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 has good, reliable, fast storage."
"The standout features for us in Pure FlashArray X NVMe are its robust DDoS protection, seamless transparent failover, and failback capabilities ensuring high availability."
"It has benefited my organization because it has reduced time to insights."
"One of the best features is the support, which is excellent."
"The most valuable feature of this solution is its ease of use."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"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."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"We are spending less time putting out fires, so there's a tangible benefit right there."
"We do a lot of financial modeling. We have a large compute cluster that generates a lot of files. It is important for us to get a quick response back for any type of multimillion file accesses across the cluster at one time. So, it's a lot quicker to do that. We found that solid-state performs so much better than than spinning drives, even over multiple clusters."
"The most valuable feature of the solution is data protection and snapshot technology for backup."
"Setting up storage for an application (storage provisioning) is quick and easy. Maybe a quarter of the time is now spent getting the application up and running, or even less."
"The tool's most valuable feature is SVM. I also like the speed and response of the filers."
"The most valuable features are the IO performance that we get, the cluster part, and the increased workload and performance with the SSDs."
"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 most valuable features of the solution are speed, performance, and reliability."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"Good performance for VM environments"
"I really value deduplication and compression to save space."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"The replication feature provides another functionality to protect your data."
"It is very stable even during multiple power failures."
"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."
"The tool's pricing is higher than competitors."
"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."
"The software layer has to improve."
"We would like to see VNC integration or be able to use Pure Storage with VNC."
"Our use cases require more multi-tenant capabilities and additional VLAN interfaces for separating different customers. We currently use it to provide storage, sometimes shared storage, to different customers, but it is less flexible in comparison to a dedicated solution."
"The UI for this solution needs to be improved."
"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."
"We need better data deduplication."
"The upgrade process could be a lot quicker, but it's still good as it is. The failovers and things like that are harder than expected."
"There are no pNFS with VMware VVOLs."
"Stability could be improved."
"We would like to have a feature that automatically moves volumes between aggregates, based on the performance. We normally need to do this manually."
"We would like to have more behavioral reporting."
"I would like to see aggregate level encryption in the next release. This is critical."
"I want an interface through ONTAP that look more like what it does for the E-Series with Santricity."
"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."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"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 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."
"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."
"The CLI could be better documented, like with VMAX."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do 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."
