Installing the Altos RAID-enabler
(optional)
This section explains how to install the Altos RAID-enabler (iButton)
and an iTBBU.
The iTBBU (Transportable Battery Backup Unit) shown below is for your
reference only. You have the option to install either an iTBBU or an
unbuffered ECC DDR DIMM into the DIMM slot.

system. To purchase an Altos RAID-enabler (iButton) and iTBBU,

DIMM or iTBBU to subsequently store data from the HDD to the DIMM.
iTBBU includes a battery pack attached onto the memory module that
protects data in the cache memory in the event of a power failure.
