VMware Virtual SAN is radically simple, hypervisor-converged storage designed and optimized for vSphere virtual infrastructure.
Radically Simple Storage for VMs
- Single-pane-of-glass management with vSphere: vSphere Web Client-based management eliminates the need for training on specialized storage interfaces and tools. Provisioning storage for a virtual machine is now as easy as two clicks.
- VM-centric policy-based control and automation: Storage service levels are assigned to individual virtual machines or virtual disks in the form of storage policies; storage resources are provisioned based on these policies. You can adjust storage policies on the fly if applications requirements change. No LUNs or RAID configurations are necessary.
- Self-tuning: Automatically rebuild and rebalance storage to align with the storage service levels assigned to each virtual machine in the cluster. No manual adjustments are needed.
- Built-in failure tolerance: Data is not lost due to disk, host, network or even rack failures thanks to distributed RAID and cache mirroring. Maximize resiliency by defining availability on a per-VM basis. You can specify how many host, network, disk or rack failures to tolerate in a Virtual SAN cluster when setting the storage policy for each VM.
- Interoperable with VMware stack: Virtual SAN is fully integrated with core vSphere features such as High Availability, Distributed Resource Scheduler (DRS) and vMotion. Leverage vSphere Snapshots, vSphere Data Protection, and vSphere Replication for data protection, backup, rapid cloning and data transfer across clusters or sites; VMware vCenter Site Recovery Manager for automated orchestration for DR purposes; VMware vRealize Automation for intelligent and simple resource management; and VMware Horizon (with View) for virtual desktop environments.
Consistent High Performance with Elastic Scalability
- Unique architecture built within the hypervisor: Virtual SAN is embedded into the vSphere kernel and thus provides the shortest I/O data path, optimizing performance with the least impact on CPU.
- Server-side caching: VM performance is improved and storage latencies are minimized by caching and accelerating read/write disk I/O traffic, leveraging enterprise-grade server-side flash.
- All-Flash architecture with SSD data persistence: An all-flash architecture, flash-based caching and data persistence on SSD devices provide extremely high performance with consistent low latency.
- Granular non-disruptive scale-up and scale-out: Virtual SAN provides elastic, on-the-fly scaling in both hybrid and all-flash architectures. In hybrid architecture, scale both capacity and performance at the same time by adding a new host to the cluster (scale-out). Or, scale capacity and performance independently by adding disks (HDDs for capacity and SSDs for performance) to an existing host (scale-up). Similarly, in all-flash architecture, you can add either hosts or SSDs to scale performance and/or capacity.
Lower TCO by up to 50%
- Lower storage CapEx: A distributed, hypervisor-converged storage architecture leverages industry-standard hardware components and lowers storage CapEx by as much as 50 percent.
- Lower OpEx—no specialized skill set needed: If you know vSphere, you know Virtual SAN. Embedded in the hypervisor, it can be managed end-to-end from the vSphere Web Client. It integrates with the VMware stack and core vSphere features such as High Availability, DRS and vMotion, simplifying management of storage for VMs in the vSphere virtual infrastructure.
- Budget-friendly scaling: Reduce the need for large upfront investments with granular, controlled scaling. Add additional hosts, disks or flash as needed and avoid overprovisioning or overpaying for future capacity and performance needs.
