"The system has dual controllers but does not have a high level of resiliency built-in."
"In the configuration, which we brought in or tested it in, it has a very limited config as far as the array goes. That said, it still did more than our anticipation."
"It was not proactive communication."
"We need to add more storage in Pure Storage FlashArray with the cluster mode activated for us to have better performance."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"Self-backup is the only feature lacking in this solution."
"The price could be better."
"The initial setup of the product is complex."
"Licensing costs could be reduced."
"This product has some scalability issues. Before you can get support, you have to look for the service tag number on your product which could make it difficult to access support."
"It is expensive, and the pricing could be better."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"This is a tier-three solution and it gives us what we need for archiving and backups."
"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."
"Having more artificial intelligence tools built into the solution would be a great benefit. This would allow us to see more about the workloads and higher visibility, such as performance degradation."
"If we have some complicated issues, you have to use the command lines interface. Not everything is possible to be fixed in the GUI. This is a drawback, that some things have to be fixed via command-line interface and should be able to be done in the GUI."
"The only thing that can be improved is the cost."
"The updating process could be easier."
"The upgrading process could be simplified."
"This product is very expensive."
"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."
"Lacks an integrated backup solution."
"It could have some automation. We haven't involved ourselves in a lot of automation around the vSAN environment capabilities. We're still running it using a very traditional setup. So, there could be some plugins to automate it using third-party environments, such as Jenkins."

Reviews from Real Users
Pure Storage FlashArray is a highly effective piece of storage technology which stands out among its competitors for a number of reasons. Two major ones are its overall robustness and the value that it offers by way of its reliability and ease of use. It provides users with many valuable features that allow them to maximize what they can do with this solution. Pure Storage FlashArray’s reliability and ease of use make it a highly valuable solution.
PeerSpot user Prabakaran K., a technical consultant at Injazat Data Systems, notes the robustness of this solution when he writes, "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."
PeerSpot user Jason D., a cloud solutions architect at a tech services company, notes three features that make this solution valuable when he writes, "We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
