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."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."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The documentation was plentiful and very helpful."
"The initial setup isn't too difficult."
"The solution is stable."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"There are many services that can be directly used which are not available in VMware."
"The solution's technical support is good."
"The performance of VMware vSAN is very good."
"It uncoupled the idea of proprietary technology and component capabilities. It is basically a proprietary technology for a cost-effective infrastructure."
"While we haven't made major changes to our disaster recovery and business continuity processes yet, moving towards stretch vSAN across sites will simplify and expedite our DR processes in the future."
"VMware vSAN's most valuable features are the capability to consolidate standalone physical infrastructure into virtualization and the ease of management."
"It allows us to put our infrastructure in remote locations and still get the same performance we get from our onsite SAN solutions."
"Technical support has been fantastic. We always get answers quickly whenever we call."
"The product's initial setup phase is simple."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"The line migration is a problem."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"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."
"It could use more examples in different languages (API use cases)."
"So for the main stability, there have been a couple of issues that I've experienced."
"In a future release, they could add micro-segmentation or security level features integrated into vSAN."
"It is a memory intensive app."
"Because of virtual storage, the system reaches reserve storage for its functions. It also consumes a certain amount of storage, which then results in the creation of a fault tolerance for the system. All of this adds to a lot of capacity being consumed in terms of storage for each drive for vSan. I find this to be one drawback of using vSan."
"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."
"The vSan product uses a software system called Vsphere to monitor the system. It is sometimes difficult to manage the PCs within the systems."
"There is room for improvement in vSAN's ability to debug. When it's not working well, debugging becomes quite challenging. Identifying issues when it's lagging or not functioning properly can be difficult."
"The UI could certainly be better. The inside into what's actually going on with vSAN would be nice to know."
"I have used the VMware Replication but I can't get it to work properly. The process should be simplified."
