Solutions Architect at Recovery Point Systems

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.

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 initial setup is pretty easy and simple."

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"The most valuable features are the Metro clustering, and disaster recovery."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

"The most valuable feature of this solution is performance."

"It uses the same platform for connectivity so integration is seamless."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

More Pure Storage FlashBlade pros

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"The initial setup is straightforward."

More StarWind Virtual SAN pros

Cons

"The documentational aspect of FlashBlade needs improvement."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"I would like to have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"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."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"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 features provided for SMB customers are limited."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

More Pure Storage FlashBlade cons

"Documentation management could be improved"

"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."

"It is difficult to get a hardware compatibility certification for the solution."

"Microsoft closed the shared cluster support, which is important for the solution."

"More optimization could be done in terms of mirroring."

"I think the online documentation needs a lot of work and so do the sizing tools."

"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."

More Microsoft Storage Spaces Direct cons

"It would be nice to add the ability to use raw partitions instead of file containers."

"The management console of StarWind Virtual SAN is pretty complex."

"I see no need for major improvements but there could be some improvements in the form of notifications and the simplifying of maintenance mode."

"It would help if the manufacturer provided clearer and more detailed documentation, with explanations of how the application can be installed in various HA configurations."

"While we had no problems setting the system up, and service technicians from StarWind could assist us very well, they could provide some form of in-depth documentation."

"The console is something that I feel could be improved. There is nothing technically wrong with it, but it can be jazzed up and/or made to be a little more intuitive."

"Including their own hyper-visor would be a valuable improvement over simply integrating with Hyper-V."

"While StarWind.com excels in numerous areas, there are a couple of notable functionalities that it currently lacks. One of these is duplication, which could be an invaluable feature for data redundancy and backup purposes. The ability to duplicate data across different storage locations can be crucial for safeguarding against data loss, and its absence is a minor limitation in an otherwise stellar offering."

Pricing and Cost Advice

"Our licensing is renewed annually."

"The pricing for FlashBlade is between cheap and moderate."

"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."

"I rate the tool's pricing a seven to eight out of ten."

"The price could be cheaper."

"Licensing fees are paid yearly."

"I understand that it is competitively priced compared to other brands."

"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."

More Pure Storage FlashBlade 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 cost was ultimately low to implement, which allowed us to be 3-2-1 complaint."

"If you are looking at a traditional SAN for a small cluster, give StarWind vSAN because you will save thousands without any compromise."

"The licensing is straightforward, with free and trial versions available."

"I think that purchasing StarWind Virtual SAN Professional Edition would be optimal for most."
