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.

Shared storage capabilities provide enterprise value with good reliability
Amazon FSx is more costly compared to other storage solutions like EBS or EFS. The auto-scaling feature should be improved, as it currently includes downtime. I need to manually increase the storage, which is not ideal. Integrating FSx with Windows Server is challenging; it's a long process involving Active Directory (AD) setup and synchronization.
Alan Powers - PeerSpot reviewer
HPC CTO at a manufacturing company with 10,001+ employees
Stability-wise, a device that has been up and running for years
The failover capability and resiliency are some of the solution's valuable features. The big thing is resilience because it has richer coding in it, so multiple devices can't fail. Also, one can still access a number of CBoxes that can allow one to access their file system. Once a device fails, it fails the transparency of the end-user, and it just starts using another resource. The encryption capability, the snapshots, along with a whole bunch of features make the tool valuable. VAST Data keeps adding more and more features all the time.

Quotes from Members

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

Pros

"It's very fast, easy to use, and the cloud-based management is good."
"Firstly, dedupe is the most valuable feature, hands down, and simplifying storage is also a big win overall."
"It saved a lot of space, as far as physical space in our data center."
"With Pure Storage FlashArray we have been able to deploy several thousand VDI servers, virtual machines, very quickly and efficiently."
"The support from Pure Storage Flash Array is amazing."
"Pure Storage has the right business model and will be around for a long time."
"It is easy to manage. You don't have to have the same people who used to manage the Dell EMC arrays because the solution is more intuitive."
"It is very easy to use."
"We used it for disaster recovery perspective behind a number of resources, like batch services and RDS."
"FSx operates as an independent service, not tied to any server, which eliminates dependencies between applications for storage."
"I rate the stability of Amazon FSx ten out of ten."
"The shared storage capability is highly valuable."
"On a scale of one to ten, I would rate Amazon FSx a ten."
"The solution is useful for machine learning and scientific applications, including computer simulations."
"This has been one of the most reliable storage systems that I have ever used."
 

Cons

"For scalability, I rate it a six out of ten. We reach a limit. We never reached this limit, however, the architecture allows you to go until a certain size, and after that, you have to buy another array."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"The price of Pure Storage FlashArray could be better."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"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."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"The solution is not cheap. It's much more expensive than DataCore."
"A direct FTP feature would be beneficial instead of relying on transmission services."
"I've been facing a challenge when doing a failover from FSx side. AWS console does not refresh within a half hour."
"From my experience, there are areas in Amazon FSx where more performance is needed, as they will be looking for higher IOPS."
"Amazon FSx is more costly compared to other storage solutions like EBS or EFS."
"The write performance could be improved because it is less than half of the read performance."
"The read/write ratio is an area in the solution with some flaws and needs improvement."
 

Pricing and Cost Advice

"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."
"The best features come included without any additional cost."
"The solution could be cheaper."
"The pricing is very attractive and it delivers performance for the money."
"While it comes with a higher price tag, this investment often translates to significant improvements in performance."
"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 Evergreen Storage subscription is a really cool concept. As long as we maintain our subscription, we will get new controllers every three years and really never have a forklift upgrade like we currently are doing. Just that future-proofing is an ease off of my mind to know that I won't have to do what I'm dong right now again."
"It is light years beyond anything else with the same price point."
"The lowest price I have paid is $370 or $380 per month, while the highest can exceed $3,000 per month."
"We acquired VAST Data as a one-time, capital purchase."
"Price-wise, VAST Data is not the cheapest, not the most expensive one."
