HP Support Plus service is composed of comprehensive hardware and software services that help increase the availability of your IT infrastructure. HP technical resources work with your IT team to help you resolve hardware and software problems with HP and selected third-party products. If you are a security conscious company, you might consider adding comprehensive defective media retention (DMR) service to your hardware support agreement. HP DMR lets you keep and control your disk and your data. The process closely resembles what happens in a standard service call. If a disk covered by the retention malfunctions, you call Hewlett Packard Enterprise for support. An HP support agent will diagnose your system problem, dispatch personnel and provide a replacement disk/part.
