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: Virtual SAN is managed from the vSphere Web Client so there is no 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 by using VMware's solution for app-centric storage automation, Storage Policy-Based Management. Virtual SAN provisions storage resources based on these policies. Storage policies can be adjusted on the fly if application needs change. No LUNs or RAID configurations necessary.
- Self-tuning: Virtual SAN automatically rebuilds and rebalances storage to align with the storage service levels assigned to each virtual machine in the cluster. No manual adjustments needed.
- Built-in failure tolerance: Data is not lost due to disk, host, network or even rack failures because Virtual SAN leverages distributed RAID and cache mirroring. Resiliency is maximized 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, DRS and vMotion. Virtual SAN also leverages 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 increased intelligent and simple resource management, and VMware Horizon (with View) for simple and fast storage for virtual desktop environments.
High Consistent 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 accelerating read/write disk I/O traffic, leveraging enterprise-grade server-side flash.
- All-Flash architecture with SSD data persistence: In Virtual SAN All-Flash architecture, flash-based caching and data persistence on SSD devices provides 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, both capacity and performance can be scaled at the same time by adding a new host to the cluster (scale-out) or capacity and performance can be scaled independently by adding disks (HDDs for capacity and SSDs for performance) to an existing host (scale-up). Similarly in all-flash architecture either hosts or SSDs can be added for scaling performance and/or capacity.
Lower TCO by up to 50%
- Lower storage CapEx: Virtual SAN provides a distributed, hypervisor-converged storage architecture that can leverage industry-standard hardware components and lower storage capex by as much as 50%.
- Lower OpEx: no specialized skillset needed: If you know vSphere, you know Virtual SAN. Virtual SAN is embedded in the hypervisor and 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, vMotion etc., simplifying management of storage for VMs in the vSphere virtual infrastructure.
- Budget-friendly scaling: Virtual SAN reduces the need for large upfront investments by providing granular, controlled scaling. Add additional hosts, disks or flash as needed: no need to overprovision or overpay for future capacity and performance needs.
