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."It is very easy to install and configure. It has got excellent diagnostics. If you really need to see how the box is performing, the console gives you a lot of information. You can set thresholds as well as alerts based on the thresholds, which is a very powerful functionality. They are very proactive. They know how to monitor and manage the systems. They see a problem, and they are all over it before us. They see the problem before we see it, which is very good."
"The duplication algorithm allows us to get a lot more use out of less storage. We're running a five terabyte array right now and we're running probably about 30 terabytes on it. So the duplication rate is pretty phenomenal, without a cost to performance. It still runs pretty smoothly."
"One of the best features is the support, which is excellent."
"It's helped us because we've changed fundamentally what we talk about. We don't talk about storage and different tiers of storage anymore nor do we talk about servers. We talk now about applications and how applications impact the business and end users."
"Offers excellent features like efficient data reduction, a reliable SafeMode, and a great support model for continuous assistance and updates."
"Pure has signature security technology, which cannot be deleted, even if you are an administrator."
"The solution is scalable."
"FlashArray has some fresh efficiency features. I've never seen a storage solution with a compression rating this high before. It's at least 4-to-1 on Oracle databases. It's the best flash storage for Oracle."
"The solution's most valuable features are the inline data reduction and deduplication."
"It was very easy and straightforward to setup."
"Thin storage allocation"
"The solution's most valuable feature is its high performance."
"Ease of management, aside from the serious performance, is the best feature."
"Deduplication and cloning capability"
"Xtrem10's features are more simple to implement. The integration and interface are also good."
"XtremIO’s capability to run any workload without much in the way of design considerations makes this very easy to use and size."
"It's completely hyper-converged, so it's very convenient."
"Provides good performance as well as integration with deployment tools."
"The implementation is simple, it was very straightforward. It took us approximately three weeks because it was installed in four locations."
"The most important functionality is the ability to extend cluster storage and cluster computing power securely without loss of data."
"The most valuable feature is the ability to continue our business needs and have higher visibility. It has definitely increased our business productivity levels."
"The feature that I have found most valuable is that it is easy to deploy. It is easy to create and delete virtual servers. It is easy to create the load balancing and the clustering."
"VMware vSAN is easy to configure, with basic functionality and the customer can maintain the solution."
"The most valuable features are Erasure Coding, Deduplication and Compression, and the advancement in stretching regarding replication."
"Right now, the box itself is just strictly working as a backend storage system. It would be fantastic if we could access it directly like a NAS device through network access or SIS drives. I think they have an interface, but I am not sure how good it is. If we could address a box directly on the network without having to go through a server, it would be great. The replication schemas could be improved. We are not using replication on the storage level right now. We use a different type of replication. If their replication would be as good as the one that we have, I would probably run the replication schema because it might be faster, but I don't know that for a fact. So, I cannot say that they have good replication. All I can say is that they need to inform us better."
"They could add more support for file storage and different types of storage."
"The UI for this solution needs to be improved."
"We have run into a couple of instances recently where we are running out of space. So we have had to buy some more packs for it and they have deployed fine and it has increased smoothly."
"You cannot tag a LUN with a description, and that should be improved. What I like on the Unity side is that when I expand LUNs or do things, there is an information field on the LUN. This is the Information field that you can tag on your LUNs to let yourself know, "Hey, I've added this much space on this date". Pure lacks that ability. So, you don't have a mechanism that's friendly for tracking your data expansions on the LUN and for adding any additional information. That's a downside for me."
"If the customer only needs 500 terabytes and doesn't care how much data they'll put in the server, IBM is cheaper than Pure."
"It is on the expensive side."
"The tool's portfolio is minimal. It is expensive."
"The physical architecture could use some higher levels of redundancy."
"This solution is geared toward enterprise-level companies. Small and medium-sized businesses would find it extremely expensive."
"In the next release, the solution could have better integration and if we can host assets on the cloud, such as NetApp has the NetApp volumes, which we can host on the cloud directly called NetApp CVO (cloud volume ONTAP). Dell EMC should come up with something purely on the cloud rather than manage services."
"Management and reporting need improvement."
"The management should be improved and the GUI interface could be better and easier."
"I would like hardware capacity additions to be a little more flexible. The upgrade path for the existing XTremIO units requires you to purchase 2 XBricks at a time and they need to be the same capacity as the existing XBricks."
"XtremIO is coming to its end of life."
"In some cases where we don’t need the flexibility of the virtualization layer, we could free up resources on the VPLEX by using the storage replication."
"The solution functions as the marketing says, as long as you follow certain rules."
"They can improve the manageability of the solution to make it more simple. It is not that complicated, but it will be good if they can make it more simple."
"The only thing I can think of at this time is to improve the performance monitoring and performance visibility within the GUI."
"Better options would be clustered nodes, or even cloud configuration. There is room for improvement in cloud configuration, we typically do web browsing for management."
"The stability needs to be improved."
"I would like to see better integration between the cloud and our VMware virtual environment. We only have one virtual environment, which is VMware vSAN. Right now, there is little interoperability with the cloud solution at the moment."
"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."
"I would love to see vSAN integrate Persistent Memory and NVDIMMs. I know they're supposed to be working on an elastic tier so that we don't have the issues with destaging from the cache to the capacity. Those are the things that I'm interested in."
