We performed a comparison between NetApp AFF and VNX [EOL] 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."I have seen a huge increase in speed and performance on our databases."
"It's actually very stable"
"The data reduction technology part of the scalability has been impressive, like its ability to host additional workloads, volumes of data, and databases."
"What I like most about this solution, is the speed, resiliency and scalability."
"The most valuable feature of Pure Storage FlashArray is the all-flash storage performance, low latency, and efficiency of their de-duplication technology. Additionally, the ease of use is good compared to other storage systems. The features in data protection, snapshotting, and replication between data centers and sites are superior to other solutions."
"I never have to worry about its performance or if it is the root cause of an issue."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"It's just very easy for general block storage."
"It's pretty scalable. It can scale up to 24 nodes."
"The most valuable features are the speed and performance for our transactional workloads for our databases."
"When we move to all-flash, our response times were reduced to microseconds."
"One of the main features that we love about the system is the ability to create snapshots. NetApp makes a lot of snapshots in a short space of time. Also, the speed of data recovery with NetApp, at the time we need it, is an important feature that we love."
"The speed of data retrieval is the most valuable feature. We mostly use it for our SAP database and we are getting good IO from the hard drive."
"I actually did major projects where we used NetApp storage for some government agencies, and we were able to keep the storage where the government or the customer is able to own the storage while using AWS as their computing. That part was helpful to the customer."
"Previously we had migrated from Dell EMC and we had a lot of difficulties moving data around. Now, if we need to move it to any slower storage, we can move it with just a vault move within the cluster. Even moving data between clusters is extremely simple using SnapMirror. The mobility options for data in All Flash FAS have been awesome."
"AFF has improved my organization because we now have better performance. We can scale up and we can create servers a lot faster now. With the storage that we had, it used to take a lot longer, but now we can provide the business what they need a lot faster."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"One of the best features of the VNX is the ability to combine drives of different types into a virtual Storage Pool. By combining small but fast flash drives, SAS drives, and high-capacity but slower NL-SAS drives, the VNX can intelligently move data to the different tiers of storage based on usage."
"It is very stable, even during multiple power failures."
"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"It is very stable even during multiple power failures."
"Multi-tiering, positively affects the efficiency of the storage space."
"I really value deduplication and compression to save space."
"A year ago they promised that they would be able to read through the database encryption with more metric and they have not delivered on that patch, which is significant because it gives us back so much more storage room. We want to be able to read through the encryption."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"Some services could be inserted directly into the SAN, so Pure Storage could complete with the HyperFlex."
"Pure Storage FlashArray could improve by being more secure."
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"The product should improve its response time. I have also encountered issues with its configuration."
"I would like to see more detailed reporting on the data. However, it would be nice to know what are the exact VMs usage after deduplication and/or what that VMs actual latency and bandwidth is, outside of VMware."
"The technical support is okay, but could be improved."
"It would be nice to have better integration between SRM and VMware, as I've had some issues with that."
"I need faster Fibre Channel over Ethernet. They top out at 10GBs today and I would like that to go to 40 or 100."
"The graphical interface is still heavy and slow. Needs more improvement in this area."
"From my perspective, everything works well. They've already announced that they have some features in their next release that make the existing investment more usable, by adding software features to your existing legacy hardware investment."
"In the current atmosphere, private cloud is improving. NetApp AFF needs to provide flexibility in terms of hardware and capital expense."
"The response to basic problems could be faster. They usually respond fast when there are critical issues, but you always want it right now."
"Its technical support could be better."
"In the past, NetApp designed it so that you have a 70% threshold. You would never fill up past 70% since you need to have that room available. Whereas with Pure, I can fill it up to 110% of what they listed and it's still going at full speed. NetApp can't do that."
"If the VNX had embedded encryption, that would be great."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"It would be very helpful to get an automated report that shows you the size of the checkpoints and get warnings when a checkpoint is reaching either maximum capacity per a file system or hitting the ceiling on the SavVol pool consumption."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"There is an easy replication process between distinct data centers via VPLEX and/or RPA. But I hope in the future that EMC/Dell could replicate this with other types of storage."
