We performed a comparison between DDN IntelliFlash and Dell XtremIO based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The initial setup is very straightforward. You simply plug it in and turn it on."
"Their technical support is excellent. It's the best out of any of the vendors we work with."
"Has also helped simplify storage for us. The other person we put in there, took about a week to implement. And we had both arrays set up within around four hours with a thirty minute drive time between the two locations."
"It is all-flash. This makes it a lot faster than the rest of what we have, as it is able to drive high I/O loads, which is big for us."
"Because of the encryption, we have different storage and the encryption can go over both."
"Pure Storage is extremely reliable — it's never failed."
"The amount of data that I have moved to it from legacy storage has enabled us to retire units that are three or four times the physical size."
"For us, the most valuable feature is the compression and deduplication. Being able to deploy a three to one ratio for storage is absolutely critical in today's world with the growing need for storage and the growing need for more space."
"It performed great originally, and when it performed great, it was awesome."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"The initial setup is straightforward."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"Data Compression: Up to 80% space reduction in the database"
"High performance and ease-of-management are the most valuable features."
"Snapshots are valuable because of their seamless nature, as well as the minimal space each snapshot takes."
"The solution's most valuable feature is its high performance."
"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."
"Very good IOPS performance"
"The most valuable features are that it is fast and reliable."
"It was very easy and straightforward to setup."
"I like the deduplication and auto-tiering features."
"The program is very stable."
"The price could be better."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"I had to contact customer support when a drive failed as I was doing a couple of OS upgrades."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"The price of this solution could be improved."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"There's always an opportunity for new feature functionality."
"It's somewhat scalable, but maybe not so much as some of the competition."
"Performance is horrible now. Our original intent was to buy new storage in about two years. But since it became a critical urgency for us, we decided to purchase a new one in two or three months."
"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."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"Ease of use is key in the converged and hyper-converged world that requires administrators to have both hypervisor and storage skills."
"In some cases where we don’t need the flexibility of the virtualization layer, we could free up resources on the VPLEX by using the storage replication."
"The GUI could be modified more in terms of how the different components are linked to each other."
"I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks."
"I am not too impressed with XtremeIO because we had a major failure."
"Management and reporting need improvement."
"The implementation isn't exactly complex, but the solution should have some enhancements in it to make the process more centralized."
"Management: At the time, there was no snapshot scheduler, so I had to write XSnapCourier to address it. The sad thing is that even after the newest release, which includes a native scheduler, most customers using XSnapCourier chose to stick with it due to a more feature-rich experience."
