VMware vSAN Reviews

We use the solution for VDI and SBC Citrix.

With this solution, less time is needed to install three-tiered infrastructure.

The main advantage is that it's all in the box, with VMware vCenter Server product.

Compatibility with the previous version, stability, performance, and upgradeability of the solution with the previous version all need to be improved. 

In future releases of the solution, I would like to see more HCL compatibility lists, less hardware requirements, better performance, and the ability to upgrade from the previous version.

I have known vSAN for five years. We deal with the latest version. 

I would rate the stability a six out of ten. It is less stable than Nutanix. 

I would rate the scalability a six out of ten. It is less scalable than Nutanix. 

The customer service and support are poor and not very responsive. We face delays with responses. 

Neutral

We prefer to use Nutanix but if the customer wants to use VMware vSAN, we have no choice.  

The initial setup is very simple. It takes around a few hours to deploy, around two to three hours. It takes more hours than Nutanix takes. 

We do the maintenance for the solution. We have a team of seven engineers for the deployment and maintenance of the solution. 

The hardware price is expensive cause of new vSan 8 Hardware compatibility list. I would rate the licensing model a three out of ten, where one is expensive, and ten is cheap. 

I would rather prefer Nutanix over this solution. Overall, I would rate vSAN solution a six out of ten. 

The use case is when someone is a fan of VMware. No. They can use this technology when they don't want to have an extra storage library. It's integrated into the VMware server. 

And if the employees are familiar with the VMware environment, it's a good storage solution for VMware.

vSAN is integrated into VMware. So you can manage and configure it within the VMware console. That's good. 

There is room for improvement in vSAN's ability to debug. When it's not working well, debugging becomes quite challenging. Identifying issues when it's lagging or not functioning properly can be difficult.

In future releases, I would like to see the ability to debug as a solution.

Other areas of improvement include pricing and support. 

We have deployed vSAM two times for our customers. 

It's very stable, though slightly less than ideal due to the challenge of debugging.

Scalability is not as simple as expected. While it's okay, there are restrictions and complexities. For instance, you need a minimum number of servers for certain functionalities, making it less flexible to adapt. I don't know the prerequisites listed by VMware that are not allowed. 

Initially, you need to have three servers, for example, when deploying the solution. If you want a backup solution, you need to have three servers for that. And if you want to have a mirror of the room, you need to have three more servers. You can't have just two. You need to have three. So, it's not as simple to expand, adapt, or modify due to these strict requirements.

We have around five customers using vSAN. 

The customer service and support are okay. It is not quite good. The support should be faster and more qualified. 

Neutral

The setup is quite easy. It took us around half a day to deploy the solution.

For the deployment process, first, we needed a VMware installation. Then, we identified servers for this solution. License keys were crucial. After that, we proceeded with the setup and configuration.

We need three engineers for the deployment and maintenance of the solution. 

It's quite expensive, even too expensive.

There are some extra costs, which can be quite pricey. But overall, not too many additional expenses.

Overall, I would rate the solution an eight out of ten. 

I would advise ensuring that the VPN destination is a good one and reliable. VMware-listed prerequisites on the websites are important, and clients should confirm services are good before deployment.

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.

This solution has improved our organization by allowing us to implement more quickly, and to ease the maintenance. However, it doesn't change the internal organization much.

The most valuable feature of the solution is the simplicity to implement and to maintain.

One area that could be improved is the management feature. The link between the virtualization layer and the application layer can be improved as well.

An additional feature I would like to see in the next release is integration between virtualization with vSAN and network virtualization.

I've been using the solution for the last three years.

My impression of the stability is that it's a very good solution for our usage.

For the product cloud, scalability is okay. However, when we try to use a larger cloud, we can add more new nodes into the same vSAN configuration.

Every year, our number of users increases.

The customer support is very good, depending on the contract support that you supply. We are using a premium support and the quality is quite good.

The complexity of the initial setup is not really on the VMware, but only the hyper-layer because we need to check if the hyper-layer, underlying VMware are strictly compatible.

For the first implementation, it took more or less one year, but now it takes much less time to add new material and new configuration.

In the beginning, we saw a huge return on investment from VMware, from 10 years ago to five years ago, but now we are used to the product. So the ROI doesn't make much enough for us because we only use vSAN. Now VMware is the baseline.

The product is quite expensive, regarding the open-source solution.

The cost of the solution is a mixture of monthly user and licenses purchasing. So for the internal user, we use licenses purchasing. For an external customer, we use the Pay-Per-View model.

Before choosing VMware, we evaluated Microsoft Nutanix and Cisco HyperFlex. VMware design is more mature than the other solutions, generally.

I would rate the solution a nine out of ten.

Our primary use case is to host our hyperconverged solutions. I'm a project manager and team leader and we are implementers of this solution. We carry out everything from implementation to rollout. We are customers of VMware vSAN.

The VCG notification feature is key for me. 

We faced some latency issues but it's been a little better lately. I'd like to see a single dashboard product and an improvement in reporting which currently depends on third party applications. 

I've been using this solution for almost seven years. 

It's relatively stable now although we had some issues in the past. 

The solution is scalable, we have around 5,000 users. I think there are about 15 people in the company who deal with monitoring, management, and implementation.

We had a very good team early on so we were not dependent on Microsoft or VMware to help mitigate issues.

We previously used Nutanix and I was very happy using Prism. We ended up with vSAN following a bidding process.

The initial setup took around 15 months. It was reasonably simple but there were some issues. We migrated around 150 VMs with applications on them.

We have a deal with them so we don't pay for individual licenses, it's a complete solution with an overall license. 

There are many similar solutions on the market. With VMware you get ease of integration because any new product they bring to the market has VMware. 

