StarWind Virtual SAN Reviews

I write this from a value-added reseller (VAR) point of view. 

StarWind Virtual SAN provides us with a number of benefits:

StarWind Virtual SAN is a cost-effective solution, as it does not require additional licensing costs. This can help VARs to offer competitive pricing to their customers.

StarWind Virtual SAN is a highly flexible solution, as it can be deployed on physical servers or on top of virtual machines running on hypervisors such as VMware vSphere and Microsoft Hyper-V. This allows VARs to offer a solution that can be tailored to the specific needs of their customers.

From my point of view, we offer this product and it is installed, tested, and configured on our client hardware, often located in the public and private sectors in the UK. 

StarWind is known for its good technical support and customer service. This helps us to offer a solution that is supported by a reliable vendor, which in turn improves customer satisfaction and ensures sticky and repeat business for future activities. 

StarWind Virtual SAN fills a gap for our clients who can't justify the expensive hardware from Nutanix, HPE etc. Virtual SAN offers an opportunity to repurpose hardware or use non-badged hardware for a very high-end storage solution. This directly benefits my company and me since we are able to cater to this gap in the market.   

StarWind Virtual SAN supports both block and file storage protocols, which provides me with more options to choose from when placing Virtual SAN for a given role and client based on my customers' specific use cases and requirements. 

Data compression, deduplication, and snapshots help optimize storage utilization and protect data. 

This helps me to offer a solution that can help our customers to improve storage utilization and protect data at an affordable price, cutting out expensive enterprise-grade hardware.

Geolocation could be better, for example, for site mirroring for DR purposes. I would like a future release to explore the possibility of secure, reliable site replication. 

Disaster recovery site mirroring would provide several benefits, including business continuity. A disaster recovery site can be used to restore critical systems and operations in the event of a disaster, ensuring that the business can continue functioning.

The deduplication feature could also be more robust. That said, I am comparing it to the features of an HPE Nimble, which is a really unfair comparison given the cost difference.

I've used the solution for two to three years.

The software is very stable, and I have personally never witnessed downtime if the hardware use exceeds the minimum requirements.

The solution is not too scalable to geo-site redundancy. This could be a future feature.

Support is timely, knowledgeable, and has good availability with lots of different contact options including phone, email, web, etc.

Positive

We used to use VMware vSAN.

The guides and support are very detailed. There is a large community that also runs this in their home labs. They are giving lots of community feedback, ideas, and solutions to problems you may encounter.

I am speaking from a vendor point of view.

I would advise users to contact StarWind directly since we have always found they support pre and post-sales and are amazingly knowledgeable.  

We looked into various hardware and software offerings from Nutanix, NetApp, and HPE. StarWind fills the void when the budget does not allow for the expensive hardware, and we have older systems we can repurpose.

We exclusively use StarWind vSAN for our virtualization data stores. We have:

VMware: 50 physical hosts, 500 virtual machines
Hyper-V: 10 physical hosts, 100 virtual machines
Internal SAN: 250 users, 50 shares
Disaster Recovery: off-site replication

We currently have 75 data stores across 24 servers.

Primary Performance Cluster:
Eight 72 SSD chassis and a 512 GB RAM cache
A-A-A (three-way high-availability) across servers

Primary Storage Cluster:
Four 36 HDD chassis and a 512 GB RAM cache
A-A-A (three-way high-availability) across servers

StarWind vSAN has allowed us to grow rapidly while still providing flexibility and reliability. We have not had a complete outage since migrating in 2012. I cannot recommend them enough.

We have completely rebuilt and upgraded our storage infrastructure five times. We could migrate data seamlessly in our live environment without downtime.

We primarily use Supermicro hardware for our storage servers, although not exclusively.

Having a solution that is flexible enough to synchronize between many different hardware vendors is extremely valuable.

The three-way high availability (A-A-A) is very useful.

I have never found another product that can provide this redundancy and performance.

We have a complex and demanding environment that requires the ability to scale out while in production. We have utilized StarWind to achieve those needs.

