Has handled backup storage needs reliably and supports seamless upgrades

In environments requiring high throughput and low latency, Pure Storage FlashBlade provides high throughput and normal latency, but we do not have any application that requires low latency right now, so the latency of three to five milliseconds is considered kind of high. Pure Storage FlashBlade's ability to integrate with enterprise applications is not important for us, as we only want to present an S3 bucket for our backup, which we have done, and it works very fast. We use the Purity software's data reduction techniques; we have a backup software that compresses everything before sending it to the S3 bucket, achieving a data reduction of 1.1 to one. I would recommend Pure Storage FlashBlade to other companies because it's a very fast and scalable solution for anyone who needs it. On a scale of 1-10, I rate this solution an 8.

Flexibility and reliability have supported seamless data growth

I cannot think of anything to improve about Dell PowerScale (Isilon). The hardest challenge we have is due to how we've bought things over time. The way that we moved to the PowerEdge platform for the newer systems creates a scale problem as I still buy the older style systems, which are more dense storage. They're different chassis, so the problem we run into in the data center is the depth of the actual equipment. The newer equipment, if we buy an FX910 or a 900, it's a lot shorter in scale than if I buy an 83,000, which is much bigger. This makes it more complicated for deployment.

OpEx storage model has simplified SLAs, capacity planning, and cyber‑resilient recovery

The most valuable features in Pure Storage Evergreen One are the SLAs, which are tied to the kind of services that we are going to run. These SLAs govern the consumption and the reporting as well. I find it more attractive when we are tied to a specific SLA, and the VRA is providing the services within that agreed SLA, then there is no requirement for a complete capacity assessment. The entire capacity review, assessment, and recommendations come as part of Pure Storage Evergreen One solution. Pure Storage Evergreen One has a list of services which will provide the services, including cyber resilience. First, they have complete capacity management which is done by them and which will also provide us a heads up on how we are consuming the services and where these services can be improved. Second, it will also provide us some of the key attributes, such as we can take the snapshots and LUN snapshots, which will provide a cyber-resilient copy where data can be secured in case of a cyber attack. We have an option to basically recover the earliest. Third, because of this feature and because of Pure Storage Evergreen One, I am talking about the Evergreen aspect. Because of Evergreen, we also have an option to upgrade the controllers based on the SLAs. If the agreed SLAs are not meeting the requirement, we have a provision to upgrade the controllers and so on. This is giving a good feature for us to evaluate and provide a valuable proposition to the customer who wants to use Pure Storage as a Pure OpEx model.

Quotes from Members

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

Pros

"What I like best about Pure Storage FlashBlade is its object storage functionality, plus it has fast underlying hardware. Pure Storage FlashBlade is also very stable. I find its stability one of its valuable features."

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

"Pure Storage FlashBlade's scalability is one of the most valuable features, and importantly, it always works, allowing for seamless upgrades."

"The most valuable feature is Safe Mode."

"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."

"It's very easy-to-use."

"The initial setup is pretty quick."

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

More Pure Storage FlashBlade pros

"It has allowed us to have more consistent quality controls. It has also allowed us to expand the number of servers in clients processing and accessing data, allowing us to get a lot bigger projects out the door."

"Customer service is absolutely satisfying, rating at least nine out of ten, as they have managed previous issues well."

"Dell PowerScale's performance is good."

"The most valuable feature of Dell PowerScale is its scalability."

"Dell PowerScale (Isilon) definitely deserves ten out of ten for scalability."

"Dell PowerScale (Isilon) is brilliant for scalability and really, really good in that regard."

"Dell PowerScale (Isilon) is a platform that is very easy for teams to work with."

"You plug in a new node and data starts migrating over to it, and IT spreads out the load. We've added multiple nodes to the system since deploying it. The process is pretty seamless, and we are able to do it with no downtime. It's a very easy process to do."

More Dell PowerScale (Isilon) pros

"The speed of the product is quite a bit better in performance than the previous peer environment we were running on, and it seems to have a better feature set."

"The most valuable features in Pure Storage Evergreen One are the SLAs, which are tied to the kind of services that we are going to run, and these SLAs govern the consumption and the reporting as well."

"We have snapshots. We put snapshots on disks, and we can save information. In the case of ransomware, everything is in the snapshot. We have a snapshot lock on it, so it's safe."

"Pure Storage has the highest Net Promoter Score in the market."

"The speed of the product is quite a bit better in performance than the previous environment we were running on, and it seems to have a better feature set."

"The Evergreen program is excellent, and the pricing is quite reasonable. My friends who work there are doing very well and consistently achieving strong results. Like any company, they experience occasional downturns but perform impressively overall."

Cons

"There could be improvements in public cloud integration."

"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."

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

"Its configuration should be easier."

"In terms of scalability, it doesn't expand out quite as robustly as some of the others, but it covers 90% of the market in what it does."

"In my opinion, one way Pure Storage FlashBlade can be improved is by having more compatibility between the FlashArray and FlashBlade, allowing for synchronized data between both platforms."

"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."

"The features provided for SMB customers are limited."

More Pure Storage FlashBlade cons

"The price always has room for improvement."

"It would be nice to see tools like Superna Eyeglass built into PowerScale."

"There is room for improvement with the updates. It can take a significant amount of time to do a major OS update. However, even though it takes multiple reboots, the cluster stays up. If we want to apply a newer version of the OS, we have to roll back some of the patches so that we can upgrade. It requires a few reboots just to do that. The cluster doesn't come down, everything is still running, but it's time-consuming, at times."

"The tool's support team and the way the cases are handled by the product's technical support team are both areas of concern where improvements are required."

"Improvements could be made to reduce the costs and the high level of knowledge needed to maintain and use them."

"Perhaps if there was a local chatbot built within the system or on the dashboard where we could directly ask for anything on the OneFS, it could help us."

"The product itself is capable of very much, but the initial deployment experience can be lacking possibly because it does not incorporate any design phase."

"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."

More Dell PowerScale (Isilon) cons

"It would be nice to have support in Swedish."

"Many customers report that the starting price is quite high. However, the overall total cost of ownership can be reduced over time due to features like the Evergreen architecture, which allows savings through less management and environmental benefits."

"The only potential drawback is that Pure Storage might be overkill if you don't need microsecond response times."

"To me, I think it's a little expensive. Then again, you get what you pay for."

"I'm not sure if any improvements are needed."

"I would love to explore more options on what Pure Storage Evergreen One can offer in general, mostly from the cybersecurity perspective and air gap."

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."

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

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

"Our customers have seen a reduction in TCO."

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

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

"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."

More Pure Storage FlashBlade pricing and cost advice

"Price was also a significant factor in our decision to go with PowerScale. The team at EMC, now Dell EMC, came through with a highly competitive offer that tipped the scales towards their solution. There was only one other solution around the same price point, but it could not match PowerScale on features. That other solution is no longer on the market."

"The pricing is expensive, but I think it's a fair value because it does manage itself. It definitely is much simpler than any of the other scale-out storage platforms that we've looked at in the past."

"Pricing for this solution is reasonable."

"The price of the solution is high."

"It is an expensive product with a high storage capacity suitable for large data requirements."

"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."

"It is an expensive solution."

"The price of Dell PowerScale (Isilon) is reasonable."
