The Promise Technology ServicePlus-NBD Service Plan for Vess 2000 Series RAID Head with Drives provides an onsite hardware parts replacement service for another three years. It is an upgrade to the original 3-year limited advance replacement warranty. This service is available 24-hours a day, seven days a week for the entire warranty period. The Promise ServicePlus plan is available for both fully configured systems sold through Apple authorized channels as well as Windows and Linux qualified systems sold through PROMISE authorized channels.

The Promise ServicePlus plan offers rapid dispatch and installation of critical replacement components. Storage administrators can rest easy knowing they are backed by an onsite component replacement service. In conjunction with Promise's standard Limited Warranty on the hardware and 24x7 Technical Support help line, this plan assures you the best available support to minimize downtime. Average response time can be as fast as four hours in most major metropolitan areas after failure verification. If you are outside the 4-hour support regions, you will receive Next Business Day (NBD) onsite support. This plan provides support for a system within the United States and Canada.
