- 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).
- Unit bekalan kuasa (PSU) dengan kuasa yang mencukupitage and available power connectors.
- An operating system that supports large capacity drives (e.g., Windows Server, Linux, FreeBSD).
4.2. Pemasangan Fizikal
- Sediakan: Power down your system and disconnect the power cord. Open the computer case or server enclosure.
- Lekapkan Pemacu: 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.
- Sambungkan Kabel Data: 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.
- Sambungkan Kabel Kuasa: Connect a standard SATA power connector from your PSU to the power input on the hard drive.
- 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.
- simptom: Drive is not detected, or does not spin up.
- Penyelesaian: 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.
- Tutup Sistem: Once all connections are secure, close your computer case or server enclosure.
4.3. Initializing the Drive
- Hidupkan kuasa: Reconnect the power cord and power on your system.
- Konfigurasi BIOS/UEFI: Access your system's BIOS/UEFI settings or the SAS HBA/RAID controller's configuration utility to verify that the drive is detected.
- Pengecaman Sistem Operasi: Once the operating system loads, the drive should be recognized. For Windows, open Disk Management. For Linux, use commands like
lsblkorfdisk -l. - Mulakan dan Format: 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.
