What are the requirements for vSAN?

What are the requirements for vSAN?

VSAN Requirements:

• Minimum of 3 ESXi 6.0 host that contribute storage.
• At least one SSD and one Hard Disk per host.
• Hosts need I/O controller supporting Pass Through or RAID 0 (prefer them to be on the VSAN Hardware Compatibility List)
• VMkernel port configured for VSAN traffic.

Do you need SSD for vSAN?

Each vSphere host in the cluster that contributes its local storage to VSAN must have at least one HDD and at least one SSD.

How is vSAN capacity calculated?

Use this formula to determine the raw capacity of a vSAN datastore. Multiply the total number of disk groups in the cluster by the size of the capacity devices in those disk groups. Subtract the overhead required by the vSAN on-disk format.

What is the storage included in vSAN?

VMware vSAN uses object-based storage architecture where each object represents a block of data within the underlying Virtual Machine (VM). Objects that constitute the vSAN datastore include VM Home (which contains the VM configuration files), VM swaps, Virtual disks (VMDKs), and Delta disk (snapshot), among others.

Do you need vCenter for vSAN?

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.

How many hosts are required for vSAN?

3 hosts
For a standard vSAN cluster, a minimum of 3 hosts is required to configure file services.

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.

Does vSAN require vSphere license?

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 RAID does vSAN use?

Yes that’s correct – vSAN does not use hardware RAID, instead the data is protected at the software layer. vSAN uses a concept of disk groups with a minimum of one disk group required per host. A disk group can contain up to seven capacity devices and one cache device.
