We performed a comparison between DDN IntelliFlash and VMware vSAN based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Hitachi Vantara and others in NVMe All-Flash Storage Arrays."Their REST API is wonderful, well-documented, and easy to use."
"The solution offers amazing performance."
"We can store more for a cheaper price as opposed to paying for larger devices and larger rack spaces which get outdated sooner and which we'd have to change every two years. It simplifies storage for us."
"It's actually very stable"
"It reduces space and the polar consumption. It also accelerates the application."
"It helps to simplify storage. For most of our customers, when they move to Pure Storage, storage becomes an afterthought."
"We also use VMware integrations developed by Pure, their plugins in our vCenter environment. They help by allowing our non-technical operations teams to deploy new data stores and resize data stores without me having to involve myself all the time to do those simple tasks."
"Provides fast access and is user-friendly."
"It provides a combination of all the protocols that you need, without losing deduplication and compression."
"Data Compression: Up to 80% space reduction in the database"
"It performed great originally, and when it performed great, it was awesome."
"It has reduced our electricity usage by reducing the amount of disks needed for the virtual environment."
"EasyTier/hotcaching: Valuable because it allows greater performance than standard SAS disks"
"It's very fast. We were seeing read latencies of less than one millisecond. It is robust."
"The initial setup is straightforward."
"High performance and ease-of-management are the most valuable features."
"The product's initial setup phase was very straightforward."
"The most valuable feature is the simplification of storage. We no longer need to deal with Fibre Channel and the external storage arrays."
"Storage policies are used to perform operations in the VMs. This feature allows you to create storage policies for VMs to get performance, high availability, I/O policies, etc."
"It is more stable now than it was before. It's not like it was in the first year. Now it is stable, and we trust it more."
"It has a single pane of glass for management and operational control, which is the most valuable feature. The integrated storage is also valuable."
"Technical support is very helpful and very good at resolving issues."
"The most valuable features are its performance, simplicity, and synchronicity with vSphere."
"All the features are working great."
"We would like to integrate it more with our backup solutions."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"Storage. There could be better storage."
"We haven't seen ROI."
"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."
"Larger capacity and more storage ports would be the two things I'd like to see."
"In the next version of this program, I would like to see increased security, higher encryption, and faster throughput."
"They should work on their upgrades, they're not smooth."
"It's somewhat scalable, but maybe not so much as some of the competition."
"It only keeps one hour of real-time data without the ability to do deep analysis of each element."
"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."
"Snapshots are not as easy to access as on a NetApp device."
"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."
"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."
"Technical support is bad. It'd grade them at 30% or 40%. The response time is terrible."
"They need to offer better integration for a virtual platform to enable you to create hyper-converged solution."
"I lose a node in a cluster vSAN, which is also used as a cluster HA. I lose not only the storage part, which is not necessarily serious (depending on the configuration of the vSAN cluster), but on the other hand, I lose also a node of Compute, which can make things complicated quickly."
"Dedupe in non flash drives can be improved."
"The quality of the customer service and support depends on the vSAN case. For example, if I open ten cases, maybe two or three get resolved quickly. But the other cases have a slow response."
"It could be cheaper."
"I see room for improvement with vSAN in particularly in the reporting realm. Now, with vSAN 6.7, they're starting to include vRealize Operations components in the vSphere Client, even if you're not a vRealize Operations customer. So, that's really good. It exposes some really low-level reporting. I would like to see more of that. However, you have to be a vRealize Operations customer to obtain that. I would like to see more include of this included in the vSAN licensing."
"Pricing is something of a concern."
"The usability is pretty good but it could use a little tweaking on the UI, with a clearer definition of exactly what some of the things do."
"It would be much improved if we could somehow integrate a better backup with it. Right now, we're using Veeam and it's okay, but I would like more of a VDP vSAN solution. That would be excellent. The VDP, at least the last time we looked at, it was just not quite there."
