VMware vSAN Reviews

We use this as storage solution for specific VMware services and for backup solution.

The most valuable feature is stability.

Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it. This should be done automatically, not manually.

If we have a power failure then you have to find your way manually. There 's no way to automatically fix it. So there should be an automatic way to repair such crises from disaster recovery.

In the next release, I would like to see more clarity on where the files are. the details of the files, for example, where the owners of the files are, and more audits.

We have beeing using VSAN for the last three years. 

It is more stable now than it was before. It's not like it was in the first year.

Now it is stable, and we trust it more.

We don't want to enlarge the environment. If we have a new need, we will separate and start a new system.

We don't want to have a general-purpose infrastructure. It's not a good idea for our purposes.

We value less scalability more accurate assessment as it is not the way in our environment. We don't want to add more nodes to the same cluster, it's not a good idea. We separate it.

We get immediate response from the vendor on phone. For tasks onsite its not sufficient.

of course its a matter of service level, no complaints.

No, software solutions from VMware based on VMware platforms no migrations.

The integrator "vendor team" had good experience at the last project. level of expertise was very good.

I would rate this solution an eight out of ten.

Our primary use case for vSAN has been our branch locations and multiple different office locations. We are running vSAN as an alternative to external storage arrays, and it's working really well to provide us with data storage at these branch sites.

The most valuable features of vSAN are its simplicity to deploy and that we can use commodity disks in our servers without complexity or need for external storage arrays or storage specialists on our teams. It's part of our vSphere admin's duties as opposed to storage experts.

The features of vSAN allow us to reduce our operational complexity to a large degree. It's a single pane of glass for the administrator, and we're able to somewhat reduce costs, other than the fact that vSAN is somewhat expensive to license.

I see room for improvement for vSAN just around general hardware compatibility and expanding that sort of matrix. It's pretty wide already, but everything else within vSAN seems to work really well. It is very well-integrated. 

I don't see a lot to complain about at this point.

Stability with vSAN has been really good. We've had very few issues. When we have had maintenance issues, the vSAN has come back and healed them automatically for us. I don't think that we've had to actually engage support a single time in the six months that we've been running vSAN in our corporate office.

I can't really speak to scalability. We have a fairly limited deployment at this point with three nodes, so it's a bare minimum sort of configuration.

We have not had to engage technical support for vSAN. At this point, we've been able to solve all the problems or basically work through the GUI intuitively to be able to resolve anything that has happened.

The decision to switch away from standard array to vSAN was a fairly simple one for us. We had been decreasing the amount of operations that we do inside of our branch sites. For the sites which remain, vSAN is a good fit versus the legacy Dell EMC VNX arrays that we had been deploying. 

We are finding that vSAN is a lot more scalable and adaptable, because we can go in with hybrid arrays for our lower-end storage needs or with all-flash versions of vSAN for places where we need more performance, and it's coming in at a lower cost point than an actual traditional array.

The initial setup for vSAN was extremely simple. There are some concepts that you need to understand before you go in, install, and click the buttons, but once you have your drives configured and inside of the individual nodes, the configuration takes just a few minutes. Everything gets done and orchestrated for you directly from the vSphere or vCenter consoles.

If I had to rate vSAN, I would give it a nine out of ten.

When we're choosing a vendor, we're looking at the ability for the vendor to be in business:

• The viability of the vendor
• Its reputation in the marketplace
• The technical solution.

These have a lot to do with our decision to work with a particular vendor. We typically seek out the best-of-breed solutions and try to adhere to those. At the same time, we try to work with the same vendors over and over, because we have existing relationships to leverage and existing expertise around the solutions that are adjacent to what we may be evaluating.

We use it as a primary storage for our Horizon View environment. 

The product is great. It runs well. 

It helped us survive power outages in one of our data centers, then continued to function without a hitch.

• Its redundancy
• Its uptime capabilities
• The performance is great.

