A great solution for fostering the natural expansion of the traditional hybrid culture
Most of the VMware customers I have been engaging with say they have experienced engagement problems. VMware is trying to sell off the VMware enterprise cost and the whole solution is being sold down to a customer, whereas, usually they would try to intentionally avoid talking about the related Windows license. It's not very eye-catching but it's still sizable and we have implemented several Storage Spaces Direct projects for our customers. Currently, we're working hard to replace some of the special storage and hopefully even replace the harder converged storage, etc. Documentation management could be improved. The reason why this product is not being widely accepted by the public is that it doesn't include intuitive streamline, which makes it far from complete. Storage Spaces Direct is powerful and the performance is amazing, but if you need to deliver a high price-performance ratio and visible performance, you need to have expertise in tuning. Many people will not be able to enjoy this opportunity because it's not included in the training. In this case, you need to have a system integrator. A Complete management UI using a web-based interface would be a beneficial feature. They should also use a direct API — currently, they are only using partial API. Often, our customers need to work with other web-based solutions, so they require full API. I am writing my own API for this reason, and our customers are ok with that, but full API would be a very helpful feature that would lead to much more customer satisfaction. Microsoft should provide support for other channels. Microsoft OS supports other channels, but when they become the S2D storage solution, it's very easy to customize the quality. Technically, you can switch channels and replace your storage, but you will need to store away all of the fiber channel equipment, the hardware, and the cables, which can be very expensive.

Easy to set up and maintain with good performance capabilities
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!

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is that there is no single point of failure."
"Its technical support is excellent."
"The flash ability, in terms of tiering and caching, is amazing"
"The initial setup is straightforward."
"The most valuable feature are the caching capabilities using the storage class memory."
"It's mainly about the storage expansion, like in hyper-converged solutions."
"The performance, reliability, and affordability has been most valuable."
"When we need additional storage but want to keep the size of the SANs manageable, the StarWind Virtual SAN has allowed me to do everything needed."
"This solution made it possible to deploy a new infrastructure in the shortest amount of time, at a low cost without purchasing expensive hardware storage, and use unused servers."
"StarWind support has been great in helping resolve other issues not caused by their software."
"It has allowed me to effectively and confidently manage the maintenance of hosts where I can power off a host and have its VMs migrate to another one."
"This solution has a very good user interface, with simple administration/management."
"We went from "no way DB applications would have good performance" to "Wow! We can now actually have a DB running and have some VMs running at the same time.""
"The product's core feature of virtualizing our storage is by far the most valuable."
"It has given the company an almost zero possibility of downtime."
 

Cons

"It is difficult to get a hardware compatibility certification for the solution."
"I think the online documentation needs a lot of work and so do the sizing tools."
"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."
"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."
"More optimization could be done in terms of mirroring."
"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."
"Documentation management could be improved"
"I'd prefer it if a remote console was provided."
"The StarWind Management Console is available only for Microsoft Windows/Windows Server, and should also be available for Linux and macOS, as it would reduce implementation costs."
"I'd love to see more clarification for us folks who are smart enough to do some damage yet not smart enough to use CLI."
"Security on the ISCSI protocol could be improved by adding features like OS-type control access, especially for the data center environment."
"A web management interface would be good, especially for those coming from other solutions that have one."
"There is one issue as far as licensing goes and that is a lack of documentation online for users when transitioning from the free version to the paid version, or vice versa."
"They recommend RAID10 for HDD, which reduces the usable storage capacity."
"I had issues locating the documentation that applied to my version of StarWind vSAN."
 

Pricing and Cost Advice

"Cost-wise the product is one of the more affordable within the category of products."
"The solution is expensive."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"The setup cost is very low. The pricing is great."
"The cost was ultimately low to implement, which allowed us to be 3-2-1 complaint."
"The licensing is a bit weird. If you license the standard version of StarWind, it allows you four terabytes. Then, they have a pro version, but with the pro version, the only difference is it doubles the terabytes to eight."
"The premium support from StarWinds is a must have. The ability to have access to a storage engineer 24/7 is a must for a production environment."
"I think the cost of this solution is quite fair."
"Cost is affordable and licensing is smooth."
"This solution has a great price for the functionality."
"Once you buy the license, you are free to build your own hardware solution based on your needs."
