The Performance Analysis Service (PAS) collects system performance information. This information is used to recommend areas where systems are over (or under) provisioned, systems that would benefit from virtualisation and where rightsizing would provide overall performance benefits.
The move to Server Virtualisation provides a whole range of benefits to organisations managing ICT infrastructure. However, by its very nature,which is exploiting the management of mixed workloads on shared physical infrastructure, virtualisation reintroduces the requirements for disciplines that were traditionally associated with the mainframe world, such as:
The nature of virtualisation also makes problem diagnosis more complex to manage where all server and storage resources are in a virtualised and shared infrastructure.
The performance analysis tools provided by ICT Analytics help to address many of these issues for customers who are planning to virtualise their environments, or who already have either partly or fully virtualised infrastructures.
The process simply involves downloading and running the data collector which collects performance statistics for a representative time period on the systems to be analysed. These flat files just need to be uploaded to ICT Analytics from which a range of online and offline services can be provided:
These services include:
An additional IOTrace analysis service is also available to allow detailed reporting of exact IO profiles and allow the following activities:
