Discovery of CIs and relationships for direct attached and multipath block storage on Linux hosts
Discovery collects information on Direct Attached Storage (DAS), Storage Area Networks (SAN), and Network Attached Storage (NAS) from specialized devices, such as Storage Arrays, Fibre Channel Switches, iSCSI disks, and from host operating systems, such as Linux.
- Direct-attached storage (DAS), network-attached storage (NAS), or storage area network (SAN).
- NAS or SAN storage that is discovered via a Storage Management Initiative Specification (SMI-S) and Common Information Model (CIM).
- Virtual storage for VMware EXS servers and Linux Kernel-based Virtual Machines (KVM). Discovery maps this storage to the underlying physical storage.
- File systems (local and NAS).
- Disks (both SAN disks and DAS drives). Fibre Channel (FC) HBAs and ports.
- Linux Volume Manager (LVM) volumes. LVM volume data resides in the Storage Pool [cmdb_ci_storage_pool] table.
- Veritas Volume Manager disks, subdisks, disk groups, plexes, and volumes.
For a detailed discussion of how Discovery maps dependencies and relates storage CIs to one another, see the attached document for direct attached and multipath, block storage.
