Mass Storage

Please ensure that the disks are working properly and connected correctly and the power supply is sufficient. The following contains information about certain types of storage media.

SCSI/SAS

When using SCSI devices, please ensure that they are configured correctly and connected to one of the supported SCSI controllers.

Note: For SCSI and SAS disks, we recommend using the Windows or the Linux variant because they offer a wider spectrum of support for SCSI and SAS controllers than the Symobi variant.

In addition to the adapters listed under SCSI and SAS, the Symobi-Variant also supports other SCSI controllers, either as Onboard-Chipset (AIC), or as adapter (AHA, ASC). They are identifiable by the vendor ID and device ID, which are listed in the table below:

USB

USB devices can either be connected directly or over a USB hub. In order to achieve the highest transfer rates as possible, it is recommended that they be connected directly to the PC or the USB controller.

Note: USB 3 devices must be connected by a special USB 3 cable together with an appropriate USB connector (blue), and must be used, if applicable, with an external power supply in order to utilize the top speed of USB 3.

Thermal Issues

Some mass storage devices, especially very fast SSDs, can reach high data transfer rates, which may lead to overheating problems. This usually results in frequent read or write errors on the respective device, due to the chip installed therein becoming unresponsive to commands. This may also occur with hardware bridges, for example with SATA-to-USB adapters and it usually occurs in cheaper devices.

Note: This type of response represents a hardware error due to current standards, clearly stipulating that normal software commands cannot cause any damage to the hardware.

In order to prevent these types of issues, please use, if applicable, the program's speed limitation option. Depending on the setting, the process will then be slower than usual due to the program automatically adding small pauses to prevent the hardware from overheating.
