flash module is selected for better performance and less power consumption. In
Cache‐to‐Flash recovery phase, BIOS will check C2F flag status. If C2F flag is ON, I/O cache
data will be recovered from the M.2 flash module and then continue normal booting. If C2F
flag is OFF, the normal booting process continues. Compared with traditional BBM solution
of 72 hours standard, Cache-to-Flash technology is more efficient, less risky and consumes
less power.

Features of the Cache-to-Flash Module
The optional Cache-to-Flash module comes with a M.2 flash module and either a BBM or a
SCM. All modules are hot pluggable with zero system downtime for extra availability and
reliability. M.2 flash module can be plugged in on the left hand side from the rear of the
chassis. Power module can be plugged in on the right hand side from the rear of the chassis.
Please be noted that the BBM can protect up to 64GB system memory per controller; the
SCM can protect up to 16GB system memory per controller. If your system memory is
higher than 16GB, please select BBM solution.
