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.

Has improved data reliability while requiring better pricing and localized support
The most valuable features of Arcserve OneXafe are improving persistent data, which I believe is very important. I use other products too, not only Arcserve OneXafe; we use TrueNAS as well. I have utilized Arcserve OneXafe's data deduplication feature. It helps my storage efficiency significantly. The product satisfaction with this product helps with storage efficiency. Regarding Arcserve OneXafe's immutable object storage helping against ransomware, the call was not clear, and I had difficulty listening to what was discussed. Arcserve OneXafe improves precision of data. I have used Arcserve OneXafe's continuous data protection. This is beneficial for operational continuity because we use it constantly. I have no objections to Arcserve OneXafe technology; I think that is very good.

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 performs well and it is also very fast."
"We have seen a reduction in the total cost of ownership by around 20%."
"The most valuable feature of this solution is performance."
"Using this solution has made our backups more reliable."
"The solution is able to handle workloads and is easy to use. It allows us to actually manage the boxes in less time."
"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."
"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."
"The most valuable feature is Safe Mode."
"The most valuable features of Arcserve OneXafe are improving persistent data, which I believe is very important, and I have utilized Arcserve OneXafe's data deduplication feature, which helps my storage efficiency significantly."
"The simplicity and the ability to perform small backups are the most effective features for data protection in Arcserve OneXafe."
"The simplicity and the ability to perform small backups are the most effective features for data protection in Arcserve OneXafe."
"The most valuable feature of Dell PowerScale (Isilon) is all the capabilities together."
"The stability of the solution is good."
"The solution allows me to use SSMDS to store data for end users and share it within different locations."
"The solution's scalability is very good."
"Our users are able to easily roll back snapshots without going through IT."
"The solution is stable."
"The single pane of glass for both IT and for the end-user is a valuable feature. On the IT side, I can actually control where things are stored, whether something is stored on solid-state drives or spinning drives... The single pane of glass makes it very easy to use and very easy to understand. We started at 100 terabytes and we moved to 250 and it still feels like the exact same system and we're able to move data as needed."
"This is the best platform that we could have for storage utilization. It is affordable and scalable. At the end of the day, it's something that we find very easy to use."
 

Cons

"I have not seen ROI."
"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."
"The feature that we're waiting on is better integration with the cell services."
"Its configuration should be easier."
"I would like to see more VM-Aware features in the next release of this solution."
"I would like to see more deduplication."
"It would be nice if you could store file-based in the same box with the same technology."
"The documentational aspect of FlashBlade needs improvement."
"The price is not the best; it is too high."
"Arcserve OneXafe is not used in many cases in the market that we work in."
"The price is not the best; it is too high. It's not the best solution in terms of price, although the solution itself is good."
"The replication could lend itself to some improvement around encryption in transit and managing the racing of large volumes of data. The process of file over and file back can be tedious. Hopefully, you never end up going into a DR. If you do go into a DR, you know the data is there on the remote site. However, in terms of the process of setting up the replicates and filing them back, that is just very tedious and could definitely do with some improvement."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear. We've got four different products that look after the Isilon, management-wise, and it's a bit of a mess."
"The biggest weakness is small file handling. Small file compression options are not enabled out of the box. It would be good to have this enabled by default."
"There are some missing features in the product, especially when our company needs to do some tape backup, and we see that the tool doesn't have integration capabilities."
"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."
"There aren't many templates still coming out for it. They need to provide templates so we can copy and paste what we've done in the past to future, new things."
"Isilon has limitations on the number of files that can be generated."
"The solution can be integrated with an automation system. Dell uses another framework developed in-house. They can integrate it with machines."
 

Pricing and Cost Advice

"The price of this solution could be made more affordable."
"The product is very expensive."
"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 licensing is renewed annually."
"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."
"I understand that it is competitively priced compared to other brands."
"The pricing for FlashBlade is between cheap and moderate."
"In my opinion, we have paid the right price for the product. I don't think that it is too much or too little."
Information not available
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"Pricing for this solution is reasonable."
"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."
"The price of the solution is high."
"The solution's licensing cost varies based on capacity and performance requirements."
"Dell PowerScale is an expensive solution compared to other products like Qumulo."
"The general cost for a system like this is expensive. The total cost depends on your use case. You need to pay for every additional feature that you use."
"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."
