When we talk about the related products and scope of “storage”, storage media should
include more than tens or products such as: disk, magnetic tape, CD compact disc,
DVD, MO, optical fiber storage system, network storage system, disk array storage
system…, etc.; these products can be divided into optical storage and magnetic
storage components and equipments, etc. Since most of the current desktop
computers or server systems are based on hard disc as the major media for massive
storage, and the enterprise customer tends to use RAID disk array as storage system
for online storage and redundant, however, in order to distinguish and focus our
investigated topic, we will target at storage industry (Disk Storage System) based on
the application of hard disc.

In the whole storage industry, RAID is one of the most important core technologies,
RAID disk array controller card/device connects at one end to Host and at another end
to hard disc. Therefore, technologies such as the interface of RAID disk array controller
card, all kinds of support specs, related technologies, hard disc and the host are all
interrelated to each other. Currently, the mainstream interfaces between host and hard
disc are two types such as ATA (also known as IDE) and SCSI, however, for FC optical
fiber interface, due to its high cost, has been mostly used in the network storage
system of large enterprise. Currently, most consumer PCs (desktop PCs) adopt ATA
interface, but the servers in mid-sized enterprise adopt SCSI interface.

2.3 Input/Output (I/O) Protocol
The so-called I/O (Input/Output) means data input and output action, and Protocol is
used to define the common connection “standard” for input and output. The whole
storage system architecture can be mainly divided into two parts, one is the transfer
interface in between the computer server mainframe (Host) and RAID Controller end

(as in circle 1), another is the transfer interface at the in between the storage device
and the hard disc end (as in circle 2). Currently, the mainstream outer transfer

Storage component plays an important role in the whole storage market. Since it has
certain technological entrance barrier, it belongs to technology-intensive industry,
competitive yet cooperative relationship is maintained among the suppliers; meanwhile,

Storage component can be divided into four types:
1.
Semiconductor device:
It can be divided into IP Storage, InfiniBand, TCP Offload, Serial ATA(SATA), etc.
Interface adapter or chip.
2.
Disk:
Tape or hard disc, hard disc can have interfaces such as: ATA, SATA, SCSI, SAS,
FC.
3.
Host-based adapter (HBA):
It is an adapter installed at the host to provide redundant function to system RAID
disk array, good data I/O performance and more effective control on hard disc, it
is an adapter in between Host and hard disc (or other storage media). It can be
divided into SATA/ATA, SCSI and HBA of FC.
4.
RAID controller:
It is a disk array controller installed in the storage system, it mainly controls data
operation of RAID and control the storage device formed by several hard discs.

It can be divided into software and hardware (chip) type TOE, it is the
speedup processor of the internet packet of IP Storage, its main function
is to share the workload of the server so that server can put its attention
on executing other application functions and achieving a speed of
over Gbps.
3.1.2 Hard Disk
RAID is in charge of controlling the data I/O in between hard disc and host, and hard
disc takes charge the data storage capacity, Therefore, the future spec and technology
trend in hard disc has become an important index which affects industry development.
Hard disc mainly includes a disc, motor, access arm, read/write head, controller chip,
transmission interface port, power supply port, etc., the major transmission interface
includes ATA, SATA, SCSI, FC, wherein ATA almost occupies a high global market
share of 90% in the hard disc market, it is almost used for the PC market. However,
SCSI is used mostly in the enterprise customer, due to its high cost, FC interface is
used only for high level enterprise market, it only occupies 1% in the hard disc market.

SATA the optimum replacement for SCSI or FC. In the past, ATA hard disc is inferior to
SCSI in both speed or stability, plus the limitation in cable length, it is thus not widely
used in the enterprise storage environment, however, the new generation SATA
interface seems to re-write the hard disc history. SATA Workgroup has made a seven
year plan for SATA spec in one time, this includes the main specs of SATA first
generation (1.5Gb), second generation (3.0Gb) and third generation (6.0Gb), even the
related storage in NAS is planned, SATA is never inferior to SCSI in terms of its
superior transmission speed and more advanced functions. Most importantly, it inherits
the low price superiority of ATA, it is believed to gradually penetrates into the SCSI’s
application in enterprise storage market. The reasons are as in the followings:
„
ATA hard disc has become more stable and mature in technology.
„
Price superiority, with price of 2 to 3 times lower than SCSI.
„
Breakthrough design in spec and function.