We were the victim of a ransomware attack that was devastating. StarWind ensured we were completely unaffected and it preserved our virtualization environment. Our SAN was completely encrypted, but with off-site asynchronous replication, we were able to restore all our files quickly.

There is no IPv6 support. That is our only issue at this time.

The support team is exceptional, and we have always been able to overcome any of the technical issues we have had. I cannot recommend them enough!

Our wish list includes:

• A Linux install package for vSAN (not just a VM)
• Central management that supports all of the StarWind services and can provide a network operations level dashboard with customizable alerts (possibly with a mobile app companion with push notifications)
• IPv6 support
  

I've used the solution since 2012.

Scalability is one of the things we absolutely love about StarWind. We have scaled from two servers providing 20 TB to 24 servers providing 2 PB.

I have talked to all levels of support over the years, including the developers. They have an amazing product and an exceptional support team.

Positive

We did use something else and originally switched as no other solution at the time had real high availability. Most products just offered fail-over options.

The initial setup was fairly straightforward.

We have evolved into a much more complex environment over time.

We handled the setup in-house.

We have been using StarWind since 2012. Our ROI was seen within the first six months.

Users should know that licensing can be reallocated as you retire old servers. I recommend always buying unlimited licenses as needed unless you think you can utilize their data center license.

We looked into:

• Open-E
• HPE
  
• VMware
• Microsoft

I'd advise others to download their evaluation and test it in multiple scenarios. You will fall in love with their product!

We use the solution for HA storage for HVs.

We are an SMB that can't be bothered paying tens of thousands of dollars just to get a proper HA storage for a two node failover cluster. Therefore StarWind's vSAN was financially attractive from the start.

The reviews you can find all over the web incentivised us to research this solution deeper (e.g. just check all the great posts vom Kooler on Stackoverflow), leading to us actually implementing it.

We were coming from an S2D implementation which already gave us a ridiculous amount of headaches (bugs, performance stalls, "we know what's best for you" automatisms) in addition to being slow and annoying to administrate/debug while also having the most annoying documentation ever to be created by mankind. These solutions rush out some code and ship it and never fix anything (but break it every few weeks with patches).

The initial tests were easily implementable (without begging some sales folks for a POC, due to a free version being available) as well as proper documentation that you actually like to read due to it having been typed by a tech (and that also isn't behind a pay/registration wall).

As close to perfect as the documentation is, do read the blog posts to the two-node HA setup as well. Some minute details were only found in those.
There are no showstoppers, and not many things in general, just a few hints here and there.

The install itself is easy as pie. The config file is properly documented (you can do most things via GUI, just some things are set in the main config file).

Do help yourself to the iSCSI Powershell commands (Windows defaults from MS) when implementing. It is way more attractive than clicking via GUI.
(New-IscsiTargetPortal, Connect-IscsiTarget etc.)

Some things must be done via GUI though, since iSCSI has been implemented way back and "making scripting available" wasn't that widespread for developers back then. This being a Microsoft topic, not StarWind though. They would have had to make their very own iSCSI implementation otherwise.

For testing, you should use a proper tool like https://docs.microsoft.com/en-...
since "Windows copy from within the VM running on the test setup" can be flakey.
Not as in "the results aren't valid real world performance if you check with the Windows copy within a VM" but rather "non-scientific" since you can't extract much data from that process aside from size/time.

There is a visual bug with a specific part of iSCSI. It's Microsoft's fault, and, as usual, has never been fixed in over 15 years. Just don't panic if you experience it.
https://www.dell.com/support/k...
https://social.technet.microso...

Price-wise this is very attractive. The support is great (little that we needed due to the good docs) and I would expect you to reach a very good performance just like we did.

The next-best solution from my research back then - that you would actually want to use, so no S2D or anything - would have started at 7X or 8X the price. Since StarWind's solution has served us very well over the last two years already, I would recommend it.

To respond to the "how it has improved our organization," in a nutshell: it has provided very stable and performant storage-level HA which allows for live failover of VMs (as long as the compute doesn't die as well).

