VMware vSAN Reviews

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.

In a lot of cases, the primary use case for vSAN is in small to medium businesses, where they may not have the space or the funds for an actual storage array to provide a shared storage medium for their virtual environment. And even if they do, they may not have the expertise to maintain that and a separate network. vSAN gives them the ability to make use of storage they already own, across their host. As they add more, more storage, more compute, they'll add more memory. It makes their environment simpler to manage and keeps it moving smoothly for them.

The most valuable feature is the simplicity of its scalability: being able to grow it without having to make sure you get the right disks and the right nodes.

The solution is also easy to manage. It's all right there in the vSphere Client. You're not going through multiple things. You don't have to know, once you've created the vSAN node. You add storage, it sees it, and you create your data storage from there. Everything is right there for you.

What I would like to see,  for the really small customers, is the ability to have two nodes.

I find it to be incredibly stable.

I've seen it scale up to large databases. I've got some customers who utilize a small vSAN cluster for their Exchange environments because it keeps it encapsulated for them.

The initial setup is very straightforward.

I would definitely go with the vSAN solution. A lot of times, it's less expensive than third-party software, and it's not managed via third-party plugins. It's there, it's native to the ecosystem, and it works.

We are an implementation partner for VMware vSAN and we use it alongside our hyperconverged infrastructure solutions with products such as Nutanix, HyperFlex, and SimpliVity. It is currently implemented in key areas off-site for over seven customers.

The most valuable thing about vSAN is that all of its features have been working well for us for the past two years. We haven't had an issue with them.

When designing the implementation for vSAN, I have noticed that it requires a minimum of six nodes, and this creates a problem when it comes to maintenance. If, out of the six nodes, I put one node in maintenance mode, then vSAN does not create other VM components. I think the reason for this is that the minimum configuration is a six node arrangement. If any one of the six nodes is put into maintenance mode, we're simply unable to create a VM, but if there are seven nodes in that cluster, then we are able to put one under maintenance. That's one thing that should be looked at.

More generally, the features of vSAN as we see them are dependent on the quality of the storage, since each different storage technology has its own separate features that go along with it.

I have been working with VMware vSAN for at least two years. 

It is a stable product, especially now that we have it fully implemented. However, if any two or three of the nodes go away, vSAN goes down. I think we've had a few VMs where the data has been lost for this reason. I guess that the way it works would be similar to other technologies, but that's what we have observed.

You can increase the compute capability as well as the disk storage, so it is scalable.

I've already escalated the issue regarding the six nodes, which I've mentioned. This has been escalated to VMware and they know that it is a limitation, because apparently it is normal behavior for any nodes that are put in maintenance mode.

The setup is easy.

We have been working with vSAN for the last two years, and we haven't seen too many issues overall, but because of the troubles we have faced with the fact that vSAN doesn't let you put a node in maintenance mode unless you have six or more nodes, I would rate VMware vSAN a six out of ten.

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.

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.

• It's easy to implement.
• It performs very well.

The total cost of ownership, as it's really cheap for us and we have budgetary constraints. Plus, as we're a hospital, doctors need to access their patient data quickly, which VSAN allows them to do.

We haven’t had an issue and we've been using it for about six months now.

I find it’s easy to scale, so if you need 100 more VMs, you know the amount of users per node, and you know exactly how much it’s going to cost you to scale up.

Never had an issue.

The only thing is that as we were early adopters, we found tech support was difficult to deal with because our hardware was Cisco, and they didn’t know what we were talking about.

We had one issue with an MTU, but it didn't take me even a day to set up.

Basically we're a one man shop – we like to keep our list short and simple: VMWare and Cisco.

Try it out. It’s worth it.

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.

The vSAN is similar to other VMware products that are quite popular in Thailand. Everyone uses virtualization to more efficiently utilize hardware resources. That's the main point of vSAN and VMware.

The UI falls short compared to other solutions. It needs some development to make it more user-friendly. 

I've been using vSAN for six years. 

vSAN isn't easy to install, because it's separate from VMware. You have to install vSAN and monitoring separately. Configuration is not straightforward. You have to define the policy first and then allocate through the virtual machine.

We used the VMware professional team to install, and it took them around two days. After it was deployed, we used one engineer to maintain the system.

The license for vSAN is a yearly subscription. 

I would rate vSAN seven out 10.
