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.

A robust solution with good performance and support

This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

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

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

"The most valuable features of this solution are the rewrite speed and the nonstop services."

"FlashBlade offers low latency, high throughput, and seamless scalability."

"It is very easy to use, and it is very fast."

"The initial setup is pretty quick."

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

"The product is scalable and easy to expand."

"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

"The ease of use is the solution's most valuable aspect. It's very user-friendly."

"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."

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

Cons

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

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

"The features provided for SMB customers are limited."

"I would like to see more deduplication."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"Pure Storage FlashBlade should improve on more cloud integration."

"I would like to see more VM-Aware features in the next release of this solution."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

More Pure Storage FlashBlade cons

"The reporting mechanisms need improvement."

"he interface is not user-friendly so the ease of use could be improved."

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

Pricing and Cost Advice

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

"The price of this solution could be made more affordable."

"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."

"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."

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

"Our customers have seen a reduction in TCO."

"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."

More Pure Storage FlashBlade pricing and cost advice

"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."

"If you are cost-sensitive then this solution is not for you."
