We performed a comparison between IBM FlashSystem and VMware vSAN based on real PeerSpot user reviews.
Find out what your peers are saying about Dell Technologies, NetApp, Nasuni and others in NAS."The speed, performance, and stability are the best features of IBM FlashSystem."
"The initial customer technical support was efficient and effective."
"The performance of the All-Flash System is very good. There is more enhanced performance and data production in the solution, which I appreciate."
"The maintenance service and support from IBM is very good."
"Ability to manage third-party arrays and virtualise them: One screen to control multiple arrays. Simplified administration."
"The speed of the unit is its best feature. It performs very well."
"The speed and the ease of installation are the most valuable features."
"The most valuable features of IBM FlashSystem are performance and security."
"I like the scalability and the fact that it reduces your total cost for storage over several years."
"It is simple to manage, very easy to implement and troubleshoot in case of any failures."
"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."
"The most valuable feature of VMware vSAN is you do not have to use additional hardware for storage. The operation of VMware vSAN does not take a lot of effort. If you have VMware technology on your site, then it's easy for the operational support of the system."
"Storage virtualization software with a good storage management feature. It's a scalable and stable software."
"VMware vSAN is easy to implement in a VMware environment and it is not expensive."
"The simplicity, as well as the integration with virtualization."
"VMware comes with different stacks like VMware Cloud Foundation, which is integrated with different VMware modules. There's interoperability between VMware products."
"GUI interface should be enhanced more as there is some issues in copy services."
"AHV is Acropolis Hypervisor – A relatively new Hypervisor, robust and stable as VMware vSphere, has built-in advanced analytics and powerful operations, Self Service Portal and components for DevOps included, managed by a single pane of glass (Prism) via HTML5 and it is free of charge – That is why Nutanix is so advanced and revolutionary."
"The generic functionality of IBM FlashSystem, IBM always dismisses using file share or sharing protocols inside their storage hardware, and they only focus on the block-level storage."
"Customization features must be improved."
"The basic setup can be challenging when it comes to certain IP addresses and the configuration of the IP. You have to go in to different menus to makes changes and ensure it is stable."
"I would like to see an improvement in the handling of large amounts of rights."
"The interface could improve in IBM FlashSystem."
"The storage capacity of this solution could be improved."
"A vSAN cluster must have compression and deduplication to be an all-flash array, but it's not supported with a hybrid array. Deduplication and compression work better with an all-flash array, so I think that VMware should give customers the option to activate and support this feature for hybrid arrays. Other products like Nutanix support this."
"The stability needs to be improved."
"The biggest room for improvement I see in vSAN is the lack of SAN connectivity. I've kind of joked around that there is no "SAN" in vSAN. And it's something that we've worked to try and introduce some options for, and we're going to continue to work towards that."
"VMware vSAN could improve by having better integration with other vendors and the storage is limited, I prefer it to the traditional storage."
"While I like the replication and compression features, there is a problem with them running too slowly."
"It doesn't seem like it gives the performance that an actual SAN would give for heavy IOPS, read/writes."
"I would like more integration with the hardware when it comes to disc types and supporting the newer types of storage."
"This product is very expensive."
