VMware Virtual SAN is a new software-defined storage tier for VMware vSphere, bringing the benefits of the software-defined data centre to storage. By clustering server hard disk and solid state drives (HDDs and SSDs), Virtual SAN creates a flashoptimized, highly resilient shared datastore designed for virtual environments. Based on a hypervisor-converged distributed architecture embedded in the vSphere kernel, Virtual SAN can make optimal data placement and I/O optimizations. Because it sits directly in the I/O data path, the product is able to deliver the highest levels of performance, scalability, and resilience without taxing the CPU with additional overhead. Virtual SAN also differs from other storage products in its policybased approach to storage management. This management architecture enables administrators to specify storage attributes- such as capacity, performance, and availability-in the form of simple policies on a per-VM basis. These policies, governed by service-level agreements (SLAs), dynamically self-tune and load-balance the system so that each virtual machine has the right level of resources. The system can adapt to ongoing changes in workload conditions to ensure that each virtual machine has the storage resources it needs. Virtual SAN distributed architecture leverages enterprise-grade SSDs for high-performance read/write caching and HDDs for costeffective data persistence. Using server-side storage, Virtual SAN delivers unmatched price/performance compared to other Virtual Storage Appliances (VSA) or midrange hybrid arrays in the market today. The Virtual SAN datastore granularly scales up by adding more disks or scales out by adding more hosts, allowing users to configure the system to meet their needs flexibly.
