BOOK: VMware vSAN 8 Express Storage Architecture (ESA) Deep Dive

The modern data center must adapt to these new operational requirements – agility and flexibility – while meeting stringent cost requirements during times of uncertain economic outlook. Running mission-critical applications on VMware vSAN 8 with Express Storage Architecture provides customers with agile, high-performance infrastructure that enables simplified operations, lower costs, and hybrid cloud-ready architecture. 

How does the vSAN Express Storage Architecture compare with the classic storage architecture of vSAN?  At a high level, the original storage architecture of vSAN was a two-tier architecture designed to accommodate a wide-ranging set of older storage devices, while the vSAN Express Storage Architecture in vSAN 8 is a single-tier architecture optimized for high-performance NVMe-based TLC flash devices for both on-premises environments, and for the hyper-scale public clouds.  With vSAN 8, VMware gives you the opportunity to select which architecture best suits your existing hardware, while allowing you to deploy new clusters with unprecedented levels of performance.  While the vSAN Express Storage Architecture is the future of vSAN, VMware customers should take great comfort that the original storage architecture of vSAN can be used side by side with the ESA and will be supported for many years to come.

VMware’s vSAN has rapidly proven itself in environments ranging from hospitals to oil rigs to e-commerce platforms and is the market leader in the hyper-converged space. Along the way, the world of IT has rapidly changed, not just from a software point of view, but also from a hardware perspective. With vSAN 8.0 VMware brought a new architecture to market called vSAN Express Storage Architecture (ESA). This architecture is highly optimized for today’s world of data center resources, be it CPU, memory, networking, or NVMe-based flash storage.

The authors of the vSAN Deep Dive have thoroughly updated their definitive guide to this transformative technology. Writing for vSphere administrators, architects, and consultants, Cormac Hogan, Duncan Epping, and Pete Koehler explain what vSAN ESA is, why the architecture has changed, what it now offers, and how to gain maximum value from it. The book offers expert insight into preparation, installation, configuration, policies, provisioning, clusters, architecture, and more. You’ll also find practical guidance for using all data services, stretched clusters, two-node configurations, and cloud-native storage services.
