Installing And Removing Memory Boards - Intel SR6850HW4 - Server Platform - 0 MB RAM Product Manual

Installing and Removing Memory Boards

Memory boards can be configured in a redundant or a non-redundant configuration. memory boards
configured using RAID or mirroring are in a redundant configuration. If a memory board that is
configured in a redundant configuration has a memory DIMM or a memory board fault, the
memory board and / or DIMM containing the fault can be removed and replaced while the system
is powered on.
Memory boards that are configured in a non-redundant configuration (including memory boards
configured with spare memory) must not be removed while the system is powered on.
The following hot plug memory options are available.
Memory Hot Replace: While the system is in operation and configured with a RAID or
Mirroring configuration, you can replace a failed memory board. The replacement board must
include an identical memory capacity. The system will test, initialize, and rebuild the data on
the memory board and then include this board in the system memory configuration. The
activity is transparent to the operating system,
Memory Hot Add: While the system is in operation and configured with a RAID or Mirroring
configuration, you can increase the memory capacity of the system while the operating system
is active. For RAID remove and add memory to one memory board at a time. Replace the
removed memory board before adding memory to another board. For Mirroring, add two
additional memory boards. If your server is configured in the Maximum Compatibility
configuration, a new memory board can be added to an empty slot. When the initialization is
complete, the operating system is informed of the new memory.
CAUTION
Do not attempt to hot remove or hot add a memory board in a non-redundant
configuration. If your server is not configured in the BIOS setup utility for
Maximum Compatibility, Memory RAID, or Memory Mirroring, you must
power down your server before removing or installing any memory board or
memory DIMMs. For instructions, see
