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 is flexible, quick, and has a solid design."
"One of the valuable features is the performance, it is one of the best in the market."
"When it comes to the interface of the solution we did not encounter any challenges. Additionally, the solution has good documentation."
"IBM's technical support do excellent work."
"The speed of the unit is its best feature. It performs very well."
"The most valuable features are deduplication and compression, which together, enable you to have more space."
"Over the years, it has become increasingly user-friendly."
"Speed (IOPS/second) – It is most vital for applications that need low latency and high speed for transferring the data."
"I have used VMware for 15 years and I never had any problems with stability."
"The most valuable features are productivity and data storage."
"I like the orchestration feature."
"Storage virtualization software with a good storage management feature. It's a scalable and stable software."
"vSAN is scalable for us. If any additional capacity needs to be included, we just add to the host and configure the vSAN cluster."
"Stability-wise, I rate the solution a ten out of ten."
"In my opinion, vSAN is the most natural way to migrate to a fully hyperconverged solution. If a customer needs a more scalable solution with consolidated management, vSAN is excellent."
"By eliminating dependency on that back-end storage, we now depend on everything that's in the VMkernel with vSAN. We eliminate the middleman."
"Our customers have raised concerns about the limitations of the FlashSystem 5200 and 7300, which only offer a 32-gigabyte connection."
"Replication features need improvement. Currently, they are there in the product, but I'm not sure as to how it works exactly."
"The design is a little old-fashioned and could be updated. The rack is very primitive and designed in an older style."
"There could be some extra features added."
"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."
"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."
"This solution needs a management console where we are alerted to issues and can report them, or escalate them through email or another method."
"IBM could do more marketing and improve brand awareness. I had never heard of this product until a colleague told me about it. FlashSystem could add a few features, but it would probably increase the price. For example, Pure Storage offers instant snapshotting and partitioning. That would be nice to have, but I think the cost would go up."
"I would like compression and deduplication to be offered for offloading hardware, instead of doing it with software. That would be nice."
"The integration could be improved. I would like to see integration with other platforms."
"It doesn't seem like it gives the performance that an actual SAN would give for heavy IOPS, read/writes."
"We plan to switch products since the hardware nowadays is a little bit outdated and we need to scale up a bit."
"Perhaps they could provide encryption without having to use an encryption manager."
"It could be cheaper."
"The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that."
"On the DevOps side, if there could be more automation it would be more helpful."
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.
