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."The solution is scalable."
"The most valuable feature of this solution is reliability."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"Technical support has been helpful and responsive."
"The most valuable feature of this solution is its ease of use."
"We're able to get higher-density workloads on the same infrastructure, and we have a smaller physical footprint. The performance is excellent – during our test the bottlenecks are never on the X array, it just keeps picking up the pace to match what you need. The real-time visibility is a differentiator in my opinion."
"It's incredibly easy to use and greatly simplified our ability to both deploy and manage our storage subsystems."
"One of the best features is the support, which is excellent."
"Setup was simple and easy."
"NetApp AFF's flash technology offers great performance. This feature has been my go-to for managing data and ensuring speed and reliability."
"The performance of NetApp AFF allows our developers and researches to run models and their tests within a single workday instead of spreading out across multiple workdays."
"Speed. it's very performance designed. It's designed to have a lot of high speed."
"AFF works well for VMware storage."
"The scale up version of it is the most valuable feature. You can go to 24 nodes, which is very cool."
"It simplifies data management for NAS environments with its ease of management, ease of share creation, and Active IQ feature. These features are good overall. It helps us manage data quickly and sufficiently. Also, compression features, like dedupe, give us a good ratio."
"It has a good interface. Its configuration and flexibility are also good."
"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."
"Integration with VMware"
"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."
"Multi-tiering, positively affects the efficiency of the storage space."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"It is very stable even during multiple power failures."
"The replication feature provides another functionality to protect your data."
"We would like to see more visibility into garbage collection and CPU performance in the GUI."
"The UI for this solution needs to be improved."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"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."
"In terms of what needs improvement, the dashboard and management could be simplified."
"I would like to see replication and DR features in the next release of this solution."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"In terms of what needs improvement, I would like to see more consistency with the UI. It seems to change every few versions. The menus can be in a completely different place."
"After the three-year prepay, the extended warranty is a little expensive."
"I want an interface through ONTAP that look more like what it does for the E-Series with Santricity."
"I would like to see the ability to include more applications from applications to managed storage. If we can have more applications or more interface in more applications, that would be great."
"It would be very useful if we could do the NFS to CIFS file transfer, but it is not supported at this time."
"In terms of improvement, the support could be a little better."
"We have been seeing some challenges around the application layer implementation. We are having some teething problems now with the cooperation between the application layer and backups to things, like SnapCenter. This may be a question of product maturity."
"During the initial setup, you need to know what you are doing."
"Based on our workloads, we see repeatedly in performance reports that the built-in controller (SP) cache of our VNX model is not sufficiently large, resulting in forced cache flushing."
"Poor connection to FC."
"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."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do 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."
"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."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
"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."
