Asempris,  I apologize, the C2100 doesn't support Cachecade, which is the feature you are describing of using the SSD's for cache. You can also find more information on the C2100 here - [URL]  Let me know how it goes.  
Hi, On a C2100 with an LSI 9260-8i, what are the requirements for ssd cache to work? I'd add 2 ssd drives (internally) to enable this feature but I'm not sure if besides the ssd drives I'll need anything else or if it's even supported on this server with the 9260-8i Thanks,
