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 speed is the most valuable feature, along with the ease of getting it connected. We were able to get it online in less than a day."
"Running SAP on Pure Storage helps a lot without doing any further tuning to improve application performance. Our internal clients are happy."
"The most valuable feature of the Pure Storage Flash Array is the blazing fast monitoring."
"The solution has probably reduced my power use substantially."
"Having fast storage allows actual servers to perform in high capacity so we don't have slowdowns on our applications."
"The deduplication in the array combined with its snap technologies allows the product to be remotely/manually controlled or scheduled."
"The management features are well organized and they have a very good dashboard."
"We find the ease of usability and setup valuable."
"Its consistent stability is one of the things that I like, and the performance is also very good."
"It has improved performance for our enterprise applications, data analytics, and VMs. These improvements are a result of all-flash, throughput, reliability, compression, etc."
"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 just migrated two petabytes of data storage from IBM over to NetApp All Flash. Some of the performance improvement that we've seen is 100 times I/O and microsecond latency."
"It's very stable. It's always there when we need it. With the Dual Controller, if one drops out, the other one comes right online. We don't use any iSCSI so there is a little bit of a latency break but, over the NFS, we don't notice that switch-on. We can do maintenance in the middle of the day, literally rip a whole controller out of the chassis, and do what we need to do with it."
"It has a good interface. Its configuration and flexibility are also good."
"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."
"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."
"Multi-tiering, positively affects the efficiency of the storage space."
"Good performance for VM environments"
"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."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"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."
"Integration with VMware"
"It is very stable even during multiple power failures."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"As long as they always improve on IOPS speed, that's all we're really looking for. The faster the storage can be the more we can do speed of application and speed of use."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"The integration capabilities could be improved."
"I would like to see more cloud integration."
"Just some nit picky stuff, like allowing servers and volumes to be grouped. Therefore, it would easier to work with them in the GUI."
"As partners, we should have the option to download the software, rather than have to go back through Pure to obtain it."
"I would like to have an easy way to determine the cost per VM so that I can present a solution to our customers."
"The procurement process could be improved. It takes a long time for us to receive stuff. The product is good. It's not the product, it's just that it takes forever to get it. It's not our reseller's problem; it's usually held up at NetApp."
"I would like for them to develop the ability to detach the fabric pool. Once you've added it to an aggregate it's there for life and it would be nice to disconnect it if we ever had to."
"It has not reduced our data center costs. NetApp charges a pretty penny for their stuff."
"ZAPI is kind of difficult to use. You know, it's SOAP-like, it's not really SOAP. I would like to see it more of a REST-based JSON, instead of XML."
"As for AFF itself, I don't have any suggestions of what I would be excited about seeing. I think that adding the support for the rest of APIs to AFF would be super handy. I think it's something that we've been waiting for for a while which would be fantastic."
"It would be better if they just improved the performance of the system."
"Going forward, I would like more performance analytics on it, on the area itself, instead of using some other tool."
"The quality of technical support has dwindled over time and needs to be improved."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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 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."
"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 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."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"If the VNX had embedded encryption, that would be great."
