Table 16. IDSDM new features
New feature
Description
Support for RAID and
Data Integrity
When RAID is enabled, writes to IDSDM will perform write operation to both
SD cards simultaneously
Ensures data integrity during power loss conditions
Support for USB 3.0
(higher bandwidth)
If USB 3.0 is disabled, or an error on USB 3.0 is detected, IDSDM will revert to
USB 2.0
User-prioritized SD
slots
User-defined primary SD slot for IDSDM; if RAID is enabled, content of primary
SD card will be mirrored on secondary SD card
Bad Block
management
Prevents a single bad sector from causing an SD card to fail
No more BIOS halt
during rebuild
IDSDM does not require the BIOS to halt during POST and wait for the rebuild
to complete; rebuild happens in the background and is much faster as
compare than the previous generation
Enhanced support for
mismatched SD cards
Functionality of primary SD card is not compromised if the secondary SD card
has a different speed or lower storage
Mismatch check will only happen if the IDSDM is operating in RAID mode
Only secondary SD card will be placed in mismatch state; if the secondary
card does not match the speed or have lower storage capacity than the
primary card, the secondary card will be placed in the Mismatch state
Enhanced support for
write-protected SD
cards
Write-protected SD cards are treated as read-only; if at least one card is write-
protected and RAID is enabled, IDSDM will operate in the degraded RAID state,
and RAID will automatically be disabled if both cards are write-protected
Seamless SD card
assignments
IDSDM will bring secondary SD card online and will make it primary if for some
reason primary SD card fails
If RAID is enabled, there will be no compromise in functionality however,
system will notify user of degraded RAID status
Enriched error
reporting
New errors have been implemented to help root cause a failure.
Failures will be in iDRAC logs
Multiple failures can be now recorded and logged
Mass erase for
enhanced security
Mass erase options are provided in IDSDM; enabling this register will clean up
all the data preset on SD cards
UHS-1 SD card support
Next-generation support
Optical drive
The R630 supports one slim, internal DVD-ROM or DVD+RW optical drive option in the 8-drive
configuration only.
Tape drive
The R630 does not support internal tape drives and does supports external tape drives. See the
External storage section.
