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.

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.

Quotes from Members

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

Pros

"It has absolutely simplified our storage because the dashboards on the consoles show a clear understanding of where you are, and it is also very easy to provision. This been a big help for our teams."

"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."

"The most valuable feature is Safe Mode."

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

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

"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."

"It performs well and it is also very fast."

"The main feature I have found to be product replication."

More Pure Storage FlashBlade pros

"The most valuable feature is the ability to share files across different platforms."

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

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

"Its great servicing high availability. That is what it is used for."

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

"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."

"I rate this product ten out of ten."

"It is incredibly scalable and stable."

More IBM Spectrum Scale pros

"Notable features of Gluster FS include flexibility, scalability, stability, and ease of use."

"The price tag is good compared to the amount of data and high availability provided."

"It's very easy to upgrade storage."

"The technical support team is excellent."

Cons

"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."

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"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."

"I would like to see more VM-Aware features in the next release of this solution."

"The features provided for SMB customers are limited."

"There could be improvements in public cloud integration."

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

"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

"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."

"They should probably simply the Red Hat implementation portion. This portion was not as straightforward as I would like it to be."

"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."

"Integration with other vendors is not available."

"The solution's pricing could be better."

"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."

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

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

More IBM Spectrum Scale cons

"There is a feature in Red Hat’s commercial version that could be beneficial if integrated into the open-source version."

"The performance of the solution must be improved."

"The system should be more intuitive and easier to manage."

"The user interface could be simplified."

Pricing and Cost Advice

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

"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."

"The price could be cheaper."

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

"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."

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

More Pure Storage FlashBlade pricing and cost advice

"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 solution is costly but reliable."

"If you need cheap storage, but still need high availability, it's a good product to look at."

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

Red Hat Gluster Storage (formerly known as Red Hat Storage Server) is a software-defined storage (SDS) platform designed to handle the requirements of traditional file storage—high-capacity tasks like backup and archival as well as high-performance tasks of analytics and virtualization. But unlike traditional storage systems, Red Hat Gluster Storage isn’t rigid and expensive. It easily scales across bare metal, virtual, container, and cloud deployments.
