It’s not uncommon for different teams to be managing the virtual switch and physical switch configurations. This can make it very difficult to troubleshoot unless each configuration parameter has been gone through manually. There have been enhancements to the vSphere Distributed Switch over the past few years to address these operational challenges.

What’s the difference between high availability and fault tolerance in VMware vSphere? This article elaborates on first configuring high availability and then layer on the fault tolerance capability. Learn more.

A gap analysis is a tool that ITIL recommends organizations use to compare their current state to some future desired state.

Many I&O leaders and customers see little value from investments in ITIL. Not getting the Return on Investment (ROI) you expect normally comes from using ITIL incorrectly. You, your staff, and your customers must share the same goals and understand exactly what to expect from your ITIL investments. The goal of ITIL is not “business and IT alignment” or “competitive advantage from IT investments.” Instead, its first goal is to stabilize service operation. This builds a base for the second goal: increasing value through service optimization. You must have clear-cut, documented, and managed expectations for each activity, and order is vital. Success requires that you stabilize service delivery before trying to optimize. Focusing on the correct goal and linking each ITIL task to that goal is the correct use of ITIL.

ITIL is generally not prescriptive. In reality, the CSI Register at any given organization might look significantly different than the example given in the CSI book. The fields given in this example are important. 

Resource Pools are often misunderstood, disliked, and untrusted by vSphere Administrators. However, resource pools can be very useful tools for administrators who want to configure resource management without having to individually configure each VM. This leads to the administrator’s desire to explore the proper usage of resource pools.

Organizations that plan for and conduct supplier management according to defined processes and boundaries are more likely to receive predictable, high-quality goods and services from their suppliers in a timely manner.

Previously I discussed service providers and their risks in the example of my involvement with a landscaping company. ITIL clearly states that services, “…deliver value to customers by facilitating outcomes customers want to achieve…” However, sometimes organizations and people focus on outputs as opposed to outcomes, which sacrifices some of the value of the service. This leads to a question, what is the difference between an outcome and an output?

What's the correct sequence of activities for handling an incident? Find out why categorization occurs before initial diagnosis in the ITIL incident management process flow so you can answer this common ITIL Foundation exam question.

As long as I've been involved in service management, one of the perennial debates that's really never been resolved focuses around how many discrete processes ITIL describes. No such single list exists in the ITIL core books. However, section 4.1 of each of the ITIL 2011 core books shows the processes described within that specific book. When we deliver accredited ITIL training, if it is describe in section 4.1 of any of the ITIL core books, then it is considered a "process".
