• Seagate Exos X20 20TB SAS Hard Drive (Model: ST20000NM002D)
• Note: The actual capacity may vary slightly due to formatting and system overhead.

Cables, mounting screws, and documentation are typically sold separately or provided by your system integrator.

4. 설정 및 설치

4.1. 전제 조건

• A server, workstation, or NAS enclosure with available 3.5-inch drive bays.
• A compatible SAS Host Bus Adapter (HBA) or RAID controller. Ensure the HBA supports 12Gb/s SAS and drive capacities of 20TB or higher.
• Appropriate SAS data cables (e.g., SFF-8643 to SFF-8482 for direct connection, or SFF-8643 to SFF-8643 for backplane connections).
• 충분한 와트수를 가진 전원 공급 장치(PSU)tage and available power connectors.
• An operating system that supports large capacity drives (e.g., Windows Server, Linux, FreeBSD).

4.2. 물리적 설치

1. 준비 : Power down your system and disconnect the power cord. Open the computer case or server enclosure.
2. 드라이브 마운트: Secure the hard drive into an available 3.5-inch drive bay using appropriate mounting screws. Ensure the drive is firmly seated to minimize vibration.
3. 데이터 케이블을 연결하세요: Connect one end of the SAS data cable to the SAS port on the hard drive (SFF-8482 connector) and the other end to an available port on your SAS HBA or RAID controller.
4. 전원 케이블 연결: Connect a standard SATA power connector from your PSU to the power input on the hard drive.
5. Address PWDIS (Power Disable Feature) - Important Note: Some newer SAS drives, including certain Exos models, may incorporate the SATA 3.3 Power Disable (PWDIS) feature. If your system's backplane or power supply applies 3.3V to Pin 3 of the SATA power connector, the drive may not spin up.
   • 증상: Drive is not detected, or does not spin up.
   • 해결책: If experiencing this issue, you may need to use a power adapter cable that does not connect the 3.3V line to Pin 3, or physically isolate Pin 3 on the drive's power connector. Consult your system's documentation or search for "SATA 3.3 PWDIS" for detailed solutions. This is a common consideration for enterprise drives in certain older or non-compliant systems.
6. 폐쇄형 시스템: Once all connections are secure, close your computer case or server enclosure.

4.3. 드라이브 초기화

1. 전원 켜기: Reconnect the power cord and power on your system.
2. BIOS/UEFI 구성: Access your system's BIOS/UEFI settings or the SAS HBA/RAID controller's configuration utility to verify that the drive is detected.
3. 운영 체제 인식: Once the operating system loads, the drive should be recognized. For Windows, open Disk Management. For Linux, use commands like lsblk or fdisk -l.
4. 초기화 및 포맷: The drive will likely appear as "unallocated space." You will need to initialize the disk (GPT for drives larger than 2TB), create partitions, and format them with a suitable file system (e.g., NTFS, ext4, ZFS) before use. Refer to your operating system's documentation for detailed steps on disk initialization and formatting.