I would like a better Hardware Certification List (HCL). The HCL should a little easier to deal with.

Making the hardware compatibility not as much of an issue would be a good thing. 

It scales well. We have plenty of room to grow. It should be a good long term solution for us.

Technical support has been fantastic. We always get answers quickly whenever we call.

We wanted to give more redundant access to the users' desktops than they previously had. Before, we were on a single SAN which was causing us issues if we had either an issue with the SAN or an issue with our environment when the SAN would go down. By using vSAN, it would allow us to spread our data across multiple data centers on our campus and be more fault tolerant.

It was really straightforward. 

We had some help from Venture Technologies, who helped us get it going. They didn't really have to do too much. We figured it out.

We have increased our user productivity. However, being in Higher Education, we don't really measure it.

Give it a look. It will save you time and money.

The most valuable vSAN features are:

• Ability to scale easy: Adding additional storage is so easy. You just populate an empty HDD slot on the host with a disk and vSAN will automatically add the additional storage to the storage pool. No specialized skills are required.
• Performance and cost/storage efficiency: With vSAN, you get SSD-like performance with a mix of spinning and solid-state disks at a fraction of the cost. We use a ratio of 30/70 SSDs to spinning disks, respectively, for a high-performance SAN that is within our budget.
• Resilience: We tried to break our vSAN PoC instance to test its robustness. We pulled out hard drives while they were being written to and we unplugged server nodes, and we never lost a VM.
• Ease of use: We set up vSAN with a few mouse clicks in vCenter. We couldn’t believe how simple it was to setup and configure.

We are able to deploy vSAN clusters to remote locations very easily at a fraction of the cost. This saves us time and money. We don’t have to worry about stability issues.

Support for iSCSI access would be great, but this may be supported in the latest versions of vSAN.

We have a few physical servers in our environment and it would be great, if these servers could also access the storage in vSAN. With vSAN iSCSI support, we would be able to connect our physical servers to vSAN as well.

We have been using this solution for two years.

In terms of stability, vSAN is very resilient, self-adapting, and self-healing. In the two years that I’ve worked with vSAN, I haven’t experienced any vSAN stability issues.

There haven't been any issues with scalability. Adding additional storage was as simple as inserting a hard drive into a hard drive bay or adding an additional server node to the data center cluster. That was all we had to do, and vSAN auto-configured everything.

We had a VMware vSAN engineer present to set up our very first vSAN cluster. There was nothing to it, but it was great to have an expert on-site for questions and to provide us with training. Other than that, we have never had to log a support request with VMware for vSAN.

We didn’t use a virtual SAN solution previously. We just used traditional, and very expensive, SAN storage arrays. We moved to vSAN because our budget wasn’t getting any bigger, but our storage requirements were increasing.

The setup was straightforward. It literally took a few mouse clicks to setup vSAN.

You get better value for your money with a vSAN solution than with a traditional SAN with lower TCO.

We looked briefly at alternatives, but nothing stood out like vSAN. Nutanix was another solution, but surprisingly, it would have costed us more.

Get a vSAN specialist to come out and spec your vSAN cluster according to your requirements. Have him configure it and test that it is performing properly.

• It's very simple to use.
• It work on commoditized hardware.
• It provides centralized storage.

It's lowered our storage costs while still maintaining High Availability and with easy installation.

Expand the hardware compatibility list – it's pretty short. Definitely also the diagnostic and monitoring could be improved. That stuff is still very new.

We have been using it since it came out in March 2015.

So far so good.

Unsure – all I know is what I read, if it does what it says it does I'm very impressed.

Very good – quality support.

We have three hosts in a cluster, and it was surprisingly easy.

Try it out – that’s the best way to know whether it's right for your organization.

• Integration with VMware vSphere
• It’s simple to manage
• It’s a relatively inexpensive for a SAN solution
• Good performance based on testing

We just started implementation, so it's hard to give our perspective as we're still doing our evaluation. We purchased the product, and we have ten-fold service on it.

