VMware vSAN Reviews

Our customers use the vSAN solution for many use cases. The first one is the installations for the branch office or some production use case where they have a small environment, but they need higher availability. The other use case is inside the data center where we installed a big data center solution for virtualization with VMware.

Most of the customers are using the latest version, but I have also done some vSAN installations with version 6.7.

It is easy to use. It is easy to implement for us, and it is also easy to maintain for the customers. It is not necessary to buy some extra devices and talk with other vendors.

It can be very expensive.

I have been using this solution for about four or five years.

Its stability is good.

Its scalability is quite good.

I don't know exactly how many customers are using vSAN because some of our customers install it on their own, but we probably have more than 20 customers.

I haven't had any problems with the solution, but I have heard from a few people that they are a little bit slow in answering the questions.

It is straightforward. The duration depends on the size and the use case, but it usually takes one to four days.

For its implementation, normally, you only need one engineer or admin from the storage team, but sometimes, you need a specialist from the networking/infrastructure team, which is a very important point for vSAN implementation.

It is not a subscription model. It is a purchase model, but it is very important that you also buy technical support from VMware. This is probably the only disadvantage of vSAN. It depends on the use case, but it can be very expensive.

I would recommend this solution for all use cases. It works for all users and customers. It doesn't matter if it is inside the data center or outside the data center. It also works for VDI use cases. It just works.

We have no problems with the vSAN solution, but it is very important that you use the recommended hardware from the compatibility list. If you follow the recommendations from VMware, you should have no problems.

I would rate it a nine out of 10.

We primarily used the solution for development, tests and UAT proposals. We did initially run it without backup and later added Commvault.

introducing vSAN dramatically increased the speed for deployment and decomissioning VMs for developers without the requierement to involve storage team

When we started using vSAN, the speed (performance) of the solution was dramatically higher than the speed of our production systems. 

The integration with the rest of the DVM suite is great as always. The look and feel for the administrators is like a classic virtualization environment and it cannot be better. 

The solution is very easy to set up. 

The stability is good.

We had very good access to technical support.

The ability to access SAN environments via fiber channel (or even NVMe) would be a good addition.

While I do not currently use the product in my new company, I used the solution up until I left my former company. I had used it for nearly six years up until then.

The stability is excellent. There are no bugs or glitches and it doesn't crash or freeze. It's reliable 

In my former company, we had a direct technical account manager. We were very satisfied with the level of assistance we were able to get when we needed it. 

But you have to consider the level of support you purchase and the amount of systems covered by this support - of course a TAM isn't effordable for each and every company.

It was easy to set up. 

If I would have introduce vSAN in an environment without any existing VMWare virtualization deployment and with the intention to expand to cloud based resoruces as a next step, I would not choose the product itself, I would do it with Dell and would implement the VxRail, what is actually vSAN based, it's the same product, however, in the end, you have better services. If you cover hardware and software management as well underneath one GUI, it's better for the administrators.

In the past deployment, it took us about a week to set everything up and to get everything up and running. We did need this week to bring up two 6 node clusters and today, these original six node clusters both expanded to 16 nodes on both sides.

We had a vSAN at my last company. I started my employment here at this new company one month ago and we do not have VMware products at all. Previously, I worked with vSAN simply as a customer and an end-user.

I've used many versions of the solution. We started shortly before the 6.0 came out. We may have started with vSAN 5.5. That was the first version we ever used, and then we upgraded again and again over the years.

I'd advise those considering the solution to think and plan before you simply do. You should do an accounting of what capacities, what performance, which backup you require or have. Do you need redundancy? Do you need network isolation? All the steps that normal people do afterwards should be done before you do it. Everything is about planning.

I'd give the solution a perfect ten out of ten rating. 

We use it everywhere. We power all of our public cloud with it, and we also power all of our customers' private clouds with it. 

Stretched Cluster is one of the big features that we use across multiple data centers.

I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel.

Their level one and level two support is not at all good, and it should be improved.

