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.

Enables effective data management with reliable backup and recovery

Cohesity SmartFiles aids in data management with features like full-text search through indexed documents. The architecture supports backup, ransomware awareness, and data management on a converged platform, offering triple-protocol access (NFS, CIFS, and S3) while facilitating gradual improvements in access rights management. It allows for redundant setups, with automated backup and recovery options in a cloud environment.

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

"The tool's most valuable features are data warehousing, speedy recovery, and analytics. Its latest release is cost-effective."

"The most valuable features of FlashBlade include its replication capabilities, reports, and easy allocation. Everything is user-friendly."

"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."

"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."

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

"The onboarding and integrated monitoring tools are pretty good."

"The product is scalable and easy to expand."

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

More Pure Storage FlashBlade pros

"Cohesity SmartFiles aids in data management with features like full-text search through indexed documents."

"PowerScale has made it extremely easy to scale file data across our organization. We have two implementations of Isilon. One is a replica of the other. When scaling, we add nodes to each location and expand the cluster. The process is straightforward."

"The guaranteed performance, combined with the scalability through its scale-out capability, makes it an excellent choice."

"The best thing is that it works. We don't have to maintain it too much; we usually upgrade once a year."

"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."

"What I like the most about Dell PowerScale (Isilon) is that the storage capacity is very high."

"The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity."

"The capacity and scalability are what I appreciate the most about it; that was huge for us. We saw its benefits immediately after we started using it."

"I buy Dell PowerScale (Isilon) because of the price, service, and technology, and the technology that is particularly good for my company is that I have two Dell PowerScale (Isilon) systems in two sites, and I use replication between them with Superna software, which is a third-party Dell technology."

More Dell PowerScale (Isilon) pros

Cons

"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."

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

"Its configuration should be easier."

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

"The solution is expensive."

"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."

"It would be nice if you could store file-based in the same box with the same technology."

"It's on the expensive side, as expected for a niche product."

More Pure Storage FlashBlade cons

"Users must remember that running DataProtect and files on the same cluster could threaten access if there is a platform failure. It's not suitable for applications needing high I/O or low latency."

"The product’s expansion capacity, pricing clarity, and ease of use need improvement."

"I would like to see Dell PowerScale (Isilon) improved by enhancing the user interface, OneFS, to make advanced conversation and troubleshooting more specific, upgrade and batch management, providing deeper built-in analytics for performance and capacity planning."

"I have escalated questions to the technical support team of Dell, and I find the support center to be very poor compared to what it was during EMC's time."

"The thing that they are working on now, and we are following closely is more native cloud integrations. The way that we envision workloads in the future is around moving compute to data instead of the other way around. So, we would like to have a single pane glass to manage storage across a variety of different platforms, including native cloud. That would be awesome."

"I would make Dell PowerScale (Isilon) better by improving SmartSync in the graphical user interface. Currently, everything has to be done through the command line, and I prefer having a graphical interface."

"The pricing could be reduced."

"Improvements could be made on the object storage side."

"I would want to see more AI features with Dell PowerScale (Isilon)."

Pricing and Cost Advice

"Our customers have seen a reduction in TCO."

"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."

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

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

"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."

"Licensing fees are paid yearly."

"Our licensing is renewed annually."

Information not available

"The only drawback for us is that it's a large upfront investment. This was a huge decision for a startup company to make. It took a bit for us to get over the line on it, but we have not regretted it."

"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."

"We paid an additional fee to have Dell's ProDeploy Plus team implement it."

"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."

"It is a really expensive solution."

"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."

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