Used Dell 9J1X0 16GB ISCSI Controller 8GB Memory for PowerVault MD3800F
The RAID controller modules provide high-performance, advanced virtual disk configuration, and fault-tolerant disk subsystem management. Each RAID controller module contains 4GB or 8GB of mirrored cache for high availability and a battery-powered cache offload mechanism. RAID controller modules provide the following data path and enclosure management functions:
- Monitoring and controlling enclosure environment elements (temperature, fans, power supplies, and enclosure LEDs)
- Controlling access to the physical disks
- Communicating enclosure attributes and states to the host server and management station
Each RAID controller module has multiple Fibre Channel (FC) ports (labeled FC IN) for host access. The ports provide redundant host connections and support a high availability storage environment. Each port must have a small form-factor pluggable (SFP) transceiver module installed for connectivity. Various configurations can be utilized, in both single controller (simplex) and dual controller (duplex) modes, to connect the storage enclosure to hosts depending on specific redundancy needs. Each RAID controller contains a two-cell Lithium-ion Nano polymer battery backup unit (BBU). It provides power to the RAID controller module in the event of a power outage.
