We performed a comparison between Dell XtremIO and VNX [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."It's actually very stable"
"Provides fast access and is user-friendly."
"It helps simplify storage. When you're running Pure all-flash, you don't have to do a lot of the old Oracle best practices. You don't have to worry about putting log files on a different disk channel than the data files, and those types of issues... That has made it vastly easier to do large volumes, rapid provisioning in databases, without taking a performance hit."
"It has good stability for our company."
"It is always out of the box, and ready to use."
"Data reduction and compression. Sub millisecond latency."
"The top-tier support and reliable storage are the most valuable features of this solution."
"Its array houses our entire production environment."
"The guaranteed sub-millisecond response time for a 4K block."
"Thin storage allocation"
"The solution's most valuable features are the inline data reduction and deduplication."
"It was very easy and straightforward to setup."
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"The solution's most valuable feature is its high performance."
"Deduplication and cloning capability"
"The most valuable features are that it is fast and reliable."
"It is very stable even during multiple power failures."
"It is very stable, even during multiple power failures."
"Integration with VMware"
"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 replication feature provides another functionality to protect your data."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"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."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"The connectivity needs improvement. You do not have the possibility to have a file and block connectivity at the same time on the same machine. It has limited ability to do so."
"The setup needs to be improved the most. They can do a little more with the user interface, but the setup is what I would like to see made a bit easier."
"Pure Storage FlashArray could improve some aspects. There are certain features that are good and there are some features that I see some issues with at the technical level. Those issues are related to replication. They need to resolve those issues, which I have already highlighted to the Pure team. Additionally, there are some issues in the active cluster that could improve."
"It would be good to have metrics of the box's performance so we can see what it delivers, but currently, I can't see what it's actually doing."
"The time-to-market could be better at times, but I think that's true for all vendors of hardware."
"The way Pure Storage does the controller storage warranty or replacement has been an issue for some people who just replace the controllers every couple of years, and that's where some of the confusion with pricing and support has come in. They should be clear on the way the controller replacements happen, as it is important to know whether or not you can get a good return on them, because it can be a little confusing."
"In the next release of the solution I would like to see Vormetric native block encryption."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"The solution needs to be simplified. When you integrate your storage with other systems, could use a little bit of automation."
"Scalability is something that can be improved because there is an issue when it comes to mixing versions."
"I would like to see more scalability."
"The GUI could be modified more in terms of how the different components are linked to each other."
"I am not too impressed with XtremeIO because we had a major failure."
"Management and reporting need improvement."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
"The physical architecture could use some higher levels of redundancy."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"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 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."
"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."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"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."
