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.

Quotes from Members

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

Pros

"It has also helped to simplify storage for us in the way that it's easy to manage. Their automatic monitoring really helps when things break or are about to break. They see a problem coming and alert us even before our own system does."

"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."

"We have seen a reduction in the total cost of ownership by around 20%."

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

"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."

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

"Using this solution has made our backups more reliable."

"The most valuable feature is Safe Mode."

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."

"It's very easy to upgrade storage."

"The technical support team is excellent."

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

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

Cons

"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."

"The speed could be improved."

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

"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."

"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 have Snapshots and Snapmail in the next release. People who came from a NetApp background, especially expect these features."

"I would like to see the licensing fees improved as well as the price per terabytes."

"I would like to see better integration."

More Pure Storage FlashBlade cons

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

"The reporting mechanisms need improvement."

"The user interface could be simplified."

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

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

"The performance of the solution must be improved."

Pricing and Cost Advice

"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."

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

"Licensing fees are paid yearly."

"Our customers have seen a reduction in TCO."

"Our licensing is renewed annually."

"The price could be cheaper."

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

"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

"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."

"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 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

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.
