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 documentation was plentiful and very helpful."
"I like its integration with GitLab and its simplicity. OpenStack has a lot of third-party libraries that it uses."
"The initial setup isn't too difficult."
"The solution is stable."
"It created a reusable library with OpenStack features."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"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."
"Easy-to-use, and easy-to-scale product."
"VMware vSAN has greatly reduced refresh spending."
"The solution's unified administration is its most valuable aspect."
"The newer versions of this solution are much more stable and easier to manage."
"Its ease of use is most valuable. It is easy to configure, and there is a unified interface, which makes things slightly easier."
"It is very easy to set up and very easy to use. It is very useful."
"By eliminating dependency on that back-end storage, we now depend on everything that's in the VMkernel with vSAN. We eliminate the middleman."
"I have used VMware for 15 years and I never had any problems with stability."
"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."
"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."
"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."
"We would really like them to look at what Nutanix did for day-one/day-two operations deployment: Bringing in the equipment, getting it deployed, getting it setup, and ease of use of one-click for deploying our 30-node solution. With vSAN we had to go into each one individually and set it up."
"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."
"Lacks an integrated backup solution."
"Its price could be improved. It is too expensive for our clients."
"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."
"The price can be reduced. Small businesses cannot afford this solution."
"Some intelligence can be added to the newest version to provide more flexibility between storage tiers."
"Currently, one of the available features is shareable VMBKs. You can create the VMBK disc and you can make them shareable between the ends. But as soon as you start using this feature, you lose the ability to create snapshots."