I rate this solution an eight out of 10. 

We have vSAN, and have built-in storage capabilities. We have many hosts, and we use the host through our providers with vSAN, with the storage. This improves everything because it is all internally between the servers. We use an NSX protocol. And what NSX does, it uses an internal network between hosts, so there is no use of an external switch. We create an internal connection between the host and the VMware product. So traffic is all internal and you can create all the firewalls and switches, everything. It becomes virtual. But, it is sometimes complicated when you try to deploy new systems or when you have to scale a system very quickly.

I think the vSAN product uses vSphere to monitor the system. It is sometimes difficult to manage the PCs within the system. VMware is currently working towards moving things to the cloud network. This is a great new addition to the VMware product.

To me, it is very stable. I never have problems. I have used VMware for 15 years and I never had any problems with stability. Like any normal system, you may sometimes have problems with one little platform, or with a host that is not working. But, there are no major issues.

We have 130,000 people connected to the platform and to the servers. Eventually, we want to use the cloud, which will help with the volume.

You can speak with VMware and they will provide you service that you need.

I can set up a platform of VMware in a week, easily. It took me about a week to deploy our platform and we basically set up all he servers, all the network and everything else. Then, it took about two or three days to work and patch everything, and cable in everything.

The older versions were a little more complicated. Nowadays, there are more documentations, videos, and tutorials. So, it is less complicated. There are still some issues, until you have to look at everything. But, I think that because there is more documentation now, and more information, you can speak with VMware and they can provide you service.

The only problem I see with VMware is the price tag. This may start causing problems because there are other solutions out there, like AWS, that are open source and free. So, there is no license fee. VMware is very good, but expensive, in comparison.

I compared VMware to Oracle. They're very good, but Oracle is expensive, so people buy it and then start using open-source. Oasis is another option because it's cheaper and it's a similar process. So that is the problem I think VMware is going to have to compete with them in the future, and it is only going to get worse.

To me, VMware is a leader of virtualization. I think everyone just follows VMware. 

The reason why we use VMware is because all of the areas that VMware can provide. They fill a need for our platforms. There are other platforms now that provide similar solutions. In the old days, it was a simple Microsoft platform, and they had no management costs. Now they use VMN to create a cross-test and to link all of the servers they want. So they can provide restoration of servers. Furthermore, now they are integrating the movement towards cloud solutions. The only issues concerning the future of vSAN is the price. If someone builds a platform that is free, and only has to pay a license fee for a server, that may cause a problem for VMware.

The most valuable features are scalability and speed.

The ability to throw in extra disks on the fly and extend storage with no limits is very useful. I already had to do this twice.

I think performance of my vSAN is better than that of a SAN, even though I am only working with 10 VMs per site. I don’t know how many performance hits we would get if I had more VMs.

Typically when you get a SAN, there’s a size limit or cap, adding more storage means buying an extra shelf.

In our environment we use Dell 530’s (8 bays), the original setup was only 4TB of usable storage from a pair, but later just added 2 extra disks per esx to make a 12TB volume, I still have 4 open bays and could easily add 8TB drives there if I needed to and on-the-fly.

In terms of performance, it beats going through the wire, since the disks are on the bus and with caching, iops are a plenty.

Furthermore, we have a power limitation at our communities, and adding one more box (SAN) would require an extra 8amps of juice.

No single point of failure, although SANs are very reliable these days, there’s connections and switches to content, with vSAN you can now connect 2 ESX servers directly not needing a 10GB switch

Refresh cycles: my storage follows my ESX servers, so no more extra new hardware to purchase.

vSAN Robo’s are inexpensive to own and maintain, the enterprise version is a tad more.

I am able to utilize ESX HW at my robo sites without needing to add a SAN or NAS.

I would like to see the following:

• Fixing the resync function. This needs to be addressed ASAP.
• A better UI showing actual space used and disk space available. The current output is very deceiving. It shows a total that should actually be divided in half, minus the headroom.

When disks are getting full or near 70%, there’s a potential for receiving out-of-sync nodes. One node may have more content than the other, and the re-sync button starts a process that never ends. This is a known issue.

When looking at space details, the available free space depicts the sum of the two nodes. In reality, that should only show half and even more. I would like to see a gauge that marks a safe zone, or under 70%.

The reality is that once you go over 70%, the sync issue comes into play, performance hits are unavoidable, and the rebuild could take a long time.

We have used this solution for over a year.

When dealing with seasoned vSAN experts, the experience was outstanding. Getting them to respond quickly is always an issue. I sometimes had to go ahead and perform a rebuild, as it was quicker than waiting for a callback.

The installation was easy.

I deployed it myself with trial and error support from VMware.

The ROI is negative, the capex is OK, but the opex is outrageous. They need to drop the opex to 20%.

See if you can really afford it and make sure you have the expertise on hand to deal with initial deployment issues.

I found that buying a new SAN by Tegile is less expensive, less complex, and very inexpensive to maintain. In addition, support is the best in the business.

Robosites, data center, and Hyper Converged solutions are examples of universal Hyper Converged solutions.

A one-stack solution from one vendor is the main benefit here. 

Additionally, improvements to the organization are not available at this time.

Maybe incorporation of automation to build clusters in a more automated way would be beneficial.

I have been using it for less than one year.

I have no experience with vSAN in production. So, I am not able to provide an answer. I would say it has good reliability.

At the moment, there are zero users. It is only a pilot and lab solution, so no users are onboarded.

I am not satisfied with VMware support, particularly with the reaction times, SLAs, and those kinds of issues.

vSAN and Nutanix convert in hyper-converged solutions.

The setup is straightforward.

The initial setup is managed internally only.

It operates in parallel with others. It is not a replacement.

My overall rating is eight out of ten.
