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.

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 initial setup is pretty quick."

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

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

"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 initial setup is pretty easy and simple."

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

"FlashBlade offers low latency, high throughput, and seamless scalability."

More Pure Storage FlashBlade pros

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

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

"Its technical support is excellent."

"The main positive impact that Microsoft Storage Spaces Direct has had on my company over the years is increasing performance; our checks show it is three times faster than VMware, making us extremely happy and motivated to keep using it."

"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"

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

More Microsoft Storage Spaces Direct pros

"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."

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

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

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

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

Cons

"I would like to see better integration."

"I want efficiency. FlashBlade doesn't have efficiency now."

"The speed could be improved."

"An area for improvement in Pure Storage FlashBlade is its price. It could be reduced. The technical support for Pure Storage FlashBlade also needs improvement. It used to be good, with more experienced engineers. Nowadays, it isn't, and it takes longer for support to solve problems."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"There is some room for new features related to authentication and integration with Kubernetes, and other solution using S3 Bucket."

"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 documentational aspect of FlashBlade needs improvement."

More Pure Storage FlashBlade cons

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

"On a scale of one to ten, I would rate the customer service and technical support of Microsoft Storage Spaces Direct a three, as there were issues that the Microsoft team could not pinpoint, leading to delays in finding solutions."

"Documentation management could be improved"

"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 optimization could be done in terms of mirroring."

More Microsoft Storage Spaces Direct cons

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

"I'd like to see improved hardware compatibility"

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

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

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

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

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

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

Pricing and Cost Advice

"The price could be cheaper."

"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."

"We used a reseller for the purchase."

"The price is a little high."

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

"Our licensing is renewed annually."

"Our customers have seen a reduction in TCO."

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

More Pure Storage FlashBlade pricing and cost advice

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

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

"The solution is 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 solution is very 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 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.
