VMware vSAN Reviews

I like how it simplifies storage management by converging compute and storage into a single platform. Instead of managing storage arrays, storage resources are aggregated directly from ESXi hosts, which reduces the infrastructure complexity and operational costs. It also, the combination of performance, simplicity, and operational visibility. From the support standpoint, it provides excellent visibility into the health of the storage.

One limitation is that it is tightly coupled to the VMware Ecosystem. Organizations that operate heterogeneous environments or want greater flexibility in their infrastructure choices may find that this increases vendor dependency.

It solves several challenges associated with traditional storage infrastructure. Historically, organizations had to manage separate storage arrays, storage networks, and visualization platforms, which increased complexity, operational overhead, and troubleshooting effort. vSAN consolidates storage directly into the vSphere environment, allowing compute and storage resources to be managed as a simple platform.

Ease of use, vSAN works on different hardware.

There is no particular area I dislike about vSAN.

Disaggregated storage. Usually you don't need to be a full blown storage administrator.

Flexible storage expansion allows me to ad more storage . It offers high performance, user friendly support

You must stick to VMware’s Hardware Compatibility List

vSAN is offering Scalability storage solution with great user experience.

Little overhead as it is already available on the server.

Readily available on the hosts as opposed to accessing legacy SAN.

Downside is having to evacuate during maintenance.

It's more granular & efficient than creating LUNs like in the past. With vSAN your datastore is easier to manage.

Strict requirements if upgrading to vSAN ESA, you need vsan ready nodes which are NVMe-only, if you have SAS disks then you need to use the OSA architecture.

It has allowed us to use local storage from our ESXi nodes to build our datastore.

It solved our IOPS issues we had with traditional SAN.

vSAN make it easier to configure and maintain storage. Lessening our footprint in the data center by eliminating the need for external storage like NAS or SAN.

I find it difficult to understand what RAID configurations are in use and for what files

Consolidating compute and storage. Shrinking data center footprint.

Everything is simpler and just works. Storage is optimized

The gui is a little complex the first timw you start using it

No problems yet

The flexibility to integrate with whole ecosystem

Nothing in specific. It's a great product

Virtualization of Storage.

Compression and deduplication

Scalability

Disk groups and hybrid model with osamodel

Locally attached storage and scalability benefits you.

convenience is the best part about vSAN. Single pane of glass for managing storage policies

vSAN is difficult to troubleshoot because of how complex it is

Keeps our datacenter foot print smaller since we don't need a separate storage solutions.
