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."IBM FlashSystem has an easy to use GUI, similar to the IBM Storewize family, which make it one of the best flash storage systems in the market."
"The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range."
"This solution is very stable."
"The most valuable feature of the solution is compression."
"IBM FlashSystem is the best solution for storage virtualization."
"The pricing is reasonable."
"The ability to create LUNs and modify them are the most valuable features of this solution."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"VMware vSAN is a global solution, so we can manage all the storage solutions in one place. It's embedded in VCI solutions."
"Being hyperconverged, it simplifies what equipment we have to buy."
"We don't have to order a storage system, we can just use whatever we have on hand and roll it into our virtualization system."
"We have found the solution to be very scalable."
"I like vSAN because they release features incrementally, every year, and you don't have to upgrade your hardware to get those features. If you bought a traditional SAN, you would have to upgrade your hardware constantly, every three years: You would get it, and it is how it is for three years. But on vSAN, you upgrade when you have to, when your hardware gets old or when you need more capacity. It's great, you get new features constantly."
"The most valuable features are ease of deployment, and ease of management. If you compare it to other software-defined storage products, it's much easier. It's a checkbox. It's lot easier to manage."
"Being able to deploy multiple applications with virtual servers is the most valuable for us. The capacity of the system is quite constant so it's got some of the good features."
"Storage virtualization software with a good storage management feature. It's a scalable and stable software."
"There could be some extra features added."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
"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."
"IBM FlashSystems is lagging in optimizing storage technologies."
"Customization features must be improved."
"The solution is not able to replicate data in one-to-many scenario."
"The data reduction pool feature sucks and is not recommended for use with heavy workloads."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"Lacks an integrated backup solution."
"I would like to see more comprehensive lifecycle management. The current path and process for upgrading or updating the firmware, as well as the storage controller software to interact with that firmware, is fairly manual and not very well documented. A little more time and effort spent on the documentation of the lifecycle management for vSan would be really great."
"There could be more features with the automatic backup."
"The solution could be improved by having more filtered and multiple view volumes instead of a single view."
"The platform's cost affects the business. This particular area needs improvement."
"The architecture of vSAN is not good. vSAN works with objects, such as disks, and it causes problems with availability."
"Reporting currently depends on third party applications and that could be improved."
"While I like the replication and compression features, there is a problem with them running too slowly."
IBM FlashSystem is ranked 4th 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, Dell Unity XT, NetApp AFF and Hitachi Virtual Storage Platform, whereas VMware vSAN is most compared with VxRail, Microsoft Storage Spaces Direct, HPE SimpliVity, Red Hat Ceph Storage and Dell PowerFlex.
We monitor all NAS reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
