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.

Solution provides stable and efficient object storage with extensive API support
We have huge data of image and video files and we needed a solution for our customers. We were looking for object storage and found Dell ECS to be a very good solution Dell ECS is a very stable solution and most of the S3 APIs are supported. It is power-efficient and fits into a small space due…

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

"Their evergreen solution is probably the most needed in any industry, especially today in unprecedented times and supply chain issues, their evergreen solution is amazing."
"This solution has improved my organization because it has good performance."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"I like FlashArray's ActiveCluster as well as its snapshot and cloning capabilities."
"The first set up we had was really straight forward and simple."
"Despite the overuse of buzzwords and re-classifications, the storage industry has actually seen dramatic improvements over the last 3-4 years."
"The experience has been very good so far for the company."
"The ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"The tool is easy to use."
"Dell ECS is very easy to handle, primarily because the web UI dashboard and everything is very easy to manage for every customer."
"I am pretty happy with this product."
"For the performance it gives, it's quite competitive."
"It is a stable solution."
"We have had a few issues but the support has been very good."
"The most valuable features are the S3 protocol implementation and the integration with other DELL EMC products, like ISILON."
"I am satisfied with this solution."
"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."
"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."
"If storage costs are a problem, whether on-premises or cloud, QoreStor is worth a serious look."
"Quest QoreStor definitely saved us money."
"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."
"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."
"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."
"Overall, it simplifies the management of backup and gives me a more secure feeling that my data is going to be available if I need to retrieve it."
 

Cons

"The only minor issues that come to mind are that, every once in a while, a hard drive will go bad. Also, the solution should be cheaper."
"We have not had a good experience with the IBM device."
"In Pure Storage FlashArray, the area with room for improvement is local MFA login."
"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."
"Self-backup is the only feature lacking in this solution."
"I want to improve the overall service level of the solution."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"The only thing is that we've had to upgrade controllers a few times because we ended up wanting to use more stuff on here."
"However, hardware failures can impact the cluster, making it read-only."
"The troubleshooting feature of this solution needs to be improved, to allow organizations to fix issues without having to contact the support team."
"The solution needs to provide better integration between this solution and all other kinds of systems."
"While there can be occasional issues with routing to the wrong region that lead to slight delays, it's typically business as usual."
"Dell has a very poor support channel in Taiwan. They sell the models directly to our enterprise customers and they don't have a very good vendor support system."
"The solution could be more cost-effective and secure."
"The deployment is not easy, and some expertise is required to configure the virtual data center and replication groups."
"We have had issues when the ECS is expiring or the NetBackup is expiring images."
"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."
"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 setup of the software is definitely not the easiest thing in the world."
"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 management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
"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."
 

Pricing and Cost Advice

"We have seen a reduction in total cost of ownership."
"It's a good price point and it's a solid product for the price."
"The Evergreen Storage subscription is great, because then I get new controllers every three years."
"I would rate it a seven out of ten for pricing. It could be improved."
"We would like them to improve the pricing, so we could put them to use some more product, like backup or long-term storage. In the future, if the price goes down, then we could buy different types of products."
"The price was more favorable than Dell EMC."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"Pricing is moderate. It is neither cheap nor expensive."
"If I remember correctly, Dell ECS is an appliance, so if you buy Dell ECS, you also have to buy the hardware, while IBM is standalone software, so you can buy IBM as software only without needing to buy the hardware. On a scale of one to five, I'm rating the pricing for Dell ECS a four."
"It is an inexpensive product."
"The price of Dell ECS should be reduced."
"The product is quite expensive."
"Dell EMC ECS is too expensive."
"The charges for this solution are made in blocks of models, which are purchased depending on what features an organization requires."
"The price of Dell ECS should be reduced."
"We are not paying for the license at this stage."
"Its pricing model is very attractive. You have one price, and you get everything from QoreStor."
"The cost is per terabyte, and overall, the cost was reasonable when compared to some competitors."
"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 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."
