HP announced the changes Monday, but Chief Executive Carly Fiorina and other executives will detail them during a Webcast on Tuesday.
Itanium arrived slower than co-inventors HP and Intel wanted, but the computer and printer maker is asserting its new server lines are catching on. Itanium-related sales topped $1 billion in 2004, and HP's Itanium server shipments will match those based on its PA-RISC processor by the end of the year, HP said.
As previously reported, higher-end Integrity servers are available. They can include Intel's newestwith 9MB of high-speed cache memory, as well as version 8.2 of HP's , which can now run on Itanium.
OpenVMS joins three other operating systems already available on the Integrity line: Microsoft Windows, Linux from Red Hat and Novell, and HP's version of Unix, called HP-UX.
Combinations of these four operating systems can be run on the same server through the use of technology called partitioning.
Some of those other operating systems also have gotten a boost. HP supports a pay-per-use program for Windows, letting customers pay on the basis of how much computing power a Windows partition uses. That can be substantially less expensive than buying on the basis of a server's total capacity.
In addition, through the use of SuSE Linux Enterprise Server 9 from Novell, Linux now can run on 16-processor Integrity servers instead of just eight-processor models, HP said. The improvement came through use of the 2.6 Linux kernel, which is scheduled for use in Red Hat Enterprise Linux in the first quarter of 2005.
A fifth operating system, NonStop, will arrive in mid-2005, HP said. It's used in very high-end specialty servers that require somewhat different hardware than the Integrity line, however.
HP has a collection of software called the Virtual Server Environment to improve how a single server juggles multiple jobs.
The company announced its Process Resource Manager 3.0, which automates allocation of resources such as memory, processor power and network bandwidth for HP-UX.
HP also announced version 3 of its HP-UX Workload Manager for automatically juggling priorities on one system and its Global Workload Manager doing the same across multiple servers running either HP-UX or Linux.
The faster processor boosts performance as much as 25 percent. New Integrity models with the chip include the dual-processor rx1620-2 starting at $4,119; the dual-processor rx2620-2 starting at $5,614; the four-processor rx4640-8 starting at $16,600; the eight-processor Integrity rx7620-16 starting at $18,995; the 16-processor rx8620-32 starting at $57,990; and the 64-processor Superdome starting at $185,252.
The systems also can accommodate doubled processor counts through the use of thetechnology.
