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, Nasuni and others in NAS."The most crucial feature of IBM FlashSystem is compression."
"The most valuable feature is reliability."
"This solution is really user friendly. It also offers good performance and is highly reliable."
"The valuable features for us are the extra add-ons, such as the FIM provisioning, the compression, the disaster recovery capabilities, and the storage pooling functions."
"The speed and the ease of installation are the most valuable features."
"They have a virtualization feature and, even if you do not want to buy that feature, you can have it as a trial for two to three months. If you have another brand of storage from another company, you can use this tool to transfer all your data from the old system to the new Storwize system, which really shortens the migration time."
"It is simple to make an update."
"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."
"It has a single pane of glass for management and operational control, which is the most valuable feature. The integrated storage is also valuable."
"It is more stable now than it was before. It's not like it was in the first year. Now it is stable, and we trust it more."
"It completely removes the need for a storage network and for a storage administrator and all of that infrastructure and the costs that are involved with them."
"Technical support is good."
"It is simple to manage, very easy to implement and troubleshoot in case of any failures."
"The simplicity, as well as the integration with virtualization."
"While we haven't made major changes to our disaster recovery and business continuity processes yet, moving towards stretch vSAN across sites will simplify and expedite our DR processes in the future."
"I like the scalability and the fact that it reduces your total cost for storage over several years."
"The GUI for monitoring performance metrics could provide better visibility. For example, it doesn't let me segregate the IOPS per volume."
"I would like to see bigger modules."
"It could be easier to implement."
"One area for improvement is in the GUI, where host clusters are not properly dealt with. With Hypervisor host clusters, all hosts must see the same volumes in the same order. Using the concept of a “host-group” has been around (even with IBM) for many years, so why not with the V7000?"
"IBM FlashSystems is lagging in optimizing storage technologies."
"Enterprise data storage needs improvement. They should create a feature for data and file storage."
"Include an option to upload the support package to the IBM ECuRep when opening an IBM PMR."
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"The interface is a little complicated, it could be simplified with more graphical gadgets. We have many servers, and the built-in functions, such as rate configuration, are a bit complex."
"There is room for improvement in vSAN's ability to debug. When it's not working well, debugging becomes quite challenging. Identifying issues when it's lagging or not functioning properly can be difficult."
"he list of hardware supported should be increased in the future."
"I would rate the stability a seven out of ten."
"It would be ideal if clients didn't need to monitor the solution on a daily basis."
"Some intelligence can be added to the newest version to provide more flexibility between storage tiers."
"Licensing costs are a little too high for smaller sized companies."
IBM FlashSystem is ranked 5th in NAS with 106 reviews while VMware vSAN is ranked 2nd in HCI with 227 reviews. IBM FlashSystem is rated 8.2, while VMware vSAN is rated 8.4. The top reviewer of IBM FlashSystem writes "An easy GUI and simple provisioning but our model does not support compression". On the other hand, the top reviewer of VMware vSAN writes "Very stable, easy to set up, and easy to use". IBM FlashSystem is most compared with Dell PowerStore, Pure Storage FlashArray, Hitachi Virtual Storage Platform, Dell Unity XT and NetApp AFF, whereas VMware vSAN is most compared with VxRail, Microsoft Storage Spaces Direct, HPE SimpliVity, Red Hat Ceph Storage and Dell PowerFlex.
