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.

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

"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 are the Metro clustering, and disaster recovery."

"The most valuable feature is Safe Mode."

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

"The onboarding and integrated monitoring tools are pretty good."

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

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

More Pure Storage FlashBlade pros

"The support is excellent."

"Continuous data protection (CDP), can be used to "protect" again ransomware by recording all write on disk in a log. You can recover your data with incredible time granularity."

"DataCore has helped provide flexible, highly available, high-performance storage that otherwise would have been outside our price range."

"Good security with this 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."

"I am very happy with this product's ability to adapt, increase, and modify existing infrastructures."

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

More DataCore SANsymphony pros

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

Cons

"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."

"Its configuration should be easier."

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

"The features provided for SMB customers are limited."

"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."

"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."

"File storage needs a lot of improvement. Mainframe connectivity also needs improvement because it requires additional components to be integrated with Pure Storage FlashBlade. If you want to keep your backup data, then this becomes an even more expensive solution because Pure Storage FlashBlade will not be able to meet your backup needs."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

More Pure Storage FlashBlade cons

"I'd like to see the company make the renewal of the software cheaper."

"SANsymphony is missing some features that vSAN has. For example, vSAN has a special feature called continuous data protection. It provides the ability to go back in time to a given moment. You can see what was on your disk in the past up to two weeks. That's a great feature because ransomware attacks are increasingly common, and that provides you some kind of protection."

"The solution could be better packaged and marketed."

"Datacore is developing a new WebUI with new dashboards. It is a good idea as the classic GUI is lacking dashboards."

"DataCore needs a more efficient and better way to keep track of metrics and counters so that we can do baseline analysis to measure performance."

"The cloud reporting interface is quite poor compared to other vendors."

"I still see room for improvement with DataCore SANsymphony in the area of alarm and task management."

"Management could be improved. The management console sometimes reacts very slowly."

More DataCore SANsymphony cons

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

Pricing and Cost Advice

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

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

"Our customers have seen a reduction in TCO."

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

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

"I feel that the price could always be lowered."

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

"Our licensing is renewed annually."

More Pure Storage FlashBlade pricing and cost advice

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

"This solution allows the use of off-the-shelf hardware and charges by the TB of storage."

"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."

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

"The pricing and licensing are better with DataCore."

"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."

"Pricing has improved but it is still expensive."

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