We performed a comparison between DDN IntelliFlash and Dell SC Series 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 most valuable feature of Pure Storage FlashArray is the complete set of functions it provides."
"It is an easy to use product for all of my team members."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"It comes with a large number of features out-of-the-box, which makes it easy for us to see problems and manage capacity."
"Pure Storage is extremely reliable — it's never failed."
"They are quite responsive and our local team was pretty good."
"The most valuable feature is its speed."
"I use all the features of this solution and I find them to be easy to use and functional, such as the compression and capacity to expand."
"The initial setup is straightforward."
"High performance and ease-of-management are the most valuable features."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"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."
"Data Compression: Up to 80% space reduction in the database"
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It performed great originally, and when it performed great, it was awesome."
"A valuable feature is the performance of the auto-tiering. It will move hot data up to your fastest Tier 1 or move your slow data down. Data progression is what it's called. With the auto-tiering you can have multiple tiers, you can have your Tier 1 be either spinning or flash, all the way down to 7.2K. It will change the RAID on the fly so your writes come in at RAID 10. After they sit for a while, they get converted to RAID 5, then they'll cool off and move down the tiers. Your performance is kept going, while the cold data is moved to your slow, non-performance tiers."
"With auto-tiering, it's easier to understand than most arrays, knowing that all of your writes go to the tier that you specify, with easy-to-create storage profiles."
"It's very scalable, especially with federation. If you outgrow the number of spindles that a unit can support, depending on the model, you can go into federation."
"It is fast and performs well."
"I find this version to be more budget-friendly compared to products from other vendors. This aspect greatly benefits my customers. It's highly advantageous due to its affordability. The operational aspect is also noteworthy. Additionally, its availability and performance are commendable. The speaker are also equally powerful."
"The solution is stable."
"With federation, you can have multiple systems across sites. You can treat them as one, and with a live migration, volumes don't go down. You can move them from site to site, doing maintenance, and keep your environment up."
"Most valuable features have been the system customization with it, the performance you receive, and their CoPilot Support (or Dell EMC Storage Support)."
"I would like some performance analytics which go deeper than today. It should be specific to some hosts and applications. This would be good."
"I think replication is one area that still needs improvement. Earlier, Pure Storage FlashArray only had IP-based replication. There was no API-based replication, but they have enhanced the feature now. However, they need to work on API replication for C-type of arrays."
"There was some complexity in the initial setup."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"In the next release of the solution I would like to see Vormetric native block encryption."
"They could improve the price."
"The backend of this solution utilizes an Active/Passive architecture, rather than an Active/Active architecture, which is a disadvantage, when compared to some of its competitors. Its storage capacity should be expanded in the next release."
"Pricing could be better in comparison to other solutions."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"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."
"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."
"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."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"It's somewhat scalable, but maybe not so much as some of the competition."
"Snapshots are not as easy to access as on a NetApp device."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"There's always room for improvement in the operating code."
"The lower model, the 3000, should have duplication. It doesn't right now. It's only from 5000 that this is offered, but it depends on the performance. It could be they don't offer it on lower models because the duplication is too much of a burden to the performance."
"We have seen some degraded throughput with mixed workloads. We have been working with Dell EMC to correct some of these latency issues."
"The configuration could be easier in Dell EMC SC Series."
"The connection should be better integrated with the network to offer a better view of the system."
"The lack of reporting would be the main issue."
"Snapshots in VMware. You can’t do snapshots since the storage itself does that. Therefore, some apps (Veeam, for example) don’t work well with this kind of tiering storage."
"Licensing, especially on the storage line, could use some simplification. It's not terrible, but, for example, with the Isilon series, they've gone to completely a la carte. A la carte is very difficult to traverse, as to what you need. It would be more beneficial, at least from my point of view as a customer, if they did it more like car companies do, where there are package lines"
