Storage Subsystem; Power And Cooling - HP ProLiant DL560 Technology Brief

Enabler Kit, this read cache can be converted into a battery-backed, 64-MB write cache that is fully
transportable and provides 72-hour data protection. The Enabler Kit ships with ProLiant DL560 2P
models, but it is an option for 1P models.
External storage solutions require the addition of a PCI or PCI-X option card. IMB2 connects three I/O
expansion slots (none of which is hot pluggable):
• Two full-length 64-bit/100-MHz PCI-X slots, 3.3-volt
• One full-length 64-bit/133-MHz PCI-X slot, 3.3-volt
PCI-X technology provides a significant improvement in performance beyond that of conventional PCI
systems. The performance improvements are a result of two primary differences between conventional
PCI and PCI-X: higher clock frequencies—made possible by the register-to-register protocol—and
protocol enhancements such as the attribute phase and split transactions. For more information on
these performance improvements, read "PCI-X: An Evolution of the PCI Bus," document number
TC990903TB, available on the HP website at
ftp://ftp.compaq.com/pub/supportinformation/papers/tc990903tb.pdf.
The GC-LE chipset uses a thin IMB to connect the host bridge to the south bridge. The South Bridge
provides interfaces to the following I/O devices:
• Integrated Lights-Out (iLO) controller on the system board
• Integrated ATI Rage XL video controller with 8 MB of SDRAM video memory
• Integrated 1280 x 1024, 16M color on the PCI local bus
• Two USB ports
• Support for a slot-based Remote Insight Lights-Out Edition (RILOE) II controller

Storage subsystem

The ProLiant DL560 server ships standard without internal disk drives. The internal Wide Ultra3 SCSI
backplane supports an internal hot-plug Ultra3 drive cage with up to two 1-inch disk drives or one HP
StorageWorks internal AIT tape drive. The system supports up to 293.6 GB internal hot-plug drive
storage (2 x 146.8-GB one-inch Wide Ultra320 SCSI disk drives) with Redundant Array of
Inexpensive Disks (RAID) Level 0 or 1 protection across the internal disk drives.
The server is Ultra320 ready. Running at Ultra320 speeds will simply require the use of Wide
Ultra320 drives and installation of a Wide Ultra320 array controller when they become available.
The ProLiant DL560 server does not have an external SCSI port. Running external drives requires the
installation of a slot-based controller.
The storage subsystem includes a 1.44-MB slim line diskette drive and a slim line removable media
bay with a 24x IDE CD-ROM drive. The CD-ROM drive is ejectable for improved security and
serviceability. The system also supports one multibay that can be used for a CD, DVD, or a planned
CD read/write and DVD combination drive.

Power and cooling

HP developed the ProLiant DL560 server especially for customers looking to maximize the power and
cooling efficiency of their rack space while maintaining high levels of performance when running
back-office and enterprise business applications. HP engineers designed the system to support
anticipated processor speed and cache upgrades through the year 2004. The ProLiant DL560 server
uses low-wattage, ultra-efficient power supplies that can run fully configured using either low-line or
high-line power sources. The flexibility of low-line or high-line AC power enables customers to scale
capacity when planned and unplanned upgrades become necessary.
