Is VMware vSAN any good?

Is VMware 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.

What is the difference between vSAN and vSphere?

VMware vSAN uses object-based storage architecture where each object represents a block of data within the underlying Virtual Machine (VM). A vSphere cluster is the primary management unit for the VMware vSAN. You can create a vSphere cluster as either an all-flash cluster or hybrid vSAN.

What is vSAN used for?

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 three great use cases for vSAN?

Review the five most common use cases seen within the Virtual SAN install base, including production, management cluster, ROBO deployment, DMZ/isolation, and development platforms.

Does vSAN need vCenter?

vSAN & vCenter are totally independent of each other and vSAN will continue to run even without vCenter. Assuming you had a vSAN cluster all setup and configured today, running production workload. Someone then accidentally powered off the vCenter server, technically, nothing is going to happen to the vSAN environment.

What is vCenter vSAN?

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.

Does vSAN need vSphere?

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. Only vCenter Server is required to configure and manage a vSAN cluster.

Will vSAN work if vCenter is down?

A commonly asked question is “What happens to vSAN when vCenter Server is offline?” The answer is simple: nothing. vSAN continues to operate normally and virtual machines continue to run. A new vCenter Server can be deployed and the existing vSAN hosts can be added to the new vCenter Server—all without VM downtime.

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 require license?

vSAN Standard, Advanced, Enterprise and Enterprise Plus licenses are per-CPU (socket) licenses . All hosts in the cluster must be licensed . All-flash vSAN configurations are supported with the Standard license . Deduplication, compression and erasure coding require Advanced, Enterprise or Enterprise Plus licenses .

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 require 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.
