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.

Quotes from Members

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

Pros

"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 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."

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

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

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

"The initial setup is pretty quick."

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

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

More Pure Storage FlashBlade pros

"PowerScale helped free up our employees' time to focus on other business priorities. There are now automated jobs such as backing up and replicating data, that reduce the footprint we have. Those types of tasks were previously done manually."

"The solution allows me to use SSMDS to store data for end users and share it within different locations."

"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."

"Since it can scale so easily, as long as I have money to buy more nodes, I can grow it as big as I need to. That is important in our business. As sequencing technologies continue to evolve, and as those technologies evolve, the amount of data generation never gets smaller. It just always seems to get bigger. This is one of the absolute key aspects: We can grow on demand without having to forklift stuff."

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

"I assess the stability and reliability of Dell PowerScale (Isilon) as perfect, as we haven't had any hiccups with it so far."

"Certainly, we have seen return on investment and peace of mind, especially with our two clusters that are linked together, where one is a disaster recovery solution for the other."

"This has been a valuable solution for our business overall. It offers business continuity and replication features."

More Dell PowerScale (Isilon) pros

"Huawei FusionStorage does well in its basic functions and offers broad utility."

"Provides easy access to our data."

"It is a stable solution."

"The solution’s most valuable feature is its performance."

"In cases where system interruptions occur, it enables rapid restoration, ensuring a prompt return to normal service levels."

"The product has a very simple GUI-based management platform and it is very simple to use. There is a very easy step-by-step configuration procedure that guides you through, and you can configure it very easily."

Cons

"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 speed could be improved."

"I would like to see more VM-Aware features in the next release of this solution."

"I would like to see more deduplication."

"Its configuration should be easier."

"Pure Storage FlashBlade should improve on more cloud integration."

"To improve FlashBlade, some analysts suggest enhancing its handling of relational database management systems and SQL queries."

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

More Pure Storage FlashBlade cons

"If they integrated some functions, as they have on Data Domain with a cyber recovery vault, it would be ideal."

"We're still fairly new with it. It's been a pretty positive experience thus far. However, they could improve implementation, as we had to rack and stack it ourselves."

"My experience with customer service and technical support has been challenging. The reason is that it is difficult to find subject matter experts around the solution."

"Dell PowerScale can improve on its multi-tenant part because as a service provider, we have bigger clusters in data centers where we can serve multiple customers and grant them dedicated management points and automation features that can be managed in a multi-tenant environment."

"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."

"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."

"It would be good to have synchronized mirroring between two clusters without using a third-party program."

"The solution can be a bit complex for those not well versed in the technology."

More Dell PowerScale (Isilon) cons

"The problem with Huawei is that it generally oversells. As a principle, Huawei does not educate the partner or the end user enough to scale up their solution correctly."

"The product needs improvement in terms of affordability."

"I hope for improvements in the product's processing ability and performance."

"The initial setup and installation is not that straightforward. It should be made easier and the time to install should be reduced."

"The solution’s support could be improved."

"Their cloud services could be improved."

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"We used a reseller for the purchase."

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

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

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

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

"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

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

"Dell PowerScale is expensive on the start-up side but we can recoup those costs quickly by not having to reapply the savings to other equipment."

"The pricing for this solution is reasonable."

"The solution is expensive; it is not the cheapest solution out there. If you look at it from a total cost of ownership perspective, then it is a very compelling solution. However, if you're looking at just dollar per terabyte and not looking at the big picture, then you could be distracted by the price. It is not an amazing price, but it's pretty good. It is also very good when you consider the total cost of ownership and ease of management."

"I always want things to be less expensive. However, I would say the pricing is fair. Their costs are in alignment with their competitors. It is a good value for the money."

"It's a high-cost offering amounting to three or four million Swedish kronor, or about $400,000 or euros, for approximately 480 terabytes of storage."

"Our company finds the pricing high, but it decreases over time."

"It is a really expensive solution."

More Dell PowerScale (Isilon) pricing and cost advice

"If one is a cheap solution and ten means it is a very expensive product, I would rate the price as two or three."

"It is expensive but might be optimal based on the partnership."
