Status of QNAP TS-21x/TS-22x support
QNAP TS-21x/TS-22x devices are based on a Marvell Kirkwood System on a Chip. Marvell has done a lot of work to get support for the Kirkwood platform into the mainline kernel. However, some features of the Kirkwood platform are not as well supported in the mainline kernel (which we use in Debian) as in the original Marvell LSP (Linux Support Package) used by QNAP. Please take this into account before deciding whether you want to install Debian, especially if you have specific requirements (e.g. related to performance).
The table below shows how well different components of the QNAP TS-21x/TS-22x are supported by Debian:
| Component | Comment |
|---|---|
| Debian | Debian and the Debian installer work well |
| CPU | Supported in the kernel |
| SATA | Supported in the kernel by the sata_mv module |
| Ethernet | Supported in the kernel by the mv643xx module |
| USB | Supported |
| RTC | Supported in the kernel by the rtc-s35390a module |
| LEDs | Supported in qcontrol |
| Fan | Supported in qcontrol |
| Beeper | Supported in qcontrol |
| XOR engine | Supported. Support is mainly helpful for RAID5 at the moment, so it's not quite useful on the TS-21x |
| Crypto engine | Basic support |
| Wake-on-LAN (WOL) | Supported in qcontrol. |
| Scheduled power | Supported; see instructions |
