FIVE STEPS FOR SUCCESSFUL SERVER CONSOLIDATION AND CAPACITY PLANNING

Five Steps for Successful Server Consolidation and Capacity Planning | Galileo Performance Explorer
GOALS FOR SERVER CONSOLIDATION AND CAPACITY PLANNING
• Eliminate multiple, individual servers and maximize available resources.
• Adequately support business expansion while reducing CAPEX and OPEX.
• Approach consolidation and capacity planning with a simple and thorough process, rather than treat it as a "black art."

THE 5 STEPS
There are five basic, but important steps:
• STEP 1: Define hosts/servers for consolidation analysis
• STEP 2: Define a time-frame (Baseline)
• STEP 3: Determine CPU, Memory, Network and Disk Usage
• STEP 4: Define Growth projection.
• STEP 5: Recommend Consolidation and Capacity Solutions

DEFINE HOSTS/SERVERS FOR CONSOLIDATION ANALYSIS
• Keep business strategies in mind.
• Thoroughly analyze the current IT environment and costs associated with it.
• Do more than just a census, think holistically and include CAPEX and well as OPEX.
• Think about leases and leasing or co-hosting.
• Consider the age of the current servers and the potential support or staffing problems to keep them operational.
• Consider constraints such as existing floor space requirements and power constraints.

• Correlate the business peaks and IT peaks.
• Make IT a good business partner: monitor your data center performance and capacity 24x7x365.
• Make accurate consolidation or expansion decisions based on that data.
• Use a tool like Galileo Performance Monitor to provide accurate information to base sound decisions on.
DEFINE A TIME-FRAME (BASELINE)STEP TWO

• If you do not have the appropriate data – consider installing a monitoring software and gather some data for the next 30 to 60 days to give you a baseline.
• It is best if this period includes business peaks and valleys.
• If not, use the baseline data to map to the business cycle.
DEFINE A TIME-FRAME (BASELINE)STEP TWO

• Are you moving any physical environments to virtual environments?
• Such a move is not a one to one correlation. For example, you must account for the doubling of network packet processing.

• Past performance data gives you a good perspective of the past — not necessarily the future.
• Align IT with the business plan to create a successful server consolidation and capacity planning strategy.

Without past performance data, try this algorithm:
• Use your Baseline and increase by 25%. (This gives you a base for the coming year.)
• Then, increase by 15% year-to-year over the next 3-5 years.
• The algorithm is not as accurate as the first approach, but without historical performance data – assumptions are necessary.
DEFINE GROWTH PROJECTIONSTEP FOUR
GROWTH = (B*1.25) * 1.15Y
B = Baseline, Y = Year

• This consolidation plan is based on a realistic assessment of the required capacity for support of the business plans.
• Build it to support the required availability, footprint, and performance requirements.
• Efficiently map out location, energy, and resource costs to optimize your CAPEX and OPEX.
