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.

Deliver improved performance in data processing and foster extensive AI initiatives

I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system. It achieved the best results when integrated with IBM hardware. Even though it is complex, it provided significant performance advantages in large-scale data management. Its fault tolerance mechanisms and integration capabilities make it popular for extensive AI initiatives and data processing tasks for organizations like Daimler Benz and Bosch.

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 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 Pure Storage FlashBlade a ten out of ten."

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."

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

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

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

"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."

More Pure Storage FlashBlade pros

"The high performance of the solution is its most valuable aspect. If you compare it to other storage solutions, it's much better."

"It is incredibly scalable and stable."

"It has been pretty reliable throughout the years. As far as capacity is concerned, it can handle most heavy loads."

"It makes our file system sharing a lot easier, even across different continents. We have had file systems shared across different continents with no performance degradation."

"The profile share is a valuable feature."

"I rate this product ten out of ten."

"Technical support has been very helpful. They provide us with pretty good solutions that we can implement moving forward."

"We use GPFS Scale for parallel file access, the file management, and it's an essential part of our operations."

More IBM Spectrum Scale pros

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

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

"The abstraction flair and the abstraction layer. We had a mixture of different storage arrays, and the wonderful thing about SVC is is that it normalizes all it into a single driver. A single view that all hosts see simultaneously."

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

"Although the GUI from the XIV was used (in my view), IBM has polished and refined the GUI providing a pleasant and easy to navigate GUI experience."

"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."

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

"It's got full features, so we can compress volumes. We can do thin volumes and we can change them on the fly."

More IBM Spectrum Virtualize pros

Cons

"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."

"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."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

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

"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 more VM-Aware features in the next release of this solution."

"There could be improvements in public cloud integration."

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

More Pure Storage FlashBlade cons

"The initial setup is complex, especially if trying to avoid erasure coding, as it requires more discs. Avoiding erasure coding can significantly increase costs."

"I believe there is no graphic user interface, so they should include it."

"Integration with other vendors is not available."

"I wish there were some graphical user interface to access the GPFS file system creation and monitoring."

"This is probably the biggest challenge, getting everything upgraded, because it just takes time. We wish it was a faster solution to be able to do everything at once, but you have do each node individually. The more nodes, the longer it takes."

"Making it a little easier to add bad file sets would help. There is a transition to how you add storage and how you add a file set, so making that a little smoother would probably be my recommendation."

"We do have some issues where Spectrum Scale does not work as expected. We have seen our Spectrum Scale servers go down unexpectedly, but because we have a cluster, it does not take out the entire organization."

"Maybe it needs integration with HA."

More IBM Spectrum Scale cons

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

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

"Tighter integration with cloud storage might be useful as a target for a variety of use cases."

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

"The training program could be improved."

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

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

"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

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

"The product is very expensive."

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

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

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

"Licensing fees are paid yearly."

"The price is a little high."

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

More Pure Storage FlashBlade pricing and cost advice

"The licensing is based on the number of terabytes."

"The licensing model is complex and depends on factors such as the number of processing cores and the amount of storage."

"The solution is costly but reliable."

"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."

"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."

"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."

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

Overview

FlashBlade is the industry’s most advanced scale-out storage for unstructured data, powered by a modern, massively parallel architecture to consolidate complex data silos (like backup appliances and data lakes) and accelerate tomorrow’s discoveries and insights.

Pure Storage

IBM Spectrum Scale is a cluster file system that provides concurrent access to a single file system or set of file systems from multiple nodes. The nodes can be SAN attached, network attached, a mixture of SAN attached and network attached, or in a shared nothing cluster configuration. This enables access to this common set of data to support a scale-out solution or to provide a high availability platform. IBM Spectrum Scale has many features beyond common data access including data replication, policy based storage management, and multi-site operations. You can create a cluster of AIX nodes, Linux nodes, Windows server nodes, or a mix of all three. IBM Spectrum Scale can run on virtualized instances providing common data access in environments, leverage logical partitioning, or other hypervisors. Multiple IBM Spectrum Scale clusters can share data within a location or across wide area network (WAN) connections.

IBM

IBM Spectrum Virtualize is a dependable solution that improves data value, security, and simplicity for new and existing storage infrastructure. Proven over 12 years in thousands of deployments, its innovative virtualization capabilities help organizations achieve better data economics by supporting new workloads that are critical to their success. IBM Spectrum Virtualize software helps make new and existing storage more effective and standardizes functions traditionally deployed separately in disk systems for greater flexibility and potentially lower costs.
