?
Thank you!@

I've seen this many times before when End-Users upgrades or add in too many components for the wattage they have available. This is being caused by the power consumptions of the PSUs reaching their thresholds.
The simple way to fix it is upgrading your PSUs, or sticking to using just the two PCIe NVME cards.

ZachVTS,
The first thing I am seeing is that the SSDs in question, the WD Red SN700, are not listed as supported for the server, so that may be the cause of the issue.
Let me know if this helps.

@DELL-Chris H Installation of just 2 of these drives works fine in our setup. 3 is where the issue occurs. We also recently tested with 2 SN700s and an Nvidia Quadro with the same result - PSUs blinking amber. So, we might be hitting wattage limits.
