Hello maxima120 I don't see any way that the card will work in an R320. You will run into two issues, power and space. The #1 problem is that this is a 300W card that requires two additional power cables to be attached(The power supply does not have these cables). Also, the system only comes with 350 watt power supplies. There is no way they can power this card. In a maximum load condition with two power supplies the redundant power supply can be oversubscribed by 15% for a total maximum output of 402 watts, so even if you were able to somehow attach the additional power cables that don't exist the power supply could not power it. The second issue is the card length. It is a full length card and the x16 slot in the R320 is full height half length. I don't think the card will physically fit in the server. Thanks
Is there a limitation with what host CPU Intel Phi are compatible? Will 3100 work with E5-1420 ?  How to calculate PSU wattage for a system with a Phi?   Will 3100 fit into 1U server (such as Dell R320) ?
Can I fit Intel Phi into R320?
