We performed a comparison between IBM FlashSystem and VMware vSAN based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, IBM and others in NAS."The Flash core models offer amazing performance."
"IBM FlashSystem is flexible, quick, and has a solid design."
"The most valuable features of IBM FlashSystem are performance and security."
"It's a mature product. It's like a BMW that evolves consistently."
"The technical support for this solution is good. They used to help us when the motherboard of Power Systems broke. Their response times are really fast."
"IBM FlashSystem is a stable solution."
"The pricing is reasonable."
"The most valuable feature in demand is virtualization and its support storage of virtualization features."
"One of the most valuable features of this solution is that it is stable."
"VMware vSAN is compatible with the legacy hypervisor solutions and most of the features are good."
"VMware vSAN is easy to configure, with basic functionality and the customer can maintain the solution."
"The main advantage is that it's all in the box, with VMware vCenter Server product."
"The feature we have found most valuable is the compatibility of VMware products with VCF and VMware Cloud Foundation."
"The implementation is simple, it was very straightforward. It took us approximately three weeks because it was installed in four locations."
"It is user-friendly, and its performance is good."
"High availability is a valuable aspect of this solution."
"A big area for improvement is that the data reduction pool feature is not recommended for use in a production environment because it has stability and performance issues."
"This solution could be improved by offering greater amounts of storage."
"Additional licenses might be added for the fundamental licenses, such as those for copying and flash copies."
"The product needs to improve their scalability."
"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."
"The storage capacity of this solution could be improved."
"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."
"The solution should improve its pricing and the mechanism in the reduction pool."
"I would rate the stability a seven out of ten."
"As a software-based product, it requires a lot of system resources."
"They should make the software updates easier. We should be able to upgrade it more easily."
"If we have some complicated issues, you have to use the command lines interface. Not everything is possible to be fixed in the GUI. This is a drawback, that some things have to be fixed via command-line interface and should be able to be done in the GUI."
"The monitoring feature in VMware vSAN could be better."
"This product is very expensive."
"I have used the VMware Replication but I can't get it to work properly. The process should be simplified."
"A vSAN cluster must have compression and deduplication to be an all-flash array, but it's not supported with a hybrid array. Deduplication and compression work better with an all-flash array, so I think that VMware should give customers the option to activate and support this feature for hybrid arrays. Other products like Nutanix support this."
IBM FlashSystem products are enterprise computer data storage systems that store data on flash memory chips. Unlike storage systems that use standard solid-state drives, IBM FlashSystem products incorporate custom hardware based on technology from the 2012 acquisition of Texas Memory Systems. This hardware provides performance, reliability, and efficiency benefits versus competitive offerings.
