Supports efficient storage management through volume snapshots and offers reliable non-disruptive upgrades

I have no specific improvements to suggest for Pure FlashArray X NVMe at this time. The performance statistics could be enhanced. I can see the performance statistics in the Pure Storage console, but it does not show the performance by 4K byte unit. It displays IOPS and bandwidth, but IOPS is about real use, and I want to know how many IOPS are currently running in 4K byte units. I cannot see that IOPS because most storage systems report their performance by 4K byte unit. I want to see Pure Storage performance by 4K byte unit to compare with other storage or other internal NVMe SSD.

Good customer service and support and suitable for large environments

It is very easy to install. Users don't need to remember anything while deploying IntelliFlash because everything will be taken care of by tech support. They can easily modify the installation or change the password with the help of the tech support. It is very easy to integrate IntelliFlash with other solutions. We have plugins that can be integrated with other solutions. It will require maintenance. It is the same as any other storage solution: updates and upgrades, firmware upgrades, and drive upgrades.

Customer needs are addressed effectively with collaborative sales and service support

Recently, customers have been asking for a cloud tiering option in storages. Some Dell storages do not have cloud tiering, which is an optional commercial feature. NetApp's FSA model 2750 comes with an inbuilt cloud tiering option. In the future, if Dell storages include this option, especially for Unity, it would help us target SME or medium enterprises for quicker closures and support the sales team.

Quotes from Members

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

Pros

"It has benefited my organization because it has reduced time to insights."

"After the testing, it was clear to us that the Pure FlashArray X NVMe was the easiest to manage and configure and had the best performance that we had seen in all the arrays."

"I use the tool for Oracle databases, Oracle virtual machines, and Oracle Linux databases. I'm on the storage side, not a database administrator."

"Its speed is superior to our existing Unity x00 model and it has performed substantially better than our x00 model and a little bit better than our x50 model."

"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."

"The best features of Pure FlashArray X NVMe include the volume snapshot capabilities, which allow us to save most of the storage space by volume snapshots periodically."

"Technical support has been helpful and responsive."

"It has good, reliable, and fast storage."

More Everpure FlashArray X NVMe pros

"Once we got this solution in there, we were able to get the reporting down from eight hours to under 20 minutes."

"Ease of Use: Someone can learn it in only few hours Performance: Easy Tier is doing miracles Data Compression: Up to 80% space reduction in the database"

"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."

"We have been able to realize storage space savings for our virtualization environment and it has reduced our electricity usage by reducing the number of disks needed for the virtual environment."

"Data Compression: Up to 80% space reduction in the database"

"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks Cheaper than pure solid state without needing to actively manage where the data is located."

"It provides a combination of all the protocols that you need, without losing deduplication and compression."

"The initial setup is straightforward."

More DDN IntelliFlash pros

"Provides good provisioning, allowing us to save space."

"The initial setup was very straightforward. Migration was smooth and configuration of the storage was quick and simple. The time needed to put it into production was less than expected, and data migration itself went without a glitch."

"One of the things that I like the most about it is how they have changed the Unisphere GUI, and how it is now HTML5."

"It hasn't missed a beat; we haven't had any issues with it whatsoever, speed has been great, it does everything we need, there has been no downtime, and with built-in redundancy upon redundancy I feel very confident with it."

"It's easy to handle for administrators and it's a unified system. It's not as complex as Celerra systems or CX4 Clariions to administrate. You can do everything with one GUI."

"I would tell a colleague this makes a very sound investment."

"The compression and deduplication that will be coming in version 4.3. With just those features, you're reducing the amount of data and the footprint on the hardware."

"Lately, the biggest use I've seen is around VDI and data migrations - migrating from the old VNX platform onto a new Unity, and so far everybody has been very happy with it because it has been a very seamless transition with very good performance from a VDI perspective."

More Dell Unity XT pros

Cons

"Adding some functions to the product would be beneficial."

"There are some challenges with data encryption and reduction."

"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."

"The software layer has to improve."

"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."

"It feels more suitable for small and medium-sized businesses rather than enterprises."

"I'd like to see the product implement active replication for vehicles such as VMware."

