High performance and throughput enhance IT backup management

The multi-dimensional scale-out design feature of Pure Storage FlashBlade is not in use in our environment. Regarding data reduction technologies, we don't get much deduplication because the data is already deduplicated from our FlashArray before we get to backup, so there is no benefit of deduplication. Regarding the integration with cloud-native ecosystem tools, we are not on cloud; we are strictly an on-premises solution. Pure Storage FlashBlade is not used by any end-user; it's used only for IT backup, with only about four people in our group managing it. I cannot recommend Pure Storage FlashBlade to other users depending upon their financial situation because it's an expensive solution, and the cost is very high, including licensing and renewal every year. I rate Pure Storage FlashBlade an eight out of ten.

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.

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

"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 features are the Metro clustering, and disaster recovery."

"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."

"It uses the same platform for connectivity so integration is seamless."

"The snapshots, replication, and the ability to have immutable blades are the most valuable features. You're putting data snapshots out in those blades, and they cannot be touched. Its performance is great."

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

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

"The solution provides many controllers."

More Pure Storage FlashBlade pros

"It is incredibly scalable and stable."

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

"I find IBM Spectrum Scale to be an excellent product known for its fast parallel file system."

"We are using it for monitoring all of our storage."

"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."

"GPFS monitoring is the best feature."

"The profile share is a valuable feature."

More IBM Spectrum Scale pros

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

"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."

"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 solution is user-friendly."

"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."

"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 monitoring capability included in the next release of this solution."

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

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

"The features provided for SMB customers are limited."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"I would like to see more deduplication."

"On our dedupe during our initial buy, we were expecting a number a little higher like 4x. However, we are getting about 3.6. While it is close enough, it doesn't quite hit the numbers. So, this has been a challenge."

"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."

More Pure Storage FlashBlade cons

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

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

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

"The main issue that we have now is with the encryption. They want to use more metrics in encryption, which is not working very well."

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

"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."

More IBM Spectrum Scale cons

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

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

"The integration has room for improvement."

"The documentation could be better."

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

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

Pricing and Cost Advice

"The product is very expensive."

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

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

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

"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."

"We used a reseller for the purchase."

"Support is a separate line item. Support is a different cost, but whatever your support is now, that's what you're going to pay forever. If your support's $100 today, six years from now it's $100. It doesn't fluctuate unless you upgrade it, or change it, etc."

"Our customers have seen a reduction in TCO."

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."

"The price of Portworx Enterprise is high."

"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 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."

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

Portworx is the solution for running stateful containers in production, designed with DevOps in mind.
