Hello,
As mentioned by Torsten the physical drive carriers are not the same and incompatable.
More importantly, the P2000 controller will lay down the metadata structure in a specific way. The DL380 uses a Smart Array to lay down data structures for a LUN to be presented to the server. If your intenetion is to insert the P2000 HDDs into the server and read the data from them you will not be successful. Be sure to backup any data that is currently on the P2000 before moving the drives to any other system.
One other data point to take into consideration. Any drives coming from the P2000 are likely several years old. Using old drives in a new solution opens up the door for drive failures causing a loss of access to a new solution. Your best option would be to source new drives in order to better protect your data.
Cheers,
Shawn
