HP Advanced Error Containment
The DL580 Gen8 features advanced PCIe error containment capability that prevents corrupted data
propagation. If data corruption is found on the PCIe bus, the system re-sets the PCIe root port and re-
starts the transaction. This feature helps protect customer data and prevents the error from creating a
chain of failures across the datacenter.
NOTE:
Supported on Intel® E7-4800/8800 based systems only
HP Advanced Fault Resiliency
Double Data Device Correction (DDDC)
- Detects and corrects up to two DRAM chip failures for every
x4 DIMM in the server. DDDC requires memory lockstep mode and may impact performance to
varying degrees depending on workload memory access characteristics.
NOTE:
Supported on Intel® E7-4800/8800 based systems only.
Single Data Device Correction (SDDC)
- Detects and corrects one DRAM chip failures for every x4
DIMM in the server. Further corrects single-bit errors after one DRAM chip failure. SDDC is supported
in performance mode and does not impact system performance.
NOTE:
Supported on Intel® E7-4800/8800 based systems only.
Online Memory Sparing
- Tracks excessive number of correctable errors and copies the contents of
an unhealthy rank to an available spare rank in advance of multi-bit or persistent single-bit failures
that may result in future uncorrectable faults. Since a DIMM or a rank is needed to perform sparing,
this technique reduces the total amount of available memory by the amount of memory used for
sparing.
Memory Mirroring
- System maintains two copies of all data. If an uncorrectable memory error
occurs, the system automatically retrieves the good data from the mirrored (redundant) copy.
Memory Mirroring consumes 50% of the system memory capacity.
NOTE:
Memory mirroring will be supported in a system firmware update post initial launch.
Redundant Interconnects and Failover
- The DL580 Gen8 system and Intel® Xeon® E7-4800/8800 v2
processors combine to provide a high degree of fault tolerance and failover capabilities for key
processor-processor or memory-processor links or clocks.
Hot-plug redundant power supplies and fans
- The DL580 Gen8 server features N+N redundant
power supplies and N+1 redundant fans to keep your system running in the unlikely case a power
supply or fan malfunctions.
