We performed a comparison between Dell CX4 series [EOL] and VNX [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about NetApp, IBM, Hewlett Packard Enterprise and others in Modular SAN (Storage Area Network)."The most valuable feature is the machine learning. We have been using this solution for a year and a half and we haven't had any problems with it."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"Integration with VMware"
"Multi-tiering, positively affects the efficiency of the storage space."
"The replication feature provides another functionality to protect your data."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"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."
"We recently found a problem with one of our Dell tower servers that we are using. The machines sometimes reboot. We went to the vendor to help resolve it and they're taking a long time. We need better support for it."
"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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"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 While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"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."
"If the VNX had embedded encryption, that would be great."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
