We performed a comparison between IBM FlashSystem 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 stable; no worries about how much it can handle."
"The predictive performance analytics are good."
"It helps to simplify storage because it has an easy front-end to access everything."
"Our storage phones home. It is smart and intelligent in that aspect, which has been huge for us. We don't have to be storage administrators."
"We've had to use tech support on a number of occasions. They did everything remotely and talked us all the way through. They fixed the issue within 30 minutes. Every single time we contact them, they're perfect. I would give their technical support a ten out of ten."
"We've been using FlashArray's snapshot for backups. Their replication across sites and response time are also excellent."
"My rating of Pure Storage is a ten out of ten because of the price for performance and footprint - the overall value."
"This solution is very scalable."
"The speed of the unit is its best feature. It performs very well."
"The valuable features are high availability, compression, and a failover mechanism. It's a very highly available storage solution."
"Flash disk with Easy Tier option"
"The most valuable features are flexibility and performance."
"The performance is very good and we use this product to enhance our core system."
"Data deduplication is one of the most valuable features of this solution."
"The most crucial feature of IBM FlashSystem is compression."
"The most valuable feature is that is supports a high IOPS rate."
"Integration with VMware"
"It is very stable even during multiple power failures."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"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."
"I really value deduplication and compression to save space."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"The replication feature provides another functionality to protect your data."
"We've had it in place for about a year and a half and have had zero complaints, other than that box-to-box replication is not encrypted."
"I like what they're doing, but some of my customers complain that they do not have all the bells and whistles and knobs to fine-tune workloads that some of the competitors have. In my opinion, that's good. All customers don't have dedicated storage gurus, and they can get themselves into trouble if they fine-tune too many of those high-performance knobs, but they do get knocked down. Pure Storage takes a hit in the minds and opinions of some of the customers because they cannot customize things as much as compared to a legacy storage provider's appliance such as NetApp, Dell EMC, or even HPE. I personally think 95% of my customers are better off letting the system fine-tune itself. That was something that you needed to do 12 or 15 years ago, but now with all-flash, the technology can handle what it needs to handle. Customers just end up shooting themselves in the foot if they are tweaking too many default settings."
"There's always an opportunity for new feature functionality."
"It needs to improve its price."
"I would like to have support available in Spanish."
"Part of our company works on Dell EMC because Pure Storage did not have synchronous applications when we were purchasing our products."
"Historical analytics would be useful. At the moment, they don't have any type of application built for historical analytics."
"Pure Storage support could be a little better."
"The only issue my team faced was transferring the data from the old system to IBM FlashSystem, which is an area for improvement in the solution."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"Customization features must be improved."
"The technical support in my region is satisfactory but it could improve. Support is very important for customers and downtime is very critical for us. We would like onsite or complete technical support which can help us to minimize our downtime or if problems occur."
"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."
"The marketing could be improved."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"Their technical support needs improvement in terms of reachability for the clients and response times. They should be more responsive and have more online platforms for support. They should make more technical information available online. There could be some kind of documentation community."
"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."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"EMC VNX needs to support bigger SSD and the Next Generation EMC Unity does this."
"If the VNX had embedded encryption, that would be great."
"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."
"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."
