HPE 817937-B21 DL380 Gen9 Xeon E5-2640v4 Processor Kit

Brand:

HPE

HPE 817937-B21 is an HPE ProLiant DL380 Gen9 processor kit featuring the Intel Xeon E5-2640 v4, a 10-core processor operating at 2.40 GHz with 25 MB cache and a 90W TDP. It is positioned within the DL380 Gen9 E5-2600 v4 processor family as a balanced option for virtualization, business applications, infrastructure services, and general-purpose enterprise workloads. The kit provides a defined OEM processor option for compatible DL380 Gen9 systems and is useful for processor replacement, standardization, or capacity upgrades.

OVERVIEW

HPE 817937-B21 is a 10-core Intel Xeon E5-2640 v4 processor kit for the HPE ProLiant DL380 Gen9, combining 2.40 GHz operating speed, 25 MB cache and a 90W thermal design power. Compatibility: HPE ProLiant DL380 Gen9. Model comparison: 817937-B21 is the standard processor kit; 817937-L21 is the factory-installed/FIO counterpart.

USE CASES

DL380 Gen9 processor replacement – Provides an exact HPE part-number option for replacing a compatible E5-2640 v4 processor.
Virtualization hosts – Ten physical cores provide useful compute capacity for supported virtual-machine workloads.
Business application servers – Suitable for general enterprise applications requiring balanced CPU performance and power consumption.
Database infrastructure – Provides 25 MB cache and 10-core processing for supported database workloads.
File and print services – Delivers practical server compute capacity for departmental infrastructure services.
Web and application hosting – Supports multi-threaded workloads where additional physical cores improve concurrent processing.
Development and test environments – Useful for maintaining consistent CPU configurations across DL380 Gen9 test servers.
Server refurbishment – Helps return compatible DL380 Gen9 systems to a documented processor configuration.
Enterprise spare inventory – Provides a clearly identifiable OEM processor SKU for maintenance planning.
Infrastructure standardization – Helps organizations maintain consistent E5-2640 v4 configurations across compatible DL380 Gen9 deployments.

KEY FEATURES

10-core Intel Xeon E5-2640 v4 – Provides 10 physical processing cores for parallel enterprise workloads.
2.40 GHz base frequency – Delivers a balanced operating speed for general-purpose server applications.
25 MB cache – Provides substantial on-chip cache capacity to support data-intensive processing.
90W TDP – Offers a moderate thermal design point for deployments where performance and power efficiency must be balanced.
Intel Xeon E5-2600 v4 family – Places the processor within Intel's enterprise-oriented Broadwell-EP server processor generation.
64-bit processing – Supports modern 64-bit server operating environments and applications.
Socket R3 / LGA2011-3 – Matches the documented processor socket used by the compatible DL380 Gen9 platform.
