ausExternalRaidDeviceNumberOfChannels
Module: ADAPTEC-UNIVERSAL-STORAGE-MIB
OID (symbolic): ADAPTEC-UNIVERSAL-STORAGE-MIB::ausExternalRaidDeviceNumberOfChannels
OID (numeric): 1.3.6.1.4.1.795.14.1.412.1.1.3
Node type: OBJECT-TYPE

Access: read-only
Description: The number of back-end channels present on this external RAID controller.
What is ausExternalRaidDeviceNumberOfChannels?
This OID indicates how many back-end SCSI or SAS channels the external RAID controller has available for connecting disk drives, typically a value between 1 and 32. Storage engineers care about this because it determines the maximum number of physical drives that can be connected to that RAID controller, which limits expansion capacity. For example, a value of '16' means the RAID controller can support up to 16 separate drive channels for storage expansion.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.795.14.1.412.1.1.3 snmpwalk -v2c -c public <target> ADAPTEC-UNIVERSAL-STORAGE-MIB::ausExternalRaidDeviceNumberOfChannels
Get a specific instance (index 1):