We like the ability to be installed and used on the same host, so we get the max performance possible.

It is easy to set up and maintain, resulting in a happy admin and low TCO/good ROI.

It offers good performance and stability and also makes for a happy admin.

It provides HA for our failover cluster storage where anything can go wrong up until compute, the thing still chugs along like nothing ever happened.

The upgrades are also very easy to implement. It's basically "click click click" once everything has been shut down and you're back up really quickly.

Feature-wise we are only waiting for the release of a "planned disaster" feature that would allow us to patch a hypervisor node without having to take the full storage offline.

ATM (20220609) is still necessary, since taking a node offline without properly activating the maintenance mode on the vSAN would trigger a full sync of the vSAN nodes.

This is fine and a good thing since it ensures data integrity. However, there is something in the making that would ensure integrity without a full sync after a node goes down, which, as stated above, one could "abuse" to patch (and boot = take down) the hypervisors during business hours 😁

Other than that, the thing is rock stable and chugging along without issues.
We are an SMB so we "only" have around 50 VMs on our FO cluster, which is a medium load for SSDs.

If you plan to go more to the "max" side of performance use, do proper testing!

I've used the solution for two years.

It's rock-stable.

So far, we only had visual issues in a specific place due to Microsoft being a PITA and never fixing any bugs they bring in (this one being over 15 years old).

It scales very easily.

Depending on your setup, their actual SAN might be a better fit for you, however, that's for your very specific case to decide.

We really only had contacted the support for the final checkup after setting it up ourselves, so that they could verify everything is running as it is supposed to.

That was great, so our experience has been great overall.

Positive

We previously used Microsoft S2D. It had bad documentation, offered bad performance, and had bad GUI and bad CLI.

The setup is very easy, and they offer very nice documentation and blog posts.

We did the implementation all in-house, self-taught by their great docs.

Since our HVs already run with Windows DC we had S2D included in the cost.

However, the operational costs were high. I'd easily say the invested time over a year with S2D would be $20-30K while StarWind's vSAN now took like $500-750 (yes, less than $1K!) over two years. 😎

Even if you add the license cost (which is cheap even with our 3-year premium support package) it is a no-brainer.

There is the "invisible" cost of you reading the docs, however, that comes with every solution. At least with StarWind, you have tech-to-tech documentation that you can actually use.

The pricing is very fair!

We looked into VMware and others. They usually had a way higher cost or worse performance or worse GUI/documentation, or all of those things together.

I'd advise others to use the free license to test it. The doc is also public. This is the way.

We use the solution to create a highly available server cluster. 

I currently have two physical servers running 25 virtual machines in a highly available cluster. StarWind Virtual SAN enables this without any extra hardware and any kind of hardware vendor locking. 

We use the vSAN product to run a production cluster but also a secondary cluster that houses low-level and testing servers. StarWind vSAN is used to cluster everything together into a solid hyper-converged structure that requires less hardware, less energy, and far less maintenance.

I have been able to do more with less hardware. StarWind vSAN allows us to create a hyper-converged server cluster on a friendly budget without being locked into a specific hardware vendor. 

The product, server, and support are top tier. Their proactive support is on top of every little anomaly in the vSAN. The product is fairly simple to get running and operates with little overhead. 

It makes setting up a high available environment easy and very manageable. Everyone from sales to support are very engaged and proud of the product.

The most valuable aspects are the support and the high availability.

They offer top-tier support. The support staff is knowledgeable and very willing to help. The proactive support option is unlike any support I've ever dealt with. If anything gets out of sorts, the team is on top of it with an email.

Achieving a highly available environment can be hard to execute and lead to a hardware vendor lockin. StarWind is hardware agnostic and supports as few as two hosts to create a fully functional, hyper-converged, highly available server cluster at a fraction of the cost of other vendors.

A good area of improvement would be at the level at which StarWind vSAN is managed. Currently, the StarWind management console is a bit clunky to navigate and isn't the most user intuitive interface. It gets the job done, however, following guides and documentation is highly advised to make sure things are being set up correctly. 

