16 Operating Manual RX2520 M4
HDDs/SSDs - 2.5-inch
The server is available in the following drive configurations:
● 8x 2.5-inch version:
– Up to eight SATA HDDs connected to SATA 1-4 and SATA 7-10 onboard.
One 5.25-inch bay for an optional ODD and/or LTO or RDX drive.
– Up to eight SAS HDDs connected to SAS RAID controller. One 5.25-inch
bay for an optional ODD and/or LTO or RDX drive.
For LTO drive an additional SAS controller must be installed because
onboard SAS is no more supported.
● 16x 2.5-inch SAS/SATA HDDs connected to SAS RAID controller:
up to sixteen HDD modules, each with a 2.5-inch SAS/SATA HDD 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.
● 24x 2.5-inch SAS/SATA HDDs connected to SAS RAID controller:
up to twenty-four HDD modules, each with a 2.5-inch SAS/SATA HDD 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 RX2520 M4 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
A SATA controller is integrated on the system board; up to eight SATA HDDs
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 80.
