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.

Quotes from Members

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

Pros

"It makes things ten times easier."
"The stability and performance are the best things about the solution."
"The most valuable features of Pure Storage FlashArray are management and administration user-friendliness, provisioning, and performance."
"The availability and ease of use are the big features."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"For VMware, it has been a humongous savings."
"Once we solved the data reduction and what Pure does we were hooked."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"Technical support is very good."
"It has reduced the latency in application and database reads and writes, which is of benefit to the business."
"When comparing them all in their strengths for implementation, the lifecycle of the product, and the support they provide, I would rank Dell number one, IBM second, and third would be Fujitsu."
"Stability has been pretty rock solid for us."
"We have integrated it with vSphere and SQL. There were no costs involved outside of our normal workload licensing, no costs that were specific to the Unity platform."
"I can't say enough about the Flex on Demand because it gives you the agility you need."
"It is lightning fast, low on power and heat, and has a small footprint with great performance."
"Our end-users are happy with the product, there are no issues."
"Lenovo ThinkSystem DE Series is cost-effective; there is no license, all of the features are bundled together, and you can renew the bundle with all of the features included."
"The solution is very easy to troubleshoot, it doesn't take long to deploy, normally comes with a three-year warranty, and has the most features if you compare it to other models."
"The solution is very easy to set up."
"We have been working with the solution for around a year and so far it has shown itself to be stable."
"The solution's initial setup process is easy."
"My advice to others is that this is a straightforward, detailed documented, and supported solution."
"Fewer features is not necessarily a negative as it leads to simpler operation and lower price."
"The solution is very easy to troubleshoot. It's one of the most valuable features. It also doesn't take long to deploy and normally it comes with a three-year warranty."
 

Cons

"With scalability, I have run into a little problem with our last upgrade. There were some undocumented limitations to the number of drives that our controller could run on. So, instead of putting in a new data pack as we had anticipated, we had to keep adding and removing to get up to the capacity that we needed to be. What should have been a one day process (or a few hours) turned into a month and a half process."
"The price of this solution could be improved."
"It is a bit expensive."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"In the next release I would like to see integration into other third-party player providers like Google."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"We would like to see more development on their Copy Automation Tool (CAT) for Oracle, as well as better integration for our customers running Oracle VM."
"One thing I'd like to see in a future release is integration between their main storage array and what they call their FlashBlade product; to be able to snapshot directly from the primary array into multiple different backup copies on FlashBlade."
"I would like the device to have the ability to pull down its own firmware. That would be a great thing."
"I haven't seen the roadmap for this solution."
"However, configuring it for the application is quite tedious because it doesn't have any built-in templates for different workloads."
"It is expensive, and the pricing could be better."
"Because we can do synchronous replication between the two sites, this made the setup challenging for this piece. They did not know how to set this up initially. We ended up having to do bidirectional synchronous replication."
"What I'd like to see is a little more detail on the networking side. I can go into where it's showing me the replication, but when I go into the network it just gives me broad-based information. I don't know which replication job is actually feeding it. I have to go in and rely on other apps."
"A customer had to buy VMX because Unity didn't have WORM."
"Data replication needs improvement as the future roadmap for RecoverPoint appliance is not there."
"There could be a snapshot feature in the solution."
"Its performance could be faster."
"In the next release, I would like to see more functionality. But, again, it is an entry-level product."
"The solution could be more scalable, although it suits our present needs."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration."
"The difficult part comes when dealing with the host. You have to enable multi-pathing and other aspects that are needed for proper configuration. I don't know if there is room for a more hyper-conversion structure to work with, but this would be easier."
"The solution could be more scalable, although it suits our present needs."
"It would be useful to have structured solutions replicated to other sites."