the most importantly, protect all the data within the hard disc and provide a backup
mechanism of online backup so that a mission of non-stop operation can be achieved.
RAID HBA is an adapter controller inserted on the mother board, usually, there are
many interface ports (2 ports~12 ports) on the HBA to connect several hard discs, it
can be connected directly and internally to hard disc (mainly based on ATA, Serial ATA
or SCSI) or connected externally to outer equipments (it is normally based on SCSI
interface, but some suppliers plan to turn Serial ATA into externally connected
interface).
RAID HBA is usually used in large host or high level server in the past, and all are SCSI
interface, high cost is a natural thing. However, since PROMISE Technology Inc.
introduced RAID into the IDE/ATA market in 1997, RAID has become widely accepted
in the medium and small sized enterprise server environment and PC system. As
compared to traditional SCSI RAID, Serial ATA/ATA along with its cost superiority
(about 1/2 to 1/3 of SCSI RAID), is seen as one with future high growth in the industry.
Current RAID HBA can be divided into different interfaces such as: SCSI, ATA, Serial
ATA, FC.

3.1.4 RAID controller
As compared to host RAID HBA, RAID controller usually exists in a storage system
which is excluded from the server, it can be connected externally and serially to 15 sets
of device based on SCSI interface; normally, SCSI hard disc is adopted as the hard
disc within storage system, however, due to cost consideration, there is a trend that

3.2 Storage System/Subsystem
The storage environment in the past is simple, for the management convenience
purpose, general server will include storage function (host system integrates disk array
device); however, the expansion in digital data in recent years is too rapid, and under
the trend that the backup management function needed in the storage becomes more
本
and more complicated and hard disc capacity becomes larger and larger, storage
device is thus gradually separated from the host system to form an independent device.

Storage system can be installed inside the server, or can be connected externally to the
server. Generally, the target market of storage system follows the server market of the
enterprise, it can be briefly divided into work station/ small sized enterprise, medium
sized enterprise, large sized enterprise , etc.
3.2.1 Market segment and definition (1): target market
Storage systems are mostly connected or used in the server environment, based on
the deployment environment, storage market can be divided into small sized enterprise
(Entry-Level)→ medium sized enterprise (Mid-range level)→Large enterprise (High
level Enterprise), among them, the medium and small sized enterprise has the highest
growth potential (as shown in the figure), however, the growth in higher level or large
host is going to stay stagnant. The classification on storage system form IDC based on
the price (from hundreds of thousands to tens of millions) are roughly nine grades
(Brand 1~9), Dataquest further divide it into 6 grades based the number of hard disc
used (Class 1-6,hard disc ranging from 1~129 sets), we can thus see that most storage
systems are still used in the enterprise environment, and the host is mainly based on
high speed storage interface (such as SCSI or FC optical fiber); for the hard disc
interface used for storage, due to the continuous enhancement in stability and speed of
SATA hard disc as well as the concern for the reduction of IT total cost of ownership

(TCO), etc., it is no longer limited to the more expensive SCSI or FC optical fiber hard
disc; for example, CLARiiON of EMC is an optical fiber storage system where FC has
been converted to ATA hard disc, this proves that stable and low cost ATA, SATA hard
disc has been gradually applied to higher level FC storage system.

which possesses the industry standard, that is, the currently widely used TCP/IP or
optical fiber technology. No matter it’s the widely familiar NAS (Network-Attached
Storage) or SAN(Storage Area Network), since they possess both network connecting
function and become a merging version in application, they are no longer simply
independent architecture, therefore, Dataquest calls the integration system of NAS and
SAN as FAS. In the future, when internet and SAN standards from different suppliers
gets more integrated or when the product gets more stable, we believe that FAS market
will become more mature.
3.2.2.2 Direct-Attached storage system(DAS: Direct-Attached Storage)
DAS mainly means those storage systems without network connecting functions, these
include a host built in with RAID HBA card, or a storage device (with built in RAID
controller) which is independent from the server, they can be further divided into three
major types (please refer to chapter 3 for more details).
Take a glimpse at the current market, DAS is the most frequently adopted storage
solution currently, it occupies a market share of 63% of the overall storage market,
among them, SCSI RAID has a share of about 60%; however, since the new
generation Serial ATA has broken the limitations such as functions and transmission
methods inherent in traditional ATA, Serial ATA RAID is expected to rapidly replace ATA
RAID market and erode the market occupied by SCSI RAID. ATA RAID leading supplier

