HP, HITACHI, LTD. AND HITACHI DATA SYSTEMS SIGN JOINT TECHNOLOGY AND OEM AGREEMENTS FOR HIGH-END, MULTIPLATFORM STORAGE SYSTEM

Agreements Signal New Strategy for HP in Mission-critical Enterprise Storage; First Result is SAN-ready HP SureStore E Disk Array MC256

	NEW YORK, May 5, 1999 -- Hewlett-Packard Company and Hitachi, Ltd., 
in conjunction with its global marketing arm, Hitachi Data Systems, today 
announced joint technology and original equipment manufacturer (OEM) 
agreements for enterprise-storage subsystems directed at the burgeoning 
enterprise-storage and storage area network (SAN) markets.  The announcement 
was made here at a press conference.

Joint Technology Agreement (JTA)

	HP and Hitachi, Ltd. have had a very successful nine-year technology 
relationship, starting with development cooperation in the areas of PA-RISC(1), 
UNIX(R) systems and HP-UX(2).  This JTA expands these areas of collaboration to 
include enterprise-storage solutions.

	Under the terms of the JTA, HP and Hitachi, Ltd. research and development 
organizations already have started to cooperate on the design, development and 
enhancement of enterprise-storage projects.  Initial results of this agreement are 
incorporated into the HP SureStore E Disk Array MC256 (see today's related 
announcement).  Future efforts will cover a broad range of storage, SAN and 
storage-management products.  These efforts will result in products that may be 
manufactured by HP or Hitachi, Ltd.

OEM Agreement

	Under the terms of the three-year OEM agreement, HP will OEM Hitachi, 
Ltd.'s high-end array technology products, cooperatively enhancing them with 
HP-contributed firmware and Fibre Channel technology for improved open-system 
performance, support for system consolidation and SAN interoperability.  HP also 
will OEM several storage-management applications to enable local and remote 
data mirroring, interoperating system data transfers, and centralized array 
management.  HP will integrate this software into its new HP SureStore E Storage 
Node Manager software as well as HP OpenView OmniBack II software to deliver 
zero-downtime backup solutions for SAP and Oracle(R) applications.

	HP also will leverage Hitachi, Ltd.'s high-quality manufacturing facilities 
and efficient supply-chain management, allowing optimized availability and 
flexibility in delivering tailored MC256-based solutions to enterprise customers.

	The MC256 will be the premier multiplatform high-end solution in the 
HP SureStore E storage product family.  The HP SureStore E product line 
promises enterprise customers "Stress-Free Storage ... Guaranteed" and is tightly 
integrated with HP Equation SAN-based, intelligent-storage architecture, also 
announced today.

	Furthermore, Hitachi Data Systems was named an authorized value-added 
reseller in a number of countries for the MC256 as well as other HP 
Equation-based storage solutions, allowing Hitachi Data Systems customers access 
to the benefits of the MC256.  

	"With storage availability and storage networks so crucial to IT strategy, HP 
is providing its customers with the industry's strongest line of storage solutions for 
the enterprise," said Bill Russell, executive vice president and chief operating 
officer of Enterprise Computing Solutions.  "Working with Hitachi, Ltd. will 
enable us to deliver an unmatched high-end disk array that meets our customers' 
high-availability expectations.  The centralized manageability, high-performance 
design and open architecture of the MC256 make it ideal for customers that are 
deploying enterprise-storage solutions."

	"This alliance leverages the complementary strengths of Hitachi, Ltd. and 
HP.  Together, we will deliver the best enterprise-storage technology for the 
increasingly heterogeneous computing environment," said Masaaki Hayashi, 
Hitachi, Ltd.'s senior corporate officer and group president of the Computer 
Products Group.  "Customers can now rest assured that their valuable information 
resources are continually available and protected."

	"I believe that this agreement is absolutely the right thing for HP and its 
enterprise customers," said David Hill, senior analyst with Aberdeen Group.  "HP 
has continually demonstrated that it is committed to doing whatever it believes is 
in the best interest of its storage customers.  Hitachi, Ltd. is a great choice as the 
core engine to help provide an open, high-end disk array for customers' future 
high-availability needs."
