We performed a comparison between VMware vSAN and VNX [EOL] based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, Nutanix, VMware and others in HCI."We have experienced multiple hardware failures at one site and the fault-tolerant volume worked exactly as expected with zero downtime."
"StarWind Virtual SAN is a very mature software that supersedes its capabilities with my use cases."
"In our case, the cost and high availability are the two most important factors which we were looking for in a solution."
"Starwind support is excellent. They are very fast and have very good knowledge of Starwind and Hyper-V Cluster software."
"I've had to open a few support cases over the years due to administrator errors, and the support received was top-notch."
"The access to our data is quicker and cheaper than it used to be in a traditional storage system."
"The ability for us to manage all of our nodes from the same console makes systems administration very easy."
"I've been really impressed with it so far. I think it's pretty great, actually. It does exactly what we need it to do, and it does it well, so I would recommend it. Plus, the support has been very good."
"It is simple to manage, very easy to implement and troubleshoot in case of any failures."
"Very easy to implement in any existing environment."
"Stability-wise, I rate the solution a ten out of ten."
"IOPS is comparatively best to run VDI solution."
"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."
"VMware vSAN's most valuable features are the capability to consolidate standalone physical infrastructure into virtualization and the ease of management."
"All the features are working great."
"Storage virtualization software with a good storage management feature. It's a scalable and stable software."
"The most valuable feature is the tight VMware integration, due to the migration from bare metal to virtualized environments and then on to the cloud."
"FAST (auto-tiering): Doesn't require configuration and is managed by the array itself."
"It is very stable, even during multiple power failures."
"High availability including non-disruptive updates: We cannot afford downtime windows."
"It is very stable even during multiple power failures."
"The most valuable feature is the auto-tiering, which helps in the speed of data access."
"From my point of view, the configuration that I can sell is restricted to the EMC best practices. It is hard to make a mistake in a solution. It means the configuration has good performance and scalability options."
"Good performance for VM environments"
"The documentation is good. However, if compared with competitors, it could be enhanced and made more professional."
"We would like to see the documentation more fully developed."
"I would like to see options for automated notifications of any changes, including, for example, synchronization issues."
"Regular updates to the software are required, and subtle design changes would be welcome."
"Other vendors such as VMware vSAN have a bigger community of users, so it is easier to find more pre-sale or post-sale information from users."
"Updating the software can be a bit tricky."
"I want to suggest that the complexity of the startup and shutdown procedure needs to be reduced."
"Perhaps more reporting features on the utilization, usage, and performance of the configured high-availability images and underlying physical disks would be helpful."
"I would like for the next release to be a bit cheaper."
"I would like to see replication as part of it. I would also like to see direct file access, being able to run SIF shares and NFS and the like. I think that would be critical to continuing the use of it going forward."
"I would rate the stability a seven out of ten."
"One thing in vSAN that I would like to improve is using vSAN as a repository for files or other things. For example, with Horizon, maybe we can save profiles with UEM on there. That would be a good feature that I would like."
"When we talk about improvements for vSAN, there is some way to go from a at least stability perspective. Adding all these new features is nice, but we are now at the level that most of the features you need in production are there."
"The architecture of vSAN is not good. vSAN works with objects, such as disks, and it causes problems with availability."
"It doesn't seem like it gives the performance that an actual SAN would give for heavy IOPS, read/writes."
"The big thing is pricing, and the rest of it is mostly good. From a scalability point of view, scaling the storage from network or compute should be easier. It is again all around the cost, and it would be good if it was easier to scale your storage separately from your compute."
"Intel Xeon processors with under 2 GHz processing speeds could be replaced with more recent ones."
"The scalability is average because the storage has some hardware limitations and, obviously, operating system limitations."
"VNX can improve by offering flexible upgrade options. It's not possible to add a single HDD to a current array and there are fixed rules to make upgrades."
"Poor connection to FC."
"EMC VNX needs to support bigger SSDs. Next generation EMC Unity will do this."
"The administrative console (Navisphere/Unisphere) needs some improvement, especially on their Java-based GUI. The updated version of Java is not compatible."
"The management software used for the VNX is Unicenter. While it is an improvement over Navicenter, used in older EMC SANs, it still feels outdated in comparison to other SAN management software."
"There is no easy way to defrag a RAID group. It would be nice to be able to reduce the size of a storage pool if the storage is not needed anymore."
