Product Description

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.
