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.

Security features impress while response times need improvement
We use cloud storage security, which is a virus scanner for their infrastructure, as a new addition. Other than that, it focuses on serverless features, such as Lambda and Aurora SQL server databases. CSS cloud storage security, which is offered by AWS, is integrated into our system. It functions as a virus scanner that monitors whenever any incoming file arrives. The AWS service is excellent security-wise, and I have seen some other features besides security, such as automatic scaling that helped us significantly. Regarding integration, it provides us with the benefit that our data is kept within our account only.

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

"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology."
"The GUI is very easy to use and intuitive."
"They have a very good support system, and the GUI is also very intuitive."
"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."
"Pure Storage FlashArray simplifies maintenance and management with its intuitive GUI, making storage allocation and other processes easy to understand, even for beginners."
"The Direct FlashArray stands out as one of the best features in the market. The Pure1 storage management lets us see the details about utilization and everything else for all 40 storage boxes in one place."
"The best features of Pure Storage FlashArray are its ease of use and user-friendly interface, and the performance allows all types of services to be visualized from a single point of interface, making it more robust and user-friendly."
"I would definitely suggest this solution to a colleague because of the ease of use."
"Amazon EFS is extremely stable, as it is managed by AWS."
"I appreciate Amazon's extensive range of services, which makes it a favorable choice."
"Amazon EFS offers the flexibility of scaling as needed without requiring pre-provisioned storage."
"The solution's technical support is good."
"Amazon EFS offers the flexibility of scaling as needed without requiring pre-provisioned storage."
"Elastic File Systems allow me to share data, provision, and manage capacity and performance in AWS."
"Its elasticity and flexible pricing are the most valuable. For Amazon EFS, you are charged based on the storage. It is also very fast and stable with a very simple and intuitive interface."
"The product's initial setup phase is easy, as per the configurations."
"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."
"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."
"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 us to reduce our backup storage requirements on-premises, and we've been using the same devices for quite a while, so it lets us keep using them as opposed to having to rip out all that hardware and create a new on-prem solution."
"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."
"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."
"It integrates with various backup software solutions, which makes it compatible with existing backup workflows and processes."
 

Cons

"Pure Storage can improve FlashArray by providing more logging visibility to customers. Currently, there is no log visibility."
"The one major gripe I have is that there is no snapshotting enabled by default on the SAN."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"I would like to migrate to the cloud in the future and know how that would actually work with this product."
"It's too early to tell if we've seen a reduction in total cost of ownership. The solution is expensive."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"Elastic File Systems can be expensive due to the nature of data transfer costs, using services like SSTP, and potentially being costly in a rate-shift context."
"The initial setup requires prior experience and technical skills."
"Amazon EFS is more costly compared to other storage options available from AWS."
"A notable limitation of Amazon EFS (Elastic File System) is that it does not support Windows."
"It could be better in connecting with Windows Server instances."
"Specifically, when it comes to the file system for the learning system, we encountered performance issues with both Azure and AWS."
"Their response was not prompt, and it took them a while to figure out solutions. While the time to respond was good, the time to resolve was not optimal, as it took more than a week."
"EFS could be improved by including a one-click setup."
"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 need to increase their maximum capacity."
"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."
"Overall, I am happy with this solution, but a way to export configuration settings would be beneficial."
"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."
"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 management interface is in need of improvement. The graphical user interface (GUI) for the web management tools appears clunky, and not super intuitive."
 

Pricing and Cost Advice

"I think that the pricing is less expensive compared to other standard products in the market today. Even the support contract and maintenance services cost less when compared to market-leading products like EMC."
"You can pay extra for Evergreen support, which gives you free upgrades when new features are introduced."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"All storage is expensive so any price improvement would help."
"The price of the solution can be a bit expensive. There is an additional fee for support."
"In the beginning, we saw that the price is not very good. When we made some compilations about the deduplication and the compression and what the equipment does, including the differentiation of upper management of the storage, the price was not so bad. However, in the beginning, the price was very difficult to justify."
"The price is reasonable."
"Pricing is moderate. It is neither cheap nor expensive."
"Amazon EFS (Elastic File System) offers a pay-as-you-go model, so whenever you use its services, you need to pay."
"The product charges are based on the amount of data stored."
"The main challenge with EFS is its cost, which is slightly higher compared to EBS or S3. For one GB or ten GB of data, S3 is much cheaper. EFS could cost around $30 to $50 per month for similar usage."
"It has flexible pricing. You are charged based on your storage."
"The product's price depends on the services and the size and capacity at which it is used in a business environment."
"I would rate the pricing 7 out of 10."
"The solution's price is mid-ranged."
"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."
"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."
