Datasheet
HP Memory Quarantine (based on Intel MCA Recovery technology). In conjunction with the
operating system support, allows a server to recover from uncorrectable memory errors which
would have otherwise caused a system crash.
Double Device Data Correction (DDDC). DDDC provides the ability to save a DIMM from being
replaced due to a bad dram device (BL620c G7 Intel Xeon E7-2800/8867L models).
Data Bus ECC protection for automatic correction from a single data bit error and detection of
double data error bits.
Advanced ECC/SDDC provides continued memory operation in the event of a single memory
device failure and allows removal of a single DRAM from the memory map if it exhibits a failure
and recovers its data into a new device.
Supports for both x4 and x8 Intel® SDDC.
Demand Scrubbing writes corrected data back to the memory once a correctable error is detected
on a read transaction.
DIMM Address/Control Bus Parity Protection provides a means to detect and protect command
and address errors.
Memory Failover uses a mirrored DIMM once a failed DIMM in a mirrored set is detected.
Memory Mirroring provides a copy of memory stored with dynamic failover in case of failure
within socket (intra-socket) memory mirroring.
The system will operate in non-hemisphere mode when mirroring is enabled.
Rank Sparring (On Line Spare) provides dynamic failover to a spare DIMM rank or spare rank pair
behind the same memory controller. Cannot be enabled concurrently with memory mirroring.
NOTE:
NOTE:NOTE:
NOTE:
HP offers the rank sparing rather than DIMM sparing as rank sparing uses less spare
memory resulting in less overhead.
Failed DIMM Isolation identifies a specific failing DIMM lockstep pair thereby enabling the user to
replace only the failed DIMM pair. Identifies a single DIMM for correctable errors and DIMM pair
for uncorrectable errors.
Virtualization

Virtualization
Intel® VT-x (FlexMigration, FlexPriority, and Extended Page Tables) provides:
Platform control between the VMM and guest OSs for faster, more reliable and secure
transfers.
VM migration features that enhance flexibility for failover, load balancing, disaster recovery,
and maintenance.
Intel® VT-x Real Mode & Pause Loop Exiting (BL620c G7 Intel Xeon E7-2800/8867L models):
Real Mode allows guests to operate in real mode, removing the performance overhead and
complexity of an emulator.
Pause Loop Exiting provides detection of spin locks in guest software and helps avoid lock-
holder preemption to reduce overhead and improve performance.
Intel® VT-d (Intel® Virtualization Technology for Directed I/O) enables the VMM to assign specific
I/O devices to specific guest OSs improving security and availability.

Optional dual-port Fibre Channel mezzanine cards for redundant SAN connections.
Optional dual-port InfiniBand mezzanine cards for redundant high performance connections.
Four embedded Ethernet adapter ports for redundant LAN connections.
Multiple mezzanine I/O expansion slots each supported multiple data paths routed to redundant
interconnect modules.
Network Adapter Teaming (Bonding) provides network fault tolerance, transmit load balancing,
and switch-assisted load balancing.
