Be proactive, not reactive
Many data center
administrators have seen their budgets shrink or at least stall out at current
levels, while the amount of complexity that consolidation, rising power
demands, and server virtualization bring keeps growing. Reduced resources make
managing the complexity in uncertain economic times even harder, especially
when the CIO and CEO are asking for less spending. It now makes all the more
sense to prioritize and get ahead of the rising needs of data centers — and to
stop being reactive, but rather, become proactive by better anticipating issues
before they happen.
Here are five tips to being
proactive and budget-aware.
Continue to focus on managing technology, processes, and people better. Don’t
fall back to a reactive state.
Track software and hardware assets through their complete lifecycle. This won’t
happen without effort.
Look for energy savings. Don’t stop at the data center, effective client-side
power management can yield large cost savings.
Look for areas to automate. Don’t settle for antiquated manual
processes.
Do continue with service delivery initiatives. Don’t
postpone.
Technology, processes, and people are the three pillars that constitute an IT
organization. Examining these aspects of the organization can produce measures
with good returns on investments (ROI).
Recovering Lost Assets
In the case of technology,
addressing a couple of key areas can help with an almost immediate ROI. The
first is sound asset management. Surprisingly, up to 1/3 of all the IT assets
within an organization go unaccounted, which causes a financial drain on a
business. It is imperative that an organization knows what assets it has, where
and how they are used, and how to get them off the books when they are no
longer being utilized.
Associated with assets costs are software licensing and renewals. As systems
have consolidated, especially with new virtualization technologies being
deployed tracking this information is harder. Has a business application been
moved from a physical server to a virtual server without adjusting the software
licenses? Not knowing what
technology is deployed within the corporate IT ecosystem and how it is used
increases the risk that an organization will pay substantially more for
licenses and renewals.
Maximizing and extending the life of hardware assets through automated
inventory management and tracking increases the value of those assets, which is
particularly important during poor economic times. An asset management tool can
help discover and more efficiently utilize all of the assets across the IT environment
and provide insight into the actual workings of the IT landscape. This
awareness is crucial to optimizing the lifecycle of existing equipment.
Finding and eliminating unused assets is even more important, given the surge
in server consolidation. Organizations need a good process to track the server
decommissioning process. Managing dormant, dead, or ghost servers can drive
real cost savings immediately. In some anecdotal cases, IT shops suggest that
30 percent of servers in large data centers are dead servers. These servers not
only take up valuable rack space but also waste precious data center energy and
cooling resources. Effective asset management helps control the end of life of
assets and drives cost savings by truly decommissioning assets and not having
them consume resources.
Given that governments around the world have taken an increasing stake
financially in the markets and individual businesses, corporations can expect
to see more regulations around governance and compliance. IT will not be immune
to this trend. Asset management tools and the associated processes will
position proactive operators for this clearly predictable forthcoming set of
requirements.
Tackling Power Management
Another key focus for real
savings is energy costs. While not all IT managers actually pay the energy
bill, helping to manage that expense is essential to aligning themselves with
the business needs of the company.
In the data center, according to the US Department of Energy, floor space
capacity is growing by approximately 10 percent per year for large enterprises,
and the amount of energy that these data centers consume continues to
soar. Typically, a data center consumes
10 to 100 times more energy per square foot than the average office
building. At current rates, these
power requirements could double in five years. According to IDC’s Worldwide Server Power and Cooling Expense
2006-2010, the nation spends $0.52 for power and
cooling for every dollar spent on a server and that is projected to grow toward
$0.716 per dollar spent on a server.
Getting a handle on these costs is a huge value to customers. This is not an
easy task, however. A recent survey conducted by Avocent of 300 data center IT
decision makers revealed that energy conservation is rated the most difficult
issue to resolve with current tools, while managing the total cost of power was
second. If IT could measure and monitor energy consumption, costs, and trends
across the data center, it could also analyze the overall cost and determine
how to better balance the power load, thus saving money.
Measuring and monitoring actual energy usage, identifying ghost servers, and
right sizing the power chain will enable IT administrators to operate more
equipment on their current energy budgets. In some cases these steps may extend
the life of the existing data center, delaying the capital outlay for an
extension or the need to build a new data center. Power management tools that
give real-time feedback to enable IT administrators to properly plan and manage
the power consumption can help delay new construction plans.
The Data Center and the Desktop
The data center is not the
only place where power savings can be realized. Significant savings can be
achieved on the desktop as well. However, according to the 451 Group, despite
the strong return on investment and immediate environmental benefits, desktop
power management is not widely used today.
The biggest deterrent to implementing power management policies on the desktop
has to do with the ongoing disconnect between the IT administrator, who has the
ability to impact power management, and the accountants, who pay the power
bills. Without easy-to-use reporting that clearly indicates how much money is
being saved, administrators are hesitant to deploy policies that have the
potential to impact system availability. But many policies can make use of some
safe activities — like placing the machine in a lower power state at night —
and turn those simple activities into cost savings. But accountantss will want
these savings measured to justify the investment. IT has to make sure that
proper measurements can be modeled prior to adoption, then measured after
adoption to ensure ROI.
Automate Processes
Processes in managing IT
present other potential opportunities in addition to those within the
technologies. Basic repetitive tasks often drain IT personnel resources.
However, automating processes can free up IT staff, allowing them to allocate
their time on higher value activities.
Process automation tools support the goals of clearly defining processes,
refining them, and then automating them. Deploying these types of tools and
putting rigor around IT management helps establish a consistent level of
operations especially across functional silos and reduces oversight. This will
directly affect efficiency.
A specific process area that has immediate ROI is in the area of service desk.
As IT organizations are forced to mature to align with business objectives, it
is imperative to have a process to drive efficiencies in providing IT as a
service. In many cases, IT organizations are very reactive in nature to
situations that drive inherent expense in environments, and they focus more on
the specific issue than the reliability of the entire IT service chain.
However, process frameworks like ITIL provide directions on how to create
business value from IT and service desk solutions, which provide a simple and
effective way to introduce these best practices.
Implementing the proper service desk solution can help organizations deliver
support services without a large enterprise budget, training, or knowledge
level. Putting more control in place can help can resolve support and service
issues more quickly through more efficient and higher quality problem solving
processes.
Productive Staff
The people factor is the
remaining important issue. Nobody wants to consider staff reductions but that
is always a concern in these economic times. To say the least, few firms are
looking at adding staff today.
In addition, reduced staffing levels exacerbate the problems caused by
substantial growth in the IT environment both in the data center and in the
client environment. The numbers of new types of devices is huge and includes
PDAs, mobile devices, servers, and appliances in the data center. All the
operating environments and virtualized environments running on that equipment
compound the problem, increasing the need to manage IT environments as
efficiently as possible to maximize the productivity of existing
staff.
Now is the time to investigate tools that will help increase efficiency and
save time by providing an efficient and complete management solution to reduce
complexity. It is critical that these tools encompass complex environments,
support the process automation focus, and work in conjunction with service desk
solutions. Delivering these types of systems management capabilities can lead
to great increases in staff productivity wall.
IT is positioned to be a leader in the sustainability and recovery of
businesses. With proper focus on the key aspects of the technology, the
processes, and the people that make up IT, IT can align itself with the needs
of the business.
Avocent offers one set of solutions around asset management and power that can
help organizations get substantial and immediate savings. Look at improving
processes through automation and through implementing a comprehensive service
desk solution. Lastly, bring all of these things together with robust systems
management solutions that help to drive up staffing productivity. It is these
types of activities that will help IT organizations weather this economic storm
and position the businesses for growth in the future.
