VMware vSAN Reviews

• Performance
• High Availability

It's relatively low-cost for a high-performance solution. By using VSAN, we've been able to simplify our infrastructure considerably.

VSAN currently has no data deduplication, and having such a feature would both be an improvement and provide a feature that Nutanix has.

N/A

The stability is very good.

Having now deployed it, it's actually difficult to have any downtime or to even lose data.

Considering I've only done one VSAN cluster, I'd say that the scalability is good. We haven't yet tried to add more clusters.

Our company currently has 20,000 users and we expect further growth, so we'll likely have to scale down the road. That said, I don't anticipate really any issues with scalability at that point.

N/A

Tech support is very good as they're responsive.

We have the Technical Account Manager service, which is very helpful.

N/A

Setup was not complex at all, was very straightforward, and was easily implemented by everyone on the team.

We implemented it with out in-house team.

We chose VSAN based on a POC. We looked at Nutanix, but VSAN was more robust for our needs and less expensive.

We normally use Gartner as a source, as well as some testing and a POC. The POC was the most important criteria, so my advice would be to do that before committing the resources.

VMware vSAN is a storage virtualization software.

What I found most valuable in this software is its storage management feature.

I don't recall an area for improvement in VMware vSAN, because it's a concept, a brand, and a product. If the concept doesn't change, we can't improve this software that much, but VMware can probably make the monitoring feature much better.

I've been dealing with VMware vSAN for eight years now.

VMware vSAN is a stable software.

VMware vSAN is a scalable software.

Clients have to pay for VMware vSAN licensing based on the number of CPUs. Whether it'll be a yearly or a monthly subscription, you have to check with the vendor, because you can buy it for one year, two years, or three years. The purchases would be lifetime or perpetual, but you need to have support, e.g. the support is negotiated from one, two, three, or four years.

VMware vSAN is my main product, and I'm an integrator for it.

The current version we're using is the VMware vSAN 6.2 version.

The setup of VMware vSAN is the same setup as the ReadyNodes, because the ReadyNodes are built on top of vSAN technology. As for how long it takes to deploy, it depends on the number of hosts you're deploying.

We have six clients currently using this software.

For deployment and maintenance of VMware vSAN, we have two technical staff who are in charge: one for setting up the network, and the other one for setting up the physical environment.

I'm recommending this software to others who want to start using it. You can install it on any kind of ReadyNodes.

I'm rating VMware vSAN nine out of ten.

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. 

The main use case for VMware vSAN is auxiliary services, such as Windows, Linux, and not a specific server, but mixed loads.

We were able to replace lots of negative servers and replace them with VMware.

VMware vSAN is compatible with the legacy hypervisor solutions and most of the features are good.

I have been using VMware vSAN for approximately five years.

The solution is stable.

The scalability of the solution is good. The node cluster they are using has been enough for them.

we have approximately 1,000 users using this solution.

The technical support, it's not satisfactory. Whenever we raise a ticket it takes a lot of time to have an engineer get involved sometimes, or we receive a less experienced engineer. We then have to repeat the situation to the next engineer which all takes time.

The setup is not complicated. The deployment of VMware vSAN with VxRail can be completed in three to four hours, for one cluster out of the physical setup. The physical setup could take approximately one day. After that, deployment is very easy to complete.

We have four people that do the deployment and physical setup of the solution.

The price of the solution package depends on the nodes and other factors. The cost some of our customers paid was $500,000. The licensing cost for the components is very good.

My customers were comfortable with VMware and then they decided to use VMware instead of another solution.

My advice is if someone is interested in VMware vSAN it is a good solution. It is stable, supportive, and compatible with many solutions. VMware vSAN is the best.

Customers have to consider when choosing VMware to receive a lot of features, such as replication backup, and if they went with another solution it would be more expensive.

I rate VMware vSAN a nine out of ten.

We primarily use the solution for 95% of our hyper-converged infrastructure deployments.

The solution is very stable.

The installation is very easy. The deployment is fast and only takes, at a maximum, 2 days.

The scaling could be a bit better.

The monitoring capabilities could be improved. It would be ideal if clients didn't need to monitor the solution on a daily basis.

I've been using the solution for about five years at this point. It's been a while. 

The solution is quite stable. There are no bugs or glitches. It doesn't crash or freeze. the performance has been good.

We do have plans to continue to work with the solution. However, we do not use the solution ourselves. We are integrators. Deployments and their sizes depend on the clients.

