Areca ARC-1883-CAP (Flash Based Back-up Module)

The ARC-1883-BAT/CAP kit includes the Flash-based module (FBM), and one cable. The FBM features NAND flash memory and super capacitor technology that provides cache offload capability to protect cached data in case of system power loss. The module is mounted super-capacitor pack or battery that provides power for the backup of your data. When the module detects loss of power, the super capacitor keeps parts of the ARC-1883 RAID controller active long enough to allow cache data to be copied to the flash memory. The module attaches directly to the 12 Gb/s SAS RAID controller by the cable.

For ARC-1883I, ARC-1883X, ARC-1883LP, ARC-1883IX-12/16/24

FBM with Battery

1. Low profile bracket is also provided.

2. The FBM will occupy one PCI slot on the host backplane.

Flash-based Backup Capacity

The FBM backup capacity is defined as the maximum duration of a power failure for which data in the cache memory can be written into the flash on ARC-1883-CAP/BAT. The FBM can support up to 2 GB memory chips that installed on the 12Gb/s SAS RAID controller.

Operation

1. There are no manual procedures for FBM conditioning or preconditioning to be performed by the user.

2. No further power is required once the super capacitor is fully charged.

Note: Do not remove FBM while system is running.
