First, verify that the NVMe drives in the affected bays are properly seated and connected. Restarting the XClarity Controller (XCC) may also help restore the drive inventory. Additionally, ensure that your server's firmware is up to date and check the VMD settings in the BIOS/UEFI for correct configuration. [community thread]
First, ensure the OCP card is properly seated and check for any visible damage. If the card is still unrecognized, test it in a different compatible server to determine if the issue lies with the OCP itself. [community thread]
The ThinkSystem SR655 v3 750W power supplies are designed to automatically sense dual voltages, supporting both 110V AC (100-127V 50/60 Hz) and 220V AC (200-240V 50/60 Hz). Therefore, they can operate with 208V AC at 60 Hz. [community thread]
Direct CPU PCIe connections typically provide lower latency and more stable bandwidth compared to retimer connections. While retimers can support additional drives, they may introduce slight latency; however, for most applications, the performance difference is negligible. [community thread]
While you may be able to install these drives, their compatibility is not guaranteed, and firmware updates cannot be performed through XCC. Additionally, if any issues arise, warranty coverage may not apply. [community thread]
