NOTE: PERC H755 adapter and PERC H755 MX supports either SAS, SATA, or NVMe drives depending on the backplane/server configuration.
NOTE: PERC controller supports only conventional magnetic recording (CMR) drives, and does not support shingled magnetic recording (SMR) drives.
NOTE: PERC H755 family of controllers currently support SEKM starting with firmware version 52.14.0-3901.
NOTE: For information about the number of drives in a disk group per virtual disk, see Summary of RAID levels
NOTE: As 14G PowerEdge Servers do not support Gen 4 speeds, PERC H750 adapter SAS will downtrain to Gen 3 speeds.
