Technical Lead at Wipro Limited
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.

Solutions Architect at a healthcare company with 10,001+ employees
UI has simplified pixel data insights and cost savings while hardware lifecycle still needs work
There is an option I would like to see. Instead of installing a separate Grafana server to get the telemetry data, why can we not set up the same capability in the UI itself? Then we could choose the retention period of the log and get everything inside the Qumulo dashboard itself, rather than installing a separate Grafana server, because we need to maintain a separate server to collect these metrics. There is one more needed improvement I noticed. If you compare Qumulo to Dell Isilon as a vendor, a patch update with Dell Isilon covers the hardware as well. In Qumulo, however, you have to maintain the hardware lifecycle and the software separately. This means every time you update your server, you have to update two entities: one is the hardware and the other is Qumulo. So it might be quite challenging. A great deal of time is also involved for an engineer to do both of these things, so I do not think Qumulo can directly integrate with the hardware so that we can update the Qumulo software together with the hardware patches. Right now, I do not have any other improvements needed for Qumulo that I have not mentioned yet.

Quotes from Members

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

Pros

"Pure Storage FlashArray simplifies maintenance and management with its intuitive GUI, making storage allocation and other processes easy to understand, even for beginners."
"If I want a product which has reliability and high speed, and Pure Storage is the first name that comes out of my mouth."
"Pure Storage FlashArray has significantly improved our data center performance. It handles high workloads efficiently, providing better performance in the environment. With increased storage capacity, it has led to improved overall system performance. The tool's technology is a standout feature. It has helped me reduce storage costs by 15 percent."
"It simplifies building out the storage."
"The white glove customer service that I get is their greatest value."
"It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."
"The features that are there now are really what we need."
"Access speed and power consumption are most valuable."
"The dedupe and compression are pretty extreme. On disk, we're getting dedupe rates of up to 65 percent of data and compression of 34 percent. When you go to the cloud, it's more like 76 percent for dedupe and almost 50 percent for compression."
"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."
"Not having to be onsite to swap tapes on a daily, weekly, or monthly basis, alone, has really paid for its usage through the savings in time."
"Quest QoreStor definitely saved us money."
"Since we started to resell QoreStor, we have been using it internally; it's better than other backup solutions we have used or evaluated."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"We need revisions and safe backup so that it could be held up in court, but deduplication and compression are the main features why we have Quest QoreStor. That's where it really shines. I use ZFS and XFS at home, and Quest QoreStor is even better."
"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 feature is real-time analytics."
"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."
"All in all, it's a very good product, resilient, with good performance and scalability that is pretty easy."
"The most valuable features of Qumulo are its rolling updates and all-day availability."
"Overall, I would rate Qumulo a nine. I appreciate that it does snapshots, and you could use replication."
"Qumulo has positively impacted my organization with the scalability of size; we were at one petabyte and we were able to increase it to two petabytes, and increasing our storage from one to two petabytes was a smooth process and it was easy to increase size."
"The most valuable feature of Qumulo is the ability to share files and reliability."
 

Cons

"Larger capacity and more storage ports would be the two things I'd like to see."
"The scalability of the solution is extremely costly."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"We have not had a good experience with the IBM device."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"The technical support is okay, but could be improved."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"The setup of the software is definitely not the easiest thing. I worked a lot with Quest engineers, especially in the early days when we were first testing it and trying it out. I actually had some of the developers working with us at one point because they were going through these point releases, and I was having trouble getting it to work in this S3-compatible situation. We got it all working eventually, but setup is definitely not the easiest thing in the world."
"The setup of the software is definitely not the easiest thing in the world."
"The management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"The ransomware protection of QoreStor could use improvement."
"They could improve on support a little bit. We have not had to engage their support much, but when we do have issues, it can take longer to get things resolved."
"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 main hiccup, as I mentioned, is that the hardware lifecycle patch is the most critical issue."
"I have not seen a concrete return on investment with Qumulo, as the project scope does not allow me to assess metrics such as money or time saved."
"Qumulo should continue to expand automation and orchestration capabilities."
"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."
"The support for iMac and protocols should be improved, not all features are available."
"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."
"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

"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"There is always room for negotiation."
"Pure Storage is expensive. It comes with features, so you get what you pay for. It is expensive compared to our old storage systems, but from the amount of human effort that you have to pay to babysit a storage system, it reduces that. I don't know if the TCO is reduced, but it's not a concern for us."
"It could always be lower, but it's okay."
"I would prefer that they lower their pricing."
"There are no licensing fees aside from the support."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"The price of the Pure Storage Flash Array is too high and there needs to be more contact clarity. We went with the Evergreen plan and I don't have clarity on what am I supposed to pay each year or every three years. There was not much contract clarity."
"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."
"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."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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."
