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)."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."
"As it spreads, a chuck of 1MB across the board means using all available spindles on the backend."
"Hands down, this is the easiest storage platform on the market to manage."
"Very easy to produce reporting data (Snaps). Very easy and fast for provisioning devices and Remote mirroring."
"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."
"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."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"Integration with VMware"
"Multi-tiering, positively affects the efficiency of the storage space."
"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."
"Good performance for VM environments"
"Until the drive is replaced, the pool_resizing is locked."
"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."
"I would rather have a web GUI served directly from the unit, and a CLI accessible directly through SSH."
"The change form synchronous mirroring to asynchronous (and vice versa) without reconfiguration from scratch would be helpful."
"IBM XIV's scalability is adequate for our requirements, but because it's modular, you can't scale to larger requirements."
"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."
"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."
"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."
"Poor connection to FC."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"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."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