Another area of improvement would be the ability to manage your entire setup using StarWind software. Hyper-V, for example, still needs to be managed using a manager and failover cluster. Combining these into the StarWind product would be a game changer.

I've used the solution for five years.

The solution is very stable. It's been running for five years with nearly no problems in the software itself.

You can start with just two nodes and scale from there. It's very helpful.

The technical support is A+.

Positive

We did not use a different solution previously.

The initial setup is straightforward. The support helps with the initial setup. I had to rebuild a cluster once and support also assisted with that process.

We handled the setup in-house with the manufacturer.

The product offers a very straightforward cost model versus its competitors.

We did also evaluate VMware, Nutanix, and Scale.

We have utilized StarWind Virtual SAN (vSAN) as an iSCSI server alternative in a Hyper-V based installation. We ran a 30-day trial license in a lab environment. The StarWind vSAN solution was used as a software-defined iSCI storage solution for an imminent SQL Server cluster installation. This allowed us for a fairly quick integration solution for our SQL Server cluster shared disk requirements, without the need to invest in a high-cost Storage Area Network (SAN) solution. 

It is a good practice to use storage performance evaluation tools, such as Microsoft DiskSPD, to evaluate IOPS metrics and perform stress testing in a lab environment with synthetic transactions for your prospective application. In our case, we conducted synthetic transactions for stress testing to prepare for a SQL server failover cluster installation.

There are various reasons that led us to pick StarWind vSAN for our implementation. 

Firstly, because it offers a robust iSCSI-based virtual server which is software-defined and comes at a fraction of the cost, as compared to buying an expensive hardware Storage Area Network (SAN). 

Secondly, because it is compatible with KVM. We do implementations based on the KVM hypervisor besides HyperV and VMware, and StarWind vSAN is among a limited number of platforms which offer native support for KVM. 

Last but not least, it offers a fully functional trial license to test the product in a lab environment in a variety of deployment options, including both Linux-based virtual appliances and Windows-based executables.

StarWind Virtual SAN (vSAN) offers a significant breadth of features. The ones which were the most significant and value-adding in our topology and implementation included the overall admin and user-friendliness of the solution and the rapid deployment times gave us a platform for a very quick-to-market solution for our SQL Server cluster-based applications. It allowed us to develop a solution in less than 30 days with less than one-third of the overall estimated cost investment compared to a traditional hardware-based SAN.

The StarWind vSAN solution is versatile and offers broad support for different hypervisors and deployment formats. During our evaluation of our on-premises setup, we did not find any significant flaws. 

One point for improvement is to increase the performance capabilities of the Windows-based executable as compared to its Linux Controller Virtual Machine (CVM) equivalent. 

Another point for improvement would be to incorporate a more granular Role-based access control system (RBAC) natively inside the software to allow for more granular administration. 

Yet another point would be to achieve tighter integration and automation with cloud-based platforms, such as Microsoft Azure and Amazon Web Services (AWS).

I have used StarWind vSAN installations in a lab environment on many occasions over the past five years; the most recent of which was during a 30-day trial run in 2024.

There have been no dropouts nor any downtime during the deployment and during the evaluation operations of the product with our SQL Server cluster instances.

StarWind vSAN performs steadily under heavy usage and can scale well if needed to support larger-scale systems. In our case it supported a significant number of clustered SQL Server instances without any issues in scaling up when needed.

The customer service and sales team have been very responsive and helpful throughout the evaluation of the product.

Positive

We have used hardware-based SAN solutions based on the IBM V5000 series. We did not switch this solution. We continue to trust IBM V5000 and V7000 solutions for higher-end implementations, where budget is not an issue. In cases of lower budget and quick time-to-market implementations, though, StarWind vSAN has helped us make good progress.

The setup was straight forward in most aspects and it was based on a well documented step-by-step procedure, which was provided by the vendor.

Implementation was an in-house one.

Make the most of your 30-day trial license, and if needed, you should contact the sales department of StarWind to extend the trial license or upgrade to a full license. 

