Storage & Array Architectures

Performance & Advanced RAID Management

Basic Volume Grouping: RAID 0, RAID 1, RAID 10
Parity Array Support: RAID 5, RAID 6, RAID 50, RAID 60
Advanced Data Management (ADM): Supports Triple Mirroring (1 ADM) and Split Mirroring (10 ADM) topologies for extreme high-availability redundancy configurations.
Mixed Mode Capabilities: Enables simultaneous execution of structured RAID arrays alongside unconfigured raw pass-through HBA devices on the same controller board.
Device Scalability: Supports up to a total of 256 SAS or SATA end-devices when integrated with external SAS expander infrastructure backplanes.

Core Capabilities & Performance Tuning

Smart Power & Drive Handling Optimization:

The card implements highly tailored drive spin-up management alongside adaptive power profiling to reduce active operational overheads within tight server topologies.

Advanced Feature Set:
- Quick Array Initialization and Online Capacity Expansion (OCE).
- Dynamic Array Level Migration (RLM).
- Global, Dedicated, and Pooled Hot Spare allocation with automated or manual target fallback rebuild mechanics.
- Integrated Dynamic Caching algorithms paired with Native Command Queuing (NCQ).
Enclosure Interfacing: Native SES (SCSI Enclosure Services) and SGPIO backend enclosure management routines.
Drive Block Compatibility: Fully handles native 4K sector size topologies (4Kn) in tandem with legacy 512-byte (512e/512n) drive configurations.
Power Savings: Built-in dynamic controller power management system, delivering up to 30% aggregate reduction in structural thermal dissipation.

Operating System & Management Infrastructure

Software Management Suite

maxView Storage Manager: Web-based centralized graphical user interface (GUI) designed for remote configurations, firmware deployments, and email SMTP notification parameters.
ARCCONF CLI: Scriptable command-line utility for system integration and automated health monitoring.
Pre-Boot Utilities: Legacy BIOS configuration console (Ctrl+A) along with updated UEFI Human Interface Infrastructure (HII) extensions.
