We performed a comparison between Dell Unity XT 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 simplifies the overall management. We don't have to worry about storage anymore."
"The most valuable feature is its speed."
"The most valuable feature of Pure Storage FlashArray is its high stability level."
"FlashArray has many valuable features. It's very user-friendly and it has high availability, so there is comparatively less downtime. During maintenance, there is no shutdown procedure, so you can directly power off the Array and manage the shutdown process without any data loss, which is a unique feature. Managing replication and data migration is also very easy."
"The most valuable feature is replication."
"We also like the compactness, the small footprint. It takes up very little space in a data center and uses little power."
"The compression and deduplication features help to make the best use of the capacity."
"I like the speed, and I like the API and how programmable it is."
"It is nice the way ESRS works with remote support, being able to remote in and take a look at problems proactively."
"It has reduced complexity."
"It is ease to use. It performs. It's easy to provision, and It's stable."
"The most valuable feature is the fast cache with functionality rewrite."
"Being all-flash makes everything super-fast. It's also great to manage. That's the easiest part. We also have another SAN, from Pure, and the Unity is easier to manage than the Pure."
"The most valuable feature is the performance. It's still an all-flash array at a good price point."
"Scheduled components are sourced from Korea based on their quality selection, with the actual purchase taking place in Vietnam. The notable features include cache memories and MOS feeder in Dell Unity. Additionally, the storage dynamics are managed uniformly on a global scale, whether it is a simple or wide-ranging configuration."
"Quick Snapshots and cloning are key features."
"The most valuable feature of VMware vSAN is the ease of management. VMware vSAN it's a part of VMware ESXi and when you do patching for VMware ESXi, VMware vSAN receives the patches too."
"The solution's technical support is good."
"It is easy to work with, easy to handle, and easy to manage."
"I have used VMware for 15 years and I never had any problems with stability."
"It is easy to use. It is easy to implement for us, and it is also easy to maintain for the customers. It is not necessary to buy some extra devices and talk with other vendors."
"The most valuable features of VMware vSAN are that it receives updates frequently, has good compression, optimized storage, and they provide webinars on what is new. Additionally, the integration with third-party products is good and it is easy to manage."
"The performance of VMware vSAN is very good."
"The most valuable feature is the simplicity of its scalability: being able to grow it without having to make sure you get the right disks and the right nodes. The solution is also easy to manage. It's all right there in the vSphere Client. You're not going through multiple things. You don't have to know, once you've created the vSAN node. You add storage, it sees it, and you create your data storage from there. Everything is right there for you."
"It is way in excess of what we need. If anything, we could see a bit more speed. I'm just comparing it with what some of my colleagues who are implementing their own systems do."
"I want to learn more about command line usage which I have not explored much yet. However, there are many automated solutions for repetitive tasks. I would like to see additional features like performance monitoring, configuring of alerts, and the customization of alert thresholds in the next release."
"We have not seen a reduction in our TCO nor have we seen ROI."
"Automation could be simplified."
"The price could be better."
"I would love to see a true one click upgrade solution. Right now, you have to click and schedule an appointment with Pure Storage to be able to upgrade. I would love for it to automatically download, install, and fall-over every controller as it updates."
"The solution could improve by having a multi-tenant feature."
"I’d love to view the average, minimum and maximum performance in the reports (Analysis tab - Performance) but it is only graphics and you need to export data in CSV to find this information."
"I have a problem because between the Unity XT and the PowerMax, sometimes we need another product between these two products. There could be better integrated and the capacity of the size could be larger."
"Dell Unity XT could improve the compatibility of some of the features. Some of my customers had some problems. Additionally, it would be beneficial for the solution to have advanced AI and ML features."
"Licensing costs could be reduced."
"I don't know where the hybrid cloud might be going or what connectivity there is between what was recently released as far as AWS and being able to manage both of them. Maybe there is an on-prem and an AWS instance in the same window, like a single pane, but I would like to see something along those lines, where there wouldn't be two locations to manage storage."
"Unity only does compression. It would be nice if there was a deduplication feature as well. At my previous job, we used XtremIO and that was deduplication and not compression, and I think we got more out of it because the more OSs you have that are the same, the fewer copies it needs to keep of all that data. So, the deduplication would be a nice feature to have."
"It could be improved in the area of management flexibility. For example, I really need to set read-only access for LUNs, and there's no such option with Unity XT."
"The price of this product can be more cost-effective."
"We went to the PowerMax because of the needs that we have for the business. We're doing true enterprise-level storage. So we went from Unity to PowerMax to give us that tier that we were looking for."
"I see room for improvement for vSAN just around general hardware compatibility and expanding that sort of matrix."
"Based on my testing, I would like to expand deduplication to include hybrid deployments and not just for all-flash deployments."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"Lacks sufficient storage terabytes."
"I see room for improvement with vSAN in particularly in the reporting realm. Now, with vSAN 6.7, they're starting to include vRealize Operations components in the vSphere Client, even if you're not a vRealize Operations customer. So, that's really good. It exposes some really low-level reporting. I would like to see more of that. However, you have to be a vRealize Operations customer to obtain that. I would like to see more include of this included in the vSAN licensing."
"The usability is pretty good but it could use a little tweaking on the UI, with a clearer definition of exactly what some of the things do."
"The UI could certainly be better. The inside into what's actually going on with vSAN would be nice to know."
"We would like to see additional backup and recovery options added. In particular, integration with popular applications like databases."
