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)."As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"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."
"IBM XIV's most valuable features are NVME, especially when it comes to de-duplication, compression, and responsiveness."
"The performance and robustness of the systems are very good."
"Installation is amazingly easy."
"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."
"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."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"Multi-tiering, positively affects the efficiency of the storage space."
"It is very stable even during multiple power failures."
"The implementation of both block and file system storage in a single GUI provides is better situated than most other storages."
"Integration with VMware"
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"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."
"Until the drive is replaced, the pool_resizing is locked."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"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 administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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."
"Poor connection to FC."
"The CLI could be better documented, like with VMAX."
