We performed a comparison between Dell Unity XT and Pure Storage FlashArray based on real PeerSpot user reviews.
Find out in this report how the two All-Flash Storage solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The high availability of the product is the most valuable feature."
"The most valuable features of Pure FlashArray X NVMe are its superior performance compared to other flash tiers, as well as its ease of use, with an intuitive user interface that is simple to deploy and use."
"It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The latency is good."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"The technical support is very professional and provides quick responses."
"I like the easy management with the new Unisphere management and the HTML5 interface."
"It can be simple to deploy, the standup time is quite quick. The interface is quite quick. The terms are simple, intuitive, it's similar what was there in the VNXE before it. It's very simple to navigate and administer from the console."
"A lot of the Unisphere interfaces are greatly improved in terms of monitoring capabilities, alerting, and ease of use. Setting up the storage and the file system are all just a few clicks away."
"The performance combined with the gig-per-dollar value is a combination that is superior to other storage options."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"It's very reliable. I have not had an issue with Dell EMC Unity."
"Real Unified Storage (Block, File, VVols) in a unique 2U hardware."
"The initial setup is very straightforward. You simply plug it in and turn it on."
"Redundancy and the fault tolerance of the platform are the most impressive."
"Having an intuitive user interface to get things running is great."
"The speed is one of the most valuable features of Pure Storage FlashArray."
"Scalability is one of the best features. You can quickly add more. You can swap out the drives with larger sizes, you can add more shelves. All of that is perfect - the whole concept of keeping it modular..."
"The all-flash disc is the most valuable feature of this solution."
"We have tons of capacity on it."
"It has been very stable. I have not seen or heard of downtime storage issues after moving over to it."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"I'd like to see the product implement active replication for vehicles such as VMware."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"We need better data deduplication."
"In terms of what needs improvement, the dashboard and management could be simplified."
"There is an issue with data duplication occurring on the flash memory. It should be improved. Timely updates and upgrades to the latest versions would be great."
"It should be lighter. It takes up a ton of rack space. It would be nice to have a smaller footprint."
"We've got an ongoing issue with a Unity where some power supply fans spin up. We've had a whole bunch of hardware changed as a result but I still have an open SR which has been a struggle. It doesn't seem to affect performance, but it's something that we're hoping the engineers can resolve. Also, we had some issues with an upgrade where we can't manage a device, after the upgrade. So we had to have a ticket in for that."
"We've also encountered an issue when it comes to migrating to compressed LANs on the Unity, and during the Storage vMotion. It appears that the compression algorithm is overwhelmed, and when it becomes overwhelmed it just stops compressing and writes the raw data to the destination. We later copied internally another Storage vMotion to another compressed LAN and achieved much higher compressions on that internal copy. It would be really nice if there was a way to automatically throttle, as a part of a Storage vMotion, to say, "I want to gain the maximum benefits from the compression algorithm, so throttle back the Storage vMotion to implement 100 percent compression.""
"Inline dedup compression security is coming up as an issue, encryption, etc. is key for our customers. If we could have more ways to do software-based encryption, those are the features customers are asking us for, as well as replication."
"It would be great if the solution could integrate an NVMe disk."
"We noticed in the last release of code that there were some inefficiencies around getting our data efficiency up in terms of dedupe and compression."
"In terms of what could be improved, I would say the deduplication part, because for large deduplications, you need an extra appliance to do it in order to avoid having problems in performance. I think that could be improved, because everything should be included in the product, not with an appliance from the outside."
"Self-backup is the only feature lacking in this solution."
"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."
"I would like the ability to swap out the network adapters into it. So, without taking out the whole controller, I would like to be able to swap adapters. This would make things easier."
"The file functionality could be better."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"The price of this solution could be improved."
