Netapp Hardware Components / Fundamentals

NVRAM:

NVRAM retains data in the event od power loss.

System Memory:

System Memory is the main memory that holds current programs and data that are in use.

CPU:

The Central Processing unit (CPU) is the man processing chip, or brains of the system.

Power supplies:

Power supplies convert building power into lower voltages required by the system.

System fans:

System fans transfer heat awat from sensitive areas and out of the system.

Expansion adapter cards:

Expansion adapter cards extend the system's control over peripheral devies. An example is the NIC or network interface card.

Ethernet:

The on-board Ethernet connection and network interface card (NIC) provide access to networks and network protocols.

Console:

The console connection is a physical or remote terminal that monitors and controls a Netapp system.

Boot Device :

The system uses the boot device to initialize the system at startup.

Disk Drives:

Two or more disk drives are used to store and retrieve data.

ESH/LRC Modules:

When the head is attached to one or more disk shelves, ESH and LRC modules are the connection point between the head and disk shelves.
