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 most valuable feature of this solution is reliability."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"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 is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The most valuable feature of this solution is its ease of use."
"The latency is good."
"Over the past 18 years, it has been extremely easy to upgrade to newer products and technology. We can upgrade as we move along. So, we have been able to keep up with the newest technology with zero downtime."
"Most of our business-critical systems are provisioned from the NetApp AFF system. Compared to others, we have a minimal latency. Configuring the DR for high availability or migrating the volumes from one box to another is pretty easy with NetApp AFF."
"We are spending less time putting out fires, so there's a tangible benefit right there."
"The most valuable features are the performance and the storage efficiency, due to the compression and deduplication... The efficiency is very important because we can buy fewer disks for more data."
"We have had issues before on our infrastructure where 20 to 30 percent of the people would come to us pointing the finger at the storage technology or storage back-end. That is now virtually zero."
"Regarding features, SnapMirror is one we depend on right now. It helps us provide snapshots to the customers on request. There are many scenarios in which we might take snapshots in various daily use cases. We trigger the snapshots, which gives us a sense of security because we know we have this technology in place if something happens."
"I like some basic features like Snapshot, FlexClone, and advanced features such as SnapMirror, and SnapVault. They also recently enhanced the market with Cloud Volumes ONTAP. I think that NetApp is a very good product."
"AFF helps us improve performance for our enterprise applications, data analytics and VMs. We have moved our primary data stores for production over to AFF, and a lot of the problems that might happened have gone away."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"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."
"I really value deduplication and compression to save space."
"Good performance for VM environments"
"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."
"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 want to see Pure Storage not only be for fast storage, but I want to see it be for the entire data center."
"They could add more support for file storage and different types of storage."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"I would like to see replication and DR features in the next release of this solution."
"Every time I think of something that needs to improve, they're one step ahead, which I love. The only area I wish to see improve, I believe is coming, is in the FlashBlade product. Blade implementation fell short on a few of the services."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"There is room for improvement in catering to midrange storage needs, especially for customers seeking Enterprise-class features."
"I would like to see an improvement in the high availability of the NFS and CIFS sharing during upgrade and patching; this would help to avoid downtime."
"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."
"The quality of technical support has dwindled over time and needs to be improved."
"The product has size limitations on fax volume. They have increased from 100 to 300, which is still less than other vendors. Or flex groups are not supported."
"When comparing with Pure for example, with Pure you have no maintenance anymore and with NetApp, you still need maintenance."
"There needs to be compatibility with upgraded applications. We don't want the system to be upgraded, but not have backwards compatible to existing applications."
"There is no direct storage attachment available. Most configurations require additional switches for data access."
"Technical support is a little lackluster. Some of the issues that we've had were opening up tickets. They seem to be routed in the wrong direction or it takes one or two days to get a call back for simple tasks."
"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."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"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 administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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."
"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."
"Poor connection to FC."
