memory speed (that is, the speed at which the memory is actually running) depends
on several factors including:
• CPU capability
• DIMM speed
Actual memory speed will be the lowest of the two.
The HS23 supports memory mirroring. Chipkill is supported in Independent mode
when x4-based DIMMs are installed.
Additional features
• The BladeCenter HS23 system board contains 16 DIMM connectors (30 mm
blade).
– Chipkill is supported in Independent mode when x4-based DIMMs are installed.
• One or two hot-swap SATA or SAS devices are supported in the base blade.
• One Emulex BladeEngine 3 (BE3) controller with Dual 10Gb + Dual 1Gb Ethernet
is provided and can be upgraded with Features On Demand to FCoE and iSCSI
Hardware Offload.
BladeCenter HS23 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 HS23 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 HS23 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, designed 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, memory, and processors 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
