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.

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.

Cost savings and efficient data management improve operations but support quality varies
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. I always had to get it escalated or ask for someone specifically because those other people would just read knowledge-based articles that I had already done myself. Quest QoreStor does not work with any backup software, server, or storage hardware. It has the hardware compatibility list, and you need a specific number of IOPS, so it needs to run on decent hardware at least to have enough input-output operations. Otherwise, the setup result will be canceled. I'm not too sure if there are still physical appliances, but when I first started, we had some customers with a physical Quest QoreStor appliance, and it would only run on certain hardware. It doesn't work with every backup program. For example, Veritas Backup Exec is incompatible, but Veeam is compatible, and V Ranger is compatible as well. I didn't even know that Quest QoreStor has any static AI and behavioral AI technologies.

Quotes from Members

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

Pros

"Our clients see a reduction in total cost of ownership by around 40%."
"The most valuable features of Pure Storage FlashArray are simplicity, ease of use, and dashboard management."
"The scalability is good."
"In comparison to the competitors, Pure is very price-competitive for the future functionality that it provides."
"The most valuable feature is the speed of it, as it is much faster than anything that we can get from similar competitors, and the solution helps to simplify storage."
"I like its speed. It has all the features that I need."
"All our junior partners can administer the storage arrays. It is simple and easy to use. We don't have to dedicate a whole team of full time people to work on it."
"The stability is very good. I've done destructive testing on it and never had any type of storage outages from it."
"As a Pure Storage platform, the cost-benefit is hugely based on the deduplication and capacity."
"I like its size. It is smaller than the other competitors. We can plug in many blades, and we can have data up to one terabyte."
"It is very easy to use, and it is very fast."
"Pure Storage FlashBlade is user-friendly. It's replication feature is great because it has active replication and active DR. That's the beauty of the product. It's a perfect solution for block storage."
"It is very easy to use, and it is very fast."
"The fact that the solution is extremely stable and it works really great each dollar spent on this solution is worth it."
"The solution provides many controllers; more controllers lead to higher performance, and it is a unique feature provided by the product that other tools do not have."
"FlashBlade offers low latency, high throughput, and seamless scalability."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"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."
"QoreStor has helped to reduce our backup storage requirements on-premise by at least 90%."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
"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."
 

Cons

"We haven't seen ROI yet."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"This product has only two active controllers, whereas other solutions can have more. This is something that needs to improve."
"I have been primarily working with storage and have not fully explored other areas, but there is some room for improvement when it comes to performance reporting."
"It's expensive, but you get what you pay for."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"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."
"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."
"In the realm of micro-services, I think that Pure Storage can do well if they start getting in there and making their arrays more micro-services ready."
"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 features provided for SMB customers are limited."
"The documentational aspect of FlashBlade needs improvement."
"The solution is expensive."
"Compared to, for example, Hitachi NAS, the solution is not mature at all. It's just in its infancy as far as technology goes."
"I would like to see the licensing fees improved as well as the price per terabytes."
"The technical support needs to improve. When we open a case, it is auto assigned to a support tech person, and nine out of ten times, we get an email right back saying that person is off until tomorrow."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"In terms of improvement, we would like to have an Air Gap feature to prevent a virus from attaching to something."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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."
 

Pricing and Cost Advice

"I have had a couple of customers who have complained about the cost. It can be a little more expensive than some of the other platforms. After it has been installed, I have never had a customer say, "I wish we wouldn't have spent all that extra money." They have always been happy with the product after it has been installed. They might be on the fence about it because of the price, but everybody who I have ever seen install it, they are always happy with it."
"They have a standardized fee; it's been the same price for 10 years straight. I am happy with the price — I think it's good."
"Its price is almost double than any other flash storage solution."
"We have an Evergreen Storage subscription, which I think is a great feature."
"We evaluated Oracle and Hitachi, but Pure Storage had the better pricing."
"The Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"There are no licensing fees or other costs."
"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."
"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."
"It's a costly solution, but Pure Storage FlashBlade doesn't require additional licenses. All of the software is combined into one bundle."
"Pure Storage FlashBlade is a hardware appliance, and it's very expensive if you compare its price with other solutions. You can get the same features and benefits from its competitor, VAST Data, but for half the price of Pure Storage FlashBlade."
"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 this solution could be made more affordable."
"The price could be cheaper."
"I rate the tool's pricing a seven to eight out of ten."
"Our customers have seen a reduction in TCO."
"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."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"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."
