Chapter 1. Maintain DE2000H or DE4000H hardware
For the DE2000H or DE4000H storage system, you can perform maintenance
procedures on the following components.
1.1. Batteries
Each controller canister includes a battery that preserves cached data if the AC power fails.
1.2. Controllers
A controller consists of a board, firmware, and software. It controls the drives and implements the
System Manager functions.
1.3. Canisters
Canisters consist of three different types: power-fan canisters (power supplies) that supply a
redundant power source and adequate cooling in a 12-drive or 24-drive controller shelf or drive
shelf; power canisters that are used for power redundancy in a 60-drive controller shelf or drive
shelf; and fan canisters that are used for cooling the 60-drive controller shelf or drive shelf.
1.4. Drives
A drive is an electromagnetic mechanical device that provides the physical storage media for data.
1.5. Host interface cards (HICs)
A host interface card (HIC) can optionally be installed within a controller canister. The DE2000H or
DE4000H controller includes built-in host ports on the controller card itself, as well as host ports on
the optional HIC. Host ports that are built into the controller are called baseboard host ports. Host
ports that are built into the HIC are called HIC ports.
1.6. Host port protocol
You can convert the protocol of a host to a different protocol so that compatibility and
communication can be established.
