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."Performance, deduplication, compression, and fast response time for requests from servers and applications."
"It helps us maintain uptime much better than other solutions we've used in the past, and the support is extremely quick and responsive."
"The technical support is very good."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"The ease of management is one of the most valuable features of this solution. I would have also said that it's pretty fast but now our SQL servers are starting to beat it up pretty bad."
"The deduplication and compression meet all of our system requirements."
"One of the lesser sung advantages was when we started running our interface engine on Pure Storage. The ability to process messages and pass them through in our organization skyrocketed purely because of a disk that I owned which we were getting out of Pure Storage."
"It is fast and reliable. It works."
"The most valuable features are the ease of administration and configuration, as well as the speed of deployment."
"The ease of use, the SnapMirror capabilities, the cloning, and the efficiencies are all good features."
"The most valuable feature of this solution is its simplicity. It is easy to use."
"Its consistent stability is one of the things that I like, and the performance is also very good."
"The most valuable feature of NetApp AFF for us is its ability to manage multiple IP spaces for our customers in a shared environment."
"Performance is excellent. In fact, it's so fast that we're not really even taxing it all that much."
"The benefits of being on AFF are the phenomenal speed at which we're able to ingest data and index it, and the IOPS."
"The overall latency in our environment is very low because it's All Flash and we've got 10 Giga dedicated to the storage network"
"The replication feature provides another functionality to protect your data."
"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."
"I really value deduplication and compression to save 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."
"Integration with VMware"
"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 most valuable feature is the auto-tiering, which helps in the speed of data access."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"It took us a year to get it to stabilize and to get the best out of Pure."
"We would like to be able to connect to data tape for backup, specifically to the LTO backups."
"FlashArray's capacity for forecasting should be improved because it needs to be a bit more current. I think it's bundled with the deduplication and other compression factors. We need more user interfaces for forecasting in this software and more interfaces need to be integrated with this array management tool."
"I would like to have support available in Spanish."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"The integration capabilities could be improved."
"The support for NFS protocols right out-of-the-box need improvement. I'm used to other storage vendors who have NFS support right out-of-the-box, and Pure Storage doesn't seem to have anything."
"The primary drawback is the cost, which can be prohibitive for small configurations."
"I would like to see if they could move the virtual storage machines. They have integrated a DR, so you can back to your DR, but there's no automated way to failover and failback. It's all manual. I'd like to see it all automated."
"I think adding more features to make it more cloud enabled will help us with cloud tiering and simplify the whole cloud operations when it's integrating with our on-prem AFF products. That is one area where we would like to see more improvements from NetApp."
"Better stability, not releasing features until they are fully functional, or at least giving us a software train that doesn't add them until they are fully functional and proven."
"On the roadmap, NetApp is improving the solution's storage efficiency, compression algorithms to achieve more space savings, and the management interfaces. We are looking forward to these feature additions in the next release."
"We don't have many issues related to the appliance itself. In terms of the OS, we do get some hiccups here and there."
"The product should be more competitive and come up with additional features. They should keep the client always in mind and as the top priority. This would be the best way to compete with other solutions."
"Implementation needs to be improved."
"Cleaning up false positives on alerts. We get a lot of those."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"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."
"Poor connection to FC."
"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."
"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."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
