Has improved performance for mission-critical workloads and enabled seamless non-disruptive upgrades
The availability is 99.99%, which is the main factor any customer would need because their data should be available whenever they want to access it. This is one main critical thing. It is very easy to upgrade since Pure Storage FlashArray handles it well. Everything is non-disruptive now; previously, there were forklift shifts, but now that is not the case. Pure Storage FlashArray says no to forklift upgrades. Usually hardware requires downtime, but Pure Storage FlashArray has improved their footprint so that they are not asking for downtime; everything is just a non-disruptive activity, which is why customers are more inclined towards Pure Storage FlashArray. Customers want more of the models in their environment due to the performance they are giving, and everything is in one Pure1 Array console where we can view all the models on one page or just an orchestration tool. You don't miss anything; you have replication, notifications about replication, and details about which host groups replication is happening in and if that replication is successful or failed. On a daily basis, our purpose is to create volumes for infrastructure; our daily activities include creating volumes and mapping them to the host, doing any migrations from a VM, clearing the data stores, and carving the volumes to those VMs. One key factor is the data compression with a ratio of 5:1, focusing on space efficiency, inline deduplication, and the compression Pure Storage FlashArray works on; that is a major factor we can suggest to any customer. Analytical capabilities are crucial. Daily, we check the throughput and consumption, and Pure Storage FlashArray provides predictions for one year regarding usage. This prediction helps plan updates well ahead. For support, we just raise a case, and they follow up and get it done. There is also AI readiness, but with the model R2, we don't have much of that AI readiness. For others, we do have AI readiness that predicts capacity based on daily or monthly trends, enabling us to analyze how much space we need or if we need to expand the disk shelf. From an operational point of view, a good feature is that if you accidentally delete a volume, it will be retained in the destroyed state for the next twenty-four hours, which is not the same with any other vendor. I have worked in this storage domain for the past fifteen years, and this option is remarkable, benefiting any L1 or L2 engineer. Additionally, from a compliance perspective, Pure Storage FlashArray has REST APIs enabled. I have not explored automation much, but from a security standpoint, it is strong with encryption data. If you want to automate, you can easily integrate with all clouds and explore Pure Cloud for scheduling workloads, including volume creation. Customers find benefit in Pure Storage FlashArray's single management pane of glass due to the dual controller and active-active setup. If one of the controllers goes down, all workloads automatically shift to the other controller, ensuring their data is safe and accessible at all times. This is a highlighted feature that any customer desires because their data should always be accessible. For SAN workloads, we use Pure Storage FlashArray because for SAN FC fiber channel, we don't use it; we use NetApp for NAS activities. We have clearly split this, so SAN is for mission-critical applications, while network-attached storage handles file systems. This architecture helps us maximize the benefit from Pure Storage FlashArray due to the significant workloads from this giant retail client. From a footprint and energy consumption perspective, you can see energy consumption from the Pure1 storage portal on a daily basis, and it is very compact. The three models we use consume only three units, which is quite low. From a footprint and data center perspective, it doesn't occupy much space. As everything moves to cloud, there are requirements to avoid excess spending on data centers, and Pure Storage FlashArray is efficient in energy consumption and is environmentally friendly.

Operates seamlessly and minimizes downtime while meeting enterprise file share demands
The features of Dell PowerScale (Isilon) that I appreciate the most include the scale of architecture and the way it is designed. These features benefit my company by providing less downtime and less overhead. While I have not calculated an exact number regarding the reduction in downtime, we have always been using the product, so we have no baseline to compare it to. However, it is a very good product. Dell PowerScale (Isilon) scales very well with the growing needs of my company.

Unified file platform has delivered secure multi‑protocol access for massive data growth
The creators of Qumulo were the ones who created Isilon, and I had a conversation with them, so any of the features within Isilon may need tweaking, but I think they resolved it here. In the year that I worked with it, I did not see anything that I had an issue with. The security is great, and it works with cloud technologies, being a hands-based tool, so you can use it with AWS or Microsoft Azure. It programs very easily. There are REST APIs, and there is a cloud connection. The management and program layer is made up of three capabilities: API, the command line, and a visual interface. In the year that I worked with it and brought it in, I think it has been effective. The only thing I would like to see added to Qumulo is for the interface to improve visually, more in line with vCenter, but that is just my thought. Overall, I appreciate it.

