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."It is fast and reliable. It works."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"We've had different types of storage, and three things of this solution are valuable. The first one is its outstanding performance. The second one is its stability. In the about three years that we've had it, we've had component failures, but we never had a service interruption or any data loss. The third one, which is really critical, is that it is super easy to use in terms of provisioning, storage, and managing the arrays. I'm able to maintain a multi-site environment with a couple of dozen arrays with a single mid-level storage admin."
"The most valuable feature is its speed."
"The most valuable feature is test performance. It helps us store large amounts of data along with providing us faster retrieval of data."
"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 tool has reduced our power consumption."
"The performance and the ever-growing maintenance are the most valuable features of this solution."
"The most valuable feature is speed."
"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 most valuable feature is the support. If we have any issues, we can call into NetApp and their support is really good."
"Storage is very reliable. You don't have to do much maintenance."
"It supports our virtualization, our VMware environment."
"We are a large-scale company, and our growth has been pretty significant over the last five or six years. We like the scale, and the way NetApp grows, so that's why we use it. It's mostly for block storage."
"Replication would be one of the most valuable features."
"It is a stable solution."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"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."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"Good performance for VM environments"
"It is very stable, even during multiple power failures."
"Multi-tiering, positively affects the efficiency of the storage space."
"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."
"It needs to improve its price."
"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."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"They could improve the price."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"What it needs to do is work a little closer with solutions, like VMware, so it understands the particular workloads that are on it. Today, it does not understand the applications which are running against it."
"The only time that we had problems with it was that there was a bug in the VVol implementation but, outside of that, it has been flawless."
"When it comes to the cloud, they might need to improve in terms of making it clear why someone would use a NetApp solution over cloud-made storage."
"The Bezels need improvement."
"NetApp AFF needs to focus more on block storage. It has to focus on high-end, performance-driven applications."
"After the three-year prepay, the extended warranty is a little expensive."
"It would be better if they just improved the performance of the system."
"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."
"We have had issues with CIFS presentations and outages, so if that was removed, we could do seamless upgrades without affecting CIFS presentations. That would be an advantage. That's about the only improvement I can think of."
"Migrating from a public cloud to on-prem or on-prem to a cloud can be a bit complicated. They have their own solution, but it should be easy to use."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"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."
"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."
"If the VNX had embedded encryption, that would be great."
"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."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"Poor connection to FC."
