Страница: 20 / 110

Both Cell/B.E. processors and Cell/B.E. companion chips are underneath the heat
sinks and therefore not visible. The Cell/B.E. processors and the system XDR
memory are soldered onto the system board and are not removable.
Reliability, availability, and serviceability features
Three important features in server design are reliability, availability, and
serviceability (RAS). These RAS features are designed to help ensure that your
blade server is available when you want to use it; and, in the event of a failure, help
you easily diagnose and repair the failure with minimal inconvenience.
The following is a list of some of the RAS features that your blade server supports:
v Transparent CPU Hardware error recovery
v
ECC for XDR and DDR2 memory
v
PFA for CEs on the Cell/B.E. companion chip attached I/O Buffer DDR2 DIMMs
v
Memory Scrubbing on XDR system memory
v
XDR System memory failure isolation for memory errors to a single memory
interface (Cell/B.E.-0 or Cell/B.E.-1 attached)
v
DDR2 I/O Buffer memory failure isolation to a single DIMM
v
PCI Bus Parity
Blade level features include:
v Degraded boot for both XDR and DDR2 memory errors. XDR memory errors
may create holes in the memory map.
v
Automatic server recovery and restart:
– Automatic reboot after boot hangs (with switch of the boot flash to the backup
image)
– Automatic reboot after checkstop (without switch of the boot flash side)
v
Environmental monitors and alerts
v System VPD and VPD on all major electronic components
v
Lightbox LEDs
v System Management Services (SMS) menu support
v
Checkstop detection with data logging and automated reboot