We have about 60 to 100 clients that use the solution.

The initial setup is not overly complex or difficult. It's very straightforward and very simple to set up.

It took us about two days to deploy the product.

We had about five people who handled the deployment.

We did not need the help of a consultant or integrator. We are integrators ourselves. We were able to handle everything in-house with our own team.

I can't speak to the licensing arrangements or specific costs of the product.

We are integrators and a partner to the vendor.

We are working with the latest version of the solution at this time.

I'd rate the solution at an eight out of ten. Our clients are pretty happy with it overall.

I'd recommend it to other users and companies. 

We are service providers. 

vSan is a system with defined storage, it doesn't work on a public cloud. It works and is built in your private cloud.

The most valuable features are Erasure Coding, Deduplication, and Compression, and the advancement in stretching regarding replication.

They should provide Deduplication and Compression over the hybrid drives. The Deduplication and Compression are locally only on all flash drives.

When you compare with Nutanix, you will find the performance in the Deduplication and Compression is over hybrid and on the flash drives. This feature is needed in vSan.

I have been working with VMware vSan for five years.

We are using the latest version.

VMware vSAN is very stable.

It's scalable up to 96 nodes. We have over 500 users in our company who are using this solution.

VMware technical support is remarkable.

We did not work with a similar software preciously. We were working with traditional solutions such as storage, and servers, but not software-defined storage like vSAN.

The vSAN is very easy to deploy.

To deploy a full cluster in a data center, can take four hours.

We are all engineers. We don't need a team to maintain this solution, as everyone services themselves.

The price could be lower. vSAN has many versions with standard and advanced including Enterprise and Enterprise Plus. Regarding the Enterprise and the Advanced, it could be lower.

I would rate this solution an eight out of ten.

The most valuable features of vSAN are:

• Instead of having a separate SAN storage, VMware uses all the local storage of the servers to combine its virtualized storage.
• Hyper-converged, an infrastructure system that is software defined: It integrates the computing, storage, and networking into a single platform.
• vMotion: This is one of the best features in this setup. From the name itself, vMotion allows migration without downtime. Others call it live migration. Planed server downtime is dramatically reduced by this feature.
• High availability (HA): This is my favorite. vSAN requires you to have at least three servers. Those three servers are being combined into one platform; that's vSAN. HA actually works during server failure. The server will automatically distribute to other servers in the environment.
• SSD tiering: You can combine a magnetic disk and solid-state drives to have a hybrid drive. This is actually fast because the SSD will be used for caching and the magnetic disk will store the actual data.

The most valuable feature of ESXi is that it is free. I strongly recommend this for those who have a huge development environment. ESXi is the best no-cost virtualization platform in the market right now, where you can consolidate your server into one platform.

The virtualization itself really helped me as a network and system administrator with a lot of servers to maintain. That's a pain. A virtualized environment is really easy to manage. Almost everything is in one dashboard. This really gives us more time in our research and innovation, and less time for maintenance or upgrades.

The minimal downtime alone is a winning blow for both the management and the ITs. Unexpected downtime is inevitable. It's been part any organization. Addressing that pitfall really gives an edge (from a business perspective).

Long-term savings in both buying more server in the future and absolutely the power consumption, not to mention the data center space it released or freed.

The mobility, flexibility, and scalability are really amazing and astonishing features.

I would like to see lowered cost. vSAN is very expensive.

I have used vSAN for two or three months. ESXi has been with us for around three years.

We are using vSAN 6.2, ESXi 5.5 and 6.0, and vSphere 6.0.

We have not had any stability issues so far.

Scalability is one of its strengths.

We haven't called technical support so far. But the web (Google) actually has plenty of good articles and forums and discussions. The website has also one of the best FAQ and DIY sections; 90% level of technical support.

We did not have a chance to try other virtualization platforms because the first one we tried really gave us a strong enough reason to stay loyal.

Initial setup was straightforward. You'll only have what you want.

Hopefully, over the next few years the pricing will be dramatically lower.

We are biased from the start to use VMware products only.

Study and evaluate your current setup. Conduct a case study to see if the advantages really outweigh the disadvantages. Virtualization really is the future. Especially here in my corner, almost all or most of the data centers are still in bare-metal setup. Because of the big price (CAPEX), most of the time, management will disapprove this project. But, if you help them see the big picture, I'm sure they are going to promote you for providing this project.

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.
