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.

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.

Quotes from Members

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

Pros

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

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."

"The most valuable feature is Safe Mode."

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

"I would rate Pure Storage FlashBlade a ten out of ten."

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

"The product is scalable and easy to expand."

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."

"The ease of management, the simplicity of the CLI, the speed of that interface, and the well-architected design of the product in general are valuable features."

"The biggest benefits of IBM Spectrum Virtualize are its stability, data security, and customer support."

"We acquire companies (and things), so we end up with odd hardware. We bring it behind the SVC and it allows us to migrate stuff off of it seamlessly. SVC can also cover up a host of defects of the underlying storage."

"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."

"Using SBC, a valuable feature is the mirroring, which is the virtualization of the disk between disparate places."

"Migration from configurations where servers have storage provisioned from older SAN disk systems to newer storage systems is almost seamless using image mode migration techniques, with only a short outage of the servers."

"The ability to have a feature-rich software set which extends the capabilities of the back-end storage arrays."

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

More IBM Spectrum Virtualize pros

Cons

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

"The features provided for SMB customers are limited."

"There could be improvements in public cloud integration."

"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 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."

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

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

More Pure Storage FlashBlade cons

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

"The reporting mechanisms need improvement."

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

"Level 1 technical support needs improvement."

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

"The integration would be an option that we would like, but I understand that's not how it's going to be implemented."

"GUI should be developed in HTML5 as opposed to Java."

"For improvement considerations, I would probably say multiple sites."

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

"There are big arrays now, and if a customer wants add more disks to it, you have to have another array. Adding disks to existing arrays is one of the most demanded things from our customers."

Pricing and Cost Advice

"Licensing fees are paid yearly."

"The price could be cheaper."

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

"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."

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

"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."

"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."

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."

"Do a proof of concept, if you are not comfortable jumping in, but do it."

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

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

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

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

"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."

"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."

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