Standard Features
Av ai lab ili ty • Compaq Advanced Memory Protection Technology – delivers unsurpassed memory protection and server
availability:
• Advanced ECC Memory
ECC protection provides the ability to detect and correct single bit memory errors while Advanced ECC
extends this coverage to include protection against multiple simultaneous errors on a DIMM. Advanced
ECC detects and corrects 4bit memory errors that occur within a single DRAM chip on a DIMM.
Advanced ECC algorithms work in combination with industry standard ECC DIMMS.
Advanced Memory Protection Configurations
• Online Spare Memory
Offers a higher level of memory protection than Advanced ECC alone. The system is configured with a
spare bank of memory. If the number of single-bit correctable errors on a bank exceeds the pre-defined
error threshold, the failing bank will fail over to the Online Spare bank without intervention or server
interruption. The failed memory can then be replaced at the user’s convenience during a scheduled
maintenance window.
• Single-Board Mirrored Memory
Single-board mirrored memory provides a higher level of availability than Advanced ECC and Online
Spare Memory because it protects against multi-bit errors. Single-board Mirrored Memory uses a single
memory board that is configured with a mirrored/redundant set of memory. The system writes to both
sets of memory, but reads from one. If a memory bank has a multi-bit error or full DIMM failure, the
system simply reads from the mirrored bank instead. This process occurs without intervention or server
interruption, and the failed DIMM can be replaced during a regularly scheduled shutdown.
Note: All Compaq Advanced Memory Protection modes are configured in the ROM-Based Setup Utility (RBSU)
and viewable through Compaq Insight Manager 7 (CIM 7) and the Integrated Management Log (IML).
• PCI-X Hot Plug Technology (Four 64bit/100MHz PCI-X hot plug slots available)
• One 600W Hot Plug Power Supply standard
