What are three great use cases for vSAN?

STO4650 – Five Common Customer Use Cases for Virtual SAN

What is the use of vSAN?

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 are the advantages of vSAN?

The touted benefits of VSAN include: Performance, since the local server can access data at full speed and low latency. Lower infrastructure cost, since there are no networked storage appliances. High scalability -- simply put, add more servers and get more storage.

Which of these features are characteristics of vSAN?

vSAN integrates with vSphere data management features traditionally used with VMFS and NFS storage. These features include snapshots, linked clones, and vSphere Replication. vSAN works with VM storage policies to support a VM-centric approach to storage management.

What advantages does vSAN offer compared to a conventional SAN?

Essentially, it boosts the capabilities of a traditional SAN through virtualization. A vSAN is an Ethernet-based block-I/O platform. It simplifies administrative work and lowers costs compared to a nonvirtual SAN but can be difficult to scale.

What is a SAN vs vSAN?

Differences Between SAN and vSAN

With a traditional SAN, storage administrators are required to pre-allocate storage on different systems, while vSAN automatically converts local storage resources into a single storage pool.

Does vSAN need vCenter?

vCenter Server is required to configure and manage a vSAN cluster. There is no need to install additional software or deploy “storage controller virtual appliances” to every host in the cluster as commonly found in other hyper-converged infrastructure (HCI) solutions.

Does vSAN need vSphere?

vSphere licenses are required on the vSAN cluster to maintain a unified HCI management control plane. Note that the compute clusters require vSphere licenses but do not require vSAN licenses.

What is vSAN stand for?

virtual storage area network (VSAN)

What is vSAN in Vcenter?

VMware vSAN (formerly Virtual SAN) is a hyper-converged, software-defined storage (SDS) product developed by VMware that pools together direct-attached storage devices across a VMware vSphere cluster to create a distributed, shared data store.

Is vSAN a VMFS?

VSAN 5.5 was based on a modified version of VMware Virtual Machine File System (VMFS); VSAN 6.0 gets its own file system, cleverly called VSAN file system. This new file system supports "instant clones" and more efficient snapshots.

How do I configure vSAN?

Procedure

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.

Is vSAN a hypervisor?

vSAN is integrated with the VMware vSphere Hypervisor, so there's no need to install additional software or deploy storage controller virtual appliances to every host in the cluster, as is often the case.

What is vSAN for desktop?

vSAN is enterprise-class, storage virtualization software that allows you to manage compute and storage with a single platform. With vSAN, you can reduce the cost and complexity of traditional storage and take the easiest path to hyperconverged infrastructure and hybrid cloud.

Is vSAN a cloud?

Cloud native storage in vSphere and vSAN allows you to effectively deploy and manage data and storage for modern applications.

How many disks does vSAN have?

At most a vSAN host can have 5 disk groups, each containing up to 7 capacity devices, resulting in a maximum of 35 capacity devices for each host.

How do I apply for a vSAN license?

Procedure

1. Navigate to your vSAN cluster.
2. Click the Configure tab.
3. Under Licensing, select vSAN Cluster.
4. Click Assign License.
5. Select an existing license and click OK.

Is vSAN hyper-converged?

vSAN is VMware's software-defined storage solution for hyperconverged infrastructure. vSAN is natively integrated with VMware vSphere, which manages compute resources, including storage. This means you can access and use traditional datastores along with hyperconverged storage—all in the same cluster.

Does vSAN use NFS?

vSAN File Service is a layer that sits on top of vSAN to provide file shares. It currently supports SMB, NFSv3, and NFSv4.

Does vSAN use iSCSI?

vSAN stretched cluster is supported with iSCSI configuration.

How many hosts do you need for vSAN?

A standard vSAN cluster must contain a minimum of three hosts that contribute capacity to the cluster. A two host vSAN cluster consists of two data hosts and an external witness host.

What is uplink port in VMWare?

Uplink ports are ports associated with physical adapters, provid- ing a connection between a virtual network and a physical network. Physical adapters connect to uplink ports when they are initialized by a device driver or when the teaming policies for virtual switches are reconfigured.

Can vSAN use external storage?

When you use vSAN Direct in the vSphere with Tanzu environment, you can use external shared storage to store management internal VMs and other metadata.

Is vSAN object based storage?

Object-Based Storage

vSAN stores and manages data in the form of flexible data containers called objects. An object is a logical volume that has its data and metadata distributed across the cluster. For example, every VMDK is an object, as is every snapshot.
