ARC-1880/1882 series controller field-proven compatibility with
operating systems, motherboards, applications and device drivers.
Easy RAID Management
The controllers contain an embedded McBIOS RAID manager that
can access via hot key at M/B BIOS boot-up screen. This pre-boot
McBIOS RAID manager can use to simplify the setup and manage-
ment of RAID controller. The controller firmware also contains a
browser-based McRAID storage manager which can be accessed
through the Ethernet port or ArcHTTP proxy server in Windows,
Linux, FreeBSD and more environments. The McRAID storage
manager allows local and remote for all storage configuration and
management needs from standard web browser. The ArcSAP quick
manager can scan for multiple RAID units in the local and remote
systems and provide an effective mechanism to configure and
monitor your RAID units.
