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.

Built-in compression enhances data management efficiency

I have noticed that the technical support for software issues, such as with Spectrum Protect, needs improvement. The case logging process is efficient, but resolving software problems takes too much time. This delay can hinder customers and strain vendor relationships. For hardware issues, IBM handles them efficiently, but software-related support requires enhancement. Overall improvement in support for software cases is necessary.

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

"Speed and ease of use are the two most valuable features."

"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."

"I would rate this solution an eight plus. It has has good flexibility and stability, it's easy to manage and the response time is good."

"We have seen a reduction in the total cost of ownership by around 20%."

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

"Using this solution has made our backups more reliable."

"It's very easy-to-use."

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

More Pure Storage FlashBlade pros

"The ability to add the virtual machine on the Spectrum environment to sort out the data movers(DMs) and their schedules is a valuable feature. You are able to have, for example, four data movers to balance them so you do not have too much work on one data mover."

"When we add storage behind it, the product is good for the customers because their customers do not notice that anything is happening due to the virtualization."

"It provides transparency, because of its advanced copy features."

"The most valuable feature is its reliability."

"The scalability is very good. It can handle anywhere from very small to large enterprise class."

"We are happy with the support that IBM provides us."

"It has the ability to seamlessly move hardware in and out as we refresh technology."

"I like that it can virtualize more than three hundred storage providers."

More IBM Spectrum Virtualize pros

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

Cons

"I would like to see the licensing fees improved as well as the price per terabytes."

"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."

"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."

"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."

"The documentational aspect of FlashBlade needs improvement."

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

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

"I would like to see better integration."

More Pure Storage FlashBlade cons

"I would like to see them provide a unified platform that offers block, file, and object-based protocol access."

"I hate I/O groups. If you start swapping I/O groups, they can be potentially risky. If they could get rid of the whole I/O group principle, the risk is not there anymore. I understand the fundamental thing about I/O groups, but they are risky."

"The case logging process is efficient, but resolving software problems takes too much time."

"In general, the migration is complicated. Though, it is case-by-case."

"I would like to see more baseline replication and integration with the operating system between Vmware and IBMI."

"NBME support and support for a higher Fibre Channel lengths could be improved, but those are already on the roadmap."

"Adding features for data deduplication is one area of improvement."

"They are actually working on one bug we found, which was with flash restore. This was the user interface design for virtual environments."

More IBM Spectrum Virtualize 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."

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

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

"The price is a little high."

"Licensing fees are paid yearly."

"Our customers have seen a reduction in TCO."

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

"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."

More Pure Storage FlashBlade pricing and cost advice

"I am very happy with the pricing. There is no comparison when it comes to pricing. I have looked at all solutions from EMC, Veritas, Hitachi, Dell, etc. None of them compares to IBM when it comes to pricing. I get great pricing from them."

"This solution came as an additional cost for the TSM package we chose."

"I think it is a good value for the price."

"We have struggled with Pure Storage, but people are understanding that much of Pure has been consumer grade SSDs. Therefore, when the customer is really understands what they are getting, they realize that IBM presents the same sort of value as existing vendors."

"Generally the bundled licensing is more cost effective and gives flexibility to the solution. Linking into the Spectrum Suite can also be advantageous, but depends on the scale of the enterprise."

"We would like the CPU cycle to save more on the licensing costs for us."

"It has a lot of advanced functions for a reasonable price."

"The entry point of pricing for this product is the most amazing price ever in the industry."
