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."It is simple to make an update."
"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."
"Stability-wise, this solution is fine."
"High availability and enhanced security; Proven dependability; Data compression with hardware acceleration; Advanced copy services features are all in this product."
"The most valuable features in IBM FlashSystem are IOPS, performance, duplication, and compression."
"The most valuable features are, of course, the virtualization of the storage, the performance, and the compression."
"The initial customer technical support was efficient and effective."
"It's very easy to manage."
"The flexibility is most valuable. Being able to manage things quickly if something goes wrong is also valuable. Very recently, we had one node that went down due to a power problem, but there was really no major impact on the systems running on top of it."
"Storage is expandable with no extra cost."
"We've found the solution to be scalable."
"Everyone uses virtualization to more efficiently utilize hardware resources. That's the main point of vSAN and VMware."
"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 allows us to put our infrastructure in remote locations and still get the same performance we get from our onsite SAN solutions."
"The product's initial setup phase is simple."
"Instead of going for SAN storage, customers can use the scale-up and scale-out features of VMware vSAN."
"We had issues when attempting to do a flash, we hope to resolve it soon."
"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."
"Our model does not support compression or deduplication."
"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 initial setup is complex."
"The pricing needs to be more competitive."
"I would like to see an improvement in the handling of large amounts of rights."
"Sometimes the performance is effective but it gets resolved in the process."
"It needs to be vanilla. There shouldn't be any custom drivers, any custom anything. It should just be, "Hey, you know what? These drivers are going to work for this version, the next version, and the following version after that." That's the difficulty in this. It takes too much upkeep... The main issue is drivers. Every time we move to a new vSAN version, we're having problems finding the correct drivers for the vendor."
"The solution could maybe improve failure protection."
"I would like to see the availability of more template based VMware systems. Combined with the ability to check and measure multiple and converging data segments. Another issue I've seen is that the tool seems to be slow when first starting up."
"VMware vSAN could improve by adding NAS and object storage."
"The platform's cost affects the business. This particular area needs improvement."
"There are certain shortcomings in the stability of the product where improvements are required."
"There's a lot that can be done to segregate. That may be available now in vSAN 7, I suppose, however, the deduplication and compression can be segregated."
"It would be ideal if the solution offered some intelligent monitoring."
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".
