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.

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.

Consultant at PBOservicos-Informatica

A solution backed by strong customer support, that is stable and scalable

As a company managed in a Kubernetes environment, being trusted by a Kubernetes vendor, Red Hat creates barriers against using other certified solutions that work. Because IBM is a competitor of Pure Storage, things seem to be getting worse. I don't have plans to use Portworx Enterprise in the future because, at the moment, I am working with Ondat, and I have to follow NetApp's direction on that. When evaluating Portworx, one should make sure their company has already chosen Pure Storage. Still, if they are evaluating the solution on Ondat or Dell or other platforms, they should get a roadmap statement from Pure Storage, that they will continue to develop storage hardware diagnostics. I rate Portworx a nine out of ten.

Quotes from Members

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

Pros

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

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

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

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

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

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

"The solution provides many controllers."

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

More Pure Storage FlashBlade pros

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

"The profile share is a valuable feature."

"It is a scalable solution."

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

"It is incredibly scalable and stable."

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

"GPFS monitoring is the best feature."

"We can have multiple systems within the same file system."

More IBM Spectrum Scale pros

"The solution is user-friendly."

"Portworx is a simple solution. It's similar to Pure Storage products. They're all easy to use and install. You need to have a little expertise with containers to use Portworx, but it will be no problem for you if you understand containers."

"The best thing about Portworx is the Stork, they have called the VPS (Volume Replacement Strategy) and they also have topology awareness, and these are the three features I like."

"Portworx virtualizes the aspects of the underlying block storage. That is good because they can also use block storage for their future deployment instead of just NFS."

"I like that you have a small dedicated file system that is fast and resilient for containerized workloads."

"A custom IBM script is designed to tackle the storage management challenges within containerized environments, providing crucial data services and features required for enterprise applications."

Cons

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

"The features provided for SMB customers are limited."

"It's on the expensive side, as expected for a niche product."

"They need better integration with public clouds along with a better hybrid solution."

"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 deduplication."

"The solution is expensive."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

More Pure Storage FlashBlade cons

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

"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."

"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."

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

"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."

"Integration with other vendors is not available."

"Maybe it needs integration with HA."

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

More IBM Spectrum Scale cons

"The integration has room for improvement."

"They have not integrated Portworx with Ondat since they are too focused now on Pure Storage APIs and not on users like us."

"I think the vendor could provide more training for new users who may not be familiar with containers."

"The documentation could be better."

"I would like to see a more native mapping to mainframe-type systems."

"It would be highly advantageous to include an integrated backup solution within the same license, rather than purchasing backup separately."

Pricing and Cost Advice

"The pricing for FlashBlade is between cheap and moderate."

"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."

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

"We used a reseller for the purchase."

"The price is a little high."

"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."

"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

"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."

"The price is competitive, but it is too expensive when paired with Red Hat IBM."

"It has two offerings. One is free, which is limited to only five nodes. The other is enterprise, which is a bit pricier."

"I'm not sure how the licensing was broken out, but I don't think our offering of the Portworx was more than USD $20,000."

"The price of Portworx Enterprise is high."

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
