Thank you for posting in the Intel® communities.
Regarding to your inquiry, I have to tell you that the Intel® Optane™ SSD 900P Series is not a Data Center family. They have been designed for Consumer usage rather than Data Center usage, therefore the use and performance on server environments is not supported nor validated.
Having said this, we don’t recommend you to use this drive in server environments. Instead, I recommend you to check the Data Center families that will work better in your environment: https://ark.intel.com/#@DataCenterSSDs
Additionally, from the Intel® Server Board S5520UR side, based on this information: https://ark.intel.com/products/36456/Intel-Server-Board-S5520UR, this board has been discontinued since 2013 so it’s probably that it won’t work with newer drives.
I hope this information answers your concern. If there is anything else I can help you with, feel free to ask.
Have a nice day.
