Hello.   NBD ProSupport covers both supported hardware and software on your server for the duration of the contract. Parts Only means that replacement parts are shipped to your business location without our onsite technician to assist. In this case, you will have to rely on your local technician to install, test and certify that the part is fine and working correctly. There is also an option of the parts being shipped with our onsite technician.   Again NBD ProSupport covers any supported faulty hardware from system board , hard drives, memory, CPUs to cables etc. It also covers operating system and other software like OpenMange Server Administrator (OMSA). Next business day means that when replacement parts are processed for shipping before end of business day, they should be available at your business location the following day before closure of business. I hope this answers your questions.
