Common Myths about Capacity Management

MYTH 1: I don’t need to do PM until I have a problem
REALITY: Better to be proactive to predict the problem and implement a solution before it occurs

MYTH 2: Hardware is so cheap that Performance Management and Capacity Planning is unnecessary
REALITY: Total IT expenditure is still rising so that there is increased cost justification leverage

MYTH 3: Performance Management only needs to be done once a year
REALITY: It is best done as a continuous process of measuring, analysing, predicting and tracking

MYTH 4: Real time monitoring and tuning/ optimization is all you need
REALITY: You need a combination of detailed monitoring for analysis and aggregation for planning

MYTH 5: I can’t do Performance Management until I have tuned my system first
REALITY: The two processes work best together

MYTH 6: Management reporting to the web on a regular basis takes up too much time
REALITY: With the right tools this can be automated

MYTH 7: Analysis and interpretation of performance reports is too complex
REALITY: Automatic advice and exception reporting makes the data easy to understand

MYTH 8: Money is wasted on redundant or irrelevant equipment
REALITY: Excessive spending remains undetected until measured by capacity planning

MYTH 9: Network Capacity Plans need too much time to define traffic and workloads
REALITY: Networks are readily incremented and utilization can be assessed by bandwidth

MYTH 10: Service Level Agreements need too much effort to establish and track
