Qnap SATA Expansion

TL-D400S
High-performance desktop SATA 6Gbps JBOD storage enclosure
TL-D400S JBOD storage enclosure allows you to back up and expand your QNAP NAS, Windows and Ubuntu computers and servers. The TL-D400S features four 3.5-inch SATA 6Gb/s drive bays and comes with a QXP PCIe card for connecting the enclosure using a SFF-8088 (or SFF-8644) cable. It provides reliable read/write performance for smooth storage and backup tasks.
1. QNAP recommends following the standard procedure for connecting or disconnecting the TL-D400S. For more information, please see the TL-D400S user manual.
2. The TL-D400S can only be used as an individual storage pool or volume on the NAS. Its storage pool or volume cannot be combined into the connected NAS. NAS applications cannot be installed on the TL-D400S.
3. The TL-D400S only supports QNAP NAS running on QTS 4.4.2 (or above) or QuTS hero operating system.
4. When the TL-D400S is connected to a Windows system, if JBOD disk slots are empty, virtual disks will be created in the empty slots due to the firmware mechanism of the control chip.
5. When the TL-D400S is connected to a Windows system, JBOD Manager will poll the first detected physical disk / virtual disk for monitoring the JBOD health status (physical disks take priority for monitoring).
6. Non-Server versions of Windows have a 63TB limit for a single volume. Thus, when connecting QNAP storage expansion products, the same limitation applies. For volumes larger than 63TB, it is recommended to use the Windows Server operating system.
