For those who are running VSAN in their environment, I would urge you to have a look at this KB article: Storage Controllers previously supported for VSAN that are no longer supported (2081431). This KB article describes a list of disk controllers which have been removed from the VSAN HCL because of the shallow queue depth. I described in an article a while back “Why Queue Depth matters” and this is also reiterated by Rakesh from VSAN product management in this blog article on the vSphere blog.
If you have purchased Virtual SAN for use with these controllers, please contact VMware customer care for next steps.
