Storage Industry Overview

3.2.5.3 High level array system has entered its mature period, it has to face low

price competition pressure

Analysts forecast that the enterprise data grows at an annual rate of 80%, however, the

budget is not increased. This means hard disc gets larger in its capacity but the price

gets cheaper; as the technology and function of array system get more mature, it can

handle the need from large sized enterprise. This kind of trend will have three results

for the array system:

1. High level storage system becomes smaller and price competition becomes

inevitable.

2. Storage system will have relatively larger growth space in medium and low

level market.

3. Storage system in medium and low level market will catch some high level

functions but provide a solution of low price and complete function.

3.2.5.4 Virtualization, automatic management

RAID is itself a product of virtualization management concept. As hard disc capacity

gets larger and larger, smarter CIO values more on the so-called ROI of storage

capacity, that is, the utilization rate and efficiency of real data in storage system and the

economic performance cost of each storage unit an man power management cost.

Such market need on the “performance management” topic for related data will force

storage system to head toward a virtual management design with multiple elements.

3.2.5.5 Partial integration between NAS and SAN storage system

This part will be investigated in more details in the coming chapters.

3.2.6 The role of PROMISE Technology Inc. in the storage system market

PROMISE Technology Inc. integrates its professional technology for more than a

decade in ATA/SATA field and its strong global marketing capability, it positions itself as
