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.

"It is incredibly scalable and stable."

"I rate this product ten out of ten."

"I would rate my overall experience with IBM Spectrum Scale as nine out of ten."

"GPFS monitoring is the best feature."

More IBM Spectrum Scale pros

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

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

"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."

"The SVC gives excellent performance with tiered storage behind it."

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

More IBM Spectrum Virtualize pros

Cons

"The solution is expensive."

"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."

"It would be nice if you could store file-based in the same box with the same technology."

"The documentational aspect of FlashBlade needs improvement."

"The features provided for SMB customers are limited."

"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."

"The speed could be improved."

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

More Pure Storage FlashBlade cons

"The pricing and licensing model for this solution are complex and it is sometimes difficult to explain it to customers."

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

"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."

"It would be helpful if there was a graphical user interface that could walk you through the deployment process. The instructions surrounding setup aren't the best. They need to be more step-by-step."

"Maybe it needs integration with HA."

"The biggest problem is that it is not able to provide block storage."

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

"There can be improvements in fault tolerance and making erasure coding faster."

More IBM Spectrum Scale cons

"t is limited in terms of a single system to eight nodes or four, what they call IO groups."

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

"The disk reliability is not that good."

"I already discussed possible improvements with some of the guys from Hearnsley. One of our frustrations is when you go to expand volumes in a global mirror environment, you have to stop everything in order to expand. So that's one of the things."

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

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

"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."

More IBM Spectrum Virtualize cons

Pricing and Cost Advice

"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."

"Our licensing is renewed annually."

"We used a reseller for the purchase."

"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."

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

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

"Our customers have seen a reduction in TCO."

More Pure Storage FlashBlade pricing and cost advice

"The solution is costly but reliable."

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

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

"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."

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

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

"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."

"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."

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.
