16 GB DIMMs must be installed in slots numbered A1, A2, A3, A4, B1, B2, B3, and B4 and 8 GB DIMMs must be installed in slots
A5, A6, B5, and B6.
NOTE: If all 3 slots in the channel are populated with 128 GB LRDIMMS, the clock speed drops to 2133MHz.
Storage
The Dell PowerEdge R630 provides storage expandability that allows customer to adapt to their workload and operational
demands. With comprehensive storage options, the R630 offers various drive types, internal and external storage controllers,
and different chassis and backplanes for varied numbers of drives.
Features such as Express Flash PCIe solid-state drives provide vastly accelerated performance over previous technologies.
Dell Express Flash drives use PCIe lanes to connect directly to the processor and chipset and are easily accessible through a
hot-plug drive bay.
All hard drives connect to the system board by using the hard drive backplane. Hard drives are supplied in hot-swappable
hard-drive carriers that fit in the hard-drive slots.
CAUTION:
Before attempting to remove or install a hard drive while the system is running, see the
documentation for the storage controller card. Ensure the host adapter is configured correctly to support
hot-swap hard drive removal and insertion.
CAUTION: Do not turn off or reboot your system while the hard drive is being formatted. Doing so can cause a
hard drive failure.
NOTE: Use only hard drives that have been tested and approved for use with the hard-drive backplane.
When you format a hard drive, allow enough time for the formatting to be completed. Be aware that high-capacity hard drives
can take a number of hours to format.
Backplane
The Dell PowerEdge R630 is available in several hot- plug, hard- drive chassis options, as detailed in the table below.
NOTE: The chassis option must be selected during purchase and cannot be changed or upgraded later.
