We performed a comparison between IBM XIV 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)."Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"Hands down, this is the easiest storage platform on the market to manage."
"The performance and robustness of the systems are very good."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"Installation is amazingly easy."
"I really value deduplication and compression to save 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."
"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."
"It is very stable, even during multiple power failures."
"Multi-tiering, positively affects the efficiency of the storage space."
"Good performance for VM environments"
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"Until the drive is replaced, the pool_resizing is locked."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"This product was not a good fit for our organization as we have a ton of latency sensitive applications and XIV was not able to keep up with IO + latency demand."
"I encountered stability (performance) issues during enclosure or disk rebuild. Also some power supply issues due to malfunctions of circuits. Sometimes "internal" Snap sessions hang and consume pool capacity."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"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."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"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."
"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 administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
