For LTO drive an additional SAS controller must be installed because
onboard SAS is no more supported.
●
16*2.5-inch SAS/SATA hard disk drives connected to SAS RAID controller:
up to sixteen HDD modules, each with a 2.5-inch SAS/SATA hard disk drive
with a maximum height of 1 inch. One 5.25-inch bay for an optional LTO or
RDX drive.
To support 16 HDDs you need either the new SAS expander board or a
second RAID controller.
●
24*2.5-inch SAS/SATA hard disk drives connected to SAS RAID controller:
up to twenty-four HDD modules, each with a 2.5-inch SAS/SATA hard disk
drive with a maximum height of 1 inch. The option of ODD, LTO or RDX drive
is not available.
To support 24 HDDs you need the new SAS expander board.
The HDD modules are connected to the SAS/SATA backplane without cables.
This allows HDD modules to be simply plugged in or pulled out (for further
details see the "FUJITSU Server PRIMERGY RX2540 M1 Server Upgrade and
Maintenance Manual").
If the server has a RAID configuration, the HDD modules can be exchanged
during operation (hot-swap).
Onboard SATA controller
One SATA controller is integrated on the system board; up to four SATA hard
disk drives can be connected to the controller. The LSI Embedded MegaRAID
software (Software RAID) supports RAID levels 0, 1 and 10.
For more information on configuring the controller, see section "Configuring the
onboard SATA controller" on page 77.
