3.4.3 EXTERNAL RAID ARRAY FOR XS SERVERS
Two types of external RAID array can be used according to the model of internal
disks which equip the XS server:
• XT-HDX array for SCSI disks
• SAS-HDX for SAS disks.
XT-HDX EXTERNAL RAID ARRAY
The XT-HDX is an external disk storage containing up to 15 SCSI disks. It is
connected to the XS server via a dedicated SCSI cable on the backplane of the
server.
Necessary equipment
• XS with XT-HDX connector on the back plane and MT5D_LNK board
• XT-HDX external disk storage
Important
An XS server cannot work simultaneously with an internal RAID array
(MT5D) and an external RAID array (XT-HDX). When an XS server is
equipped with the XT-HDX external disk storage, the MT5D internal
RAID is replaced by the MT5D_LNK board. This replacement has to be
done by EVS staff.
Installation and operation
1. Both the XS server and the XT-HDX need to be switched off.
2. The XT-HDX expansion chassis must be located immediately above the chassis
of the XS server.
3. Connect the XT-HDX to the server only with the external SCSI cable provided
by EVS (see schema and picture)
4. Disks in the XT-HDX rack are hot-swappable. However, a disk can only be
extracted from the rack when it has been stopped by the software application
(disk led blinking slowly red with a 4-second cycle)
