Storage basic defination

👉 Raid (Redundant Array of Independent Disks): Redundant solution because it allows data to be written to multiple hard disks at the same time. In addition, RAID has many variations that allow to significantly increase the speed of data retrieval from the hard disk, example: RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks;

👉Storage pool: capacity aggregated in a shared storage environment from disparate physical storage resources.

👉 Storage volume: an identifiable unit of data storage. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical interface. 

👉  Pwwn (port world wide name): a unique identifier for each Fiber Channel port presented to a Storage Area Network (SAN)

👉  iRMC: Integrated Remote Management Controller.

👉 iDRAC (The Integrated Dell Remote Access Controller) designed for secure local and remote server management and helps IT administrators deploy, update and monitor servers anywhere, anytime.

👉 iLO (Integrated Lights-Out): Securely configure, monitor, and update your HPE ProLiant servers seamlessly, from anywhere in the world.

👉 SNMP (Simple Network Management Protocol): internet standard protocol used to monitor and manage network devices connected over an IP. SNMP is used for communication between routers, switches, firewalls, load balancers, servers, CCTV cameras, and wireless devices.
