Hard Disk
Hard disks store log and report data. Different models support different types of hard disk modules.
Hard Disk Overview
Hard disks fall into two types, namely, hard disk unit and combination.
Hard Disk Unit
- The hard disk unit SM-HDD-SAS300G-A consists of the 2.5-inch SAS300G hard disk and hard disk tray.
- The hard disk unit SM-HDD-SAS600G-A consists of the 2.5-inch SAS600G hard disk and hard disk tray.
- The hard disk unit SM-HDD-SAS1200G-A consists of the 2.5-inch SAS1200G hard disk and hard disk tray.
The hard disk unit provides the following functions:
- Stores log and report data.
- Works with another hard disk unit to form a RAID1 for reliable service data backup. Once the working hard disk fails, the system automatically reads data from the mirror hard disk, ensuring non-stop services.
- Supports hot swap. If a hard disk fails, you can replace it without powering off the USG. After the replacement, you can restore data from the mirror hard disk.
Hard Disk Combination
- The hard disk combination SM-HDD-SAS300G-B consists of the hard disk card and hard disk unit SM-HDD-SAS300G-A.
- The hard disk combination SM-HDD-SAS600G-B consists of the hard disk card and hard disk unit SM-HDD-SAS600G-A.
- The hard disk combination SM-HDD-SAS1200G-B consists of the hard disk card and hard disk unit SM-HDD-SAS1200G-A.
The hard disk combination provides the following functions:
- Stores log and report data.
- Hard disk unit is hot-swappable, but the hard disk card is not.
Hard Disk Unit SM-HDD-SAS300G-A
The hard disk unit SM-HDD-SAS300G-A consists of the 2.5-inch SAS300G hard disk and hard disk tray.
- Hard disk unit SM-HDD-SAS300G-A cannot be directly installed on the USG6306, USG6308, USG6330, USG6350, USG6360, USG6370, USG6380, USG6390, USG6390E, USG6507, USG6530, USG6550, USG6570, USG6620, USG6630 and needs to be used together with a hard disk card.
- Do not low-level format the hard disk. Otherwise, the hard disk cannot be used.
