Configuring the storage devices

The system supports 2.5-inch storage devices. It accommodates slim-

line optical drives and depending on system model, can support up to

six 2.5-inch hot-plug SATA hard disk drives or eight hot-plug SAS hard

disk drives.

Caution! To maintain proper system cooling, filler panels must be

installed if a device is not replaced.

Removing and installing a hard disk drive

Note: Use only Acer-qualified SAS or SATA HDDs. To purchase a

SAS or SATA HDD, contact your local Acer representative.

Caution! To ensure proper airflow and server cooling, all drive

bays must contain either a carrier with a hard drive installed in it

or a hard disk carrier cover.

Determining drive status

Each HDD carrier features two status LED indicators to display the hard

drive status. If you are replacing a failed HDD, determine which drive

has failed by checking the drive status LED. For more information on

how to determine the drive status, refer to “Hot-plug HDD LED

indicators” on page 25.
