The company announced its latest versions of the AlphaServer family, including the AlphaServer DS20L server and the AlphaServer SC20 supercomputer.
Two Evo desktops for business customers were also released, the Evo D510 Desktop, and the Evo D310 Desktop, which feature Intel's new 845G chipset.
Additionally, HP released its two latest versions of the Evo Notebook N800, one for corporate users and one for small businesses and consumers.
The AlphaServer family has now been updated under its third owner. Compaq acquired the reduced instruction set computer (RISC) technology that powers the DS20L and SC20 when it bought Digital Equipment in 1998.
RISC microprocessors are designed for intensive computing applications, such as detailed graphics or research and development. Each processor is limited in the number of instructions it is required to undertake, allowing it to perform those limited tasks much faster than ordinary microprocessors.
The DS20L and SC20 target users in telecommunication, and users engaged in "high-performance technical computing (HPTC)", said Rich Marcello, vice-president and general manager of the Alpha systems division. HPTC users include life sciences companies, which would use the machines for intense computational processes, he said.
Each DS20L server comes with two 64-bit Alpha processors, and features up to 2Gbytes of memory. A system with 512Mbytes of memory and 18.2Gbytes of disc storage has an estimated price of $18,000 (£12,300).
The SC20 is made by combining DS20L units, which can scale to a maximum of 128 DS20L servers, or a total of 256 Alpha processors. It will come with a base system of eight Alpha processors and 4Gbytes of memory, and is estimated to cost £200,000 when it ships in August, HP said.
Both systems run HP's Tru64 Unix, and the DS20L is also available with the Linux operating system. The new systems will not run on OpenVMS, as they are aimed at the telecom and HPTC markets. HP does not have enough VMS customers for a VMS version to make sense, Marcello said.
Compaq announced in June 2001 that it would be transferring its 64-bit servers to Intel's Itanium microprocessors by 2004, before HP signalled its intention to buy Compaq.
HP will honour the Compaq roadmap for the Alpha microprocessor, and Alpha users can expect improvements and support for the rest of the decade, he said.
