Achieve cost-effectiveness with superior performance while needing to address cluster support
I am working with Microsoft Storage Spaces Direct for applications, SQL, and VRS. I am an integrator for this solution The price performance is the best advantage of Microsoft Storage Spaces Direct. They introduced the All-Flash array using SSD or NVMe drives without cache drives. It is…

Seamless integrations, high availability, and offers a free version
Although I am generally satisfied with VSAN and its performance, there are some areas that could be improved to enhance its effectiveness even further. One area that could benefit from improvement is scalability. While the tool works well in its current configuration, allowing for greater ease and flexibility in adding new nodes to the cluster without complications would be very beneficial, especially in growing environments. Additionally, I would like to see additional features in the next version, such as better support for automated resource management. This could include proactive suggestions for optimizing storage and memory usage, as well as preventive alerts about the health status of the servers. A more intuitive interface or an improved dashboard for monitoring the cluster would also be helpful, as it would facilitate performance tracking and help identify potential issues before they affect services.

Quotes from Members

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

Pros

"Its technical support is excellent."
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"The flash ability, in terms of tiering and caching, is amazing"
"It's mainly about the storage expansion, like in hyper-converged solutions."
"The most valuable feature is that there is no single point of failure."
"The initial setup is straightforward."
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"The performance, reliability, and affordability has been most valuable."
"When using new (warranty) servers, you can forget about the storage service for several years. The users will not even notice the failure of two servers out of three."
"The ability to run the software virtually on every virtualization platform and the ability to eliminate all storage vendor locking are the most valuable features."
"I save both physical and virtual space."
"The feature I have found most valuable in VSAN is its high availability capability."
"I have found the graphical user interface to be the most useful thing about Virtual SAN."
"The most valuable features are high availability and real-time replication between two servers."
"It enables us to provide more solution options for our clients, with the reassurance that, when implemented, they will be efficient and stable."
"The ability to keep data accessible even in the event of hardware failures is highly valued, as it ensures business continuity."
 

Cons

"Microsoft closed the shared cluster support, which is important for the solution."
"More optimization could be done in terms of mirroring."
"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."
"Microsoft closed the shared cluster support, which is important for the solution."
"It is difficult to get a hardware compatibility certification for the solution."
"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."
"I think the online documentation needs a lot of work and so do the sizing tools."
"Documentation management could be improved"
"More comprehensive reporting and educational resources for error resolution would enhance the user experience."
"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."
"Other vendors such as VMware vSAN have a bigger community of users, so it is easier to find more pre-sale or post-sale information from users."
"I struggled when bit figuring out how to go about doing the evaluation."
"If it's possible to make a driver/solution that does not make use of the iSCSI targets of Windows, that would be great. I don't know if that's possible, however, it could make the configuration a little easier."
"Security on the ISCSI protocol could be improved by adding features like OS-type control access, especially for the data center environment."
"It would be helpful if StarWind provided more precise and detailed documentation explaining how to configure the solution in various scenarios, including the advantages and disadvantages of each."
"I would like to see improvements in the documentation area."
 

Pricing and Cost Advice

"Cost-wise the product is one of the more affordable within the category of products."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"The solution is expensive."
"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."
"It's priced fairly. It was definitely cheaper than the competition. The licensing terms are straightforward and reasonable."
"I think the bang for the buck is much better with StarWind Virtual SAN."
"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."
"The setup cost is very low. The pricing is great."
"When we did all the analysis for StarWind, it was approximately 20 percent less than any of the other solutions that we looked at."
"The pricing is fine for the work that it does."
"This is a good, economical solution compared to data storage systems."
