HP i2000 Internals
4.32 HP i2000
4.32.1 Overview
The HP i2000 was HP’s first Itanium workstation with a first generation Itanium processor (Merced)
and more a proof-of-concept to deliver first Itanium hardware, based on an early Intel reference design
(which was also rebranded and sold by other vendors). The system had certain limitations (some due
to chipset/OS bugs), supported only first generation Itanium CPUs and was rather slow.
Time of introduction: 2001, with price at the time of $7,000 to $15,000.
