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."Simplicity and reliability are the most valuable feature of Pure Storage FlashArray."
"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."
"It is fast and reliable. It works."
"The most valuable feature is how it simplifies the management of the SAN."
"The initial setup was very straightforward and very quick. It was up and running in our data center within 24 hours of receiving it."
"It reduces space and the polar consumption. It also accelerates the application."
"I like its speed. It has all the features that I need."
"Data deduplication features make it easier to manage storage and forecast growth."
"Scalability is excellent. If we need more space, it's a no downtime solution. It's harder to get the funding than it is to get the solution itself."
"The most valuable features are the speed and performance for our transactional workloads for our databases."
"It is easy to manage data through the GUI by using Active IQ and the unified manager."
"I would say the consistency with the ONTAP versions and the speed and performance from the flash."
"We have never had a failure. We can upgrade as we move along with zero downtime."
"The most valuable features are high performance and encryption. It also provides aggregate level dedupe."
"Speed, reliability, ease of use are the most valuable features."
"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."
"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."
"I really value deduplication and compression to save space."
"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."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"Good performance for VM environments"
"Integration with VMware"
"The replication feature provides another functionality to protect your data."
"The price of the solution can improve."
"Pure Storage FlashArray could improve in the area of cryptographic information in the consoles. The user-friendliness could improve. The Pure Storage FlashArray team should come and log into the system with their maintenance credentials and then pull out the information as evidence of cryptography."
"We would like to integrate it more with our backup solutions."
"In terms of the future, I have been excited by some of the copy data management stuff that they're talking about building into the environment. There are feature sets where I've done a lot of automation work. So, I am always looking forward to extensions of their API. They're also talking about a phone home centralized analytics database being used as a centralized management console with a list of new cloud features, but this doesn't seem finalized."
"There's always an opportunity for new feature functionality."
"The integration capabilities could be improved."
"The internal garbage collection process has been fixed recently in some OS updates so it is more efficient but that could be just a little better."
"We do have an issue with the vCenter integration. Pure Storage says it has a lot of free space, but vCenter says its completely full. This is because their dedupes are saved as space, but Vcenter still detects the disk as completely full. So, we do have an issue with that."
"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."
"Offering the ability to actively write data on a single volume spanning multiple clusters is significant."
"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."
"It would be helpful if the compatibility matrix was a bit better."
"The support documentation has room for improvement."
"We have had trouble with restoring applications, and if there is more support for application-aware backups then that would be great."
"When you look at the competitors, they have some features available, for example on the deduplication side."
"We have had customers asking about S3 support for a while now. I heard that is coming in one of the next versions. So, I would like to see S3 targeted support on the FAS system."
"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."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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."
"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 CLI could be better documented, like with VMAX."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
