What is vSAN in simple terms?

What is vSAN in simple terms?

VMware vSAN is a software defined storage solution from VMware to eliminate the need of the additional storage boxes using the local server storage. In simple words – vSAN abstracts the local storage of ESXi hosts and makes a pool of it to be used as a shared storage which is very much optimized.

What is vSAN and how it works?

VMware vSAN uses a software-defined approach that creates shared storage for virtual machines. It virtualizes the local physical storage resources of ESXi hosts and turns them into pools of storage that can be divided and assigned to virtual machines and applications according to their quality-of-service requirements.

What is the purpose of vSAN?

Storage Virtualization Software vSAN. Reduce storage cost and complexity with VMware vSAN, an enterprise-class storage virtualization software that provides the easiest path to HCI and hybrid cloud.

What do you mean by vSAN in cloud computing?

virtual storage area network
A virtual storage area network (VSAN) is a logical partition in a physical storage area network (SAN). VSANs enable traffic to be isolated within specific portions of a storage area network, so if a problem occurs in one logical partition, it can be handled with a minimum of disruption to the rest of the network.

How do you use vSAN?


  1. Navigate to an existing cluster in the vSphere Web Client.
  2. Click the Configure tab.
  3. Under vSAN, select General and click the Configure button.
  4. Select vSAN capabilities.
  5. Click Next.
  6. On the Network validation page, check the settings for vSAN VMkernel adapters, and click Next.

What is vSAN and its benefits?

VMWare vSAN is a software-defined storage product that is used in collaboration with VMware ESXi hypervisor. VMWare vSAN reduces the cost and complexity that exists in traditional storage solutions by offering the capability of using policies and rules to manage storage.

How do I set up vSAN?

Is vSAN any good?

VMware vSAN is one of our storage tools and we use it for tier 2 storage. It is great in the scalability but not that great for high performance. It is a great alternative for a homogenous environment with no high IOPS utilisation. Sadly, it’s too expensive.

Is vSAN a protocol?

As vSAN only communicates with vSphere virtual machines, there’s really no need for a standard storage protocol. vSAN uses a proprietary protocol within the cluster that’s more efficient than the familiar choices.

What is the difference between vSAN and VxRail?

One major difference between looking at a VxRail appliance vs. vSAN Ready Node running on Dell hardware is that Dell will fully certify the system hardware and also provide a single bundle, single-click installation and/or upgrade capability, including all necessary firmware.

How do I know my vSAN configuration?


  1. Navigate to the vSAN cluster in the vSphere Web Client.
  2. Click the Configuration tab.
  3. Under vSAN, click Configuration Assist to review the vSAN configuration categories.
  4. Select an individual configuration check and review the detailed information at the bottom of the page.

What is a difference between San and VSAN?

SAN is a storage area network. While (VSAN) is a virtual storage area network which is a logical partition in a storage area network. VSANs allow traffic to be isolated within specific portions of a storage area network. Upvote (3)

How to configure VSAN?

Login to vSphere Web Client. Choose the cluster on which you want to configure vSAN.

  • vSAN Configuration wizard will open. Choose the services which you want to configure with vSAN.
  • Here you will see the Network validation results which will show the vSAN VMkernel status.
  • This is the important part of the vSAN Configuration.
  • How does VSAN works?

    VSAN is developed by VMware and used in a VMware vSphere cluster to create a distributed, shared data store. The storage requirement is provided by user like performance and availability, for virtual machines ( VMs) on a VMware vSAN cluster. vSAN ensures that these policies are properly administered and maintained.

    What is vSphere VSAN?

    VMware vSAN Overview. vSAN is the Software Defined Storage solution from VMware which is tightly integrated into VMware vSphere. Together with ESXi and the Software Defined Networking solution VMware NSX , VMware provides you a Software Defined Data Center (SDDC) solution.
