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: NOTE:
NOTE: Hot Plug Mirrored Memory and Dual-Board Online Spare Memory require the use
of two memory cards. All HP ProLiant 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 HP Systems Insight Manager 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 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)