Scalability:
As internet data grows several times each year by following “Moore’s law”, storage
architecture changes its face too from “Server-Centric” to “Storage-Centric”. Therefore,
facing the trend of several times increase in the amount of future data, the scalability of
a storage system should be seen as a first priority; that is to say, how to let the storage
system in a company to own the maximum flexibility and scalability yet under the
minimum budget; and how to take care of also its compatibility to other system or
platform so that IT personnel can easily set up and manage the system without new
expense on the new installation.
z
Stability/Reliability:
It is a system that possesses Back-up capability and 100% Fault-Tolerant mechanism
so that it will not cause malfunctioned or damaged storage system due to the accident
caused by any component. Currently, the online hardware backup method is commonly
used to share the possible risk of malfunctioned machine, these include RAID storage

Availability:
It mainly the back-to-online and system operation recovery capability when system is
down, this is to prevent failure and to shorten the recovery time. For example, high
availability means the operation rate of the system is increased to 99.999%, this is

3.2.5.2 The emergence of network storage system NAS and SAN
There are two major interfaces storage system applied in the networking area: One is
FC, another is TCP/IP.
Although NAS uses network TCP/IP for data transmission, the File-based transmission
as well as Block-based transmission used for database data transmission obviously
face bottleneck. Due to its high total cost of ownership, FC can not be widely used in
the Fabric-Attached Storage market, some forecast that in the next few years, FC will
drop itself gradually from the mainstream market, it will be left limited to SAN
environment of large sized enterprise. For medium and small sized enterprises which
rely so much on standard Ethernet and internet protocol(IP), the more economical IP
Storage will be a best choice; the current iSCSI interface which is based on IP
technology has followed the existed Ethernet architecture and cheap trend and will
become the main storage system in low level SAN environment.
The major reasons are as in the followings:
1.
Ethernet is still the mainstream internet protocol currently used in the
enterprises.
2.
Ethernet installation is simpler than FC .
3.
Ethernet environment is mature, storage system can be plugged and played,
there is no additional re-learning cost.
4.
Ethernet related component is cheaper (Switch, Router, etc.)

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

In the pyramid industry, system giants gradually move from the second layer to the third
layer sub-industries, they step into storage software management market which has
higher profit. They try to create value through vertical integration and build up the
entrance barrier higher; for long term speaking, storage system giants will head
toward the service market of vertical integration such as: providing integrated and
value-added product and service such as: server, storage system, software and
hardware, network components.

Storage giants will focus on high level and high value-added market block, however,
to prevent the pressure of operation cost increase after vertical integration, the
upstream key components such as some key hardware components: RAID HBA,
Controller, etc. in the storage system should be outsourced to the ODM design

system nowadays.
Storage linking structure —DAS and FAS (NAS, SAN)
Based on storage system equipment as the center, it is the connecting method
among itself, the server (Host) and the network structure, it can be divided into three
major storage environment applications such as: DAS (Direct-Attached Storage),
NAS (Network-Attached Storage) and SAN (Storage Area Network). As
“network-oriented storage” trend becomes clearer, Dataquest has included, in its
newest report, NAS and SAN into FAS (Fabric-Attached Storage). Strictly speaking,
SAN means a storage architecture concept, DAS and NAS are storage system
devices, under the whole storage architecture environment, NAS can lie underneath
SAN and be merged with SAN, they do not repel each other. In general larger
enterprise, IT personnel will choose from these three storage methods for an
integrated use according to different scale and need.
The earliest storage system lives inside a large host, it is an independent storage
device, it is connected directly to the server host. Since it follows server host, it is
thus named DAS (Direct-Attached Storage), it is the earliest On-Line storage system.

