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

"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"Whoever is using Pure Storage is happy with it, including the latency and everything, and we have not received any complaints related to Pure Storage throughout the four years I have worked here, which is really great."
"It saved a lot of space, as far as physical space in our data center."
"Most of the problems that we had in the past with the performance in IOPS have disappeared. It has been a great improvement for our customers' services."
"The management features are well organized and they have a very good dashboard."
"The best features Everpure FlashArray offers are the speed and dependability, which are the main features that we get from Pure; it is faster than its competition, and we do not have any documented downtime from it ever."
"From the performance that I've seen, the simplicity of how to use it, the responsiveness, and customer experience, it is one of the best companies that I have worked with so far."
"It makes things ten times easier."
"The product is easy to use and configure, and the support is also superb."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"EMC is known for its reliability This product is good It is easy to install and maintain It operates with low maintenance and manpower costs"
"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."
"It's easy to manage. We access it and manage it through Unisphere and have had no issues. We're able to provision storage, create consistency groups, create RDMs for our virtual machines. Creating it through Unisphere, it automatically adds the data store on the VMware side and rescans the LUNS. We just have to add and configure the storage in one place and it takes care of everything, which is very handy."
"Block compression on F Models or in flash pools allows us to almost duplicate the available space on the array; more space for less money, everyone likes this."
"They find the performance amazing from what they're coming from."
"The stability is good, and we are very happy with the Unity; it does what it says it does and it performs, so you never have performance problems 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

"The price could be better."
"We did have one hiccup with the integration of vCenter. When we were installing Pure Storage, we were using vCenter 6.7, which defaults to the HTML5 Web Client. The current plugin for Pure Storage doesn't show up in that client at all. You have to go and use the legacy FlexFlash client to see the Pure Storage plugin in vCenter."
"There was some complexity in the initial setup."
"Its price needs improvement. Its price is almost double than any other flash storage solution."
"The interface lacks the same level of control as some other arrays I've used."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"I want to improve the overall service level of the solution."
"The higher education moves slowly. We are still looking forward to implementing the full list of existing features."
"The technical support sometimes takes three to four days to get hardware to facilities. I would rate customer service four out of ten."
"Support and licensing are big things, in the end, that needs improvement."
"In future releases, I would like to see automatic upgrades from one to the next, when this system is coming out and the next one is coming in; more akin to what Pure Storage is doing. That would be really helpful."
"Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature."
"Dell Unity XT’s price needs improvement."
"If the product could only send alert notification via SMS, it would be much better."
"In terms of what could be improved, I would say its capacity and its connection."
"We have had some downtime. Nothing is perfect. Unity’s have had some code-release problems, versions that, from a compatibility perspective, had some glitches which caused an outage. But, given the amount of Unity’s we run, that has been fairly minor and it hasn't happened at scale or across all of our Unity’s."
"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."
"It has to be flexible according to the customer's requirements. It has to be aligned with the customer business and the business environment."
 

Pricing and Cost Advice

"The best features come included without any additional cost."
"The price of Pure Storage FlashArray is expensive."
"Pure is not a cheap product. It is not something that is inexpensive. But, the total cost of ownership tends to be lower than with other solutions, because you don't need a lot of expertise, you don't need a lot of training or very expensive engineers or very expensive consultants."
"There is always room for negotiation."
"We are finding the TCO of flash to be lower than SSD implementations."
"The price-to-performance is good. I looked at Pure about three to four years back, but the price-to-performance wasn't right for us. Now, it's right."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"Pure Storage FlashArray's pricing is very competitive."
"This solution offers great pricing."
"We looked at HPE Nimble but the price of the Unity XT was very good compared to the competition."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"The flexibility is important. We still have a lot of customers that have a use case for non-flash, yet you can also build the flash version as well."
"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."
"With the large Unity that we bought, it has saved us about one and a half rack space. That's our return on investment on our flash array. We also need less Fibre Channel connectivity."
"We have to apply for a license for each system."
"This product is cheaper than the EMC VNX solution. It is good for small businesses."
