VMware vSAN Reviews

The storage policies allow the administrator to define which VMs have specific storage requirements. For example: Our critical VMs have an increased flash read cache percentage enabled. This improves the overall performance of these machines. The ability to specify policies for every kind of VM in your data center improves storage efficiency, as well as improving performance, redundancy, and so on for specific VMs. With traditional SANs, configuring this was only possible on a LUN level. With vSAN, we can do this on the VM objects themselves.

One of the things that surprised me was the way vSAN handles a disk failure. It auto-rebuilds the vSAN objects when a failure has been detected. (Note: There are two kinds of failures, and this has a different effect on the rebuild timer.) But, in the end, the cluster is self-healing without any user input needed. The only thing that is affected is purely the raw storage that is lost with the drive.

The ease of managing and configuring vSAN. This means that all our VMware administrators are now able to do the daily maintenance and operations. Previously, only a couple of IT administrators were responsible for maintaining our previous storage solution and the complex tasks that came with it.

• The daily maintenance can be high, especially due to the lack of documentation and reporting in vCenter, and only on the vSAN health page.
• If the vSAN cluster can’t self-heal due to an internal error, we can’t repair the vSAN cluster ourselves.
• A case with VMware is always needed to fix the issue, resulting in an increased time to resolve. This can be very time-consuming.
• I would like to see more documentation on the errors, impact, and solutions. This could improve the product knowledge.
• Some essential storage features (deduplication/compression) are only available on all-flash vSAN clusters. These limitations need to be taken into account when sizing and designing your environment.

We have been using this solution for a year.

Keep a close eye on the vSAN HCL. As vSAN is continuously in development, the HCL changes as well and so the HCL gets updates.

When you are planning to upgrade the vSAN version, all other components (ESX version, server firmware, server BIOS) need to be checked to see if they are all on that version’s HCL.

Scalability on vSAN is extremely easy. If the host is compliant with the prerequisites (one SSD and one spinning disk), it will be accepted by the cluster instantaneously. All raw storage will be committed to the vSAN data store and directly available for usage.

In terms of sizing the cluster, as deduplication and compression are only available on all-flash arrays, this can heavily impact the storage capacity of the vSAN cluster.

Since we chose a hybrid-configuration, the lack of deduplication and compression caused a storage growth that exceeded the limits quite rapidly. We had to scale up and address the issue in other ways.

Technical support is good. When encountering issues with vSAN, 99% of the time a VMware support case needs to be opened. All of the standard steps of a support case are run through. In the end, a VMware engineer will solve the issue with you and bring the cluster back to a fully healthy state.

Our previous hyper-converged system broke down due to a power failure. A new system was needed. vSAN was the logical choice, as we are a VMware Partner.

The way VMware integrated the vSAN hyper-converged storage functionalities in their vSphere Kernel is really revolutionary.

It allows the environment to scale out on storage resources when the business needs it. You no longer have to buy those expensive traditional SAN setups scaled for the “future requirements” that you had in mind at the time.

Even an IT administrator with some basic VMware experience would be able to set up vSAN in just a couple of minutes. This is one of the easiest setups I have had in a while.

We had previous solutions, but vSAN was the logical choice.

I would definitely recommend vSAN to others. The old, cumbersome, and traditional storage environments are done and belong to the past. Hyper-converged is the next big thing. It is more cost effective, easier to manage, and scaling up can be done almost on the fly.

I recommend going for an all-flash vSAN setup, if the budget allows it. Some vSAN features like deduplication/compression are only available on an all-flash configuration.

With the falling GB/$, an all-flash is becoming the evident choice. The benefits are there (more features and all-flash performance for all VMs).

our primary use case is storage; hyper-converged solutions for our customers. We develop and design higher availability infrastructure for customers with the vSAN as its base. I'm a consultant and an architect for solutions with the software. My company is a partner with VMware.

High availability is a valuable aspect of this solution.

An integrated backup solution within the vSAN platform would improve the product. Competitors like SimpliVity, UCS, and Cisco Hyperconverged all have a backup feature in their hyper converged infrastructure, it's something that a lot of people use now.

I've been using this solution for four years. 

This solution is super stable. 

This solution is very scalable. However, we've seen some limits within the platform although I believe the latest version may have solved those problems. 

The initial setup is very simple and straightforward. If the setup also involves hardware deployment, the process can take a day or so, but if it's just the vSAN deployment, it can be done in several minutes. I generally carry out the implementation. 

It's important to use someone who is familiar with the solution to carry out the implementation. It's fairly straightforward but if you set it up incorrectly then you'll have issues with your underlying storage. It's worth having a professional service to manage things. 

I rate this solution 10 out of 10. 

We use VMware vSAN to build storage for our virtual machines.

I like the tolerance of VMware vSAN.

The integration could be improved. I would like to see integration with other platforms.

We have been using VMware vSAN in our environment. I have used this solution for more than five years.