Quotes from Members

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

Pros

"The experience has been very good so far for the company."
"It is fast and reliable. It works."
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"Now they are trying to add more and more applications because they're getting better performance and stability."
"The seamless integration into the public cloud has improved my organization."
"It has made working with storage as easy and simple as it should be."
"It makes things ten times easier."
"The best features of Pure Storage are their support and analytics."
"Dell PowerScale overall is easy to use."
"The most valuable feature of the solution is the unlimited scalability. The tool has high availability and high storage capacity."
"The most valuable feature is its single space of storage."
"Of all the components in our IT system, it's probably the least troublesome."
"My favorite thing about Dell PowerScale is its scalability."
"I don't have to rebuild the cluster to add a node."
"Isilon is flexible in supporting various data workloads while keeping them protected. Dell continues to release updates and patches which enhance the use of this solution. This includes offering ransomware protection."
"It's helpful that we're able to scale the number of nodes without having to build additional clusters."
"Overall, I would rate Qumulo a nine. I appreciate that it does snapshots, and you could use replication."
"The ratio of total operational cost to complexity versus feature set is very good."
"It is a very stable product. I never faced any issues."
"The most valuable feature of Qumulo is the ability to share files and reliability."
"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 feature that I like most is the analytics part of the file system."
"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."
 

Cons

"There are many features which need to be added, particularly on the replication side."
"The solution needs an integrated NAS platform, file platform."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"Once, before Pure went public, we were a member of their customer advisory board and beta tested replication. One requested enhancement yet to manifest is the scheduling of snapshot replications."
"The data reduction that we had initially anticipated when we bought Pure and we move over, is way lower than the expected reduction. It depends on the workloads, of course. But that has been a challenge at times."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"A noticeable area for improvement is the support for object storage. The FlashArray does not natively support object storage like S3 or Swift, which pushes customers needing these features towards the more expensive FlashBlade."
"Dell PowerScale's deployment is not easy."
"I'd like to see more Iceland products in the cloud so that we can port our data into different environments if needed. I would also like to see a virtual appliance or software-defined Iceland product."
"Dell PowerScale (Isilon) could be improved, particularly the UI, which could use some polishing as far as ease of use for the customer."
"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."
"Dell PowerScale (Isilon) could improve in terms of having some problems with using IPv6 and IPv4 on the same namespace at the same time, which is one of our biggest problems as you have to do some really bad workarounds to get that working."
"In the past year, it hasn't been as great. They seem to just follow KBS."
"Some improvements to the NFS support would be of interest to us."
"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 price of the software is a bit expensive, so a reduction in cost would make it more competitive."
"The support for iMac and protocols should be improved, not all features are available."
"Qumulo should continue to expand automation and orchestration capabilities."
"The only thing I would like to see added to Qumulo is for the interface to improve visually, more in line with vCenter, but that is just my thought."
"Some anti-theft permissions do not transfer well to Qumulo."
"There is plenty of room for improvement. In the future, I would like to see non-disruptive updates."
"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 next release, I would like to see the ability to have more control at a terminal level of the file system."
 

Pricing and Cost Advice

"The cost of Pure Storage is subjective and determined by your environment. Pure Storage tends to be more expensive than NetApp, but it is cheaper than EMC. Performance varies with data workload, making cost considerations complex."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"The pricing of Pure Storage is all-inclusive. It is very fair, and very easy. In comparison, Dell EMC has licensing that needs to be added if you wan to work in a complex environment or in specific functionalities."
"It's a good price point and it's a solid product for the price."
"I don't know the exact cost but it's around $1,000."
"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."
"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."
"We paid an additional fee to have Dell's ProDeploy Plus team implement it."
"It is an expensive solution."
"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."
"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 Dell PowerScale (Isilon) is reasonable."
"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 Qumulo is reasonable."
"The price of the solution is in the middle range compared to others. We look at the price per terabyte."
