VSAN is a software-defined storage solution from VMware that provides shared storage for vSphere clusters without requiring external storage arrays. It aggregates local storage resources from ESXi hosts to create a distributed shared storage platform. A VSAN cluster requires a minimum of three hosts, a VSAN network, and local disks on each host that are pooled to create a virtual shared VSAN datastore. VSAN eliminates the need for traditional storage and reduces costs while simplifying management.

• What is vSAN?
• VMware vSAN is a popular storage solution provided by VMware in order to eliminate the requirement of additional
storage containers using local server storage. VSAN stands for virtual storage area network and it basically
abstracts the local level storage of ESXi hosts and make a pool out of it. It is subsequently used as shared storage.
As in case, you are required to use the local storage space, there would not be any requirement to arrange extra
storage boxes in order to store the files, which eventually helps in bringing down the TCO i.e. Total Cost of
Ownership.
• VMware vSAN is a software-defined storage solution that seamlessly integrates with vSphere, transforming your underlying
storage infrastructure.
 It aggregates local storage resources from ESXi hosts to create a distributed shared storage platform.
 vSAN eliminates the need for traditional storage arrays, reducing costs and simplifying management.

VSAN is a software-defined storage solution providing shared storage
for vSphere cluster without using traditional external storage
A VSAN Cluster requires:
• A minimum of three hosts to be part of the vSphere cluster and enabled for
vSAN
• A vSAN network
• Local disks on each host that are pooled to create a virtual shared vsan
datastore

18. VMware VSAN
• Architecture of vSAN
 vSAN architecture consists of three main components:
1. ESXi Hosts: Local storage devices are pooled together to create a distributed storage cluster.
2. vSAN Datastore: Virtual machines are stored and accessed through the vSAN datastore, leveraging the aggregated local
storage.
3. vSAN Cluster: Multiple ESXi hosts form a vSAN cluster, providing increased capacity and performance.

• vSAN Architecture
Modes
• vSAN supports two
architecture modes:
1. Hybrid Mode: Combines
traditional magnetic disks
(HDDs) and flash-based
caching (SSDs) for cost-
effective performance.
2. All-Flash Mode: Utilizes solid-
state drives (SSDs) for optimal
performance and
responsiveness.
