The e3000 is a midrange system that includes its own database, and has been widely praised by users for its reliability. HP doesn't give out the number of users, but an OpenMPE official had earlier estimated that there are about 2,000 users with e3000 systems in operation.

HP has set up migration programs for users to move from OpenMPE, but some users planned to 'homestead' on the system and run it past the initial end-of-life date. OpenMPE had set a budget of about US$1.5 million in user fees to provide operating system support.