I have been using this solution for four years.

This is the best product that we've ever used.

It is surely scalable for 64 nodes. We can run petabytes of data if we want. 

Our clients are small to medium companies.

VMware's level one and level two support is not at all good. Their support is good only when you get to level three.

It is cheap. It is $0.02 a gig.

I would advise others to just make sure that latency is brought into the equation because being HCI, network latency determines everything.

I would rate VMware vSAN an eight out of ten.

We use it for localized storage converted into virtual storage. The performance is perfect,  awesome. No complaints.

The most valuable features are

• price point
• you can use existing storage; no specific storage requirements are needed.

I haven't utilized it enough to even know all the features available, much less what might be needed still. It's hitting all of our points pretty well.

The stability is awesome. We love it. 

We haven't dealt that much with scalability because we're rural. It's a small area with small community-type banks. Being able to convert existing storage into vSan is really a perfect solution for a lot of our customers.

I haven't needed to contact technical support yet.

What made us go with this solution was price point. When you can utilize existing storage infrastructure, and not have to continually purchase new SAN products out there that are going up in price as time goes by, then it's a wonderful thing.

When selecting a vSAN vendor, the most important criteria were 

• stability
• dependability
• ease of use
• experience.

I've been using VMware for many years, and I'm still using it. That's a testament to how well it works.

The initial setup was very straightforward, a very simple implementation. It's just an easy product to use. VMware, in general, is a very easy product to use.

The timeframe for return on investment is about three years, and we hit that pretty consistently, if not even sooner.

Look at the ROI carefully, and make sure that you can hit that before pushing the product.

It's cheap, easy, and good for low-end customers. We're a small market, rural area, so we have low-end customers. Price point is just about everything for us.

I would rate vSAN at nine out of ten. What would make it a ten would be lower pricing.

I like this solution because policies (such as resiliency) are applied per virtual disk instead of applied on an entire volume.

In a standard SAN solution, and in almost all software-defined storage solutions, the resiliency is applied to an entire volume. For example, you create a volume (or LUN) and you choose RAID 1, RAID 5, RAID 10 and so on. With vSAN, the notion of volume that we know with SAN doesn’t exist. Instead we have VVOL. Thanks to this, we can apply specific settings like the resiliency per virtual disk. It is more flexible because we don’t need to dedicate an entire volume for a specific resiliency.

I’m a consultant, so I don’t have vSAN in my organization. But customers take this solution to increase efficiency, scalability and ease of management.

Currently, vSAN supports stretched cluster. You need to have the exact same number of nodes in each room and only the RAID 1 resiliency is supported. I hope in the future that vSAN supports also the RAID 5 and RAID 6 resiliency mode for stretched cluster.

I have been working with this solution for seven months.

Some customers report that resync doesn’t work very well.

We have not had scalability issues.

I rate technical support 3.5/5.

As a consultant, I use different solutions, such as Microsoft Storage Spaces Direct, and Nutanix.

The initial setup is straightforward because a wizard helps you to enable vSAN.

The license price is too expensive compared to other market actors.

I will evaluate alternatives depending on customer’s needs, but I compare it with Microsoft Storage Spaces Direct and Nutanix.

Be careful about the chosen hardware, especially HBA, storage devices and CPU depending on deduplication or not.

VMware vSAN is a highly scalable solution. We can start with as few nodes as possible and scale up according to our needs. Another advantage is deploying a stretched solution across two sites, with data synchronization between the two data centers. Setting up a stretch cluster is made easy with vSAN.

VMware vSAN provides seamless integration within the hypervisor core, providing stability and eliminating the need for additional VM gateways per node, as required by solutions like Nutanix. This integration simplifies the ecosystem, making it easier to adopt and manage.

The main improvement in VMware vSAN is its licensing mode. Its acquisition prioritizes doubling the EBITA rather than focusing on technological advancement. This is a common issue in the IT market, where companies may be acquired by financial entities, potentially leading to stagnation in technological innovation. The technology is mature and stable, with no significant improvements currently evident.
The new feature allows for the use of only two nodes in an active-active setup.

