The disk drive carrier supports one inch, SCA-2 direct
attach disk drives. The SANbloc Series can hold up to
fourteen disk drive carriers. The disk drives can be hot
swapped and the disk drive carriers provide for blind mating.
The SANbloc Series has two power supplies for normal
operation, providing redundancy of the power system. The
power supplies can be hot swapped. The power supplies
provide 673 Watts continuous output power and 853 Watts
peak output power. The power supplies have a universal
input voltage range, and active current sharing. Power factor
correction, over current and over voltage protection is also
provided, along with AC voltage brown-out detection. The
power supplies have individual power inputs.
Cooling is provided by the two Advanced Cooling
Modules (ACMs) located at the rear of the enclosure. Each
of the ACM units contain two variable speed fans. The
enclosure requires four fans for normal operation, but will
operate correctly with one fan failed (redundancy is lost if
one fan is failed in either ACM), however, it is recom-
mended that the failed fan be replaced as soon as possible.
The ACM units can be hot swapped. The LS Module
monitors and controls the speed of each fan. The speed is set
