With the release of VSAN, VMware fulfills the true software-defined data center with the combination of virtualized compute, network and storage. After VSAN release, I will definitely say that buying storage for your infrastructure is not only limited to the storage vendors but also VSAN will play a major role because which is part of hypervisor after vSphere 5.5 Update 1 onwards. Virtual SAN 5.5 is a new hypervisor-converged storage tier that extends the vSphere hypervisor to pool server-side magnetic disks (HDDs) and solid-state drives (SSDs). By clustering server-side HDDs and SSDs, Virtual SAN creates a distributed shared datastore designed and optimized for virtual environments.Virtual SAN is a standalone product that is sold separate from vSphere and requires its own license key.
- Minimum of 3 ESXi 5.5 hosts with all contributing local disks (1 SSD and 1 HDD) to VSAN cluster
- Minimum 4 GB of RAM for ESXi host
- ESXi host should be managed by vCenter Server 5.5 and It should be configured as Virtual SAN cluster
- Each ESXi host must have minimum of single 1 Gb Ethernet adapter available solely for the use of virtual SAN
- At least 1 SAS or SATA solid state Drive (SSD) should be part of each ESXi host with SSD is not claimed by vSphere Flash Read Cache
VSAN with GA release, It supports around 32 Hosts, 3200 Virtual Machines, 2M Iops and 4.4 petabytes. It is really scalable and provides the scalability as like an enterprise storage.

A Virtual SAN Ready Node is a predefined combination of server hardware while a Ready Block is a predefined set of servers for use with VMware Virtual SAN. Configurations are based on server vendor validated configurations that include specific HDD, Flash and IO Controller components certified for Virtual SAN, and available on the VMware Compatibility Guide.
