Why vCloud Tech?vSAN integrates seamlessly with VMware vSphere as a distributed layer within the ESXi hypervisor

VMware vSAN, a software-defined enterprise storage solution, supports hyper-converged infrastructure systems (HCI). vSAN aggregates direct-attached or local data storage devices to create a single storage pool that all hosts share within a vSAN cluster. A hybrid vSAN cluster employs flash devices to store the cache tier and magnetic drives to store the capacity tier. A flash-optimized, resilient vSAN collection that uses flash devices both for the cache tier and the capacity tier. This architecture creates a flash-optimized, resilient shared datastore suitable for the software-defined storage centre (SDDC). Storage Policy-Based Management (SPBM) simplifies storage configuration and eliminates external shared storage. Using a virtual machine (VM) and storage policies, you can set storage requirements and capabilities. 

vSAN is a hyper-converged product from VMware. It pools direct-attached storage devices within a VMware vSphere cluster to create a shared data store. The user defines the storage requirements for virtual machines (VMs), such as availability and performance. vSAN manages and maintains these policies. The vSphere Web Client manages cluster administration and storage policy implementation. vSAN supports hybrid and all-flash configurations with a two-tier architecture. Both structures have a caching and capacity tier. A caching level contains at least one flash device per host. The capacity tier comprises one flash device (all-flash) and one magnetic disk (hybrid) per host. vSAN combines all of the storage resources on a host into a single shared, high-performance data store that all hosts can use in the cluster.

VMWare vSAN features depend on the type of license but includes the following:

  • Storage policy-based management (SPBM) allows for the automated control of storage profiles.
  • Software-defined data encryption is available to prevent unauthorized access to data at rest.
  • A cluster can contain 2 to 64 nodes.
  • Stretched clusters allow more than one¬†VMware storage virtualization¬†host to be used in one setup, providing greater security and availability.
  • Clusters support deduplication (eliminating duplicate copies of the same data), compression, and erasure code (protecting data by breaking it into sectors), which ensures efficient storage management and security.
  • Supports storage quality of service (QoS), which allows administrators to limit the input-output operations per second (IOPS) that specific VMs consumes.

Improve IT productivity by centralized visibility and alerts to your vSAN infrastructure:

  • Transform HCI seamlessly:¬†Our secure hyper-converged solution integrates with leading public cloud providers and your hypervisor to allow you to leverage your existing tools for virtualization storage.
  • Multi-Cloud HCI Platform:¬†Using a single cloud console, you can improve IT productivity by centralized visibility and alerts to your vSAN infrastructure. Also, manage virtual machine and container-based apps seamlessly with VMware Tanzu integration.
  • Lower costs:¬†You can get a better price per performance using the most recent¬†VMware virtual storage¬†technology on an industry-standard server.
  • Flexible deployment:¬†With the largest ecosystem in the industry, you can use HCI wherever you are, which includes 18 OEM server vendors and native services with top public clouds such as AWS, Azure and Google Cloud, Oracle Cloud, and IBM Cloud.
  • Scale without Compromise:¬†VMware HCI Mesh allows you to scale computing and storage quickly and flexibly to meet your application requirements.
  • Operation simplified:¬†Easy deployment of new infrastructure and applications with minimal training.
  • Developer-Ready Infrastructure:¬†You will get the self-service capabilities developers need to create apps on a large scale. Also, the governance IT admins must have to manage containers and VMs.


  • Maximize deployment flexibility and future-proof HCI:¬†You can use vSphere and¬†vSAN¬†to manage storage and compute resources from one platform. Our integrated solution provides the fastest path to future-ready HCI/hybrid cloud systems. It delivers faster operations, lower costs and better business agility.

  • Industry-leading flexibility:¬†Run HCI on certified solutions from 18 OEM server vendors and leverage native services on leading public clouds.
  • Multi-cloud capabilities:¬†End-to-end intrinsic security ensures consistent operations from edge to core to cloud.
  • Centralized apps:¬†Manage traditional and modern apps on the same platform.


A vSAN cluster requires at least two physical hosts with dedicated local storage devices and a shared witness. For more information, see his VMware Compatibility Guide for Systems/Servers and his VMware Compatibility Guide for vSAN.

Yes, subject to normal export controls and sanctions restrictions.

The vSAN Express storage architecture is an optional next-generation architecture integrated with vSAN to provide the highest performance and efficiency from NVMe storage devices.

  • Optimized Performance:¬†Maximize the performance of NVM-based TLC devices without sacrificing space efficiency.
  • Highest Efficiency:¬†Provides higher data compression and space savings for a lower total cost of ownership.
  • Improved resilience:¬†Increase availability to meet higher SLA requirements.

Yes. vSphere can access and use traditional data stores with vSAN and vSphere Virtual Volumes. In most cases, vSphere Storage vMotion can migrate VMs between these datastore types. This allows for easy migration of existing workloads as storage solutions are maintained or retired.
