By default, M-Series appliances are shipped with the first RAID
1 disk pair installed in bays A1 and A2. In the software, the disk
pair in bays A1 and A2 is named Disk Pair A. The remaining bays
are named sequentially: Disk Pair B, Disk Pair C, and so on. For
example, the M-500 appliance supports up to 12 disk pairs. You can install pairs of 2TB or 1TB disks within
the same appliance; however, disk size must be the same for both
drives within each pair.
The Panorama virtual appliance supports up to 12 virtual logging
disks for 24TB of storage capacity.
After you add disk pairs, the Log Collector redistributes its
existing logs across all the disks, which can take hours for each
terabyte of logs. During the redistribution process, the maximum
log ingestion rate is reduced. In the
Log Redistribution State column indicates the completion status
of the process as a percentage.
If you use an SNMP manager for centralized
monitoring, you can see loggings statistics in the panLogCollector MIB.
