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.

Useful data sharing, simple cluster scaling, and excellent support
One aspect of Qumulo that I hoped to see improved was its software upgrade process, which did see significant progress during my usage. Initially, upgrading the software resulted in several minutes of system downtime. However, by the time I departed last summer, the downtime had reduced to mere ten seconds. Although I am unsure if Qumulo has yet achieved a completely outage-free upgrade, I simply performed the upgrades early in the morning before the marketing department began its workday, so any downtime was inconsequential.

Quotes from Members

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

Pros

"The fact that the solution is extremely stable and it works really great each dollar spent on this solution is worth it."
"I love this solution."
"Among its most appealing features are its ease of handling and minimal maintenance requirements."
"The initial setup was straightforward. If you know how to plug in power and network you're pretty much qualified. They were on site to configure the network, the box to fit into our network architecture. Other than that, we self-managed from there."
"The number one aspect of FlashBlade is performance; the ability to move large amounts of data through a training array is pretty much unparalleled, and the scalability has been great."
"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."
"Approximately 40% to 50% of my time is saved using Pure Storage FlashBlade compared to different products."
"The most valuable features of the solution are flexibility and ease of implementation."
"Of all the components in our IT system, it's probably the least troublesome."
"Dell PowerScale (Isilon) actually combined a shared file system that scales seamlessly and works effectively, making the blocking and tackling exactly what was advertised."
"Dell PowerScale (Isilon) is scalable, it is easy to expand capacity, and the solution is suitable for companies with a lot of data."
"The most valuable feature of Dell PowerScale (Isilon) integration with other solutions because of the standard file system protocol."
"The recent introduction of inline deduplication and compression has drastically improved our efficiency ratios to make it an economical product."
"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 solution allows me to use SSMDS to store data for end users and share it within different locations."
"The most valuable feature is real-time analytics."
"The ratio of total operational cost to complexity versus feature set is very good."
"The most valuable feature is real-time analytics."
"The data protection algorithm to protect the data between the nodes has been the most valuable feature. The integration with backup platforms such as Veeam and Veritas has also been valuable."
"The most valuable features of Qumulo are its rolling updates and all-day availability."
"The most valuable features of Qumulo are the ease of management and special permissions that are quick to enable. The overall performance of the solution is good."
"The ratio of total operational cost to complexity versus feature set is very good."
"The most valuable feature of Qumulo is the ability to share files and reliability."
 

Cons

"I would like to see more deduplication."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person. Nine out of ten times, we get an email right back saying that person is off until tomorrow. I cannot handle that. They just did this over the weekend to us, too. I had to call our rep and have them do something about it."
"There could be improvements in public cloud integration."
"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 speed could be improved."
"They need better integration with public clouds along with a better hybrid solution."
"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 speed could be improved."
"Because of the magic that it does 'under the hood,' it is very difficult to find out within the system where all your storage is going."
"The management and monitoring tools comprise a disparate suite of products and the roadmap is very unclear."
"The pricing is expensive, but I think it's a fair value because it does manage itself."
"Dell PowerScale (Isilon) could be improved, particularly the UI, which could use some polishing as far as ease of use for the customer."
"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."
"Technical support could be improved. Whenever we have a hiccup, we'd like to get it fixed maybe quicker."
"Dell PowerScale (Isilon) certainly has room for improvement; since it does not provide SAN at the moment, I would look for Dell to create a complete unified solution just like NetApp."
"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."
"The solution could improve availability and improve data protection or data services such as compression of deduplication. In a future release, we'd like to have more cloud API integrations."
"Qumulo should continue to expand automation and orchestration capabilities."
"In the next release, I would like to see the ability to have more control at a terminal level of the file system."
"The price of the software is a bit expensive, so a reduction in cost would make it more competitive."
"Some anti-theft permissions do not transfer well to Qumulo."
"Qumulo should continue to expand automation and orchestration capabilities."
"One aspect of Qumulo that I hoped to see improved was its software upgrade process, which did see significant progress during my usage. Initially, upgrading the software resulted in several minutes of system downtime. However, by the time I departed last summer, the downtime had reduced to mere ten seconds. Although I am unsure if Qumulo has yet achieved a completely outage-free upgrade, I simply performed the upgrades early in the morning before the marketing department began its workday, so any downtime was inconsequential."
"In the future, I would like to see non-disruptive updates."
 

Pricing and Cost Advice

"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."
"I rate the tool's pricing a seven to eight out of ten."
"Our customers have seen a reduction in TCO."
"The pricing for FlashBlade is between cheap and moderate."
"Licensing fees are paid yearly."
"The pricing is relatively expensive due to the FlashBlade technology. However, for companies needing quick and reliable data access, the cost is justified."
"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."
"The price of the solution can fluctuate. The price can be competitive or other times not. The price of the solution could be better."
"We paid an additional fee to have Dell's ProDeploy Plus team implement 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."
"The price of Dell PowerScale (Isilon) is reasonable."
"The pricing is excellent."
"It is an expensive product with a high storage capacity suitable for large data requirements."
"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."
"Dealing with the product costs and licensing areas is getting easier since Dell is simplifying the licensing process and licensing packages offered to users."
"The price of the solution is in the middle range compared to others. We look at the price per terabyte."
"The price of Qumulo is reasonable."
