3 CONFIGURATION

3.1 CONFIGURATION PREREQUISITES

3.1.1 SATA HOST CONNECTIONS

This guide assumes that you have already attached the EliteRAID ER104UT(-B) to a host computer that has been

installed with the R622 HBA (Host Bridge Adapter) or another SATA HBA with Port Multiplier (PM) support.

If you use a host controller that does not provide Port Multiplier support (Such as Intel ICH):

• The CLEAN MODE storage policy is unavailable when configuring the EliteRAID ER104UT(-B). Only one disk is

available on the host computer.

• Virtual volumes that you create in the Advanced Configuration Wizard must use at least 8 gigabytes (GB) of

available system capacity.

3.1.2 USB HOST CONNECTIONS

If you are connecting your EliteRAID ER104UT(-B) using a USB connection to your host, the USB port should be

compliant with USB 1.0, 2.0 and USB 3.0 or connected to a USB hub.

3.2 CHANGING HOST CONNECTIONS

The EliteRAID ER104UT(-B) supports both USB and eSATA host connections, although only one connection can be attached

at any given time. For the best data transfer performance, you should always use the eSATA host connection.

If it becomes necessary to change the host connection between eSATA and USB, the host computer system and the

EliteRAID ER104UT(-B) should both be powered down prior to making the host connection change to avoid any potential

data loss or corruption. After changing the host connection, all items can be powered-up to resume operation with the

new host connection.

3.3 DISCONNECTING A USB DEVICE

USB 2.0 external devices provide support for “plug & play” connection, so that your USB storage device can be connected

and disconnected while the computer is running. To prevent data loss or other failures, you must follow these steps when

disconnecting your USB 3.0 storage device from your host computer system. Once the physical USB device is disconnected,

any volumes that are associated with that device will become unavailable. On O/S (Opration Systems), the EliteRAID

ER104UT(-B) must be stopped from O/S before any devices can be disconnected.
