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.

Good price-performance ratio, provides simplified provisioning and management
We use this solution for provisioning and management The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption. The exterior display needs to be improved. Sorry, I like the blue lights the competition has, but maybe we can see green led lights…

Quotes from Members

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

Pros

"Everpure FlashArray is very user-friendly, easy to learn, and makes it easy to identify issues while providing more redundancy on both the controller and host sides."
"My advice to people who want to implement Pure Storage FlashArray is that it's a good NVMe solution, has a lower response time, and also good for entry-level storage purposes, e.g. small offices, small to medium-sized business, etc."
"All my customers are pretty happy with most Pure Storage solutions."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"We have looked at all of the platforms, and to see what Pure was able to do within a PoC environment meant that we never turned back our PoC environment."
"The management features are well organized and they have a very good dashboard."
"Having an intuitive user interface to get things running is great."
"As we needed to grow in capacity, we were able to do so without increasing footprint by replacing smaller devices with larger ones."
"Using this product has helped us to improve the security of information."
"It's easy to use, easy to manage, easy to troubleshoot, and the process support is good."
"We're using Dell EMC Unity as our primary storage for our production and for our DR site, we've had no performance issues with it whatsoever and we're using it for everything."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended."
"This product does bring a ROI, as I have seen it helps them to protect their investment since it is future-proof and scalable, so they don't have to change products every year or so."
"The most valuable feature is the dynamic cache of this product. It is very important. We have the physical cache and we can boost this cache using disks. All the products are mainly flash now and this is one of the main characteristics which our customers like."
"The Unisphere management interface: We are very familiar with it. It manages all the EMC devices that we have. Management is easy because it is part of Unisphere, which is self-learning."
"This solution had the best cost and it was easy to work with the Vendor."
"The most valuable features are simplified provisioning and management, de-duplication, and built-in encryption."
 

Cons

"I would prefer that they lower their pricing."
"The interface lacks the same level of control as some other arrays I've used."
"I would not say anything because we still do not use Everpure FlashArray fully."
"I wish they could add more of a monitor on the machine itself so you don't have to rely on a KVM or something to look at the display, such as an onboard diagnostic display."
"I would like some form of QoS implemented. As a service provider, it would be beneficial to have it."
"Pricing could be better in comparison to other solutions."
"Self-backup is the only feature lacking in this solution."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"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."
"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."
"Perhaps if they added more 10GB ports to the back of the system, so you have more IOPS out of the box itself to the network, that would help."
"Our request to Dell EMC for improvement was in the reporting and monitoring areas. Dell EMC built up a cloud ID so that we could see the overall storage numbers. We needed to have the proper KPIs to be able to see and manage things."
"The only room for improvement I can see would be a faster lead time and lower cost."
"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."
"Compression and block deduplication on non-all-flash solutions."
"For the upgrade from the old system to the new system, if there was a better way to integrate them so I could easily move the data without working all those nights and weekends, that would be nice."
"The exterior display needs to be improved."
 

Pricing and Cost Advice

"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."
"Pure Storage has not helped us to reduce our licensing costs."
"Pure is typically more expensive than everyone else. You get what you pay for, but I have lost deals to similar solutions because of pricing. They include everything, and that's another positive about Pure Storage. They aren't trying to nickel and dime their customers for different features. It is all included in one price. The license is by capacity, and the price depends on the capacity and the discount we're getting from the vendor. You get the SKU of the physical appliance, support, and maintenance, and that's it. You're licensed for whatever feature they offer. It is all rolled up into the price of the appliance."
"The price is very reasonable when compared to other solutions."
"For pricing, you have to take into account their performance on deduplication and compression in a $/GB comparison."
"You get what you pay for. It is expensive, but it really works."
"Once you purchase Pure Storage FlashArray it is all-inclusive, you receive all the licenses needed."
"It is not the cheapest one out there. We're paying yearly, but I'm not 100% sure."
"Our CAPEX was close to $42,000 and operating costs are below $1000."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"Obtaining a warranty is easy."
"We purchased a five-year warranty."
"The price is up a little bit from what we used to pay so I'm hoping that it's a little bit of a better system than the VNXe was. But I still think it's a good value. It's new, so I'm sure there's room for the pricing to drop."
"The price of Dell EMC Unity XT is higher compared to other solutions. The price should be less expensive."
"This unit is one of the cheapest storage all-flash arrays in the market and it does well for what it is intended. It can be combined for both file and block storage."
"It is shipped with all licensed, included for this product range, no need to buy additional licenses"
"This solution has a good price-performance ratio."
