We performed a comparison between Rackspace OpenStack and VMware vSAN based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Hewlett Packard Enterprise and others in Converged Infrastructure."The most valuable feature is the customization. With the customization you can really give the customers what they want."
"The solution is stable."
"Administrators are very comfortable with the functionality and services OpenStack offers."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"It created a reusable library with OpenStack features."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"There are many services that can be directly used which are not available in VMware."
"The documentation was plentiful and very helpful."
"I think vSAN's stability is good. It's an underlying solution for both on-prem and in the cloud, especially the VMC on AWS stuff too. VMware has been around for a long time, so it's pretty stable."
"vSAN provides default HA configurations, where if any host goes down, the VM moves around within the host. Even though the disks are local, the VMs moves around with the vSAN disk and vSAN provides a high availability on its own."
"The simplicity, as well as the integration with virtualization."
"The product’s most valuable features are performance and expandability."
"It is very easy to set up and very easy to use. It is very useful."
"The most valuable features for us are the ability to scale out the nodes independently, and the flexibility of the nodes. We can put almost any type of server in there with our connectivity and everything works great."
"The most valuable feature is the fast performance."
"If we decide to expand, vSAN could offer us some flexibility. We are researching ways to set this up from a new data center, which is located somewhere different from the current location right now."
"So for the main stability, there have been a couple of issues that I've experienced."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"It should have a single dashboard for cloud management and on-premises systems"
"It could use more examples in different languages (API use cases)."
"The line migration is a problem."
"VMware has a side-to-side replication feature, which is still more mature than Rackspace OpenStack's which can't be used in a production environment."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"I see room for improvement with vSAN in particularly in the reporting realm. Now, with vSAN 6.7, they're starting to include vRealize Operations components in the vSphere Client, even if you're not a vRealize Operations customer. So, that's really good. It exposes some really low-level reporting. I would like to see more of that. However, you have to be a vRealize Operations customer to obtain that. I would like to see more include of this included in the vSAN licensing."
"Improvements are also needed as per the customer's requirements."
"It would be ideal if the solution offered some intelligent monitoring."
"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."
"I would like to see better integration between the cloud and our VMware virtual environment. We only have one virtual environment, which is VMware vSAN. Right now, there is little interoperability with the cloud solution at the moment."
"The solution could maybe improve failure protection."
"I lose a node in a cluster vSAN, which is also used as a cluster HA. I lose not only the storage part, which is not necessarily serious (depending on the configuration of the vSAN cluster), but on the other hand, I lose also a node of Compute, which can make things complicated quickly."
"In a future release, they could add micro-segmentation or security level features integrated into vSAN."