If it works out well, storage is our most important element of our infrastructure. We're looking for a stable and high performing solution and think this is it.

I'd like to see support for iSCI. Right now it’s all internal protocols, and they promise it in the next version. They need to support more types of hardware – the list is too narrow.

It's stable, but it's really picky on the hardware. We knew that going in, but the scale was a surprise, not truly as agnostic as we thought it would be. They have a list, and if you deviate a bit, then it won’t support the environment. We had an issue where we deviated slightly, so we probably will have to follow their hardware compatibility list.

Very scalable, it's one of the reasons we bought it. They are in v2.0, and we feel like now it’s mature.

Support is generally good, but a little slow sometimes. You need to stick to their compatibility list if you want their full support.

We were using EMC and we knew we needed something new. Cost is important to look at, because we're nonprofit, as well as the integration with the other VMware products, and the stability of the product too.

Setup is very straightforward.

It’s a good solution – the trend is going towards converged infrastructure. It's all policy based – you can set general policy and then trust VSAN to do everything else.

We use our vSan primarily for our VCF deployment. We run our production workloads on it, mostly for Microsoft SQL databases and various WebSphere and web-based front-end applications.

It performs pretty well for the most part. The older versions had some issues, specifically regarding upgrade paths and the robustness of the product, but in the last two or three versions they've really addressed those issues and brought it up to speed and made it a real enterprise solution.

• Encryption
• Deduplication
• Compression
• The ability to manage all of your storage within your server rack

I would like to see more comprehensive lifecycle management. The current path and process for upgrading or updating the firmware, as well as the storage controller software to interact with that firmware, is fairly manual and not very well documented. A little more time and effort spent on the documentation of the lifecycle management for vSan would be really great.

Currently, it's very stable. Previous versions, which are still active and out there online: upgrade to the new version.

Scalability is slightly limited in that you're pinned by the physical disks in your hosts, but provided that your solution doesn't require you to have specific disk technology, you can get the size you need and expand it out as much as you need to.

I give technical support an A-plus, from my experience. It was perfect, it was awesome. They helped us recover from a very major outage and we would have been down for much longer had they not been involved.

We were on old hardware and we needed to move to a new solution.

It completely removes the need for a storage network and for a storage administrator and all of that infrastructure and the costs that are involved with them. That, right there, is a huge return.

It's great for DevTest and, as long as you're not going to be consuming data at huge rates, it's great for Prod too.

I would rate vSAN as six-and-a-half or seven out of ten, but only because of the major problems we experienced with them a few months ago that led to some big outages. From what I understand, the current version alleviates those issues. If we're evaluating the current version, I would give it an eight.

It would be a ten if there were more robust lifecycle management and a better-documented implementation within vSphere.

We had several servers we used in our VMware cluster, as well as a storage device. The implementation of vSAN reduced the rack space, since we no longer required several slots in the cabinet to rack a storage device. vSAN also made it very easy for us to scale out. Power consumption was also reduced within our datacentre.

I like the scalability and the fact that it reduces your total cost for storage over several years.

The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI. They have already made several improvements in vSAN 6.2, but there's always room for improvement when it comes to monitoring performance.

We had no stability issues.

We had no scalability issues.

VMware technical support provides a great service.

We switched to move towards a software-defined datacentre.

It is very easy to configure and setup. vSAN is already part of vSphere ESXi. You simple need to apply a license and do minor configuration to get it to work.

The first 1-2 years of purchasing vSAN will be expensive. Thereafter, the longer you are running it, the more cost savings you will have.

We looked into several other products, such as Pure Storage and Dell solutions.

Keep it simple, and don’t try and over-complicate things. Make sure to follow VMware best practices when it comes to implementing your vSAN solution. Read those whitepapers and make sure you understand how you want to implement it in your environment.
