I'm no SCSI wizard, but bear in mind that these particular lines are only warnings and it is quite common for commands to not be understood by the storage layer. Not all devices will support all the commands being sent. The important lines that might be of concern in your log output are the ones with "state in doubt; requested fast path state update...". These lines indicate that a command timed out and the state of the device is now "in doubt", but as you mentioned these lines refer to your CD-ROM, etc. and so are of no concern (they are also still only informational warnings!)
The lines that do relate to your local disk indicate that an ATA pass through command was not understood by the actual device. Since the device is a logical raid1 made up of two underlying SSD's, this is probably to be expected!
I can't tell you exactly what the command was as I couldn't work it out. The command sent appears to be 0x4124003fb980, but I don't know what that is, apart from "0x41" could be the SCSI op code for WRITE SAME (10) -- note: not to be confused with WRITE SAME (16) - 0x93, i.e. the VAAI primitive (http://kb.vmware.com/kb/1021976) 
Is your primary concern simply that the local disk has not been detected as SSD? If so you might be able to work around that: http://www.virtuallyghetto.com/2011/07/how-to-trick-esxi-5-in-seeing-ssd.html
Hope this helps!
