We performed a comparison between Dell EqualLogic PS series 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)."We were attracted by the flexibility of being able to put in a new shelf whenever we needed to, to expand."
"It is extremely reliable."
"It has contributed to the implementation of virtualization and all its benefits."
"The most valuable feature of Dell EqualLogic PS series auto tiering by using this feature, the customer can get higher performance on a valuable budget."
"Dell EqualLogic PS series is a highly stable solution."
"If you have one datacenter fail, the VMs will start to run inside the other data center."
"Dell's technical support is very good."
"You can always trust it. It is stable."
"Good performance for VM environments"
"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."
"It is very stable even during multiple power failures."
"Integration with VMware"
"The replication feature provides another functionality to protect your data."
"I really value deduplication and compression to save space."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"Dell EqualLogic PS series could improve by providing fiber channel connectivity. Fiber channel connectivity is not supported, which is a requirement of advanced applications, such as SAP HANA. SAP HANA recommends fiber channel connectivity, but the Dell EqualLogic PS series is only an ISCSI data storage."
"The solution is out of date and the new version has a lot of advanced features."
"There is no inline deduplication capability."
"We need more space and we can't get any."
"Individual file recovery would be a nice additional feature."
"Dell EqualLogic PS series could improve the performance because in our hybrid configuration the read speed is faster than the write speed."
"6510 and 6610 have two iSCSI connections in each controller. Why do 6110xxx members have only one, and why do the same members have the possibility of having an active iSCSI interface in the passive controller? It could make a lot of noise with a failover."
"Why is it not possible for both controllers to be simultaneously active (load balancing)?"
"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."
"The CLI could be better documented, like with VMAX."
"If the VNX had embedded encryption, that would be great."
"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."
"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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does 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."
