HITACHI AND TROIKA DEMONSTRATE PLATFORM FOR DATA MINING

Hitachi Data Systems, a wholly owned subsidiary of Hitachi Ltd, and privately held Troika Networks Inc, an emerging-growth server and storage networking company, have teamed up at the Storage Networking World conference being held here this week to present a demonstration of advanced storage networking technology that dramatically increases the return on investment in data mining and other business-intelligence applications resulting from better CPU resource utilization.

The two companies collaborated on the design and implementation of a Storage Area Network (SAN), augmented with server networking functions that creates a single-wire network for data movement. The new technology reduces -- by ratios as large as 25 to 1 -- the processing overhead that network servers must devote to data-movement tasks. As a result, a much larger percentage of server resources can be used for application computing to get increased business value from the data.

The SAN built by Hitachi Data Systems and Troika Networks to host a highperformance data-mining demonstration at Storage Networking World is integrated into a larger SAN fabric there used to demonstrate efficient configurations for LAN-free backup, server-free backup, tape vaulting and archiving, and storage consolidation. This massive demonstration of SANcomponent interoperability and function was spearheaded by Brocade and made possible through cooperative efforts of ADIC, Brocade, Chaparral, CNT, CommVault, Compaq, Crossroads, Emulex, EuroLogic, Hitachi Data Systems, InterSAN, JNI, Legato, SpectraLogic, StorageTek, Troika Networks, and Veritas.

Key to the accelerated performance of the data mining application is the Troika SAN Controller, an intelligent Host Bus Adapter (HBA) designed to provide both server and storage networking on a single wire and use minimal host processing power. The controller serves as the interface between the network servers and the SAN switching fabric. This technology is the first in the world to enable three popular protocols for packaging and routing network data -- SCSI, IP, and VI Architecture -- to converge onto a single Fibre Channel wire. Among the visible results of this multi-protocol convergence is a significant reduction in network complexity and cabling, leading to lower installation and data management costs.

"The breakthroughs that Hitachi Data Systems and Troika are demonstrating, using Troika's intelligent SAN Controller and Hitachi server and storage systems, include the capability of using the same open standard interconnects for both storage and server networking on a single wire. The dramatic reduction in CPU utilization is an unprecedented benefit that significantly optimizes the use of data network resources," said Alan Skidmore, president and CEO of Troika Networks. "IT managers and service providers will enjoy reduced total cost of ownership and training by using a single infrastructure. At the same time they can support scaling data mining and e-business applications and an increased number of users."

To experience first-hand the benefits of a multi-protocol controller in a SAN environment, attendees at Storage Networking World are able to participate in a data mining application using the DB2 Universal Database Extended Enterprise Edition, with the contents of the database spread across a cluster of Windows NT servers. This massively parallel configuration enables the system to scan the database at rates of up to one million rows of information per second -- ten to twenty times faster than what is experienced in conventional system configurations.

Hu Yoshida, Hitachi Data Systems vice president for Data Network Solutions, commented, "Within a very short time SAN technology has progressed from being merely an industry buzz word to the point where it is being widely adopted throughout the IT world. IT managers and business executives are recognizing its benefits in maintaining and protecting their vast stores of critical data, but they are also experiencing even greater benefits by using SANs to exploit the value of this data for business success. We're pleased to team with Troika and our other SAN alliance partners to show the astonishing value that SAN technology brings to real-world business applications like data mining."

The SAN configuration demonstrated by Hitachi Data Systems and Troika Networks at Storage Networking World includes a cluster of four-way Windows NT servers, a Hitachi Freedom Storage 7700E subsystem and a Hitachi Freedom Storage 5800 subsystem. Data is routed between the servers and between the servers and storage subsystems via Brocade switches. Veritas software is used to manage the backup of data to automated tape subsystems. The Troika Controller detects which protocol is associated with each packet of data it receives and directs it to an appropriate destination. The choice of SCSI, IP, or VI protocol depends on characteristics of the data being transferred:

• Bulk data is transferred at high speed with low CPU utilization from server to server, via the TROIKA controller, through the SAN switching fabric, using the Virtual Interface Architecture (VI) protocol.
• System commands are transferred from server to server through the SAN switching fabric using the Internet Protocol (IP).
• Storage data is transferred between multiple servers and multiple storage subsystems through the FCP/Small Computer System Interface (SCSI) protocol.
