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.

Utilizing network data sharing effectively with cost considerations
What should be improved in Amazon EFS (Elastic File System) is the costing, as it should be reduced, but that depends on Amazon. To be frank, I don't have much comparison as we don't have a good volume. We have very little volume on the EFS (Elastic File System), which is why I couldn't do much cost comparison. Currently, I'm not aware of the exact costing, but previously I found that the costing was a bit high.

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

"The cost of Pure FlashArray is a bit high compared to peers, but its sustainability and features justify the price."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"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."
"The connections are a lot faster than what we had in the past. One InfiniBand does what we did on all of our Fibre Channels."
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"I recommend this solution for production because it has good performance and capacity management."
"Having an intuitive user interface to get things running is great."
"Pure Storage FlashArray is simple and easy to use. It offers protection when removing devices. It has the ability to undo deletes."
"Amazon EFS (Elastic File System) is an excellent service that provides a serverless solution with unlimited storage and easy configuration."
"The solution is quite stable."
"We are not that big of a cloud user. We just use it for the storage of our bytes. The most valuable aspect is the storage."
"We need our storage to expand based on demand but storage is a bit costly, so we start with a smaller amount and, as we grow, we use EFS on demand and it manages our costs."
"The solution is scalable."
"The platform is highly scalable."
"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."
"Elastic File Systems allow me to share data, provision, and manage capacity and performance in AWS."
"Quest QoreStor is very stable compared to our previous solution."
"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."
"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."
"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."
"The features we use for the data deduplication are nice because we're able to back up a much larger amount of data, yet it doesn't necessarily take up that much data on the devices."
 

Cons

"I think replication is one area that still needs improvement."
"It is not possible to create a cluster on top of multiple arrays."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"Currently, the solution fails to support file screening."
"I recognize it's a difficult challenge, but I would like to see them make the pricing more reasonable."
"I would like to see them develop the ability to integrate with more AWS services. There are increasingly more and more services coming out from AWS but there are also certain constraints where we can't move everything over to a cloud as well. We would like for things that are on-premise to be easily integrated with AWS."
"FlashArray could improve on the administrative side. For example, when you need to upgrade the boxes, we can't do that ourselves. We need to open a ticket with support and have them do that for us. You don't need to be on the call with them. We tell them we have a slot that we want to upgrade, and they send us an email when it's done."
"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."
"The platform's connectivity could be improved to be more comparable to S3 buckets, which offer better API availability."
"Its deployment process could be faster while installing the Python package directly into the environment."
"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."
"It could be better in connecting with Windows Server instances."
"It should be simplified. There are people who don't have cloud experience. It should be storage that we are able to just connect to."
"Specifically, when it comes to the file system for the learning system, we encountered performance issues with both Azure and AWS."
"EFS could be improved by including a one-click setup."
"The initial setup requires prior experience and technical skills."
"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."
"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."
"They need to increase their maximum capacity. Other than that, they're doing a pretty good job."
"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 ransomware protection of QoreStor could use improvement."
"The air gap feature is something I'd really like to see in QoreStor."
"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."
"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

"We purchased a license to use this solution and we pay for the storage ourselves."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"There are no fees for licensing. The hardware is paid for only once."
"The solution could be cheaper."
"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."
"We have seen a reduction in total cost of ownership."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"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."
"The product's price depends on the services and the size and capacity at which it is used in a business environment."
"The product charges are based on the amount of data stored."
"I would rate the pricing 7 out of 10."
"It has flexible pricing. You are charged based on your storage."
"Amazon EFS (Elastic File System) offers a pay-as-you-go model, so whenever you use its services, you need to pay."
"The solution's price is mid-ranged."
"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."
"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."
