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):

snmpget -v2c -c public <target> 1.3.6.1.4.1.795.14.1.412.1.1.3.1
snmpget -v2c -c public <target> ADAPTEC-UNIVERSAL-STORAGE-MIB::ausExternalRaidDeviceNumberOfChannels.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ausExternalRaidDeviceNumberOfChannels.1
