Eric Black - PeerSpot reviewer
The ability to leverage multi-tenancy along with immutability is a huge benefit for us
The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top. Veeam Backup specifically has started to streamline their API, and they are doing that with SOS API. They have optimized it. Any of the S3 devices out there that support this SOS API can have far more API calls at once. On our side, that translates to better restoration. With SOS API, it can leverage far more restorations at a single given time or read from the device in simple terms. That results in maximizing the output and throughput from the device itself.

Achieving seamless cost-saving implementation with exceptional support
The best features that StarWind Virtual SAN offers include the price because comparing to other virtual SAN solutions, this one is the best, and it also has a great support team behind it. My experience with their support has been positive, as their guides regarding the integration are very useful. They have some awesome guides online that show you exactly how to configure the product, how to do the initial setup, and you can speak with them directly. They will be able to connect and verify your setup, run its parameters and see exactly what's working and what is not, and they really help you with that. StarWind Virtual SAN has positively impacted my organization and my customer through initial cost saving. They use this product in a dark site, so I'm not able to provide any additional details about this, but they were really glad about it, they're still using it, and they asked for extending the capacity for it and the support. They really want to use it and are enjoying using it.

Data security and performance excel but integration and licensing need improvement

Quotes from Members

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

Pros

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."
"The initial setup is pretty quick."

"The most valuable features are the Metro clustering, and disaster recovery."
"StarWind saved us about 80% of our storage costs over our old solution."
"Implementing Starwind in our organization has been a game-changer, particularly in terms of cost savings. By leveraging Starwind's virtual tape library (VTL) solution, we have been able to use virtual tapes for our backups, which are then saved in Azure Blob storage."
"This solution has a very good user interface, with simple administration/management."
"Support keeps track of alerts of the system and verifies with us if we need help to fix any issues. They have great and quick technical support."
"The backup is readily available for use, and the restoration process is easy."
"StarWind vSAN has a lot of great features and is a perfect solution for mirroring internal disks and flash between servers."
"Besides being 80% cheaper than the other alternatives, the simplicity makes reconfiguration and support much easier."
"I've had to open a few support cases over the years due to administrator errors, and the support received was top-notch."
"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."
"The solution is simple to configure and provides good performance and less footprint."
"VMware Software Defined Storage gives higher availability against data corruption."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."
"This is an easy-to-use product for adding flexibility to your storage solution."
"The most valuable features of the solution are that it is easy to deploy and the support is really good."
"The single management panel is the main feature that is wonderful for the customer."
 

Cons

"I would like to see more monitoring capability included in the next release of this solution."
"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."
"The only thing I feel FlashBlade is missing is the SOS API. If it had SOS API, that would put it well over the top."
"I would like to see more deduplication."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."
"The Pure Storage Orchestrator is our biggest pain point at the moment. If we can have more say in future developments of feature sets that we will need to support for our use case, that would be pretty beneficial to us."
"I would like to see the licensing fees improved as well as the price per terabytes."
"We just need more integration with Veeam."
"I would like an automated installation/configuration despite the fact that their service is very collaborative, a customer should be able to deploy the solution by themselves."
"I wish there was online support because email return takes a long time and a faster solution should be found."
"Initially, when we first started, the sync was horrible."
"If there was one thing we could request, it would be the ability to shrink volumes. For example, we want to be able to decrease in the size of the volume."
"The interface of the management console of the StarWind Virtual SAN is complex, and it's difficult for the novice user to interact with the management having less knowledge or training in the product."
"A central management console may be nice to see all nodes."
"I would like additional documentation regarding possible networking configurations with 10GbE switching."
"VMware Software Defined Storage should include a shared database on a standard version."
"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."
"It doesn't have the ability to be deployed on any kind of hardware and network connectors."
"I'd like to see improved hardware compatibility"
"The performance is not as good as some competing products and reporting can be improved."
"There is room for more integrations and plugins into more storages."
"The license model of the product is an area of concern where improvements are required."
"Simplifying the licensing model and making it cheaper would improve the solution."
 

Pricing and Cost Advice

"I understand that it is competitively priced compared to other brands."
"It is within reason for what you get. From what we have found comparing it to other vendors, it is in the same range as others. Given the choice, we would definitely redeploy it based on the cost."
"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."
"Our licensing is renewed annually."
"Our customers have seen a reduction in TCO."
"The price of this solution could be made more affordable."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"The pricing for FlashBlade is between cheap and moderate."
"I think that purchasing StarWind Virtual SAN Professional Edition would be optimal for most."
"The license is reusable. We can always rebuild it and apply the license. Then, boom, we get new servers, apply the license, and we're back up and running."
"Once you buy the license, you are free to build your own hardware solution based on your needs."
"The setup cost is very low. The pricing is great."
"This is the best priced solution for an SMB."
"I think the bang for the buck is much better with StarWind Virtual SAN."
"The pricing is more than reasonable."
"I think the cost of this solution is quite fair."
"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."
"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."
"The product is quite expensive and is among the most expensive for this type of solution."
"The solution is very expensive."
"VMware Software Defined Storage is a slightly expensive solution."
