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.

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

"The most valuable features include the ease of implementation, ease of use and the speed that you can do backup and recovery on."

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

"Using this solution has made our backups more reliable."

More Pure Storage FlashBlade pros

"The shared storage capability is highly valuable."

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

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

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

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

"Its most valuable feature is the DR capabilities replication."

"Dell PowerScale overall is easy to use."

"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."

"We use the solution internally to support our own managed servers and run our own support center."

"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."

"It assists with eliminating storage silos because it provides SMB and NFS protocols. PowerScale has also helped free up our employee's time to focus on other business priorities."

"The inter-cluster replication feature, called SyncIQ, allows you to set up all of the jobs and move your data entirely, either timely or all at once."

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."

"We haven't been able to use much of the cloud area of Pure Storage. We have a storage server and it would be better if it could integrate with other cloud features of this solution."

"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."

"The solution is expensive."

"Commvault has mainly driven the Analytics, providing data and reports. However, the product has room for improvement, especially regarding storage analytics. Upgrading firmware has caused issues, requiring feature disabling to revert to traditional backups. The firmware upgrades sometimes affect Commvault backups."

"The documentational aspect of FlashBlade needs improvement."

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

More Pure Storage FlashBlade cons

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."

"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."

"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."

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

"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."

"Since our Dell PowerScale (Isilon) is our own on-prem in-house built system, we don't have many up-to-date resources, and we're still a few years behind."

"Pricing is an issue. It's quite expensive for the amount of storage we have."

"Dell PowerScale (Isilon) is a little bit pricey, and its pricing could be improved."

"We have issues in Brazil with the procurement of solutions because we have to check the entire market and justify the pricing to our audit institutions, making it difficult to keep with the same vendor."

"The only thing that I think PowerScale could do better is improving the HTTP data access protocol. At the present, you cannot protect access to data via HTTP or HTTPS the same way that you can secure data access through other protocols like NFS or SMB[...]the Unified Permission Model that would allow a user to authenticate before being able to access a private file, does not apply."

"The price of the solution could be reduced."

"The UID mapping and how to configure mapping-related things is a struggle."

"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."

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

"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."

"We used a reseller for the purchase."

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

"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."

"Our customers have seen a reduction in TCO."

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."

"Pricing for this solution is reasonable."

"The solution's licensing cost varies based on capacity and performance requirements."

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

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

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

"It is a really expensive solution."

"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."

"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."
