We performed a comparison between Dell PowerFlex and Rubrik based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, VMware, Nutanix and others in HCI."The ability to run a two-node cluster without a dedicated witness has made this an excellent product for small deployments, which is right on target for our needs in regional offices."
"StarWind Virtual SAN (vSAN) offers a significant breadth of features."
"The fact that I can now count on a true failover solution is what is most appealing."
"Integration with virtualization platforms helped us to resolve many issues we were facing while using the physical storage."
"Virtualizing data infrastructure with StarWind Virtual SAN improves efficiency and reduces operational costs."
"The ability to run the software virtually on every virtualization platform and the ability to eliminate all storage vendor locking are the most valuable features."
"This was a great implementation for a small to mid-size business."
"The best part is the easy way it operates with a very clear GUI without any unnecessary items."
"The most valuable feature of this solution is integration."
"The support team responds quickly."
"The support is highly responsive."
"The solution is quite stable."
"The most valuable feature is high availability."
"The solution was connected to alternate storage. It provides great scalability and reliability."
"We've had no issues with scaling the solution."
"The catalog of APIs for automation has been most valuable, although they are quite limited."
"Rubrik is an easy and automatic solution that needs no manual intervention."
"The management and ease of installation are the most valuable features."
"Not having to specify a time to run a backup with a fixed schedule is something that's really beneficial. In the past we had to schedule and try to manually stagger things over the window, to back up everything. Because Rubrik is SLA-based, you say, "Well, I need it to fit in this window here," and it just backs it up when it's most convenient for the Brik and for the third-party system. It looks at the CPU usage and says, "Okay, it's not as busy now. I know I've got time to take the backup." That's a real advantage."
"The most valuable feature is the Instant Recovery, where we can restore a VM or SQL database or any server or application, and have it up and running on their appliance within a few seconds."
"Rubrik is highly scalable and is easy to do."
"In terms of usage, Rubrik has allowed us to retrieve data 80 to 90 percent faster than our previous technology."
"Drives the back-end through a powerful, well-documented API."
"Rubrik's immutability feature ensures the security of our backups by preventing unauthorized alterations. The most effective feature for simplifying our data backup processes is the ability to perform on-demand or scheduled backups and restores, which greatly enhances manageability. The security and compliance features have had a positive impact on our data management practices. We utilize Rubrik not only for virtual machine backups but also for backing up approximately twenty terabytes of unstructured data, including file shares and documents. This allows users to easily restore deleted documents using the Soft Delete feature, depending on the backup frequency."
"The cluster configuration is time-consuming and tedious."
"The number of different ways you can set it up can make it a little daunting."
"I see no need for major improvements but there could be some improvements in the form of notifications and the simplifying of maintenance mode."
"If there are domain controllers inside the cluster, there needs to be some sort of logic allowing them to boot independently so all the rest of the domain clients can gain the authority they need to come online."
"There is no Italian-language version of the software available."
"The Command Center, a free guest VM for management and monitoring, leaves something to be desired. It could have more accurate real-time information and better reporting visuals, which seem to be an afterthought."
"The documentation can be better for the free tier."
"Geolocation could be better, for example, for site mirroring for DR purposes."
"The support of containers needs to be improved. At present, it is limited to VMware. There needs to be direct communication with the hardware rather than through a hypervisor."
"They should provide continuous support for data migration."
"The solution needs to offer more documentation and educational materials."
"The solution must be more flexible."
"We're also running Hyper-V virtual machines. But we recently discovered that migration of the Hyper-V virtual machines is a bit challenging. Maybe if Dell EMC can come out with a tool that will make it very easy for us to migrate the Microsoft Hyper-V machine, that may be an improvement."
"Licensing restrictions can be frustrating."
"The storage capability must be improved."
"It would be great to get earlier access to beta builds because we have to develop providers on our own. The APIs and enablers for custom automation could also be improved."
"The dashboard and user interface could be improved to make them more user-friendly."
"The deployment and configuration of the backup service is something that could be streamlined a little bit, particularly when you're trying to do a SQL workload. You have to install a backup service on the server. You only have to do it once and then you're done, but you have to do that on every server that you want to protect."
"Rubrik can only leverage cloud storage for archiving and has no cloud failover."
"There are some corner cases where the Rubrik Connector (Agent) still doesn't work for our clients."
"The Polaris piece could use improvement. When you get a report and you have events that are suspicious, you cannot drill down and find out why it's suspicious. You only know it's suspicious, but you don't know the root cause. Other than that, everything works well."
"Lacks availability in a NFR format of virtual appliances to test them in public cloud environment."
"The solution's reporting feature could be better."
"The interface is still slightly clunky and has room for improvement. They do work with us whenever we mention anything that needs to be done or anything that we want. We find that bringing up the management interface is a little slow and not as intuitive as we would like, but it's been getting better as it evolves."
