为减少存储管理费用进行IT结构重组

The Architecture
Over the past decade, data volume increased dramatically
while the cost for storage technology decreased almost as
quickly, making it feasible for companies to build larger and
more complex infrastructures. Whenever the demand for more
storage capacity surfaced, an IT organization could simply
order up the necessary hardware and quickly install it, efficiently
meeting the organization’s need in what appeared to be
a cost-effective manner.
Now these burgeoning storage infrastructures are demanding
more resources from already lean IT organizations. The technology
comes from a wide range of vendors, and requires advanced
skills and (often vendor-specific) tools to manage. Vendors have
tried to fill the void with an array of products that generally fall
short of providing a total solution. Although the SNIA is attempting
spend far too much of their time simply handling the day–
management of storage. In addition, most organizations
entirely focused on new deployments and seldom, if ever,
an application to see how it is using its assigned storage.
Cumbersome procedures are only a small part of the
The real issue is that storage management responsibilities
dispersed throughout the enterprise, becoming part
description for many IT functions. Even large companies
have a Storage Administrator have many other individuals
within the IT organization handling portions of storage management
for their own applications or servers on a regular
As a result, many companies have database administrators
performing capacity planning, systems administrators
trending and configuration management, and the application
support team, developing a disaster recovery plan.
Executive Overview
It is an accepted fact that companies today spend significantly more money managing their storage infrastructures than they do
the technology itself. The actual numbers are up for debate, with storage vendors claiming management-to-acquisition cost
high as 10 to 1, while industry analysts like Gartner peg it at a more conservative 3 to 1. Regardless of which estimate is correct,
is widespread agreement that storage management costs are too high, and climbing higher. The root causes of today’s unmanageable
storage environment are the architectural and organizational complexities that have naturally evolved over time as storage
increased and storage technology grew more powerful.
