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 ease of use. That's what our customers love. They say it's very easy, they don't need special training, they don't need to call us or any other company or integrator to help them do their job. That's the main reason they purchase Pure."
"The speed of the Pure FlashArray is very, very fast and nothing in the market can compare to it."
"The performance is very good."
"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"Pure Storage technology allowed us to automate tasks, reducing something which started as a 12-hour turnaround down to about 15 minutes."
"We're getting good performance, and the compression ratio is also very good in Pure Storage FlashArray."
"The tool has reduced our power consumption."
"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."
"The business copy solution has become faster using SnapMirror."
"The cloning and snapshot features are the most valuable. With snapshot backup, we can clone a big database in minutes. We take a lot of snapshots for clients in different environments."
"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."
"It's pretty scalable. It can scale up to 24 nodes."
"There are two compression technologies available within it, and they are valuable because they allow for significantly higher data storage capacity and the retention of a larger number of snapshots on the system."
"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."
"Technical support is good."
"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."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"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."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"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."
"I really value deduplication and compression to save space."
"They could improve the price."
"I'd like to see a move towards individual VMs for what the performance of each VM is in a VD infrastructure. I can see the overall volume, but I would love to see things in a more granular level on the VM side."
"I would like to get a weekly report of how our storage has been used, and if there is any storage sitting there not being used."
"We would like to see better troubleshooting aspects. It helps us if we can find out where the problem is. Right now, it's difficult. Sometimes it's difficult to pinpoint the issue. If they had more visibility and more troubleshooting feature built into the tool that would really help."
"If they could make it cheaper, that would be something."
"Pure Storage FlashArray could improve the recent file storage capabilities because it is lacking a lot of features."
"They are doing some stuff with containers and an object search. These could be improved, because containers is one of the main topics that we are talking with our customers about."
"Beyond a certain amount of petabytes, you have to have a separate system. Basically, it's not infinitely scalable."
"It's a little behind on security. It's starting to get into multi-factor authentication, they just started to introduce it but not for all products."
"The Bezels need improvement."
"Customer service is one area of the product line where I would love to see improvement. I have had several vendor experiences with NetApp where I faced challenges in the initial call trying to navigate the requirements of the service level expectation. Their response could be better improved. However, the final result is great. It is just the initial support level where improvement would help to effectively solve problems."
"One of the features that I am looking for, which is already in the works, is to be able to take my code and automatically move it to the cloud."
"Stability could be improved."
"We don't have many issues related to the appliance itself. In terms of the OS, we do get some hiccups here and there."
"I would like there to be a way to break out the 40 gig ports on them. We have a lot of 10 gigs in our environment. It is a big challenge breaking out the 40 gig coming out of the filer. It would be nice to have good old 10 gig ports again, or a card that has just 10 gig ports on it."
"I really don't have anything to ask for in this regard, because we're not really pushing the envelope on any of our use cases. NetApp is really staying out ahead of all of our needs. I believe that there were firmware issues. I think it was just a mismatch of things that were going on. It could have possibly been something in the deployment process that wasn't done exactly right."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"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."
"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 CLI could be better documented, like with VMAX."
"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."
