Storage and Networks – The Dilemma


  • pg 1
									        Primex Technology Innostorage NAS

Enhancements in Network Attached Storage (NAS) have brought this technology
from disk storage directly attached to the network to highly flexible storage
appliances that can serve a multitude of user needs with the simplicity of “plug
on the network” installation. NAS devices can now be truly multi-purpose,
offering significant reductions in the cost of providing the data storage
requirements for many applications.

Storage and Networks – The Dilemma
In today's data rich environment, multiple users work on a variety of workstation
operating systems – Windows, Mac, Novell and Unix – and require high speed,
simultaneous access to shared data. This data knows no economic slowdown.
The tremendous growth of business-critical data and the expectation that
everything - data and applications - must be available and accessible around the
clock is driving an extraordinary demand for storage. The Internet, huge digital,
audio, and video files, email archives (that are never deleted), and massive
databases are just a few of the applications that continue to drive this explosion.

Peripheral Concepts, a market research firm, pegs storage growth at more than
60% compounded annually.         AIISAN Research states that the amount of
corporate data is doubling every six months. By the end of 2002, enterprises are
expected to consume 1.4 million terabytes of storage annually – 12 times the
amount consumed in 1998.

It's not amassing data that has become the problem. Managing and controlling
all this information, software and digital content is the major issue for network
administrators. With network content expected to continue to expand at
explosive rates over the next five years, analysts predict that storage will account
for 75% of all computer hardware expenditures. This expansion makes it
increasingly important for IT professionals to develop a comprehensive strategy
designed to optimize network infrastructures and storage solutions that include
scalability, reliability, performance, availability, affordability and manageability.

The traditional way of storing data – adding more hard disks, RAIDs, or optical to
existing servers or simply adding more general purpose servers – actually
reduces performance, accessibility, reliability, productivity, and substantially
increases the Total Cost of Ownership (TCO). TCO encompasses more than just
simply the money spent on the actual storage component, it includes hardware
cost, cost to deploy, downtime and productivity loss, cost to manage and cost to
maintain. IDC estimates 80% of the total cost of ownership for adding storage to
a general purpose server is the time spent by skilled IT professionals to install,
maintain, administer and keep server attached storage running smoothly. In
today’s environment of corporate cost containment and streamlined IT staffs this
80% figure must be taken into account when determining the comprehensive
strategy for the deployment of storage solutions.

Storage and Networks – The Challenge
Direct attached storage (DAS) was developed in the mainframe environment
where networking was quite simple, distributed computing did not exist,
heterogeneous client support was not an issue and host interconnects and
operating systems were limited. With the advent of network infrastructures,
distributed applications, multiple operating systems and numerous host
attachments (numerous versions of SCSI, Fibre Channel), adding storage in this
environment has become much more complex and expensive. Even with these
complexities, today, 95% of storage devices are still directly attached to a server.
However, with weak storage interconnect standards (SCSI, FC and others), and
DAS vendors constantly having to re-qualify their storage subsystems with each
revision of a server’s operating system software – requiring special host
software, firmware and new installation, this is quickly changing. Dataquest has
predicted a paradigm shift from DAS to NAS, indicating that 95% of the DAS
storage market will be eclipsed by NAS over then next 5 years. IDC concurs
indicating an explosive growth in NAS, growing from $781 million in 1999 to over
$6.7 billion in 2003. All demonstrate the advent and wide spread deployment of
Network Attached Storage supported workgroup clusters with priorities for
heterogeneous file sharing, interoperability, reliability, high performance,
scalability, and cost savings. Equally important, NAS provides reduced IT
management, centralized administration and increased availability – supporting
today’s corporate cost containment, streamlining IT staffing and lowering TCO

Total Cost of Ownership High Low
Today, businesses need fast, reliable access to data. They need to be able to
install and maintain storage easily with minimum downtime and low
administrative overhead. Users need access to shared data in a heterogeneous
environment, with access to data from anywhere in the world, 24/7. NAS
provides all of these requirements and because NAS moves storage to a
specialized appliance, general-purpose servers are free to service other
applications and tasks more efficiently. By removing storage access and
management from the general-purpose application server, both applications and
data can be served faster, since they will no longer be competing for the same
processing resources, significantly increasing user productivity, throughput and
greatly reducing TCO.
Deploy Storage To Where You Need It
Its easy to understand why NAS Appliances are gaining appeal with business of
all sizes – simplicity of installation, operation and administration, low cost of
ownership and the commitment to support corporate cost containment and
streamlined IT staffing. However, the majority of NAS appliances on the market
are low-end disk storage or mid to high-end RAID storage devices, meeting only
a portion of corporate data storage requirements. While these devices are
excellent for providing additional disk storage they are lacking in TOTAL
