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."
"There are many services that can be directly used which are not available in VMware."
"The most valuable feature is the customization. With the customization you can really give the customers what they want."
"The solution is stable."
"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."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"Storage policies are used to perform operations in the VMs. This feature allows you to create storage policies for VMs to get performance, high availability, I/O policies, etc."
"I like the scalability and the fact that it reduces your total cost for storage over several years."
"The most valuable features are the encryption, deduplication, compression, and the ability to manage all of your storage within your server rack."
"The most valuable features are secure IOPs and LAN security."
"It is user-friendly, and its performance is good."
"Stretched Cluster is one of the big features that we use across multiple data centers."
"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."
"vSAN that has been most effective in streamlining storage operations. For data recovery alerts, it uses tools like snapshots and vMotion."
"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."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"The line migration is a problem."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"So for the main stability, there have been a couple of issues that I've experienced."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
"One area that could be improved is the management feature."
"I am looking for more of a software-defined storage platform that uses different protocols, such as iSCSI, NFS, and CIS, and maybe also has an object as part of that. They should 100% make it more of a storage-based product where it is not linked just to VMware, and it also has NFS and iSCSI built-in at a scalable level. They should turn it more into a dedicated storage-as-a-service platform instead of just being built into the VMware kernel. Their level one and level two support is not at all good, and it should be improved."
"The product can be improved in a couple of ways. One of those would be that they have a lot of hidden features, that are through the CLI, that would be great to have in the GUI, or just be more open about those features. It's something called RVC. It's a tool in the back end. It's a really great tool, but I had to find it through Reddit. So more information on stuff like that would be great. Also, in the user interface, giving us more features and more reporting that we can do from vSphere itself would be helpful."
"There is a room for improvement on the latest version of compatibility with the VMware product, especially for vSAN and with other vendors on their motherboards and driver configurations."
"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."
"It doesn't seem like it gives the performance that an actual SAN would give for heavy IOPS, read/writes."
"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."
"On the DevOps side, if there could be more automation it would be more helpful."
