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 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 initial setup isn't too difficult."
"The documentation was plentiful and very helpful."
"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."
"It created a reusable library with OpenStack features."
"Very easy to implement in any existing environment."
"All orchestration and monitoring are routed to the cloud."
"The technical support is good. We are always thankful for the technical support from VMware. They are very supportive when we have a technical problem."
"Technical support has been very good. They respond pretty fast, especially if we have a critical issue. Their responses have been great."
"The scalability is very good and the solution is stable and reliable."
"It is simple to manage, very easy to implement and troubleshoot in case of any failures."
"The most valuable feature is that it is software-defined storage. Also, being able to do maintenance on the fly is a real benefit: migrating off, updating, and then moving the guest back on to the nodes."
"Stability-wise, I rate the solution a ten out of ten."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"It could use more examples in different languages (API use cases)."
"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."
"So for the main stability, there have been a couple of issues that I've experienced."
"The line migration is a problem."
"The ability to access SAN environments with fiber channels (or even NVMe) would be a good addition."
"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."
"They can package it in a way that is specific to the hardware infrastructure and the hardware platform. It should stay fairly up to date with the drivers and the manufacturer issues. The problem with uncoupling the proprietary technology and component capabilities is that by uncoupling them, you run into some concerns or challenges over the poor performance model. These concerns really come when you start talking about high performance, high bandwidth, and high availability types of environments. While vSAN is a leader, in a critical view, it is not about being cost-effective. It is more about the immediate impact of money loss to the business in critical applications where we want to maintain a continuous operational 59 model. It is, however, good for QA/QC tasks. I don't necessarily know how it works in regards to VDI or virtual desktop infrastructure."
"Integration could be better."
"VMware vSAN could improve by having better integration with other vendors and the storage is limited, I prefer it to the traditional storage."
"I think it needs to be more cost-effective. I would also say that even though the capacity is good, there is also room for improvement there. Also, they could improve the security of the system."
"Reporting currently depends on third party applications and that could be improved."
"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."
