Welcome to Capacity Management Blog

Given the intrerest in capacity management for servers, networks and infrastructure caused by heat/power, data centre space, and sheer IT complexity, I thought it the right time to write a blog with all the resources, tools and information for Capacity Management in one place. the sort of site which should exist, but never did: especially for Investment Banks.

Blog characteristics:

• Which isn't from a vendor.
• Which is free
• Which is unbiased*

[Why do I concentrate on investment banks: i) they have the budgets ii) they have the most interesting problems. Of course, if I can track down interesting non-banking tales, I will include those as well.]

Some general stuff which I will always cover:

• Capacity Management Industry acquisitions/mergers/sell-offs/de-mergers/chatper 11 [you know who you are]
• Hardware vendor events of interest to Capacity Planners, Performance Analysts
• A dictionary of definitions of Capacity Planning and all its related terms
• What is Performance Analysis
• What is Capacity Planning
• What is Workload classification
• Computer Measurement Group (interesting non-mainframe articles only please)

Some specialised stuff which I will lob in from time to time

• Virtualisation: how to analyze and capacity plan for enterprises wishing to move to a virtualised environment without causing a virtual headache.
• Blades: Capacity Planning, Performance Analysis specifically:
• Benchmarks: what the heck is going on these days?
• Queueing theory: where does capacity planning come from? Do all the mathematical formulae designed for manframe and VAXen still add up in today's world.
• Horror stories: case studies with the names removed and altered to protect the guilty.
• Vendor analysis: good bad and indifferent.
• ITIL: what is going on?
• CPU differentiation between vendor

* unbiased = regarding all the vendors on the same evolutionary scale until proven otherwise
