Technologies in HP ProLiant Gen8 c-Class server blades

12
Processor technologies
HP ProLiant Gen8 c-Class server blades use multi-core technologies from Intel and AMD (shown in Table 1). A multi-core
processor has two or more separate execution cores on one or more physical dies so that it can perform more work
within a given clock cycle. To take advantage of multi-core processing, software must be multi-threaded to distribute
the work across multiple execution cores.

Intel Xeon processors
We use Intel Xeon E5-2400, E5-2600, and E5-4600 series processors in the newly introduced 2 and 4-socket ProLiant
Gen8 c-Class server blades. These processors use hafnium-based, 32 nm Hi-k metal gate silicon technology. Xeon E5-
2600 series processors in the HP ProLiant Gen8 server blades have two, four, six, or eight cores and operate from 60 W
(lower power) to 135 W (high performance). These processors feature an integrated northbridge and memory controller.
The processors work with registered DIMMs (RDIMMs), unbuffered DIMMs (UDIMMs), low-voltage RDIMMs (LV RDIMMs),
and load-reduced DIMMs (LR-DIMMs). HP ProLiant Gen8 server blades based on Intel E5 processors use the Intel C600
Series Chipset with one of these E5 processors:
The ProLiant Gen8 BL420c provides up to two Intel Xeon E5-2400 processors, and delivers up to 1600 MHz speeds
with 12 DIMMs enabling up to 384 GB of HP SmartMemory
The ProLiant Gen8 BL460c provides up to two Intel Xeon E5-2600 processors with 2-, 4-, 6-, and 8-cores. The ES-
2600 handles 16 threads, delivering up to 33 percent higher performance

, with capabilities for up to 130 W
processors without system configuration restrictions
The ProLiant Gen8 BL660c provides up to four density-optimized Intel Xeon E5-4600 processors, each with up to eight
cores and 130 watts without system configuration restrictions
The ProLiant Gen8 server blades feature these Intel Xeon processor capabilities:
Processor Internal Sensors and Thermal Control - Protection against over-temperature conditions.
Cache parity/ECC - Protects cache data from accidental data corruption due to particle hits, etc.
Legacy Error Mode - Corrupt data is contained before it is consumed to ensure data corruption does not occur.
QPI Protocol Protection via Cycle Redundancy Check (CRC) - Automatically detects data errors using a checksum of
either 8 bits or 16 bits.
QPI Link Level Retry - Retransmits when a transient error is detected on the QPI link.
PCIe Advanced Error Reporting - Enhanced PCIe reporting features such as finer granularity in defining the error type,
ability to specify the severity of each uncorrectable error, error logging, ability to identify the source of an error, and
more.
Direct Media Interface link (DMI)- A x4 bi-directional chip-to-chip interconnect between the processor and chipset. The
DMI link provides 2.0 GB/s of bandwidth in each direction (Upstream and Downstream).
Processor internal sensors and thermal control - Protection against over-temperature conditions.
