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.

Good performance and reliable but the setup is complex

We would like to see a self-sufficient installation. Nowadays it's open-source, but the installation is still tied to the vendor, which means it is unlikely that it is going to scale. I want them to tap into the broader community. It is really emerging, they have a year over year, 50% annual growth. With a 10-year-old company, it will certainly bring a lot of interest, and will certainly make it more successful, if they tap into that growing customer base. They have to make themselves relevant to the industry. The industry is totally geared to the Cloud, DevOps, and geared for agility. The software with the appliance in my set is already outdated, and it is not that it cannot sell, but it has to be tapping into the emerging and growing sectors to continue with the customers and businesses. This is what the requirement is, to improve their technology. Which means that they have to make themselves relevant to the industry.

Stability-wise, a device that has been up and running for years

The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

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

"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."

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

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

"The initial setup is pretty quick."

"Among its most appealing features are its ease of handling and minimal maintenance requirements."

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

"The ease of deployment and management has helped us simplify our storage. We also do not have to worry about capacity management as much. A lot of these things are native to Pure Storage."

More Pure Storage FlashBlade pros

"The technology is stable which is good."

"Workflow is easy to manage and maintain."

"This has been one of the most reliable storage systems that I have ever used."

"The solution is useful for machine learning and scientific applications, including computer simulations."

Cons

"There could be improvements in public cloud integration."

"In terms of technical support, the experience has been mixed. The support is done through email and is not that great, making it a very problematic area I've been dealing with for over four years."

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

"The solution is expensive."

"I would like to see more deduplication."

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

"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."

"The features provided for SMB customers are limited."

More Pure Storage FlashBlade cons

"We would like to see a self-sufficient installation."

"Lacks some ability to integrate with different systems."

"The write performance could be improved because it is less than half of the read performance."

"The read/write ratio is an area in the solution with some flaws and needs improvement."

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."

"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."

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

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

"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."

"Our licensing is renewed annually."

"I feel that the price could always be lowered."

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

More Pure Storage FlashBlade pricing and cost advice

"Quantum ActiveScale is open-source."

"We acquired VAST Data as a one-time, capital purchase."

"Price-wise, VAST Data is not the cheapest, not the most expensive one."
