"DataCore has helped provide flexible, highly available, high-performance storage that otherwise would have been outside our price range."
"Active-active is the most valuable aspect for us."
"It is a very stable solution."
"The interface is user-friendly."
"Oracle OLTP benchmark to test how it improves the performance while using flash drive NVMe."
"Mirroring is the most valuable feature because I can provide a high-level of service and optimize the use of obsolete storage."
"The documentation repository is really useful and kept updated."
"The most valuable feature of DataCore SANsymphony SDS is its high availability. This solution also exhibits good performance and has high stability."
"The initial setup isn't too difficult."
"It created a reusable library with OpenStack features."
"The solution is stable."
"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."
"Apart from the main features, I really appreciate OpenStack's microservices architecture and its flexibility for deployment with different tools."
"The documentation was plentiful and very helpful."
"There are many services that can be directly used which are not available in VMware."
"Management could be improved. The management console sometimes reacts very slowly."
"DataCore should integrate its own file server into SANsymphony."
"I'd like to see the company make the renewal of the software cheaper."
"SANsymphony is missing some features that vSAN has. For example, vSAN has a special feature called continuous data protection. It provides the ability to go back in time to a given moment. You can see what was on your disk in the past up to two weeks. That's a great feature because ransomware attacks are increasingly common, and that provides you some kind of protection."
"Unified storage (all block, objects, and files) should be in a single storage pool with unified storage concepts, hence providing the user with whatever they want."
"If you're dealing with big databases or transactional databases, it might not be the best-suited solution. The design of DataCore's solution isn't oriented towards this type of data."
"DataCore needs a more efficient and better way to keep track of metrics and counters so that we can do baseline analysis to measure performance."
"I would like to see SMPA (Shared Multi-Port Array) technology developed with the aim of allowing a configuration identical to other storage arrays."
"The seamless integration between MySQL services and the rabbitMQ database can be revised during the debugging phase."
"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 line migration is a problem."
"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."
"OpenStack's UI, while user-friendly, could be improved to offer a more intuitive experience."
"OpenStack is difficult for the novice in terms of beginning to use cloud tools."
