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 helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."
"Support has been helpful."
"It does efficient work of storing data while still delivering the performance that you would normally expect from a higher priced solution."
"The solution is easy to scale. I'm running two environments right now, so I need to scale. I'm running a part technology. I've got an A-side and a B-side."
"NVMe data storage platform that's easy to set up and easy to use. It's stable, with a lower response time, and quick technical support."
"It is always out of the box, and ready to use."
"Very stable; no worries about how much it can handle."
"This solution has helped my organization by cutting down on provisioning time. I used to have to provision a VM and it would take ten minutes. Now, it takes thirty seconds."
"The biggest benefit of NetApp AFF is the performance."
"The most valuable feature of the solution is data protection and snapshot technology for backup."
"We recently started using the volume encryption feature, which is helpful because there are some federal projects that require data at rest to be encrypted."
"The NVMe flash cache is the most useful feature. It lowers transactional speed even more."
"We have SQL clusters across the United States. It has sped up our IOPS and made it a lot easier for users."
"The performance is outstanding when it's all Flash. That's the biggest bang for the buck that we get."
"Previously we had migrated from Dell EMC and we had a lot of difficulties moving data around. Now, if we need to move it to any slower storage, we can move it with just a vault move within the cluster. Even moving data between clusters is extremely simple using SnapMirror. The mobility options for data in All Flash FAS have been awesome."
"Switching to AFF has improved the performance of a lot of our virtual machines in a VMware environment. The number of support tickets that we receive has fallen to almost zero because of this, so it's been a real help for our virtual server support team."
"It is very stable, even during multiple power failures."
"Multi-tiering, positively affects the efficiency of the storage space."
"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."
"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 replication feature provides another functionality to protect your data."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"Integration with VMware"
"On a couple of occasions, the waiting time for an upgrade has been pretty substantial."
"Its price could be cheaper. It is not the cheapest one out there, but I'm not directly involved in the figures and negotiations."
"Pure Storage will have issues with positioning in the near future since its a relatively new company. For now, customers need a PoC to trust using the solution, as it can't stand on its brand name alone. They need to improve Pure Storage's marketing."
"A three wave application or multi wave application synchronization would be an improvement."
"The credentials on the iSCSI interface are only available to type in with the Chrome browser, and not with the Firefox browser."
"It goes at about 95 percent, so we have had some performance issues. It is hard to clear them."
"From a scalability perspective, it is a very small storage solution, so it's not very expandable."
"In the next release of this solution, we would like to see automated copy data management for SQL Server."
"The user interface should be more user-friendly, and the configuration could be more accessible."
"Stability could be improved."
"We have had trouble with restoring applications, and if there is more support for application-aware backups then that would be great."
"I have experienced slow responses several times, if the ticket has only been opened in portal."
"The support documentation has room for improvement."
"After the three-year prepay, the extended warranty is a little expensive."
"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."
"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."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"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."
"The CLI could be better documented, like with VMAX."
"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."
"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."
"Poor connection to FC."
"If the VNX had embedded encryption, that would be great."
