Additional information on the enterprise storage market, including an in-depth overview of the technically advanced and unsurpassed software solutions available from Hitachi Data Systems, is available in the companion publication, the Hitachi Freedom Storage Software Solutions Guide. This document is downloadable in PDF format from www.hds.com. The report contains expert guidelines regarding industry-leading software solutions suites from Hitachi Data Systems for storage management, business continuity, performance enhancement, backup and recovery, and data transfer. It also compares the Hitachi Data Systems solutions to the major competitive software solutions and drills down into specifics.

Since enterprise storage features are increasingly required in the modular storage

market, additional information on the Hitachi Freedom Storage Thunder 9500 VSeries systems is available in a separate report entitled the Hitachi Freedom Storage Thunder 9500 V Series Architecture Guide. The Thunder 9500 V Series are modular (midrange) RAID storage systems designed for use in heterogeneous open systems computing environments and targeted at the e-commerce, Web serving, and data warehousing applications. The Thunder 9500 V Series storage systems are the only modular products that truly deliver large, enterprise-level features with a midrange package and price.

If further information is required, Hitachi Data Systems representatives can provide specialized presentations, reports, and expert knowledge on the topics contained in this series of reports.

Reduced TCO

Bandwidth contention in a shared-bus architecture serves as a limit to data hyper- consolidation initiatives and limits the enterprise’s ability to reduce TCO. Figure 4 illustrates that a recent survey showed that actual deployed average capacity of Lightning 9980V systems and Lightning 9970V systems exceeded that of fixed-bus systems by a factor of 2.5x. Since the Lightning 9980V systems and Lightning 9970V systems nearly double internal bandwidth of our earlier enterprise-level systems, it is clear that obstacles to massive consolidation projects will be removed. This is especially true when the Hitachi industry- unique “virtual” Fibre Channel port feature of the Lightning 9900 V Series is considered.

The major objective of massive consolidation is to keep up with exploding storage capacities without increasing head count and deploying staff to address the application backlog. With the Lightning 9900 V Series, TCO can be reduced not only through virtualization but also by:

Reduced network complexity with fewer switches, connections

Simplified and automated management tools and software

Lower licensing, maintenance charges, and environmental costs

2Some competitive products do not have dual cache like the Hitachi Freedom Storage Lightning 9900 V Series. If there is an unrecoverable error in cache, there is no duplicate backup copy. With these products there is an increased risk of lost data, especially if the loss occurs in the hardware status area. The Lightning 9900 V Series does not have this problem since all status areas and write data are duplexed. Although a minor concern to some given the low probability of occurrence, the thought of data loss is never comforting to enterprise executives charged with 24/7 operations.
