SigfridCecillon

Owner at Arsium

High availability and user-friendliness enhance infrastructure health and redundancy

I would rate technical support from DataCore SANsymphony a 10. Each time I contact the technical support, it's when I don't have a choice because it's very difficult for me on site, and each time, I have good people online who are able to help me solve the problem. Usually, the problems are not very technically difficult, but sometimes they are, and the support team is still there to help us resolve them. The majority of the problems are linked to licensing, so when the license has expired or the number is not correct, they are proactive and change things live, which is very good.

Solution delivers impressive speed and performance with room for better management tool integration

Senior Technical Support Engineer at a tech services company with 10,001+ employees

Microsoft should improve the management aspect of Microsoft Storage Spaces Direct, as we have raised multiple recommendations but they often refer us to use Microsoft Arc instead of Windows Admin Center. The licensing for Microsoft Storage Spaces Direct could be improved to be clearer, as calculating license requirements requires significant expertise; even Microsoft resources do not provide the full picture needed for licensing, leaving gaps that become evident once we move to deploy solutions. Improving the Windows Admin Center to be more stable with alert notifications and management capabilities for Microsoft Storage Spaces Direct would greatly benefit users, as we have not seen any recent product updates since the announcements last November.