I have been using VMware vSAN for eight years.

The performance is up to our expectations. The initial performance is high solution because we use flash storage. The complete solution is good.

The solution’s scalability is good. 200 users are using this solution. We have a private cloud with many intelligent users who can connect to the cloud.

We can manage the solution ourselves. 

There may be an opportunity for vSAN to explore new avenues for open-cycle solutions with the recent reorganization of Broadcom impacting VMware.

We use VMware vSAN with 50 instances, but we must change the licensing. Broadcom buys VMware.

We had been using the Dell VxRail solution. Due to Dell's cessation of collaboration with VMware and Broadcom's decision to overhaul the licensing model, our future with VxRail is uncertain. We can purchase VxRail with vSAN, which is integrated into Dell's portfolio. We lack assurance now that Dell and Broadcom are separate entities.
Overall, I rate the solution a ten out of ten.

We are using VMware vSAN for many purposes, such as NVI workload, edge computing, open run 5G for large customers, onsite installations, and low latency systems like mobile edge computing.

The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system.

The orchestration is well integrated into the stack of the VMware management suite.

VMware vSAN could improve by having faster reload time and a single point of failure. Resynchronization of many hardware could be better. If you have an outage of a disc or a full system, the replication time is too slow. This has room for improvement.

I have used VMware vSAN for approximately three years.

The stability is satisfactory, it has been working well.

VMware vSAN is scalable, it is easy to scale out.

The number of people that use the solution can be anywhere from 1,000 to 10,000,000 depending on the customer.

We are one of the largest customers on the site for this kind of usage worldwide, and the support is very good. We have direct access to the development, R&D, and third-level support, they are very good.

The cost of VMware vSAN is reasonable.

A good solution should be small and fast and at the moment VMware vSAN is the best product that can solve our use cases.

I rate VMware vSAN a five out of ten.

We are a university and we initially designed our data center such that it would be centralized, between branch offices and headquarters. There is a small data center in each branch but we're not interested in having local storage in every one of the branches.

Our plan is to purchase three physical hosts and deploy them with VMware, using vSAN to create virtual storage using each physical host's internal storage. 

The backup features and monitoring features are good.

We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases.

We evaluated and deployed VMware vSAN but have not yet deployed it for production. We will be doing so within the next six months.

This is a stable product. We have been testing it extensively.

Scalability is based on your hardware. We can scale the hardware and then it only requires extending the license.

At this point, we have not had a very heavy workload. We plan to increase our usage once it goes into production.

There is approximately 50 IT staff that have access to it. Our users will include between 30,000 and 35,000 students, and approximately 3,000 staff made up of instructors and doctors. 

The technical support is good. The Ministry of Education has established contracts with all of our vendors including VMware, Microsoft, Oracle, and others. They provide us with 24/7 premium support.

We expect to rely on support for our migration to production. As part of our implementation, we have to redesign the centralized servers for a distributed environment. This includes Active Directory, Microsoft System Center Configuration Manager, and others. We don't have experience in this area. We can handle the daily operations but we lack design experience.

We implemented a PoC for Nutanix but did not test it in a production environment. I have done a little bit of work with Hyper-V but otherwise, I have only worked on traditional architectures.

There is not a lot of maintenance required.

We pay a yearly licensing fee. There are no costs in addition to the standard licensing fees because they are standardized and negotiated by the Ministry of Education.

We provided the sizing and after that, the Ministry arranged for the correct licensing.

We evaluated Nutanix and other hyper-converged solutions, but we choose VMware vSAN.

This is a product that I recommend. My advice for anybody who is implementing it is to use a hybrid or private cloud. It's scalable, robust, and secure. Do not go back to the old technologies. Instead, focus on security and a good design. Having a good design will save in terms of cost.

I would rate this solution an eight out of ten.
