We performed a comparison between Dell XtremIO and VMware vSAN based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Pure Storage and others in All-Flash Storage."The scalability options are very nice because you can scale it much better and faster. The scalability was there in the previous environment also, but this is far better than what we had before. It basically helps the user in case they are looking for more storage. We can scale it much faster."
"It does efficient work of storing data while still delivering the performance that you would normally expect from a higher priced solution."
"We like the speed. It's very low latency. In virtualization, you can mask lots of problems, and even in code you can mask lots of problems, with low latency. It's just pure speed and low latency."
"It simplifies building out the storage."
"We have seen savings in our storage. The speed of deployment has gone from several days to a few minutes. This product has reduced that time into minutes, simplifying storage for us."
"Because of the encryption, we have different storage and the encryption can go over both."
"We have tons of capacity on it."
"The product cheaper compared to other solutions concerning the technology that they are using."
"I like the deduplication and auto-tiering features."
"The guaranteed sub-millisecond response time for a 4K block."
"We've seen great enhancements from the performance point of view. There's good availability, stability, and continuity, but the performance actually has increased by 60 or 70%."
"Linear performance – The XtremIO wasn’t the fastest in all tests against other all flash arrays, but even with a massive workload, the response time and user experience were absolutely predictable with no sharp drop-offs."
"The most valuable features are that it is fast and reliable."
"A valuable feature of XtremIO is that, in terms of administration, it's simple and manageable."
"Xtrem10's features are more simple to implement. The integration and interface are also good."
"The solution's most valuable features are the inline data reduction and deduplication."
"vSAN is scalable for us. If any additional capacity needs to be included, we just add to the host and configure the vSAN cluster."
"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."
"The most valuable features of vSAN are its simplicity to deploy and that we can use commodity disks in our servers without complexity or need for external storage arrays or storage specialists on our teams."
"It is easier to deploy than the traditional SAN."
"It allows us to put our infrastructure in remote locations and still get the same performance we get from our onsite SAN solutions."
"Very good VCG notification feature."
"When we do to do more scaled load testing, we can run more dense workloads and still have the same results across all specific nodes"
"We would like more extended historical data to help with some of the capacity planning. This is something that we are asking for all the time. E.g., what was the historical performance of this particular volume? So, we would like more historicals."
"Having something native in the Pure Storage ecosystem would make it integrated and in one single company, and we wouldn't have to work with multiple organizations."
"I can't see where they can make anything better, unless, of course, they lower their prices even more."
"There are scenarios with very specific functionality around VMware integration particularly to do with the way we'd like to manage LUNs in VMware. The tools are pretty good but there's room for improvement there."
"Had some issues with Purity not being entirely compatible with VMware ESXi."
"It's not so scalable. It's got moderate scaling capabilities right now. The clustering technology needs a bit of work, they need to improve that."
"We would like to integrate it more with our backup solutions."
"When we were doing some tests, we found that there was an I/O freeze when they were switching the controller."
"We've encountered challenges in integrating other products with Dell Xtremio, as it tends to be more vendor-locked. This means we can't easily explore other solutions that might work alongside Dell."
"I would like to see the ease of deployment and built-in Metro clustering."
"XtremIO needs to be lower priced. It also needs better endpoints and scalability."
"Sometimes we don't get an immediate response from the support team. The initial POC also took a lot of resources."
"The GUI could be modified more in terms of how the different components are linked to each other."
"One thing that should be improved is the reporting and monitoring tools. It should use real time monitoring for storage, IOPS, latency, etc."
"Right now, external appliances are needed to replicate XtremIO to XtremIO, or to another EMC system."
"The implementation isn't exactly complex, but the solution should have some enhancements in it to make the process more centralized."
"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."
"What I would like to see, for the really small customers, is the ability to have two nodes."
"One area that could be improved is the management feature."
"As no product is 100% perfect, the price for VMware vSAN could still be improved, though it is good when compared to some of its competitors."
"he list of hardware supported should be increased in the future."
"The only thing that can be improved is the cost."
"The upgrading process could be simplified."
"The main problem we had was hardware compatibility, finding the right hardware that was certified."
