HDD Modules in a QFX3100 Director Device
The two 2-terabyte (TB) hard disk drive (HDD) modules in each QFX3100 Director device provide storage for the Director device and the QFabric System. The four HDD modules in the two QFX3100 Director devices participating in a Director group operate in a redundant array of independent disks (RAID) system to synchronize directories or files across the HDD modules.
Each HDD module can be installed in one of the two top slots on the front panel of the QFX3100 Director device. The QFX3100 Director device is shipped with two HDD modules.
HDD modules are field-replaceable units (FRUs).
