Well, I don't know the answer to your question about that pattern, but I can say that the earliest DRAC I know of would be the DRAC5 for 9G. The tenth gen also used DRAC5. I checked both the R900 and R300 documentation and the DRAC5 was implemented on the high end and mid-grade models. The 9th and 10th gen servers are the only ones I know of that had DRAC generational crossover.If a DRAC4 does exist, I've never seen it (it could exist under another name, but I don't want to put my foot in my mouth). I'd think you could use DRAC5 as a backstop.   The pattern does seem to hold and I wouldn't expect that to change now, but I'm not in a position to comment on if they would take a new approach with, say 15G, for sake of argument. I can say that from a support angle, when people tell me they need help with DRACX, in my head, I immediately translate to Server gen Y, and it hasn't been inaccurate so far. 
Hi, I'm looking for a way to map the idractype as returned by: /opt/dell/srvadmin/sbin/racadm getconfig -g idRacInfo into the idrac version (6,7,8 or 9) The idrac manual for version 7 says: [IMAGE] That's good, but now we're on gen14 and the newer manuals don't seem to have that information. Is there an authoritative source for these mappings currently? Thanks
