Cooling modules provide the following features:
■
Fast removal and replacement times without the need to turn off the storage
shelf.
■
Electronic fan speed control to the fans.
■
Redundant serial interface connections to the rest of the storage shelf system.
■
Cooling module redundancy
■
Redundancy includes:
■
Maintaining the cooling function of the cooling module in the event of a single
fan rotor failure.
■
Maintaining the normal operation of the cooling module if one cooling control
or fan controller module fails.
■
Automatically switching fan speeds to Full/High mode if the cooling module
control unit fails.
■
Maintaining the normal operation of the storage shelf for two minutes when
a cooling module is swapped out due to a failure.
5U84 Storage Shelf Power Supply Units
Veritas 5U84 Storage Shelves includes dual Power Supply Units (PSU) that provide
redundant power to the storage shelves. If one PSU fails, the storage shelves
continue to operate as the second PSU continues to supply the storage shelf with
power.
PSUs are hot-swappable. You can replace a faulty PSU while the storage shelf is
running. However, you must complete the PSU replacement procedure within
two
minutes
after you remove the faulty PSU.
Veritas 5U84 Storage Shelf chassis are keyed to prevent PSUs from being inserted
upside down.