We based our decision on previous positive experience with StarWind vSAN. Also due to brevity of time and tight project timeframe, there was no sufficient time for evaluating other options.

I would advise that you implement the Linux-based Controller Virtual Machine (CVM) during your evaluation phase, since the expected performance metrics are better, as compared to Windows-based executable. 

As per StarWind software documentation, the Linux-based CVM offers a a wide range of features, better performance, and stability, including reduced CPU usage and lower I/O latency.

We needed redundancy in our "dark" environment. A failover cluster was the best solution for us. We have a complicated infrastructure consisting of various v-hosts and over 40 VMs in all kinds of operating systems. 

For continuity, it was necessary to update our VMs without any downtime. It's installed on two v-hosts with the most important machines. This way, we can continue operations without hick-ups. We chose StarWind as it's independent of the hardware used in our v-hosts. We did look at other solutions; however, in the end, StarWind VSAN was the best choice for us.

We needed a redundant solution for our environment, and it was sufficient to have a two-node cluster. 

The implementation went flawlessly with the help of StarWind support. However, technical knowledge is mandatory. Nevertheless, we had a quick installation. Since we had lots of different types of storage available, we were able to assign different types of storage depending on the type of usage for the virtual machines. 

We already had an unexpected outage of one of the nodes due to a memory problem, and thanks to StarWind vSAN, our operations continued as expected. It's an easy way to keep your failover cluster monitored.

StarWind vSAN is easy to use and has a very clear GUI. The most valuable in StarWind vSAN is the way it works seamlessly with the Microsoft fail-over cluster. 

We are working with a two-node setup that suits our needs perfectly. It just works without any technical know-how needed. 

The best part is the easy way it operates with a very clear GUI without any unnecessary items. 

It's also easy to add an extra node if necessary or connect if you've rebooted one of the nodes. Also, the speed of support is very valuable to us. If you have a problem or question, you'll get almost an immediate answer.

The product is as good as it promises. 

StarWind vSAN is updated on a regular basis, probably to keep up with Microsoft Windows or other operating systems. As far as I'm concerned, there should be some kind of active monitoring connected to StarWind vSAN, so you will be able to act when needed. 

In our dark environment, this is impossible as we don't have any mail server available in our infrastructure, which consists of a few v-hosts, redundant storage, and quite a few virtual machines, all running on Microsoft OS.

I've used the solution for three years.

In my company, we employ a sophisticated infrastructure comprised of three distinct hypervisors and a dedicated storage server featuring vSAN technology. This intricate setup serves as the backbone for delivering a diverse range of services to our clients, encompassing web hosting plans, secure and efficient file sharing, compute power, and bespoke storage solutions. 

Leveraging the flexibility of multiple hypervisors allows us to scale our services to meet the unique requirements of our clients, ensuring optimal performance and resource allocation. 

It also acts as the centralized storage for my home environment as well. Within my home setup, this robust virtualized storage solution plays a role in supporting various functionalities, including the storage and retrieval of data from surveillance cameras. 

It also provides a seamless and efficient solution for personal storage requirements, showcasing the versatility and scalability of my Virtual SAN configuration.

Hypervisor offers agnosticism for flexibility. My company could seamlessly transition workloads on VMware without worrying about storage compatibility issues.

It has dynamic workload management. As business requirements change, my company might need to migrate virtual machines (VMs) between two or three (or more) hypervisors based on performance, licensing, or other considerations. With Virtual SAN, I can easily move VMs without the need for complex storage transformations and involving other solutions.

The customizability and reliability of Virtual SAN setup in our infrastructure stand out as the key pillars supporting the seamless delivery of services to my clients. 

The ability to provide my virtualization environment to meet specific client needs ensures that we can meet diverse requirements, from web hosting plans to file sharing and storage solutions. This degree of customization not only enhances the client experience but also allows us to optimize resource utilization and calculate future improvements.

