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.

Shared storage capabilities provide enterprise value with good reliability

Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.

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

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

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

"It helps simplify our storage, because the user interface is very simple and the installation is easy."

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

"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."

"The initial setup is pretty quick."

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

More Pure Storage FlashBlade pros

"I rate the stability of Amazon FSx ten out of ten."

"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."

"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."

"The shared storage capability is highly valuable."

"On a scale of one to ten, I would rate Amazon FSx a ten."

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

"The stability of the solution is good."

"The most valuable feature for me is SyncIQ."

"The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed, which benefit my company by providing less downtime and less overhead."

"The fact that we were able to set it up, use it, and, for the most part, didn't have to worry about it after we had it set up has been valuable."

"Based on the flexibility of the system itself, it was easy for us to manage the growth by buying individual nodes as needed."

"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product. This solution has also had a positive impact on our employees' productivity because it reduces the amount of admin that our staff needs to handle."

"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."

More Dell PowerScale (Isilon) pros

Cons

"I would like to see more deduplication."

"It would be beneficial if the layer could support the S3 protocol and be container ready in the next release."

"The features provided for SMB customers are limited."

"There could be improvements in public cloud integration."

"I have not seen ROI."

"They need better integration with public clouds along with a better hybrid solution."

"A direct FTP feature would be beneficial instead of relying on transmission services."

"Dell PowerScale needs to reduce its price."

"The solution isn't suitable for small environments or small customers."

"The analytics could be improved."

"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."

"The product needs to improve CLI since commands are complex. The search option is also difficult since you must give the full path."

More Dell PowerScale (Isilon) cons

Pricing and Cost Advice

"Licensing fees are paid yearly."

"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."

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

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

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

"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."

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

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

More Pure Storage FlashBlade pricing and cost advice

"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."

"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 platform is not cheap. However, on the software side, you can choose what you want license. So, you can start your licensing with the features that you need, then after buying the platform add some other features."

"This solution is priced slightly higher than others on the market but does offer good quality. With this solution's data reduction and compression, we were able to purchase less. Costs have dropped because of the data rate of compression and deduplication."

"Dell PowerScale is an expensive solution compared to other products like Qumulo."

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

"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."

"The price of the solution is high."

"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."
