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.

A robust solution with good performance and support

This is a solution that scales well, although I think that we have stabilized in terms of use. With respect to scalability, we have an open question as to whether we will be able to grow into a cloud-based deployment. We don't know in what ways this solution will assist us with the migration, or whether we can still use it for DR. We don't know about the type of backup, be it full, incremental, or otherwise. We are also looking for a cost-savings if we migrate. These are things that we will find out over time. We have about two petabytes of data.

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

"The product is scalable and easy to expand."

"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."

"The performance of FlashBlade is excellent. It does not necessarily leverage the SOS API that some of the newer products leverage, but I found its speed pretty much on par and comparable. It is fast, and it does what it is supposed to do."

"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."

"The initial setup is pretty quick."

"The initial setup is pretty easy and simple."

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

"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."

More Pure Storage FlashBlade pros

"The most valuable feature is the robustness, which is typical of IBM because their software generally just works."

"The ease of use is the solution's most valuable aspect. It's very user-friendly."

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

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

More IBM Spectrum Scale pros

Cons

"Recently, while upgrading the version code, one of the controllers failed. Replacing the controller took between 14 to 20 days."

"Its configuration should be easier."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

"The documentational aspect of FlashBlade needs improvement."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"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."

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

More Pure Storage FlashBlade cons

"he interface is not user-friendly so the ease of use could be improved."

"The reporting mechanisms need improvement."

"Maybe it needs integration with HA."

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

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

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

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

"Integration with other vendors is not available."

"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."

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

More IBM Spectrum Scale cons

Pricing and Cost Advice

"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."

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

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

"I understand that it is competitively priced compared to other brands."

"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."

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

"The price is a little high."

More Pure Storage FlashBlade pricing and cost advice

"If you are cost-sensitive then this solution is not for you."

"For a database, on a yearly basis, we pay approximately $3,500 for licensing fees. The solution is sold as a subscription on a yearly basis so there are no other ancillary costs."

"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 licensing is based on the number of terabytes."

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 Accelerate is a software-defined block storage solution designed for rapid deployment across heterogeneous infrastructure for hybrid cloud and delivering consistent service levels to a dynamic workload mix. It is based on proven grid-architecture, enterprise-scale IBM XIV technology. IBM Spectrum Accelerate can be deployed, including as hyper-converged infrastructure, on any x86 server, on pre-installed third-party appliances or on public cloud infrastructure, and is available as a service on IBM Cloud infrastructure.

IBM

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.