Moreover, the reliability of Virtual SAN plays a critical role in maintaining the stability and availability of my services. The redundant and fault-tolerant features in the Virtual SAN architecture provide a resilient infrastructure that minimizes downtime and ensures a consistent and reliable service for my clients.

Embarking on a 14-day GUI trial is a good approach for enabling an exploration of Virtual SAN's capabilities. This period can facilitate a better understanding of real-world performance, interface, and overall system suitability. 

By affording users the opportunity to dive deeply into the product's features, this trial can ensure a comprehensive evaluation, regarding the adoption of Virtual SAN.

An extended trial period would serve as a way to get clean insights into the technology's adaptability and alignment with their specific needs before committing to long-term integration.

I've only used the solution for one year.

In a Hyper-V environment running Windows Server, we needed high availability in a virtualized environment for our file-share cluster without having to use expensive, external iSCSI storage. Using the built-in VDHX disks, StarWind provides the high availability that we need at a low cost and is relatively easy to manage. We now have a 2-node, fault-tolerant file-share cluster that behaves exactly as we want and it utilizes StarWind to provide the high availability directly on the VMs themselves, rather than connecting an external storage.

With StarWind Virtual SAN we have a cost-effective, reliable, and easy-to-manage solution without having to spend a lot of money on external SAN or NAS solutions that would have cost a lot more, and would have required more infrastructure to manage. Instead, for a little sum and a setup that took less than a day, the virtual SAN runs directly on the VMs and is easy enough to manage that a single technician can do it. 

Most of the time, you don't even need to check on it as it just works once you have it set up. This saves money and time and you can cut down on your infrastructure needs.

Simply put, the best features of StarWind Virtual SAN are its core offerings:

- The fault-tolerant, high availability features using virtualized software. You can turn your local disk storage into high-availability iSCSI storage! It's so good, I can't believe Microsoft doesn't include this natively. Thankfully StarWind does the job.

- Ease of use; once set up, it just works and you don't have to spend a lot of time managing it. 

- It's very cost-effective. There's even a free version license to use with a two- or three-node cluster. You don't have to purchase or manage a costly, external storage infrastructure that would essentially provide a similar service.

There is a general lack of documentation, especially up-to-date documentation to get started. This is especially true if you want to trial the software first using the free version, as some of the documentation that exists is sometimes old and certain steps provided might not be very easy to understand. 

The free license only allows you to manage the setup via the CLI (the GUI works, but only provides information), which makes good documentation all the more important. 

The GUI itself as well could use an overhaul; the user experience is a bit lacking until you get the feel for it. 

I implemented StarWind Virtual SAN in our environment in early 2023.

Once we had it set up, it just works. I can't remember the last time I had to check on the software to see that all was in order. StarWind seems very stable and reliable.

We only use a two-node cluster. I have not tested the software outside of this configuration, however, if you're building a much bigger cluster, you'd probably be better off investing in an external, dedicated storage solution such as a SAN. 

The one time I had to contact support, they were very good and I got the impression they understand storage and their product.

Positive

We did not have any other solutions before this, this was a whole new use case.

We first tried the free edition, and due to some documentation being a little outdated, there were some issues as all we had the CLI to use. Once we went through it again though, it was fairly easy to set up. 

Even for someone who has never used the software before, within a single day it was up and running. If you pay for the license, using the GUI is a breeze, even if the GUI as well takes some time to get used to and understand where to find things.

We (I) did it in-house, and once I got comfortable with it, it was easy to set up.

We save money and time on having this solution, as there's less infrastructure to manage, we have high availability where we need it, and it's much more cost-effective than any other option.

Try the free version first, as it's perfectly capable to be used and provides the same functionality (without the GUI) as the paid version. You can then simply upgrade. It does take a little bit of time to get used to managing it with the CLI, but once it's set up, it's a breeze.

We did check for options, but as we are running Hyper-V natively, there were not a lot of options as we didn't have the budget to go for an expensive hardware solution, and Microsoft does not provide a solution to this problem in the same way that VMWare for example does.

StarWind is the best, and most cost-effective option that we have found on the market.
