Actual memory speed will be the lowest of the two.
The HS23E supports memory mirroring. Chipkill is supported in Independent mode
when x4-based DIMMs are installed.
Additional features
• The BladeCenter HS23E system board contains 12 DIMM connectors (30 mm
blade).
– Chipkill is supported in Independent mode when x4-based DIMMs are installed.
• One or two hot-swap SATA hard drives are supported in the base blade. One or
two SAS hard drives, SATA hard drives or solid-state drives are supported with
CIOv RAID card.
• One Broadcom BCM5718 10/100/1000BASE-T Ethernet LAN controller
BladeCenter HS23E blade servers are designed for high throughput from processor
to memory, and to bus I/O.
These features, combined with Symmetric Multi-Processing (SMP) capability and
blade-thin density, make the HS23E an excellent choice for space- and power-
constrained environments used for:
• Infrastructure applications
• Virtualization
• General enterprise applications
High-availability and serviceability features
• Hot-swap blades enable easy access to each blade server.
• The management module interfaces with each blade server for single systems
management control.
The BladeCenter HS23E blade servers deliver reliability and serviceability.
Features include:
• High-performance ECC memory, combined with an integrated ECC memory
controller, to help correct soft and hard single-bit memory errors, while reducing
disruption of service to LAN clients.
• Chipkill memory correction for up to four bits per DIMM to help keep your blade
server up and running.
• Memory hardware scrubbing, to correct many soft memory errors automatically
without software intervention.
• ECC L2 cache processors to help improve data reliability and reduce downtime.
• PFA on SAS HDD options and memory to help alert the system administrator of
imminent component failures.
• Support for Ethernet connections
– Failover, adapter fault tolerance
– PXE 2.0 Boot Agent
– Wake on LAN
– Load balancing or teaming
• Integrated management processor that supports diagnostic, reset, POST, and
auto-recovery functions, and monitors temperature and voltage. Alerts are
generated when certain thresholds are exceeded (refer to the Limitations section
for restrictions).
Optional add-ons (available for an additional charge)
• Active Energy Manager (AEM) is positioned as a key component of the energy-
efficient technologies and services of IBM , which are part of the IBM Project
Green initiative that began May 2007. AEM measures, monitors, and manages