VMware vSAN is a stable solution.

It is easy to scale VMware vSAN.

In our organization, we have 100 members.

We may increase our usage in the future. With the company's growth, there are plans to expand in the future. We may require additional members. It's possible that we'll be able to scale this solution more in the future.

We read the manual, which provided us with a thorough explanation. It was sufficient. We use technical support only on rare occasions.

Nutanix is a product that I am familiar with. We were able to use the Nutanix supported trial version.

In Microsoft's system center, both Nutanix and VMware can be easily maintained.

We will not be using the Nutanx system at this time.

Nutanix's integration with other platforms could be improved.

This solution was easily installed by our team.

We have a team of four people to deploy and maintain this solution, including one administrator and one manager.

This solution requires the purchase of a license.

Because of COVID-19's impacts, we looked for a different IT system that would match our budget.

I would recommend this solution to others.

I would rate VMware vSAN an eight out of ten.

Virtual Desktop.

Easy to use.

Horizon VDI

Raw disk and block disk.

Easy to configure vSAN. I have configured with in 30 minutes. IOPS is comparatively best to run VDI solution. Policy based profiling is a best advantage. Recently VMware launched iscsi support for vSAN is an added advantage.

2 months back we started using this.

Yes. MTU settings will be vary depending upon network switch.

No.

No.

I haven't contacted any technical support.

Earlier customer has used Netapp and EMC storages, In that they faced issues on stability and scalablity.

Its straightforward.

I have deployed this solution to end customer.

Not yet calculated

Its reasonable, compare with other storage vendors

No

Deduplication and compression: Software-based deduplication and compression optimizes the all-flash storage capacity.

Compared to other vendors, vSAN is compatible with more expensive hardware, and Nutanix is available on multiple hardware platforms, like Supermicro, Dell and Lenovo.

I have used it for two months; just for test purposes.

We have not encountered any stability issues.

We have not encountered any scalability issues.

Technical support is 10/10.

We did not previously use a different solution.

Initial setup was straightforward; I had the KB from VMware to help me deploy the solution.

Before choosing this product, we evaluated OpenStack Object Storage.

It is a good solution for customers that are looking for performance, storage efficiency, and scalability.

Snapshot: You know, that is amazing.

In our routine work, there is repeatable testing and validation. With the snapshot feature, we are able to keep our system in a specific status, including application parameters and network settings.

That has totally reduced our valuable time.

Currently, the work style of our organization has changed; when we get new projects, we can rapidly handle them.

If vSAN developed a "unified system" (that can support block + file + object), it would help users a lot in facing hybrid cloud environments.

I would prefer to use a complete and deep dashboard so I can give a supervisor a way to easily monitor the status of all drives and pool tiers. I think that would be a powerful feature for the future.

I have used it for two years.

Stability is great; however, you have to notify your counterparts if the system breaks down. :-D

Many popular SDS products can support up to 1000 nodes. This is an area where I hope vSAN is improved.

Hmmm, the level of technical support depends on the engineer who supports you when you contact the call center.

Traditional storage is scale-up type, which means there are a lot of supplier limitations and it costs too much.

Why not break though this situation? Now, flash is getting cheaper and bigger. With the changes mentioned, I think it will just stimulate SDS.

Initial setup was very simple for me. It is easy to set up if you get used to using vCenter.

SDS is going to be popular and common. If vSAN wants to remain #1 in the market, offering more discounts or something to attract customers is inevitable.

Currently, our environment is running VMware; therefore, we can consider using original distributed storage that connects directly to the kernel. That would reduce latency and data transfer loss.

It is easy to use and rapidly build up.

Simple to set up, manage, and integrate it with tools you’re already familiar (vCenter, vClient) with.

It also gives us a policy-based storage on a per-VM level.

Also if you can apply redundancies to machines, they’re all different.

• All built within hypervisor
• Easily stood up with hardware you already have
• Truly virtualized storage
• Get rid of all hardware, and you get a much smaller footprint
• Nodes can be in different datacenter, and so can stretch cluster

• Good job integrating with vRealize, vCOPS, etc.
• Needs complete integration with vRealize for GUI for drill down analysis
• Would be nice to see features like dedupe because it wastes a lot of mass when striping across multiple nodes and vSphere hosts.

Some difficulty finding compatible hardware, but if you follow the HCL provided by VMware. and make sure you're buying the correct nodes, storage devices, and SSD’s that are all supported, then it’s a stable product. Even if you have problems, it's still only one phonecall.

It supports up to 64 nodes so huge scalability.

As a VMware customer for many years, sometimes it takes a few calls, but they have some brilliant people who can solve difficult technical problems.

• Setup just a few clicks after hardware all connected, “pretty stupid easy”.
• Customers can test and validate without going out and buying vSAN ready nodes.

It loses points because it lacks lots of performance and deduplication abilities that competitors have.
