Eric Black

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

"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 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 snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

"We can capacity plan at a greater level than we used to."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"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."

"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 solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

More Pure Storage FlashBlade pros

"Its technical support is excellent."

"The performance, reliability, and affordability has been most valuable."

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

"The initial setup is straightforward."

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

"It's mainly about the storage expansion, like in hyper-converged solutions."

"The most valuable feature are the caching capabilities using the storage class memory."

"The most valuable feature is that there is no single point of failure."

More Microsoft Storage Spaces Direct pros

"It has improved our organization in terms of its uptime as our main cluster has never been offline due to a SAN failure."

"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."

"As the client had acquired another company some distance away, they were concerned about having a single SAN in one location or the other. StarWind vSAN allowed us to keep a copy of the data local to each site without asking the client to pay for two SANs in addition to the two new servers they needed."

"We are able to do maintenance by bringing down one node at a time, rather than having to schedule a complete shutdown."

"The install itself is easy as pie."

"The product only requires two VMWare ESXi host servers versus three host servers for VMware's comparable solution."

"It includes every feature that a traditional SAN offers and so much more."

"The solution provides great performance for the price it is listed with."

More StarWind Virtual SAN pros

Cons

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"Its configuration should be easier."

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

"I would like to see more deduplication."

"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 also like to see better support for CIFS workloads."

"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."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

More Pure Storage FlashBlade cons

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

"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."

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

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

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

"Documentation management could be improved"

More Microsoft Storage Spaces Direct cons

"Some of the documentation seems to be a bit older and refers to deprecated items."

"Android app for monitoring and receiving push notifications as alarms or monitoring I/O from any mobile device could be a good feature and nice to have as we are not always on our desk."

"There is a general lack of documentation, especially up-to-date documentation to get started."

"The documentation could be clearer in terms of explaining the installation."

"The setup and documentation for the installation with the free version could definitely be improved."

"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."

"Besides not being able to use any filesystem, I do not have any additional cons."

"Proper training sessions should be included with the licensing."

More StarWind Virtual SAN cons

Pricing and Cost Advice

"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."

"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 customers have seen a reduction in TCO."

"The product is very expensive."

"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."

"I have seen ROI. It has allowed me to increase the density of my VMs without having to purchase anything additional."

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

More Pure Storage FlashBlade pricing and cost advice

"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."

"The Price/Performance ratio for this solution is outstanding!"

"The cost, including OPEX, is lower compared to other solutions."

"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 pricing is more than reasonable."

"The pricing is excellent. It will run on anything. You don't have to buy a $100,000 server, with hardware you don't need. You just pay for the license and you're good to go."

"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 setup cost is very low. The pricing is great."

"The free version is great to use for labs or test environments."
