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

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

"The main feature I have found to be product replication."

"It performs well and it is also very fast."

"We have integrated it with VMware. The integration process is pretty good. Especially with VMware, it helps with the capacity of it."

"The tool's most valuable feature is its fast performance, especially in handling snapshots. It helps during power outages when we need to quickly move data between different data centers. It ensures efficient replication and helps maintain our data centers' uptime."

"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 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."

More Pure Storage FlashBlade pros

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

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

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

"The initial setup is straightforward."

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

"Its technical support is excellent."

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

More Microsoft Storage Spaces Direct pros

"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."

"It's very easy to upgrade storage."

"The technical support team is excellent."

Cons

"The solution is expensive."

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

"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."

"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."

"I have not seen ROI."

"There could be improvements in public cloud integration."

"I would like to see more monitoring capability included in the next release of this solution."

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

More Pure Storage FlashBlade cons

"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."

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

"There is a lot of room for improvement. I would like to have more tools to monitor the function and problems."

"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."

"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."

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

More Microsoft Storage Spaces Direct cons

"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

"Licensing fees are paid yearly."

"The price is a little high."

"We used a reseller for the purchase."

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

"The price could be cheaper."

"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."

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

"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

"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."

"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.
