Geovision 72-AR123-001 Areca Arc-1220 8-Port RAID Card
Overview
The Geovision 72-AR123-001 is an Areca Arc-1220 PCI Express RAID controller designed to expand storage capacity and redundancy in Geovision NVR and server systems. This 8-port SATA card handles hardware-based RAID processing — offloading array operations from the CPU — which is critical when recording 24/7 across high-density camera systems. Install this card into an available PCIe slot to multiply your storage capacity while maintaining fault tolerance.
Compatibility
The 72-AR123-001 integrates with Geovision NVR systems and servers that require expanded storage capacity and RAID redundancy. Verify your system has an available PCI Express slot and sufficient power delivery before ordering. The card's 8 SATA ports connect directly to physical drives; ensure your chassis accommodates the drive count you intend to attach. Consult your Geovision NVR documentation for specific model compatibility and any firmware updates required post-installation.
Key Specifications
RAID Modes: Supports RAID 0 (striping for speed), RAID 1 (mirroring for redundancy), RAID 3, RAID 5 (striped with parity — best balance of speed and protection for most surveillance builds), RAID 6 (dual parity — survive two concurrent drive failures), and RAID 10 (mirrored pairs). Choose RAID 5 for most installations; RAID 6 if uptime is non-negotiable and drive rebuild time is a concern.
Interface: PCI Express connection ensures full-bandwidth communication with the host system. Advanced cache management optimizes read/write performance across the array — meaningful when serving playback requests while recording from dozens of cameras simultaneously.
Hardware Processing: The card handles RAID calculations in dedicated silicon, not CPU cycles. This separation is the difference between smooth 4K multi-camera playback and stalled video feeds when the system is under load.
Installation Notes
Power the card via available 12V/5V rail in your power supply — verify the system has headroom before installation. Secure the card firmly in its PCIe slot using the mounting bracket. Install drives into their SATA ports and configure the RAID array through the card's management interface before bringing the system online. Refer to the Areca user manual for detailed initialization and monitoring procedures.
