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."I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"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."
"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"The solution is stable."
"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."
"The solution's unified administration is its most valuable aspect."
"It is easy to find information out there, not only from searching the web, but even the times I have engaged VMware support."
"The most valuable features of VMware vSAN are that it receives updates frequently, has good compression, optimized storage, and they provide webinars on what is new. Additionally, the integration with third-party products is good and it is easy to manage."
"Stability-wise, I rate the solution a ten out of ten."
"The scalability has been quite good."
"The product’s most valuable features are performance and expandability."
"One of the valuable features of vSAN is it has a universal type of technology that allows you to deploy it on any server or hardware. Competitors, such as Nutanix, provides the AOS and can be deployed only on certified hardware. For vSAN, it does not require any kind of certified hardware."
"Everyone uses virtualization to more efficiently utilize hardware resources. That's the main point of vSAN and VMware."
"It could use more examples in different languages (API use cases)."
"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."
"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 seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"The line migration is a problem."
"We do see weird things crop up every now and again. It will say that a drive gets kicked off even though it's fine, and we have to re-add it."
"Pricing is something of a concern."
"It would be much improved if we could somehow integrate a better backup with it. Right now, we're using Veeam and it's okay, but I would like more of a VDP vSAN solution. That would be excellent. The VDP, at least the last time we looked at, it was just not quite there."
"This product is very expensive."
"The integration could be improved. I would like to see integration with other platforms."
"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."
"It is a memory intensive app."
"It should be easier to use."
