DA-11372 World Wide — Version 25 — March 20, 2003
Standard Advanced ECC functionality detects and corrects single bit and specific multi-bit memory errors
(4bit and 8bit) while using industry standard registered DIMMS. Functionality is embedded in the chipset
design.
HP Advanced Memory Protection Technology – delivers unsurpassed memory protection and server
availability:
Online Spare Memory
Offers a higher level of memory protection than Advanced ECC alone. If the number of single-bit
correctable errors on a bank exceeds the pre-defined error threshold, that bank will fail over to the
online spare bank without intervention or server interruption. Online spare memory can be configured
across one or two memory cards. 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
mirrored banks on a single memory board that is configured with one redundant bank of memory. The
system writes to both banks, but reads from one. If a DIMM(s) has a multi-bit error, 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.
Hot Plug Mirrored Memory
Hot Plug Mirrored Memory is a fault-tolerant memory feature that provides a higher level of availability
than Advanced ECC, Online Spare Memory, or Single-Board Mirrored Memory because it protects
against multi-bit errors and does not require any server downtime to replace failed DIMMs. Hot Plug
Mirrored Memory requires that two memory boards be installed, one an exact mirror of the other, which
run in parallel and provide protection against multi-bit memory errors. When configured for Hot Plug
Mirrored Memory, the system writes to both memory boards, but reads from one. If a read error
occurs, the system fails over to the redundant memory board. At that point the memory board
containing the failed DIMMs can be hot replaced. Once the failed DIMMs are replaced and the
memory board re-installed into the server, the system goes back to full mirrored status. All this occurs
without bringing the server down.
NOTE: Hot Plug Mirrored Memory and Dual-Board Online Spare Memory require the use of two
memory cards. All DL580 G2 servers ship standard with a single memory board. The second memory
board is optional (P/N 203320-B21).
NOTE: All HP Advanced Memory Protection modes are user configurable through the ROM-Based
Setup Utility (RBSU) and viewable through Insight Manager 7 and the Integrated Management Log
(IML.).
PCI-X Hot Plug Technology (Four 64bit/100-MHz PCI-X hot plug slots available)
Smart Array 5i Plus Controller with standard Battery Backed Write Cache (BBWC) Enabler provides
transportable data protection and increases overall controller performance. Up to 64MB Battery Backed
Write Cache protection available on 2P DL580 G2 models (BBWC Enabler is optional on 1P model.)
Redundant Cooling Zones across major server subsystems (Memory, I/O, CPU) provide 7x24 cooling. Each
zone is independent of each other and is able to support n 1 redundancy, as indicated below:
PCI-X expansion zone is 1 1 redundant (fans 1 and 2)
Memory zone is 1 1 redundant (fans 3 and 4)
CPU zone is 2 1 redundant (fans 5, 6, and 7)
This zone configuration enables the server to withstand up to three fan failures, provided that they are not
within the same zone. Each fan is hot plug redundant and individually removable.
Up to four Hot Plug Ultra3 Drive Bays
Duplex or Simplex SCSI Backplane (Duplex configuration is standard)
Dual Hot Plug Redundant Power Supplies (standard on 2P Models, one ships standard on 1P Models.)
