•
The management module interfaces with each blade server for single systems management
control.
LS21 for BladeCenter blade servers deliver on reliability and serviceability.
Features include:
•
ECC DIMMs, combined with an integrated ECC memory controller, designed to help correct
many soft and hard single-bit memory errors, while minimizing disruption of service to LAN
clients
•
Chipkill memory, designed to correct up to four bits per DIMM to help keep your blade server
up and running
•
Memory hardware scrubbing, designed to help correct many soft memory errors automatically
without software intervention
•
ECC L2 cache processors to help improve data reliability and reduce downtime
•
CPU failure recovery in SMP configurations:
– Automatically reboots server
– Generates alerts
•
Predictive Failure Analysis® (PFA) on memory and processors to help alert the system
administrator of an imminent component failure
•
Dual Gigabit Ethernet connections that support:
– Failover, adapter fault tolerance
– PXE 2.0 Boot Agent
– Wake on LAN®
– Load balancing or teaming
•
An integrated management processor that supports diagnostic, reset, POST, and auto
recovery functions and monitors temperature and voltage; alerts generated when thresholds
are exceeded (refer to the Limitations section for restrictions)
High density using the 8677 BladeCenter Chassis: Up to 14 blade servers can be installed in
a new BladeCenter chassis. They can also be installed in an existing BladeCenter chassis at full
density after an upgrade with the 2,000-watt power supply option.
Power considerations: The 8677 BladeCenter Chassis with 1,200-, 1,400-, or 1,800-watt power
supply does not provide enough power to maintain redundancy at full density. Clients with the
8677-1XX and 2XX chassis who want full density must upgrade to the 2,000-watt power
supplies.
When using the BladeCenter H (model 8852) there are no current power limitations on the
