7.5 RAID system

The device supports two separate SSD mass storage devices that can be used together with the help of

RAID technology (RAID = redundant array of independent disks).

To use this function, two type M.2 2242 Key M SSD cards with a SATA interface are required.

NVMe cards with a PCIe interface cannot be used.

Supported options:

RAID level 0 striping: this RAID variant is recommended when a large data storage system with

•

high data access speeds is required. Since the data are not stored redundantly, this level is only

recommended if data loss will not result in serious consequences, e.g. because the data can be

recovered easily if a storage medium fails.

•

RAID level 1 mirroring: both mass storage devices redundantly store the same data in this case. If

a mass storage device fails, usually no data is lost and the defective mass storage device can easily

be replaced. The total storage size corresponds to the smallest of the individual storage devices

used.

The desired RAID level must be specified when placing the order.

Further information is available in section 10.4 Installing or removing SSD cards.

This optional function uses the resources provided by the operating system.

External WLAN antennas can be connected to the connectors (RP-SMA) on the front panel. The EXT

WLAN1 connector is used to connect the first antenna (MAIN) and EXT WLAN2 is used to connect the

second antenna (AUX). The device automatically uses the connection with the better signal.

Devices with WLAN also have Bluetooth. This function uses the resources provided by the operating

system.

EXT WLAN2 must be used as the connection.
