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."
"There are many services that can be directly used which are not available in VMware."
"The documentation was plentiful and very helpful."
"The initial setup isn't too difficult."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The solution is stable."
"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."
"Scalability in vSAN has been really good. It's very easy to add nodes in, to automatically generate the drives and the disk groups. It has been a piece of cake, surprisingly so."
"The migration of servers feature makes server rack maintenance easy."
"IOPS is comparatively best to run VDI solution."
"The feature we have found most valuable is the compatibility of VMware products with VCF and VMware Cloud Foundation."
"The most important thing is the simplicity of the product. It is a well-established product with good stability."
"The solution is easy to use."
"it's easy to scale, it's easy to predict IOP needs, and you can design for low latency using all-flash... Also, for setting up new clusters for VDI quickly, it's nice. You don't have to wait on an order for a storage vendor to ship you a system and help you configure it, you do it all yourself. And the sizing guides are pretty straightforward."
"I have found the solution to be scalable."
"It could use more examples in different languages (API use cases)."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"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."
"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."
"The customer service is good but there is a cost for it. It does not come free."
"They can improve the manageability of the solution to make it more simple. It is not that complicated, but it will be good if they can make it more simple."
"As a software-based product, it requires a lot of system resources."
"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."
"On the DevOps side, if there could be more automation it would be more helpful."
"It can be very expensive."
"Better options would be clustered nodes, or even cloud configuration. There is room for improvement in cloud configuration, we typically do web browsing for management."
"I see room for improvement for vSAN just around general hardware compatibility and expanding that sort of matrix."
