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.

Ease of implementation and robust performance enhance multi-OEM support experience
We are limited only to hardware replacement, not administration tasks. We work on AMC products through Annual Maintenance Contracts. We provide support up to the 680 model. The XT680F is a newer model, and we support from 380F to 680F. The FlashSystem 8000 series is all-flash, and there is also a 5000 series flash model. We can compare IBM DS series, including the 8000 series for recommendations. For NetApp, we can recommend the FAS 8000 series.

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 is the SAN backbone for our company."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"This solution has improved the way our organization functions through its reliability and consistent platform for storage and has helped us to simplify storage because the management tools make everything a lot easier."
"We were previously on legacy storage systems, and after moving to Pure Storage, our stability and performance both drastically improved."
"Like I tell everybody else that I deal with, if you want to focus your time on doing more valuable things for your company, and you deal with storage on a day-to-day basis like I do, the best thing you can do is put Pure in your environment."
"I have seen a huge increase in speed and performance on our databases."
"The solution has probably reduced my power use substantially."
"There is no comparison performance-wise."
"The most valuable feature of Dell Unity XT is the GUI, it is very good. End users can manage using it. Additionally, the documentation is of high quality and it integrates well."
"What they really like is the easy licensing now - Dell EMC has caught up to a lot of their competitors - based on not having to charge for everything, and they can get everything in one bundle."
"The Unity XT box is very strong. It doesn't break. The MTBF time is very large so you don't have to worry about faults or outages in your operations."
"It is very user-friendly to read and determine the exact problem, unlike HP where different tools and L3 team support are needed."
"At the moment we are using it with VPLEX, which is a very big advantage for us, and although we don't use many of Unity's functions, it provides good provisioning that allows us to save space, and with the all-flash systems it is quite fast."
"For our environment just having a solid, running box is really sufficient."
"It is easy to scale, maintain, and manage."
"It has saved us time when provisioning new storage, so we're trying to automate that process."
"It's actually shaking hands with the workflow solutions much better than any other storage."
"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."
 

Cons

"Self-backup is the only feature lacking in this solution."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"Pure Storage had operational challenges between 2016 to 2018, impacting perceived reliability."
"Reports of performance and LUN utilization could be improved."
"The data reduction that we had initially anticipated when we bought Pure and we moved over is way lower than the expected reduction."
"The pricing needs to be improved as they offer very high budgeting prices. Searching is a big challenge in Pure Storage FlashArrays, especially when trying to restore a VM."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"We'd like to see a cheaper version of an all-flash array in that footprint."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"We would like an AI feature that would protect the backup and minimize the consumed space so we can maintain the quality of the backup."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"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."
"There could always be improvements to the UI."
"Stability is the problem. We've had stability issues with it."
"This product needs to have better integration with enterprise backup solutions and archiving devices."
"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 price is reasonable."
"Cost-wise, I imagine that the product's price would probably give you a nosebleed if you were a younger company."
"We have seen a reduction in the TCO, because Pure Storage is partnering with Belfrics. This partnership reduces our latency and space."
"While more expensive than NetApp, Pure Storage FlashArray offers superior performance that often justifies the higher cost and adds value overall."
"The cost has room for improvement."
"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."
"The price, in general, is around $100,000, however, I know it costs more."
"The price was slightly higher than others, but competitive, if you consider all the other features that you get from it."
"This solution is a good price for what you get."
"The price of Dell Unity XT could improve. However, it is a one-time purchase."
"For costing, you have to have a budget in mind because SANs can be fairly expensive and EMC offers a wide range of products."
"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."
"The license is not required, but we must renew the support every year, every two years."
"It is priced at around or under $50,000."
"There is an annual charge for the license of this product. It has better pricing than its competitor: Pure Storage."
"The pricing of Dell Unity XT is good."
