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."The most valuable feature of this solution is reliability."
"Technical support has been helpful and responsive."
"The system allows for seamless learning experiences, facilitating quick and easy cloning of environments within minutes."
"The Pure1 component is most valuable at this point in time when comparing it with EMC. Pure1 is where you can have your diagnostics in the cloud, so you can look at things from your mobile phone."
"The most valuable feature of this solution is its ease of use."
"Pure FlashArray X NVMe has low latency and high Ops. It is an evergreen model."
"Pure FlashArray X NVMe helps to improve our processing speed. It is user-friendly and easy to use."
"What I really like about this program, is that it is easy to use and easy to configurate."
"The most valuable aspects of this solution are its stability, performance, and ease of updating."
"It has good performance."
"It is simple to use and easy to manage. We don't touch it after we set it up."
"Via a click, we can deploy a data store or LUN to the ESX host. We can also deploy VVOLs to the ESX server."
"It is easy to manage overall. It is all web-based. It has a an easy, nice dashboard. I receive emails if there are issues. When there are any updates, I receive emails. I can either do them on my own, but normally I schedule them with Dell EMC and they remote in, then it's done."
"It does great deduplication. From a storage perspective, we save money being able to dedupe right on the disk"
"The technical support is very professional and provides quick responses."
"It has improved the utilization of our own internal resources and performance across our managed service platform, meeting our customers SLAs."
"The solution fits well with my requirements."
"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."
"The most valuable feature for our customers is vMotion. It allows them to shut down virtual machines and migrate them to others servers."
"This product has very good performance when it comes to virtualization storage and works well with solutions such as SAP HANA, Exadata, Hadoop, and Big Data Analytics."
"VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products."
"The ability to have a disaster recovery option for our end-users by being able to use VDI and the vSANs, and the ability to do replication across multiple data centers, are valuable to us."
"The installation is very easy."
"It is easy to work with, easy to handle, and easy to manage."
"In the next release, I would like to see real-time analytics for further insight into consumption models."
"The software layer has to improve."
"The tool's pricing is higher than competitors."
"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."
"We need better data deduplication."
"In terms of what needs improvement, the dashboard and management could be simplified."
"Efficiency improvements would always be welcome, but I'm not sure if they could get more efficient."
"The UI for this solution needs to be improved."
"Stability is the problem. We've had stability issues with it. We've had problems with the iSCSI interface. We've had it for two years now and for two years we've had problems where a service processor will drop, we'll lose connectivity to LUNs, we'll lose connectivity to the storage, issues like that. No matter how we've tried to chase it down, everybody just points fingers at each other. The only thing that changed in our environment was that the Unity solution was installed."
"We've got massive issues at the moment with IBM AIX. It's not stable. We have a lot of disk errors, production crashes sometimes."
"Software updates have to be downloaded to the root of the device. This pushes the available space to 95% utilization."
"One area of improvement is replication. We are also using Oracle virtual machines, and when you are using systems from other vendors, the process of replicating from Unity through OLVM is more laborious than when we were using VPLEX."
"I think that they could do a better job of testing on the back-end, for the code revisions. I've heard of some issues down the line where people have upgraded to the latest code and there were bugs in it, and they had to release a subsequent code fix."
"The price of this product can be more cost-effective."
"The Host LUN ID is sequential by access in the hosts. When one LUN needs access by many hosts (for cluster purposes), in some cases the Host LUN ID remains different on each host."
"The monitoring part could be better. With EMC storage systems - or Unity and VPLEX, because I'm using them, for the moment - the monitoring part is very difficult. They should improve this to have a better reporting system."
"It needs to be vanilla. There shouldn't be any custom drivers, any custom anything. It should just be, "Hey, you know what? These drivers are going to work for this version, the next version, and the following version after that." That's the difficulty in this. It takes too much upkeep... The main issue is drivers. Every time we move to a new vSAN version, we're having problems finding the correct drivers for the vendor."
"The monitoring feature in VMware vSAN could be better."
"Pricing is something of a concern."
"I would rate the stability a seven out of ten."
"Integration could be better."
"Disaster recovery needs to be improved, when there is a crisis, there is a problem with what is the quickest way to get out of it."
"The only thing that can be improved is the cost."
"I would love for this product to be cheaper and easier to configure."
