Storage expansion
Four drive bays and one optional USB dual SD card adapter are available for storage expansion and support the following types of drives:
Bay 1 to 3 support the following:
3.5-inch hard-disk or solid-state drives
2.5-inch hard-disk or solid-state drives (in 3.5 to 2.5-inch drive bay adapter)
Bay 4 supports the following:
One half-height optical disk drive
One LTO/RDX tape drive
Note
Before installing the LTO tape drive, make sure to purchase the corresponding optional tape drive cable kit.
Make sure the power is on when executing remote access and power policy setup.
Ignore the warning message “Unrecoverable PS/2 or USB keyboard failure,” because the system does not support PS/2 devices.
Some Lenovo systems management applications, including XClarity Administrator, XClarity Controller, XClarity Energy Manager, and XClarity Essentials, are not supported by ST50.
RAID (depending on model)
The following options with RAID levels 0, 1, and 5 are available for this server. In addition, RAID level 10 is available when four drives are installed in the server.
