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.

Managing data protection has become consistent and analytics now drive reliable performance
The most valuable features I find in Dell Unity XT include its robust performance and reliability. My thoughts about its in-line deduplication feature are positive. I would assess the value of Dell Unity XT multi-cloud support for my IT environment as highly beneficial. I do utilize Dell Unity XT data protection features. These features have assisted in ensuring data integrity by providing reliable backup and recovery options. Dell Unity XT integration with VMware helps scalability and availability through seamless operations and enhanced performance. My opinion on its Cloud IQ analytics is that it delivers insightful data that aids in operational efficiency.

Has a fantastic feature-set and works well with workflow solutions
I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution. It would be a homogeneous environment. I think it would be definitely a better option for customers considering other all-flash storages. It would be better if you consider a solution from Oracle, from the database studio, the storage part. I would rate it an eight out of ten. To make it a perfect ten, in the next release, I would like for it to be NVMe compliant storage.

Quotes from Members

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

Pros

"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"It releases those to new teams within minutes at a very small storage cost amount."
"It saved a lot of space, as far as physical space in our data center."
"The job of support for the storage engineers dramatically changed. We know more quickly the automation of the provisioning. We can now focus on things that bring more value to the company than just managing storage."
"The most valuable feature is its speed."
"The GUI is very easy to use and intuitive."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"The solution is stable with low vulnerabilities."
"As far as how Dell EMC Unity XT has performed, I don't think I've ever seen latencies above 10 milliseconds, unless it was something that wasn't the array that was messing up."
"The All-Flash models are pretty fast for the vast majority of our remote workloads."
"There are some alternatives, but what we've found, working with our partners, for mid-range storage it's probably the best one you could choose."
"We use the solution for site recovery manager, DR, and endpoint penetration."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"Given the performance of the Unity array, we've been able to do more with less."
"Purchasing; We worked with a sales rep to purchase our Unity."
"The most valuable feature of Dell Unity XT is data duplication. Additionally, the management interface is simple, and is not a hassle using it. You don't need too much to learn or to be familiarized with it."
"I would suggest, if you heavily depend on the Oracle solution from the database you should consider Oracle All-Flash because, from my understanding, it is from a single OEM, it's a single solution."
"It's actually shaking hands with the workflow solutions much better than any other storage."
 

Cons

"It was not proactive communication."
"We haven't seen ROI yet."
"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."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"The integration capabilities could be improved."
"I would like to see them add Storage Groups, like we have had in Clariions and VNXs."
"Dell EMC's competitor has a clustering technology. In the next release, it would be nice if they could build that into the product."
"We have had a lot of issues. We've got massive issues at the moment with IBM AIX, it's not stable, we have a lot of disk errors, production crashes sometimes, and that's not good for a retailer."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"The price of this product can be more cost-effective."
"Unisphere Central is not so useful as we expect. This will provide a centralized management of our arrays, but it ends up giving you only some numbers and figures for you to report to your management."
"It is expensive, and the pricing could be better."
"We have only used tech support to replace drives that have gone bad. But our experience has not been so good."
"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."
"Technical support, as a whole Oracle organization is very process-oriented. So sometimes it doesn't allow you to understand the customer's specific requirements because they have their own parts, practices, and policies."
 

Pricing and Cost Advice

"We have a seen a reduction in TCO. It is definitely a cost-effective solution for us. We have seen ROI."
"The solution could be cheaper."
"The price, in general, is around $100,000, however, I know it costs more."
"The guaranty that Pure Storage provides when you purchase it doesn't meet the overall capacity needs to provide extra storage, if needed. Thus, it is not meeting our expectations."
"When we bought the unit, we bought per capacity. So, the licensing is per capacity, and the only thing that we have to buy every year or every three years is maintenance. Included in that maintenance is the upgrade of the controllers every three years at no cost to us."
"It is light years beyond anything else with the same price point."
"Pure Storage FlashArray's pricing is very competitive."
"It is cost-effective because after buying a subscription, they provide a service to upgrade hardware for free. They are providing so many features. When you consider the features provided, it is cost-effective."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"From a pricing perspective, this solution is comparable to others on the market."
"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."
"It is priced at around or under $50,000."
"The pricing is reasonable. We're using the Flex on Demand pricing. It's really good for us when we pay for what we use. It made it easy to get it inside since it's an OpEx and instead of CapEx expense."
"The solution is very expensive."
"It's the performance combined with the gig-per-dollar value. That combination is superior to other storage options."
"Pricing is as high as it has ever been for EMC."
