We performed a comparison between CLARiiON 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)."Service from EMC was extremely good. Whenever a disk had a problem, EMC was right on top of it. In some instances, they called me before I even knew what was going on."
"It is very stable even during multiple power failures."
"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."
"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 replication feature provides another functionality to protect your data."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"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."
"It needs better deduplication. Deduplication was costing too many resources, hence we never used 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."
"The CLI could be better documented, like with VMAX."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"Poor connection to FC."
"If the VNX had embedded encryption, that would be great."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
CLARiiON CX4 series [EOL] doesn't meet the minimum requirements to be ranked in Modular SAN (Storage Area Network) while VNX [EOL] doesn't meet the minimum requirements to be ranked in Modular SAN (Storage Area Network).