"The UI for this solution needs to be improved."

More Everpure FlashArray X NVMe cons

"Snapshots are not as easy to access as on a NetApp device."

"We had just one small stability problem with power flapping and it did not start up again automatically. We had to access service ports and manually restart the storage processors."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

"It's annoying that if you turn on SMB3 (as opposed to the earlier CIFS protocol), then it is not possible to access a file store using a mixture of SMB and NFS."

"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."

"In the proxy section you can’t choose a user account and password, so it is not allowed at the moment to go out, if customer has such constellation."

"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."

"It only keeps one hour of real-time data without the ability to do deep analysis of each element."

More DDN IntelliFlash cons

"We would like to see more advanced integration capability added to this solution."

"Unity only does compression. It would be nice if there was a deduplication feature as well."

"The solution can use improvement with the patch cluster like the Synchron and Active replication."

"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."

"The EMC VNX Virtual Data Mover (VDM) software needs more improvement."

"The price of Dell EMC Unity XT is higher compared to other solutions."

"Our customers are mostly happy with Unity except for the price. We primarily sell to enterprise companies because small companies cannot afford it."

"We would like to see the concept of Storage Groups brought back to this product line."

More Dell Unity XT cons

Pricing and Cost Advice

"Pure FlashArray X NVMe’s pricing is cheaper than other products."

"The product is expensive."

"Pretty much everything that you need is licensed when you buy the product. Licensing to me is different than the maintenance cost, but they can bleed into one another. We buy the product, and we expect three years of support bundled into what we negotiate on our storage arrays. I would start to see maintenance costs going into the fourth year, but we're not there yet."

"The licensing is on a yearly basis."

"With VMware, we pay $300,000 annually."

"Our licensing fees are $500,000+ USD."

"Given its price, Pure is not the first option."

"Its price could be better. It is not too expensive, but it is the high-end cost. It is kind of a Rolls-Royce. You pay a lot, but you get a lot out of it. So, the price pressure on the way down would be great, but at the end of the day, if you need to do the work, you just pay for it."

More Everpure FlashArray X NVMe pricing and cost advice

"I recommend the full bundle software in order to have all the functionality. It is more expensive to purchase it one by one."

"I think we pay around 100 grand per year for three arrays or four arrays."

"Most licenses for the solution are free but upgrades are available when adding additional software or storage."

"Go with the virtual appliance versus the hardware."

"From an ROI perspective, I'll put it this way: When we've tried to buy other SANs, the Unity ROI makes it impossible to buy them. So usually, the only time we buy another SAN is when the ROI isn't a factor, because Unity can't do the job. From an ROI perspective, it's great because it beats everything else out. We've tried to look at other options but, at the end of the day, when you price it out, the Unity wins."

"In the SQL Server instances in our data warehouse, we immediately saw a great return on investment."

"The price is good for commercial grade storage arrays."

"This product is cheaper than the EMC VNX solution. It is good for small businesses."

"All the licenses are included from day one of your purchase of the product, so you don't have to buy licenses separately. There are no additional costs to be paid for the maintenance of the solution."

"The price of the solution should be less expensive. However, at some point, you need to pay for facility and performance."

Reviews from Real Users

Below are some reviews and helpful feedback written by Dell EMC Unity XT users.

A Systems Engineering Manager at a manufacturing company says, "It is definitely one of the most robust, solid, well-performing products that I have dealt with. It is set it and forget it, which is pretty amazing." He also mentions, “We can do both block and file storage on one unit without purchasing a separate device.”

Peter S., Senior Technical Specialist at a healthcare company, states, “The most valuable feature is reliability. At the end of the day, it just runs. This solution is easy to work with and easy to maintain.”

PeerSpot user Melvin T., Senior Systems Engineer at Prosperity Bank, explains that the solution is “easy to use and we can add LUNs or space without interruption to end-users. We're able to access it from just about anywhere, as long as we have access to a browser. That feature is really neat because sometimes we will go to a different data center or a different site, and if we need to access it to see a LUN or to see any type of storage, we can do that. That's one of the big takeaways with Unity."
