The 7420 M2 has two SAS-2 system boot drives in slots 0 and 1, configured as a mirrored pair. Up to four SAS-2 read cache SSDs may fill slots 2 through 5, in order. In a 7420 M2 cluster, the number of SSDs installed in each controller can vary.
7420 controllers have two SATA system boot drives in slots 0 and 1, configured as a mirrored pair. Zero, two, three, or four read cache SSDs, may optionally fill slots 2 through 5, in order. In a 7420 cluster, the number of SSDs installed in both controllers must match.
For information about supported HDDs and SSDs, see the Oracle Systems Handbook.
