Information is the lifeblood
of every modern business. Today’s business managers are more
dependent than ever on the ability to exploit information to
improve business performance and achieve competitive advantage. In practical
business terms, a reliable, flexible, scalable,
secure information storage strategy - and supporting storage-centric information infrastructure - is a requirement for success in
today’s rapidly-changing markets.
Ironically,
most
organizations still lack a
long-term strategy for managing their information
assets. Scarcity of skilled resources, lack of knowledge, cost and
time pressures, and other urgent priorities prevent them from
successfully transitioning to the next-generation of
storage-centric, information-rich enterprise computing environments.
Furthermore, most IT organizations have their hands full just
managing the
infrastructure in place today.
It is not uncommon for companies to have 10s or 100s of
under-utilized servers and storage devices scattered across their
operations, each with different combinations of storage devices,
applications, operating systems, management platforms, etc. Issues of data sharing,
protection, and management, information security, service
levels,
and integration consume all available IT resources.
STORAGE-CENTRIC
INFORMATION INFRASTRUCTURE
Storage is moving out of the
back room and to the forefront. Forward- looking organizations have
begun to organize their enterprise information architecture around
their storage infrastructure. As the keeper of enterprise
information assets, the storage infrastructure is the
information infrastructure - the
central point around which the remainder of the computing
environment - servers, networks, PCs and access devices - is organized.
In recent years, storage technology
developments have responded to user requirements for improved
sharing, management, and protection of enterprise data assets,
through the introduction of innovations including:
- Storage-Area Networks (SANs):
Storage has evolved from separate "islands" directly
attached to a dedicated server (DAS), to a shared resource
accessible from a dedicated, high-speed network, making data
available to a variety of heterogeneous servers, operating
platforms, and enterprise applications.
- Network-attached Storage
(NAS):
Specialized storage protocols have made remote storage available
to servers over industry-standard IP networks, enabling
flexible, shared access to information wherever the network
extends.
- Policy-based Storage
Management:
An innovation in storage management platforms that abstracts
storage management tasks from the underlying platforms, and
automates the execution of tasks based upon higher-level
policies and thresholds.
- Storage Virtualization: A more
recent introduction which makes network-connected storage
subsystems easier to optimize and manage by "pooling"
storage assets and presenting them as a common resource to the
administrator.
OVERCOMING
STORAGE MANAGEMENT
CHALLENGES
As they look to standardize
their operations and cut costs, organizations are increasingly
challenged by their storage resource and management
requirements. Demand
for capacity is exploding, end-user service level expectations are
rising, budgets are frozen or falling, and IT managers are under
pressure to respond to business changes. The scope and growing
complexity of storage is outpacing organization's ability to manage it
cost-effectively.
Facing up to these
challenges, organizations are aggressively looking at upgrading their
server and storage infrastructure via:
-
Server
Consolidation: Reducing the number and variety of server and
operating platforms in place, centralizing server resources to
facilitate improved security and management, and standardizing
management platforms
and tools.
-
Storage
Consolidation: Shifting from Direct-Attached (DAS) to
networked storage (SAN, NAS) architectures, improving
information access, storage performance and availability, and
facilitating centralized storage management policies and
frameworks.
-
Backup
Consolidation: In line with server and storage
consolidation, reducing the # of backup platforms in place, and
standardizing on media and management platforms, in order to
improve reliability, and cut costs.
More
recently, organizations were reminded of the need to implement more
robust Disaster Recovery (DR) and Business Continuity (BC)
strategies. Consolidating and standardizing server and storage
platforms dramatically improves DR/BC planning at the information layer,
because common procedures can be applied to ensure that all critical
enterprise data are protected, whether by backup, mirroring,
replication, or other techniques.
