VMware Announces General Availability of Virtual SAN

On March 12, 2014, VMware announced the general availability of VMware Virtual SAN software, VMware’s first Software-Defined Storage product that changes the way that storage has been operated to date. Designed to deliver efficiency and resiliency, VMware Virtual SAN (vSAN) is simple, hypervisor-converged storage that introduces a new high performance storage tier optimized for virtual environments.

Delivering high-performance storage for virtual machines, VMware vSAN is ideal for use in virtual environments such as Virtual Desktop Infrastructure (VDI), disaster recovery, and test/development. Features of VMware Virtual SAN include:

  • Hypervisor-converged architecture - Embedded within the VMware vSphere kernel, vSAN delivers the most efficient data path while reducing resource use, resulting in a consumption of less than 10 percent of CPU resources. 
  • High performance with elastic and linear scalability – By using flash to deliver performance acceleration through read/write caching, Virtual SAN delivers a flexible approach to provisioning, performance, and capacity. This allows users to linearly scale clusters on demand by adding nodes to a cluster or disks to individual nodes. 
  • Storage Policy Based Management – While shifting the management model for storage from the device to the application, a single VMware Virtual SAN datastore can provide differentiated service levels that are based on individual VM policies. Here, there are no difficult configuration procedures, over provisioning is avoided, and policies can easily be changed. Automated provisioning and management improves the ability to meet Service Level Agreements (SLAs). 
  • Integration with the VMware stack – Enabled by two clicks in VMware vSphere Web Client, VMware Virtual SAN is simple to configure and deploy. This allows users to access data services such as cloning, replication, snapshots, and backup. 

Through less Capital Expenditures (CapEx) and Operating Expenditures (OpEx), Virtual SAN provides users with a reduced Total Cost of Ownership (TCO). The software uses server side hardware economics by pooling internal magnetic disks and flash devices from industry standard x86 servers. This allows users to skip upfront costs, adding disks or nodes to their cluster on an as-needed basis. Automation eliminates many manual processes while easing management, capacity planning and storage configuration.

VMware Virtual SAN can be deployed on a wide range of servers and is interoperable with VMware vCloud Automation Center, VMware Horizon View 5.3.1, VMware vCenter Operations Management Suite, and VMware vCenter Site Recovery Manager.
