Product Description
The "8-Port 12Gb SAS RAID Card (with 2GB cache, PMC) (CTO&BTO)" is a high-performance storage controller designed for enterprise servers and storage systems. Below is a detailed breakdown of its specifications, features, and use cases:
1. Key Specifications
- Interface & Ports:
- 8 physical ports supporting 12Gb/s SAS (Serial Attached SCSI) interface, compatible with SAS-4, SAS-3, and SATA drives.
- Each port can connect to a SAS expander to support more drives (e.g., up to 22 drives per port with expanders, depending on the setup).
- RAID Support:
- Hardware RAID levels: 0, 1, 5, 6, 10, 50, 60, and JBOD (configurable via firmware or management tools).
- Supports hot-spare drives, bad block relocation, and background rebuild for data redundancy.
- Cache Memory:
- 2GB DDR4 cache memory for improved read/write performance, with optional battery backup unit (BBU) or flash backup (not included, may need to be ordered separately).
2. Controller Technology
- Processor: Powered by a PMC (Pericom/Microchip) SAS controller chip, optimized for low latency and high throughput in enterprise workloads.
- PCIe Interface: Typically uses a PCIe 3.0 x8 or x16 slot (check server compatibility), supporting full-duplex data transfer at 12Gb/s per port.
3. Management & Features
- Software Support:
- Web-based management tools (e.g., PMC's RAID management utility) for configuration, monitoring, and alerts.
- Compatibility with server management systems (e.g., IPMI, Redfish) for remote administration.
- Advanced Features:
- Write-back/write-through cache policies to balance performance and data safety.
- SSD caching support (if the controller firmware allows) to accelerate frequently accessed data.
- TRIM command support for SSDs in RAID configurations.
