socketed on a 2x5 header attached to the AT8050 PCB. Here are the main features:
•Many available sizes
•Mean-Time Between Failures (MTBF) of 5 millions hours
•5 Years Useful Life under specific conditions
•Read throughput of 28MB/second
•Write throughput of 20MB/second
•I/O Operations per second of 100 (4KB random 2 Read + 1 Write)
•5V operating voltage
•0 to 70 Celsius operating temperature
2.5 Serial ATA/Serial Attached SCSI
2.5.1 Serial Attached SCSI (LSISAS1064e is PCI-e rev 1.1)
This option is only available through a combination of the RTM8050 and AT8050, on which the controller
resides. Two SAS ports are routed from the RTM8050 to the AMC Bay (more details in the AMC Mezzanine
section below).
The RTM8050 features a SAS controller (the LSISAS1064e is PCI-e rev 1.1) which interfaces with the AT8050
by a dedicated PCI Express connection or through the Update Channel Interface such as the Kontron carrier
AMC AT8402. If the RTM controller is used, a SAS or SATA hard drive can be located in the AT8050 AMC bay or
in the RTM8050 Hard Disk tray, but thermal restrictions on the type of supported hard drives applies
(standard 15mm SAS drives with 60 Celsius maximum Tcase are not supported over specified operating

Note:
During the installation of an OS on a HDD, the USB Flash Module must be deactivated. If the USB
Flash Module remains active, the Master Boot Record will be installed on it by default. This can not
be avoided and will cause the OS to be unable to boot when booting from the HDD.
