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.

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

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."
"We have seen a reduction in the total cost of ownership by around 20%."
"The most valuable feature of this solution is performance."
"The main feature I have found to be product replication."
"The most valuable features are the Metro clustering, and disaster recovery."
"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."
"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"The initial setup is pretty easy and simple."
"The most valuable feature are the caching capabilities using the storage class memory."
"The performance, reliability, and affordability has been most valuable."
"The flash ability, in terms of tiering and caching, is amazing"
"The price performance is the best advantage of Microsoft Storage Spaces Direct."
"The initial setup is straightforward."
"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 price performance is the best advantage of Microsoft Storage Spaces Direct."
"It has reduced the amount of switching, network connections, etc., because the converged StarWind Virtual SAN allows us to connect high-speed network interfaces between different boxes instead of having to connect SANs via the network, then connect those two clusters together."
"This solution has a very good user interface, with simple administration/management."
"The feature I have found most valuable in VSAN is its high availability capability."
"Given the high availability of the server cluster, we were able to reduce separate physical servers onto one hyper-converged cluster - this saved in OPEX and CAPEX costs immediately, along with licensing costs of the Windows Server licenses."
"Their support staff is comprised of true experts who can also communicate clearly."
"The customer support provided by StarWind is excellent."
"The management was very easy and I was able to find all that I need in the software dashboard."
"StarWind saved us about 80% of our storage costs over our old solution."
 

Cons

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."
"I would like to see more monitoring capability included in the next release of this solution."
"It would be nice if you could store file-based in the same box with the same technology."
"They need better integration with public clouds along with a better hybrid solution."
"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."
"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."
"There could be improvements in public cloud integration."
"The features provided for SMB customers are limited."
"It is difficult to get a hardware compatibility certification for the solution."
"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."
"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."
"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."
"I think the online documentation needs a lot of work and so do the sizing tools."
"Documentation management could be improved"
"When StarWind Virtual SAN for vSphere nodes go offline unexpectedly, the nodes have to re-sync disks fully which takes a long time. We had a power failure and when both nodes came online, VMware vSphere didn't see StarWind disks before I manually re-scanned them form ESXi administration console even though it should happen automatically"
"The system performs as expected, but we're always looking for performance improvements regarding the best utilization of NVMe disks."
"The documentation is good. However, if compared with competitors, it could be enhanced and made more professional."
"It would be great if it provided thin provisioned virtual disks."
"This is a great product."
"Besides not being able to use any filesystem, I do not have any additional cons."
"We just need more integration with Veeam."
"A better overall view of the different deployments could be beneficial, although this is difficult due to how flexible the solution is."
 

Pricing and Cost Advice

"Our licensing is renewed annually."
"I feel that the price could always be lowered."
"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."
"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 price could be cheaper."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"I understand that it is competitively priced compared to other brands."
"With the data center licensing and everything that is connected to that, this solution is relatively costly."
"Cost-wise the product is one of the more affordable within the category of products."
"The solution is expensive."
"StarWind is a low-cost, full-featured alternative to the traditional SAN environment, and their support will guide you every step of the setup."
"The setup cost is very low. The pricing is great."
"The licensing is straightforward, with free and trial versions available."
"I would suggest that you download the free version, deploy in your lab, and play with it."
"The cost was ultimately low to implement, which allowed us to be 3-2-1 complaint."
"The StarWind VSAN business model is very cost-effective."
"The free version is great to use for labs or test environments."
"The pricing is fine for the work that it does."
