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.

Performance and interface improve data processing speeds but require complex configuration
The most valuable features of VMAX are its performance and GUI interface. We have seen significant improvements in technology over the last four to five years. The snap feature, along with deduplication, has notably enhanced our data processing speeds. We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution.

Quotes from Members

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

Pros

"When we needed to replace the other arrays, we went straight to Pure and life-cycled them into Pure in every segment we have."
"The management is simple in Pure Storage FlashArray."
"The most valuable features in Pure Storage FlashArray are deduplication and active cluster."
"It's reduced our overhead management time on storage, since it is so simple to get in and just provision a volume, present it to the host, and then you are done."
"Because of the encryption, we have different storage and the encryption can go over both, therefore we are NCA compliant."
"Technical support has been amazing."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"On a scale of one to ten, where ten is the most comfortable pricing, I rate the solution a nine out of ten."
"The most valuable feature is that the solution is a hybrid system, so you can do both block and file storage."
"The implementation went smoothly."
"If you're looking at a flash-based system, one that you want to work and not to have to play around with it - to be sure it's working all the time - Unity is definitely a step in the right direction for any company, going forward."
"We are replacing legacy hardware and hardware that is going out of support, and we are consolidating two or three systems into one."
"The initial setup is very easy. I would rate my experience with the initial setup a nine out of ten, with one being difficult and ten being easy."
"It gives me the flexibility with its ability to replicate to itself and the ability to use the Dell EMC Cloud as an option. That's always sitting there and waiting if we need it."
"The most valuable features include snapshots, Thin Clones, and deduplication and compression."
"It’s helped with the overall stability of our VMware environment."
"It works very well."
"The ransomware protection feature is housed in a separate unit, specifically addressing the top twenty most critical threats."
"The most valuable features of VMAX are its performance and GUI interface."
"The snapshot feature has been precious for our testing processes, application development, and managing testing environments due to its efficiency and ease of use."
"We haven't experienced any outages or core-level issues in the last ten years, making us comfortable with the storage solution."
"The product's initial setup phase was good."
 

Cons

"Pure Storage support could be a little better."
"The difference in pricing could become a problem for Pure because the commoditization of the solutions could lead to a different price being a problem."
"During heavy load situations with 100K IOPS on one specific port, it requires more granularity level for distribution."
"Areas for improvement would be the financial operations. In the next release, I would like to see a NAS protocol included."
"The integration capabilities could be improved."
"In the next release of the solution I would like to see Vormetric native block encryption."
"In some cases, we get into very in-depth conversations around the movement of specific data and, what's more, chunk sizes. The documentation lacked any description or information on that."
"The interface lacks the same level of control as some other arrays I've used."
"It might be nice to have more integrated features instead of having everything as a separate module, like the networking. The networking is attached separately in the back. It would be nice if that was more integrated with less ports."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"It's not as reliable as it should be, I think it was probably released a little early. We've had production problems with customers, and there are still some challenges at scale as well. Compression is a problem for the system. Once you enable dedupe and compression, the performance of the system, the capability, halves... It has to be right-sized and sized for compression, but even with that, because there are only two storage processors, you're ending up at almost 40 percent usage."
"The price of Dell Unity XT is reasonable. However, if you are buying a custom solution, it can come at a considerable price."
"In the management interface, you can only create one LUN at a time."
"Improve the administrative user interface so it is easier to work with. Currently, a simple task, such as removing a host from 100 LUNS, takes a lot of time. If they could improve LUN to host model to be more like the EMC VPLEX, for example, it would be great."
"Scalability of this solution could be improved."
"This product lacks deduplication and compression at the current version 4.1.0. LACP is not available for iSCSI either."
"There is room for improvement in the centralized administration."
"Improvements are needed in both partition recovery and scalability."
"We encountered some challenges during large data migrations that could be addressed for smoother transitions."
"The scalability of VMAX is somewhat limited, especially in terms of cache scalability. We've had to procure additional engines to address this limitation."
"The configuration part of the product is an area with certain shortcomings where improvements are required."
 

Pricing and Cost Advice

"The price of the solution can be a bit expensive. There is an additional fee for support."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"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."
"We implemented Pure Storage FlashArray nine years ago when it was new to the market and obtained it at a preferential price."
"Its price is almost double than any other flash storage solution."
"When you are paying more than you were paying for the storage space, you'd like the cost to be less. If they could get into the spinning disk kind of cost, that would be it."
"The pricing is an issue. However, being all-flash, it will always be sort of expensive."
"There are no licensing fees aside from the support."
"The return on the investment was simply speeding up our entire vSphere stack, which allowed our developers and engineers to get their workloads done faster and simpler. We were experiencing VM snapshot times of 45 minutes to two or three hours, and it shrunk it down to under five minutes."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"Licensing is fine. We worked with a sales rep to purchase our Unity."
"As far as licensing goes, I love how VMware works with Dell EMC Unity. It's great. They work hand in hand. They have made it so simple."
"Currently, we buy directly from Dell EMC. We've tried going through resellers before, but we've found that if we go directly through Dell EMC, we get a good a price from being with the government."
"Compression is making a difference towards the amount of hardware that we need to purchase."
"This solution is a good price for what you get."
"Its biggest valuable feature is its price point for the amount of storage and performance you get. It's a sweet spot. It's cheaper than the other SANs out there, but performs well enough. It fits that nice, middle-ground portfolio."
"The price falls within the mid-range, neither inexpensive nor high-priced."
"It is not a cheap product."
