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."This solution is very scalable."
"Data deduplication is one feature I found to be the most valuable in the tool...Stability-wise, I rate the solution a ten out of ten."
"The technical support is very good."
"It allows engineers to focus on other things rather than doing the more manual tasks. It automates tasks, so the ease of use is extreme. It simplifies the storage."
"Their support system has insight into errors on our SAN fabric that we can't see. They've brought attention to and raised awareness for us about things that we couldn't see, when we were experiencing problems."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"The most valuable features are extremely low latency, high IOPS with VMware, inline deduplication and compression."
"Access speed and power consumption are most valuable."
"The Active IQ feature is a productive mechanism that automatically collects reports and users' statuses."
"If the AutoSupport is well configured, then you need not to do a monitoring. You will get call and mail when any issue is completed."
"The speed is great. That's probably number one in terms of features we appreciate."
"The most valuable feature is speed."
"NetApp is like a one-point central management. For example, one can put everything on the right version and control the whole environment from one software solution."
"The features that I found most valuable are SnapMirror and SnapVault; these provide DR and backup for data redundancy."
"With the new version, they have the FabricPool which works for me. I can extend the hyperscaler storage."
"I think that the DR applications are the most valuable, including Snapshots and SnapMirror."
"Integration with VMware"
"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 replication feature provides another functionality to protect your data."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"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."
"There are many features which need to be added, particularly on the replication side."
"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."
"In the next release of the solution I would like to see Vormetric native block encryption."
"We haven't seen ROI yet."
"The GUI is simplistic and basic. I feel like it's explanatory, but not enough, it needs a little more to it."
"The price could be better."
"The number of Filesystems is limited, which it is not on the EMC VNX."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"We would like to have NVMe on FabricPool working because it broke our backups. We enabled FabricPool to do the tiering from our AFFs to our Webscale but it sort of broke our Cobalt backups."
"I would like to see better tutorials available, beyond the basics, that cover subjects like MetroCluster and automation."
"The admin tools and the integration with other products and clouds can be improved. It should also be easier to identify and troubleshoot problems in this solution. It takes a long time, and it should be improved."
"The bad part about having scalability is the expense. It is currently extremely expensive, to be able to scale so fast on flash."
"The certification classes are good, but they don't cover enough of the material, and the exams only test on what is covered in class."
"I don't like the newest GUI. It needs more options. Some features have been removed. Oversight is not as good in the new GUI compared to the previous version. Though, it might be something that we just need to get used to."
"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."
"There are no RDMA capabilities in CIFS (SMB) and NFS protocols."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"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."
"Poor connection to FC."
"The CLI could be better documented, like with VMAX."
"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."
"If the VNX had embedded encryption, that would be great."
