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.

Storage Server Operations Senior Engineer at a media company with 11-50 employees
Seamless upgrades have boosted reliable block performance and simplified data center operations
Using block storage with Everpure Evergreen One has helped my production workloads primarily through performance and reliability. The performance is excellent because of Pure's simple architecture with just two controllers. Everpure Evergreen One offers exceptional features, including hardware that is compact and does not occupy multiple racks in data centers. The cooling and electricity savings are significant, and the ease of management means that even someone without any experience can manage Pure. The ease of management has helped my team because storage provisioning is straightforward. You can provision storage with just two clicks without waiting. There is no spinning, no loading, nothing—just one action, assuming you have already completed the zoning and added the hosts and host groups. Everpure Evergreen One has positively impacted my organization because the Evergreen model provides a hardware refresh every three years, essentially giving you new hardware and better performance, which is one of the coolest things. From these hardware refreshes, I have seen specific outcomes including no downtime at all. I performed a controller upgrade from M series to X, and it was seamless—no downtime, just one controller replacement at a time, with no performance issues and data still accessible.

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.

Quotes from Members

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

Pros

"It upgrades in place which means we'll be using it well into the future."
"We like the data reduction rates. That has been really helpful. You get 4U of Pure storage replacing something like two racks of spinning disks. One of the things that has contributed to that are the data reduction rates."
"The initial setup was really straight forward."
"My favorite feature about Pure Storage FlashArray is definitely the simplicity; in one word, it's simple to install, simple to upgrade, simple to maintain, and simple to manage."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"The most valuable feature is replication."
"Compared to Unity, these arrays offer significant advantages, such as NVMe technology and higher IOPS."
"This was our first all-flash storage enclosure, so we saw huge boost in performance for all of our servers."
"Everpure Evergreen One has impacted my organization positively because, as an SI company, when we buy it in bulk and share it among multiple other customers, it helps us with the shared model and how we can handle the entire workload."
"My advice to others looking into using Everpure Evergreen One is to stop looking at other solutions; you have already found the best one."
"The Evergreen program is excellent, and the pricing is quite reasonable. My friends who work there are doing very well and consistently achieving strong results. Like any company, they experience occasional downturns but perform impressively overall."
"Everpure Evergreen One offers exceptional features, including hardware that is compact and does not occupy multiple racks in data centers, with significant cooling and electricity savings and such ease of management that even someone without any experience can manage Pure."
"Everpure Evergreen One has positively impacted my organization by improving sales, enhancing performance of the Pures, strengthening support, and providing our clients with more security in their storage."
"Everpure Evergreen One helps us to grow our business and sales; those are the two big points that we continue to offer the brand."
"We have snapshots. We put snapshots on disks, and we can save information. In the case of ransomware, everything is in the snapshot. We have a snapshot lock on it, so it's safe."
"Everpure Evergreen One has been my go-to storage platform for years, positively impacting my organization."
"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."
"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."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"Data deduplication and replication would be the top two features. The encryption and cloud tiering are also attractive for the future."
"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."
 

Cons

"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."
"I would like FlashArray to add reports that help us forecast our predicted resource needs based on current usage."
"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."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"We have not had a good experience with the IBM device."
"It is a bit expensive."
"Everything has been good, but we faced one issue last year while migrating volumes from one Pure Storage to another. The snapshots were not visible in the Veeam backup portal."
"I would love to see a true one click upgrade solution."
"Many customers report that the starting price is quite high. However, the overall total cost of ownership can be reduced over time due to features like the Evergreen architecture, which allows savings through less management and environmental benefits."
"I'm not sure if any improvements are needed."
"Everpure Evergreen One could be improved by being slightly more flexible with the pricing model."
"I would love to explore more options on what Pure Storage Evergreen One can offer in general, mostly from the cybersecurity perspective and air gap."
"It would be nice to have support in Swedish."
"Customers are very happy with Everpure Evergreen One solutions; however, it could be improved with better prices and availability of new storage or flash arrays."
"The only potential drawback is that Pure Storage might be overkill if you don't need microsecond response times."
"To me, I think it's a little expensive. Then again, you get what you pay for."
"The air gap feature is something I'd really like to see in QoreStor."
"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 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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
"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."
 

Pricing and Cost Advice

"Pure Storage FlashArray is expensive."
"Cost-wise, it's been very effective."
"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"You get what you pay for. It is expensive, but it really works."
"We have seen a reduction in total cost of ownership (TCO)."
"The price was more favorable than Dell EMC."
"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."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"The pricing is very good."
"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."
