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.

Robust with good replication and access protection

The solution is constantly evolving. Recently, deduplication and compression have been further improved to meet customer needs, and updates are easily implemented without stopping production. The update assistant checks the state of health before using good practices, during checks that the data is still presented for service continuity, and afterward, if the actions carried out are indeed active. Technical support is truly available even without a production incident. This is really essential right now.

Anil Rahulwar

Storage Engineer at Movate

Offers good features like Fusion and stable product with better customer service

Fusion is the only best feature, but it's a very good feature. Nexenta is a very old product. Nexenta is a well-established product used in the UK, US, India, Dubai, Qatar, and other countries. It is very good. The interface is up to date. Everything is up to date. The OS version was recently upgraded to 5.5 FP3. AI features: DataDirect Networks owns Nexenta and has won awards for AI. They continuously work on AI features. DDN also has a product called Tintri Infinia with AI features. And NVIDIA product also has AI features. I look forward to working on those products.

Quotes from Members

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

Pros

"It performs well and it is also very fast."

"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."

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

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

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"The main feature I have found to be product replication."

"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."

"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."

More Pure Storage FlashBlade pros

"The dashboard is very intuitive, and there are many counters to diagnose what happens during a short period (like when a backup is in progress)."

"The use of the RAM cache allows you to speed up the writing and reading of data while also allowing for a possible increase in performance by increasing the RAM on the servers."

"DataCore's ability to seamlessly move virtual volume data between storage pools as well as their synchronous mirroring has made maintenance and disaster recovery planning achievable."

"It is a stable solution."

"It allows data to be available from two DataCore servers."

"The most useful feature of SANsymphony is that it's able to manage any brand of block storage."

"It is a very stable solution."

"CDP is an important feature for avoiding data loss in the event of ransomware attacks. You need more storage capacity, however, you get the possibility to return at any time and use the data saved up to that point. The recovery is much faster than with a classic restore."

More DataCore SANsymphony pros

"It has a feature called Fusion that makes it more secure and productive."

Cons

"Its configuration should be easier."

"I want efficiency. FlashBlade doesn't have efficiency now."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"It's on the expensive side, as expected for a niche product."

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

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

"I would like to see more monitoring capability included in the next release of this solution."

"The feature that we're waiting on is better integration with the cell services."

More Pure Storage FlashBlade cons

"Problem detection could be easier. It should help customers identify problems very quickly because it's not easy to analyze on the platform today."

"The solution is constantly evolving."

"It would be ideal if they were providing archive licensing with the ability to create a second pool on existing storage nodes."

"There is room for improvement in the graphical interface."

"One limitation of this solution is that it's Windows-based, e.g. one requirement to install DataCore SANsymphony SDS is putting it on a Windows server machine. It relies on Windows and that is a limitation because there are some customers who are looking for non Windows systems."

"I would like to see reporting added, such as a monthly connectivity report."

"Its interface could be better."

"The graphical interface is not always very stable."

More DataCore SANsymphony cons

"There were some SMB issues, but they were resolved."

Pricing and Cost Advice

"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."

"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."

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

"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."

"Licensing fees are paid yearly."

"The price could be cheaper."

"Our customers have seen a reduction in TCO."

More Pure Storage FlashBlade pricing and cost advice

"Make sure you are made aware of the annual subscription cost when purchasing."

"Pricing has improved but it is still expensive."

"The cost is at the same level as other storage solutions and it is easy to understand the licensing."

"The pricing and licensing are better with DataCore."

"This product has a good ratio between quality and price. In many cases, it's less expensive to work with DataCore than other storage systems."

"In my case, the licensing per terabytes is very high and it must be licensed for each extra functionality."

"We have licensing costs on a yearly basis. They charge per terabyte, so in terms of cost, it can be very costly. They have three different features, and you have to pay extra for those."

"It is relatively expensive, and the additional costs for hardware and storage can make it a significant investment for customers."
