The SAS-HDX is a 2RU external disk storage containing up to 24 hot-swappable
SAS disks, with a minimum of 5 disks. External storage can be used with or
without internal storage.
It is connected to the XT2+ server via a dedicated SAS cable on the rear panel of
the server, provided that the X-ESAS connection module has been placed inside
the server.
Necessary equipment:
• XT2+ with SAS-HDX connector on the rear panel.
• Multicam version 10.03 or later
• SAS-HDX external disk storage

Note on Disk LEDs Activity
When starting from a clean disk array (after a “Clear Video Disks” from
the EVS maintenance menu), the XT2+ server is recording first on RAID
#0 until this one is full, then on RAID #1 and finally on RAID #2. It is
therefore normal to see activity only on some disks depending on how
much material (clips and record trains) is stored on the server.