Storage Industry Overview
However, as internet gets booming later on, the amount of data expands in several
times, digital information content (multimedia, audio and video, animation, etc.)
increases continuously, DAS storage can no longer handle the in-time expansion
issue in network era. Therefore, NAS (Network-Attached Storage) is thus a storage
product under network economy. However, there is still some limitations on NAS, for
example, its File-Based transmission method turns the original jammed information
本
highway in the internet worse; for continuous big file backup and simultaneous
accesses by multiple persons, the limited 10/100Mbps transmission efficiency of IP

is a big bottleneck, and the goal of concentrated management can not be reached.

4.1 DAS (Direct Attached Storage)
It is a storage system directly connected to the server (based mainly on SCSI protocol),
called DAS. DAS currently is still the mainstream of storage system, it
occupies about 60-70% of the whole storage system market. Since DAS is
connected to server directly and mostly connected through mature SCSI
technology, therefore, it is very easy to be installed and connected and easy
to be understood; it is easily to be adopted when the enterprise is installing

The integration trend f NAS and SAN= FAS
As mentioned before, Dataquest classifies NAS and SAN as inside FAS, this is a better

Fabric-Attached Storage concept were all based on Server-Centric, however, when

on NFS of Unix server or CIFS protocol of Windows SMB. Since it is connected directly
to IP local area network (LAN), not like DAS which is connected to server, therefore, it
is like ”network neighbor” to the user, access to the data is very convenient. To MIS, the
installation process and management are simple too, no high learning cost is
necessary. Therefore, they are mainly used in environments such as: medium and
small sized enterprise, departments with high need in file sharing, not too many servers,
or heterogeneous platform, they can be expanded continuously.
The followings are advantages of NAS:
1.
Since NAS is not connected to server, server’s performance is thus higher.
2.
It uses current mainstream TCP/IP network for installation, no new storage
architecture installation is needed, its complexity of introduction is much less than that
of SAN.
3.
It is compatible to heterogeneous platform and can be operated in different
operating system.
4.
Plug and Play, expandable, high flexibility.
5.
It is frequently used in low data amount but many persons environment, or larger
multimedia file which can not be transferred by Email, for example, Streaming,
Video/Audio or CAD/CAM.
6.
Low cost.

Storage Industry Overview
The disadvantages of NAS:
Since NAS is connected to IP network and used in LAN, local area network, or WAN,
wide area network; therefore, when there is a need on large data transfer, or file that
operation is needed, the bottleneck of insufficient bandwidth is thus easily met,
besides, the network resource will be occupied and network jam becomes inevitable.
Furthermore, NAS can not perform concentrated management or higher level virtual
本
resource management, it is kind of discrete single point storage.

4.2.2 SAN (Storage Area Network)
SAN is to build a high speed network storage architecture dedicated for data transfer. It
isolates each storage system which was originally separated to each server as a
Storage Pool, it can be connected to the server host through Switch or Flow Controller
in Fiber Channel, or connected to existed Ethernet through iSCSI (Internet Protocol
本
over SCSI) technology. The current market mainstream is Fiber Channel transmission
technology, its largest spec advantages are a transmission speed as high as 2Gbps,

and storage system such as: fiber interface card is needed in the server host, fiber
cable, Fiber Hub, Switch, Router, etc.; the basic cost will be more than one million NT
dollars, and the installation is complicated too, therefore, very few enterprises use SAN,
medium and small sized enterprise are even difficult to afford. SAN solution is
proposed by Fabric-Attached Storage company such as EMC in later 1990s, it’s not
long since its first use in the enterprise storage environment, therefore, there is no
uniform spec, protocol, standard or operation platform to be followed by enterprise;
therefore, the “compatibility” issue among devices and storage system need to be
considered during the purchase, however, the suppliers seem to notice this issue, they
gradually provide high integration storage solution which can be operated across
heterogeneous platforms.
The optimum SAN solution for medium and small sized enterprise: iSCSI
Since SAN is still immature in both technology and market, it is still in its infant stage,
each supplier has its standard and finds aggressively the support from other related
manufacturers so that it can lead the development of SAN. In order to prevent the
compatibility issue among different devices, IT personnel might have to purchase a
total solution instead of purchasing flexibly a single product. iSCSI emerges to solve
the above problem, it provides a cheaper SAN environment which does not goes
through fiber channel for medium and small sized enterprise.

