Book Description:

VMware Virtual SAN is a radically simple, hypervisor-converged storage, designed and optimized for vSphere virtual infrastructure. VMware introduced the software to help customers store more and more virtual machines. As data centers continue to evolve and grow, managing infrastructure becomes more challenging. Traditional storage solutions like monolithic storage arrays and complex management are often ill-suited to the needs of the modern data center. Software-defined storage solutions, like VMware Virtual SAN, integrate the storage side of the infrastructure with the server side, and can simplify management and improve flexibility

.VMware Virtual SAN (VSAN) is the converged storage solution for VMware vSphere
Integrated directly into the hypervisor, this is a native solution with no VM-based
intermediaries for storage delivery. As a result, VSAN is fast, simple to deploy and
.manage, and integrates tightly with the existing VMware vSphere product suite
As the solution is native to ESXi and runs on the hypervisor itself, its architecture is simplified
and the storage-delivery mechanism is tightly integrated and uniquely suited to the needs
of vSphere infrastructures. VSAN is an object-oriented storage solution, where each VM
is comprised of a number of objects physically distributed across the ESXi cluster. This
object-oriented nature means that access to your data happens natively, without the need
.for traditional intermediate storage protocols like iSCSI or Fibre Channel
VSAN's object-oriented nature also means that your VMs exist as a series of distributed
objects rather than a series of monolithic files. Whereas, with traditional storage, you have a
series of files (configuration files, virtual disks, swap, snapshots, and so on), with VSAN you
have a coordinated and related series of objects. These objects are a container for small
configuration files (the namespace object, also called VM Home), objects for each virtual
.disk, objects for each snapshot, and an object for the VM swap space
The key point when discussing VSAN's architecture, is how it integrates into the existing
hypervisor infrastructure to deliver the final service of any hypervisor: production virtual
machines. Behind this integration of the storage and compute virtualization layers is the
.notion of hyper-converged infrastructure. VSAN is one element of converged infrastructure
The goal of hyper-converged infrastructure is to abstract the traditional demarcations within
the environment (compute, network, and storage) by converging all aspects of the datacenter
.into a software-defined model with a centralized control plane and a distributed data/IO plane

VSAN is the storage element of the software-defined datacenter. User data (VMs) is abstracted
and distributed across the compute cluster. Each VM exists as a collection of related objects,
distributed optimally within the compute resources. VSAN natively integrates with vCenter
and its associated management tools. As a result, VSAN brings truly native, truly integrated
.management of the storage system into the existing and familiar vSphere operating structure
A major benefit to this new operating model of the storage system is its simplicity and
centralized management. VSAN obviates the need for traditional monolithic storage arrays
connected via traditional protocols. It also significantly improves on existing virtualization-centric
distributed storage solutions, typically delivered as virtual storage appliances (VSAs). Embedding
the distributed storage system into the hypervisor allows for gains in performance and
management. Native management through the vCenter Server means that storage for the
.virtual infrastructure can now be deployed and managed by the virtualization engineer
