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

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

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

"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 tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

"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."

"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."

"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 is very easy to use, and it is very fast."

More Pure Storage FlashBlade pros

"The most valuable feature is that there is no single point of failure."

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

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

"The initial setup is straightforward."

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

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

"Its technical support is excellent."

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

More Microsoft Storage Spaces Direct pros

"This is an easy-to-use product for adding flexibility to your storage solution."

"VMware Software Defined Storage gives higher availability against data corruption."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"The single management panel is the main feature that is wonderful for the customer."

"The best part of the solution is that you can actually scale up to a large number of operating systems without additional hardware."

"The solution is simple to configure and provides good performance and less footprint."

"The most valuable features of VMware Software Defined Storage are scalability, high availability, and performance."

"The most valuable features of the solution are that it is easy to deploy and the support is really good."

Cons

"Its configuration should be easier."

"The feature that we're waiting on is better integration with the cell services."

"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."

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

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

"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."

"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."

"We initially encountered challenges with the assembly process due to issues with the documentation required during setup, an area where Pure Storage needs improvement."

More Pure Storage FlashBlade cons

"It is difficult to get a hardware compatibility certification for the 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."

"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."

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

"Documentation management could be improved"

"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."

"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."

More Microsoft Storage Spaces Direct cons

"The solution has some limitations in terms of replication to remote sites or cloud infrastructure, which need improvement."

"The performance is not as good as some competing products and reporting can be improved."

"VMware Software Defined Storage should include a shared database on a standard version."

"I'd like to see improved hardware compatibility"

"There is room for more integrations and plugins into more storages."

"It doesn't have the ability to be deployed on any kind of hardware and network connectors."

"The license model of the product is an area of concern where improvements are required."

"Simplifying the licensing model and making it cheaper would improve the solution."

Pricing and Cost Advice

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"Our licensing is renewed annually."

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

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

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

"The product is very expensive."

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

"The price is a little high."

More Pure Storage FlashBlade pricing and cost advice

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

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

"The solution is expensive."

"A single socket costs you around US $6,000 for three years. At a minimum, you have a three load cluster for a medium or enterprise-scale company. It can get quite expensive because you're likely to need four to six sockets on the other side. It comes to around $30,000."

"The solution is very expensive."

"I believe there is a yearly licensing fee of around $2000 - $5000. I don't think there are additional costs above that but it depends on the type of infrastructure you're booting."

"The product is quite expensive and is among the most expensive for this type of solution."

"VMware Software Defined Storage is a slightly expensive solution."

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

VMware software-defined storage is a simple, yet intelligent, storage data center architecture that aligns with business and application demands—eliminating static, purpose-built and inefficient hardware with dynamic, agile and automated solutions.
