2. โครงตัวถังแบบเปิด: Open the computer chassis to access the motherboard's PCIe slots.
3. ใส่ HBA: Locate an available PCI-Express 2.0 x8 slot or higher (e.g., x16) and carefully insert the RocketRAID 2720SGL HBA until it is firmly seated.
4. บัตรที่ปลอดภัย: Secure the HBA with the bracket screw. If using a low-profile chassis, replace the standard bracket with the included low-profile วงเล็บ
5. เชื่อมต่อไดรฟ์: Connect your SAS or SATA drives to the two internal Mini-SAS (SFF-8087) ports on the HBA using appropriate Mini-SAS to SATA breakout cables (not included). Each port supports up to four drives.
6. ปิดแชสซี: ปิดฝาเคสคอมพิวเตอร์และเสียบปลั๊กไฟกลับเข้าไปใหม่

3.2 การติดตั้งไดรเวอร์

After physical installation, power on your system. The operating system will detect new hardware. Install the appropriate drivers from the included Software CD or download the latest drivers from the HighPoint website for your specific operating system (Windows, Linux, FreeBSD).

• หน้าต่าง: Follow the on-screen prompts to install drivers. It is recommended to download the latest drivers and Web interface from the HighPoint webเว็บไซต์.
• Linux/FreeBSD: Refer to the Quick Installation Guide or HighPoint's online documentation for specific driver installation procedures for your distribution.

3.3 BIOS Configuration (Optional)

The RocketRAID 2720SGL has its own BIOS. During system boot, you may see the card's BIOS post screen. Advanced configuration or firmware updates can be performed via the BIOS or the Web GUI. If you encounter boot issues when using multiple RAID controllers, you may need to adjust specific BIOS settings:

• Access the RocketRAID BIOS by pressing the designated hotkey (often Ctrl-H) during the card's boot-up sequence.
• If the RocketRAID is ไม่ your boot drive, consider disabling "EBDA Reallocation" and "INT13" settings within the RocketRAID BIOS to prevent conflicts with other controllers.
• If the RocketRAID is your boot drive, only disable "EBDA Reallocation."
• บันทึกการเปลี่ยนแปลงและออกจาก BIOS

Note: Firmware updates are often best performed from a bootable DOS environment if conflicts arise with other RAID controllers. Refer to HighPoint's support documentation for detailed instructions on creating a bootable USB for firmware updates.

4. Operating the RocketRAID 2720SGL

4.1 การกำหนดค่า RAID

The RocketRAID 2720SGL supports various RAID levels to optimize performance or data redundancy:

• RAID 0 (การแบ่งสตริป): Maximizes performance by striping data across multiple drives. No redundancy.
• RAID 1 (การมิเรอร์): Provides data redundancy by mirroring data onto two drives.
• RAID 5 (การสตริปด้วย Parity): Offers a balance of performance and data redundancy. Requires at least three drives.
• RAID 10 (การแบ่งข้อมูลแบบสไตรปิ้ง): ผสานการทำงานของ RAID 0 และ RAID 1 เพื่อประสิทธิภาพและความปลอดภัยของข้อมูล ต้องใช้ฮาร์ดไดรฟ์อย่างน้อยสี่ตัว
• RAID 50 (Striping of RAID 5 arrays): Combines RAID 0 and RAID 5 for higher performance and redundancy with more drives.
• JBOD (แค่กลุ่มของดิสก์): Treats individual drives as separate entities without RAID functionality.

RAID arrays can be configured using the Web GUI, CLI, or the card's BIOS utility.

4.2 อินเทอร์เฟซการจัดการ

HighPoint provides several tools for managing your RAID arrays:

• Web GUI (HighPoint RAID Management - HRM): A web browser-based interface for local and remote monitoring and configuration. Access typically via a specific IP address or localhost port after driver installation.
• CLI (อินเทอร์เฟซบรรทัดคำสั่ง): For advanced users and scripting, allowing management through command-line commands.
• BIOS Utility: Accessible during system boot (Ctrl-H) for basic RAID creation and management before the operating system loads.

คุณสมบัติขั้นสูง 4.3 ประการ

• การขยายขีดความสามารถออนไลน์ (OCE): Allows expanding the capacity of an existing RAID array by adding more drives without data loss or downtime.
• การย้ายข้อมูลระดับ RAID ออนไลน์ (ORLM): Enables changing the RAID level of an existing array (e.g., from RAID 0 to RAID 5) without data loss.
• Native Command Queuing (NCQ): Optimizes the order of read/write commands for improved performance with SATA drives.
• SMART (เทคโนโลยีการตรวจสอบ วิเคราะห์ และรายงานตนเอง): Monitors drive health and predicts potential failures.
• Disk Scrubbing: A process to verify data integrity and correct errors on RAID arrays.
• 64-bit LBA Support: For RAID arrays larger than 2TB.

5. การบำรุงรักษาและการตรวจสอบ

Regular monitoring of your RAID array and connected drives is crucial for data integrity and system stability.

5.1 Array Monitors, Alerts, and Indicators

• Hard Drive LED Indicators: Activity and Failed LEDs (if applicable to your system/enclosure) provide visual status.
• SMTP Email Notification: Configure email alerts for critical events and error reporting.
• Alarm/Buzzer Alerts: Audible alerts for drive or array failures.
• SAF-TE (I2C) and SGPIO: Enclosure management support for compatible drive enclosures.
• SHI (Storage Health Inspector): Drive analysis driven from S.M.A.R.T. data for proactive maintenance.

5.2 ความเข้ากันได้ของไดรฟ์

For optimal performance and reliability, it is recommended to use enterprise-grade or RAID-specific hard drives. Desktop-class drives may exhibit unexpected behavior or become unresponsive under heavy load in a RAID environment due to differences in error recovery control (ERC) or Time-Limited Error Recovery (TLER) features.

6 การแก้ไขปัญหา

This section addresses common issues you might encounter with the RocketRAID 2720SGL.

6.1 System Fails to Boot or Hangs at POST

• Multiple RAID Controllers: If you have another RAID controller in your system, conflicts can occur. Try disabling "EBDA Reallocation" and "INT13" in the RocketRAID BIOS if it's not your boot drive. If it is your boot drive, disable only "EBDA Reallocation."
• การเข้าถึง BIOS: If the system hangs before you can access the RocketRAID BIOS (often by pressing Ctrl-H), try pressing the จบ key immediately when the RocketRAID BIOS screen appears to bypass it and proceed with boot.
• ปัญหาการอัพเดตเฟิร์มแวร์: Ensure firmware is up-to-date. If a Web GUI update caused issues, consider performing the update from a bootable DOS environment as described in HighPoint's support documentation.

6.2 Drives Become Unresponsive or Drop Offline

• ประเภทไดรฟ์: Using desktop-grade hard drives in a RAID environment can lead to instability. These drives may not handle error recovery in a timely manner, causing the controller to mark them as unresponsive. Use enterprise or RAID-specific drives for best results.
• การเดินสาย: Ensure all Mini-SAS to SATA breakout cables are securely connected and are of good quality. Faulty cables can cause intermittent drive connectivity issues.
• ความร้อน: The controller chip can generate significant heat. Ensure adequate airflow within your chassis, especially around the HBA's heatsink. Consider additional cooling if temperatures are consistently high.

6.3 Audible Alarm Sounds Constantly

• This typically indicates a drive or array failure. Check the Web GUI or BIOS utility for specific error messages.
• Verify all drives are properly connected and functioning. A drive that is not fully initialized or has errors can trigger the alarm.
