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.

Backup storage has shrunk dramatically with deduplication but still needs stronger security options
The air gap feature is something I'd really like to see in QoreStor. There's no native air gap capability right now, and for security-conscious environments, that's a gap. The configuration export is also limited in QoreStor. If you want to document your setup or migrate configuration to a new instance, it requires more manual work than it should.

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 first set up we had was really straight forward and simple."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"All updates, upgrades, and hardware work are all performed on-line with no impact."
"It simplifies storage."
"Before we used Pure Storage it took 93 days of employees who run the database to back up and restore databases, and the scale of deployment basically went from several days to a few minutes."
"The money I saved by not renewing maintenance on the Dell EMC devices paid for the Pure Storage devices."
"This solution has improved the way our organization functions through its reliability and consistent platform for storage and has helped us to simplify storage because the management tools make everything a lot easier."
"The compression and deduplication features help to make the best use of the capacity."
"This software solution can be installed on many different types of hardware, which makes it very flexible. We can run it on virtual machines or virtual servers, providing convenience for solutions of varying sizes, from small to large."
"The extreme compression of data is a big thing for us. We were looking for an online backup solution, and QoreStor is very good in terms of data compression. It helps us minimize the required storage in the Blob Storage environment."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"QoreStor has helped us to reduce our backup storage requirements on-premises. We've been using the same devices for quite a while, and so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution. The advantage here is even if we had to retire the hardware tomorrow, the QoreStor part doesn't change. We just have to have additional hardware and put the solution back on whatever hardware we pick and it'll do the same thing."
"Quest QoreStor definitely saved us money."
"Deduplication is the most valuable feature. It saves us a lot of space. When we back up 100 terabytes of data, after dedupe, it only uses maybe five to six terabytes for the disk space in QoreStor."
"Quest QoreStor is very stable compared to our previous solution."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Qumulo has positively impacted my organization by simplifying storage management while providing a single, scalable platform, reducing administrative efforts, making storage growth easier to manage, and allowing users to experience consistent performance."
"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 the ease of management and special permissions that are quick to enable. The overall performance of the solution is good."
"The most valuable feature of Qumulo is the ability to share files and reliability."
"The most valuable feature is real-time analytics."
"It is a very stable product. I never faced any issues."
"One of the best things I love about Qumulo is the performance and the support available."
"The feature that I like most is the analytics part of the file system."
 

Cons

"Everpure FlashArray can be improved as the pricing is expensive, but you do get what you pay for; you are paying a premium for better service, better warranties, less downtime, and other things, so I do not know that a lower price would work out because you probably would not have that high of quality for those things."
"The scalability of the solution is extremely costly."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."
"Reports of performance and LUN utilization could be improved."
"I would rate this a seven out of ten because it's a good performance storage, but the price is a little bit high."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"The air gap feature is something I'd really like to see in QoreStor."
"There can be some kind of monitoring solutions to alert users to issues with the appliance or software, making it easy for customers to monitor their systems in the field."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something. So that when we don't do a backup, we want the QoreStor to stay offline. It would be a nice feature to have."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"Support is one point of improvement for Quest QoreStor. Support is sometimes not adequate."
"The importance of support is significant to me. I was working for a service provider, and all of our customers had a Quest or warning. Sometimes the support really underperforms."
"The ransomware protection of QoreStor could use improvement."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial. After everything is set up and configured, there should be a way to export the configuration. In case something happens to the QoreStor server, and we need to reinstall and configure everything, being able to import the configuration would be helpful. This feature does not currently exist."
"The price of the software is a bit expensive, so a reduction in cost would make it more competitive."
"Some services are not at par with competitors today, and services such as pricing, licensing, and reporting can be better."
"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."
"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."
"There is plenty of room for improvement. In the future, I would like to see non-disruptive updates."
"In the next release, I would like to see the ability to have more control at a terminal level of the file system."
"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."
 

Pricing and Cost Advice

"Price is about the only thing that's wrong with it. A little bit better pricing would be great."
"There are no licensing fees or other costs."
"I would prefer that they lower their pricing."
"The solution is expensive."
"The best features come included without any additional cost."
"It's a good price point and it's a solid product for the price."
"It could always be lower, but it's okay."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"Quest QoreStor's pricing is affordable. We evaluated Veeam, a well-known company for backup solutions, but found their pricing to be quite high. Veeam's price was almost double. For us, Quest QoreStor is very affordable."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The pricing is good. It is competitive for a managed services provider. I like the ability to pay by the terabyte, allowing for an incremental cost that we and our customers can afford, so the solution grows with the customer."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
