Featured Reviews

Jörg Köhler - PeerSpot reviewer
Consulting benefits from robust consulting while also recognizing the need for improved disk management
When it comes to optimization, that's one of the weaker points of Citrix XenServer, especially regarding disk management, which is somewhat clumsy. Backup-related issues and disk management should be improved. Especially concerning backup, as discussions with Veeam engineers about Citrix XenServer backup strategy indicate there might not be a solution from Veeam soon. License optimization is not such a significant problem, but licenses are quite complicated. Vendors constantly invent new license models, making it difficult to order the correct licenses needed. There is not a big difference between Citrix and VMware products because Citrix can implement Windows and Linux anyway.

Atif Najam - PeerSpot reviewer
Offers mobility and you can seamlessly move a VM between different PowerVM instances
PowerVM is likely one of the most stable hypervisors available, albeit highly specialized. However, it is solely command-line based. When someone manages virtualization as a whole, they typically expect a graphical user interface (GUI) for configurations. This is the case for Hyper-V, XenServer, and VMware. But with PowerVM, you need to understand and memorize commands to operate the hypervisor. I believe PowerVM should have a GUI; that would be a significant improvement.
