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.

Quotes from Members

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

Pros

"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."

"The most valuable feature is Safe Mode."

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

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

"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."

"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."

"The initial setup is pretty easy and simple."

"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."

More Pure Storage FlashBlade pros

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"The performance, reliability, and affordability has been most valuable."

"Its technical support is excellent."

"The price performance is the best advantage of Microsoft Storage Spaces Direct."

"The most valuable feature are the caching capabilities using the storage class memory."

"It's mainly about the storage expansion, like in hyper-converged solutions."

"The initial setup is straightforward."

"The flash ability, in terms of tiering and caching, is amazing"

More Microsoft Storage Spaces Direct pros

"It's very easy to upgrade storage."

"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."

"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."

"I would also like to see better support for CIFS workloads."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

"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."

"It usually comes down to just what you hit and the value you're getting when you spend the money and license the products. I would always go, "If you want to make things better, lower your price and make your licensing simpler." There's always an opportunity around that."

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

"The documentational aspect of FlashBlade needs improvement."

"The solution is expensive."

More Pure Storage FlashBlade cons

"Documentation management could be improved"

"More optimization could be done in terms of mirroring."

"The management tool within this solution could be improved. We would also like to be able to access services like Azure when using this solution."

"Microsoft closed the shared cluster support, which is important for the solution."

"I think the online documentation needs a lot of work and so do the sizing tools."

"It is scalable, but only beyond two nodes. If I go for two nodes it's not scalable. I need to build a complete cluster from the beginning if I'm going for two nodes."

"The integration is not difficult because there is no GUI, but we need to use a PowerShell command. This makes it difficult to monitor and to see the components' statuses."

More Microsoft Storage Spaces Direct cons

"The performance of the solution must be improved."

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

"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."

Pricing and Cost Advice

"Our licensing is renewed annually."

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

"The price could be cheaper."

"The price is a little high."

"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."

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

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

More Pure Storage FlashBlade pricing and cost advice

"Cost-wise the product is one of the more affordable within the category of products."

"The solution is expensive."

"With the data center licensing and everything that is connected to that, this solution is relatively costly."

"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

Storage Spaces Direct uses industry-standard servers with local-attached drives to create highly available, highly scalable software-defined storage at a fraction of the cost of traditional SAN or NAS arrays. Its converged or hyper-converged architecture radically simplifies procurement and deployment, while features like caching, storage tiers, and erasure coding, together with the latest hardware innovation like RDMA networking and NVMe drives, deliver unrivaled efficiency and performance.

Microsoft

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.
