Memory Mirroring Feature
Memory mirroring is a new
Memory mirroring allows the server to continue operation if a DIMM error is encountered.
With memory mirroring, one degraded memory group is automatically disengaged and the operation is switched to the other memory group. This brings the reliability of the system to memory uncorrectable error without any service interruption and without compromising system availability.
To enabling memory mirroring feature, it is necessary to install the DIMMs in group #1 for a normal operation and to install the DIMMs in group #3 for standby.
In this case, it doesn't allow the system to install DIMMs in group #2.
Online Sparing Memory Feature
Online spare memory is a new
Online spare memory allows the server to continue operation if a DIMM begin to fail. When a pre- defined threshold for the maximum number of correctable ECC errors has been exceeded, online spare memory initializes the bank in standby (spare bank) and takes over the failing memory bank.
The memory bank that exceeds the error threshold can be replaced at the customer's convenience during a scheduled shut down.
With online spare memory, degraded memory is automatically disengaged and a fresh set of memory is used in its place. This brings the reliability of the system to the
To enable online sparing memory feature, it is necessary to install the DIMMs in group #1 or in group #1 and group #2 for a normal operation and to install the DIMMs in group #3 for standby.
