Getting Started with VMware Virtual SAN
Virtual SAN is without a doubt the latest fad in the virtualization arena. The best part about VSAN solutions is the fact that a near-Flash performance is achieved with only a marginal percentage of Flash storage. And all this without noticeably compromising vSphere's exquisite feature set and its interoperability with other products from VMware. This book covers the fundamental aspects of software-defined storage, including its evolution and its role in a software-defined data center. You will gain a complete understanding of VMware Virtual SAN architecture, its components, and how it is put together. The sizing and profiling of virtual machines are also covered in detail. The book explores your options in choosing the type of Virtual SAN and deploys a simple setup that will demonstrate the workflow of a VSAN deployment. ...

Agile Performance Improvement
Agile Performance Improvement demonstrates the mutual benefits that accrue to the worlds of performance consulting and agile software development when the values and principles of both are blended synergistically under the guidance of practitioners skilled in both. The agile performance improvement model blends the principles of human performance technology with the frameworks and practices of Agile. The result is an approach that maximizes the value of interactions among the consultant, the work team, and the customer. Unlike traditional end-to-end waterfall processes, agile performance improvement delivers value continuously and in small increments, relentlessly focusing on outcomes of value to the customer. Building on structures of Agile that are used in software development, such as Scrum, the agile performance improvement model considers the human component of holistic solutions in establishing a continuous stream of value. ...