Storage Industry Overview
iSCSI will be an important technology to bring up SAN application
iSCSI represents a standard communication protocol, it packs SCSI command into
TCP/IP packet, SCSI command is transferred through Block method in different IP
networks, therefore, it can speed up the data transfer in intranet, besides, the storage
can be managed remotely. It is generally known that iSCSI protocol will be the key
本
technology that will bring the rapid growth in local area network SAN, it is believed to
enhance the transfer function and efficiency of stored data. Due to the popularity of IP

iSCSI will have high growth in low level SAN market
Currently, SAN uses FC as the major transmission interface, however, the market is
concentrated on few large sized enterprises which can afford and have resource to
maintain and repair; this is because the introduction of FC SAN needs to pay not only
storage hardware such as: storage system, network Switch, Hub, etc., most importantly,

PROMISE Technology Inc., as a total solution provider in ATA/SATA RAID, has
become a leading global supplier in ATA/SATA RAID. PROMISE Technology Inc. is
one of the very few Taiwan’s enterprise that can stand at both ends of a “smile curve”,
that is, technology and marketing, it is a global enterprise that creates both high
added value and competitive superiority. PROMISE Technology Inc., with not only
solid technological background, but with its self brand strategy, has successfully
stood in the global market. Different from other Taiwan’s brand name in the global
market, PROMISE Technology Inc. uses a localization business operation strategy
and globalization thinking, has successfully built its global sales channel and opened
a global brand name without country border limitation. Its strategy emphasizes on
ODM, OEM as well as brand name, it keeps a close and good contact with the global
leading suppliers, it has successfully eliminated the barrier for becoming a global
name to Taiwan’s suppliers.
5.5 Strong global logistics, its marketing channels are well deployed.
PROMISE Technology Inc. has its business model of building global marketing sites
at US (America), Holland (Europe), Mainland China (the great China area), it not
only provides in time service to customer, but also successfully builds its superiority
of global logistics and localization marketing. In order to fully use its localization

alliance or contract is thus a major consideration, this is to reduce cost of ownership
and enhance the quality.
Since it is a trend to use long term contract as the mutual interest warranty when
storage component manufacturer cooperates with international giant supplier,
PROMISE Technology Inc. has cultivated storage industry for more than a decade,
with its long term customer basis, it owns obviously relative good condition and
superiority. PROMISE Technology Inc. has close and long-term cooperative
relationship with many international Tier 1 suppliers, from the upstream hard disc
and mother board giant suppliers to downstream PC or server giant suppliers such s:
Apple, Dell, Fujitsu, Fujitsu-Simens, HPQ, IBM, Intel, Maxtor, NEC, Seagate,
Western Digital, etc. PROMISE Technology Inc. has grasped the industry trend and
pulse for a long time, it has it own vertical integration technology, global marketing
channel and after-sales service; meanwhile, plus its strict requirement on product
quality, stability and compatibility, PROMISE not only becomes global leading
supplier in ATA RAID, but also is the assigned cooperative target by international
giant supplier, this means PROMISE Technology Inc. has built its important role and
position in the international storage market.

In storage system market, SATA RAID covers storage architecture of DAS, NAS and
SAN, more application markets are going to be covered by it (PROMISE Technology
Inc. will publish them in the future), for example, to replace the position of traditional
media (for example, the magnetic tape) in the storage market. In RAID HBA market
aspect, Serial ATA RAID not only will replace the original ATA market within five
years, but also will replace SCSI RAID HBA market; it will grow from the simple
application in low level personal or enterprise market to medium and high level
enterprise customer market and gradually replace SCSI RAID HBA in DAS market.
PROMISE Technology Inc. has grasped storage spec and industry pulse for a long
time, it leads the market to announce a complete series of Serial ATA RAID storage
in Computex last year, ranging from SATA RAID 0/1 solution: FastTrak S150
TX2plus (2 SATA port plus one ATA port), FastTrak S150 TX4 (4 SATA ports) to SATA
RAID 5 solution (4 SATA ports); its product has been adopted by international giant
supplier one after another due to its capability to launch new product in time, the
performance of the product becomes clearer. This fully shows that PROMISE
Technology Inc. can see clearly and deeply the future industry trend and grasp it so
as to stand at the leading position of the business.
