The unstoppable combination of high-availability features and renowned Compaq reliability assure
. .
maximum uptime for data centers, HPTC, or e-commerce implementations. The ProLiant
. .
. .
DL590/64 server delivers the best combination of high-availability features offered in any
. .
four-processor-capable, rack-optimized server.
. .
. .
. . The ProLiant DL590/64 offers such leading and robust high-availability features as Advanced
. .
ECC memory technology, proven PCI Hot Plug capabilities, truly redundant hot-plug system fans,
. .
. . hot-plug hard drives, hot-plug redundant power supplies, and an integrated Smart Array controller
. .
that provides embedded RAID functionality. Like all ProLiant servers, the ProLiant DL590/64
. .
server undergoes thousands of hours of quality assurance, integration, optimization and testing for
. .
. .
maximum reliability.

PCI Hot Plug Technology

. .
. .
The ProLiant DL590/64 server incorporates industry-standard PCI Hot Plug technology. This
. .
. .
technology, pioneered by Compaq, adds hot-plug capabilities to existing PCI adapters for
. .
increased system availability and serviceability. Compaq led the industry by licensing its PCI Hot
. .
. .
Plug implementation, thus broadening customer access to this industry-standard technology.
. .
. .
Compaq's implementation of PCI Hot Plug incorporates electronics into the server to control each
. .
. .
PCI Hot Plug slot individually: a single slot can be powered down without affecting the operation
. .
of the others slots. Use of a hardware notification instead of a software notification ensures
. .
. .
removal of the correct adapter card. PCI Hot Plug technology allows the following capabilities
. .
while the system is running:
. .
. .
•
Hot replacement – replacing a single PCI adapter with a similar adapter
. .
. .
•
. .
Hot upgrade – replacing a PCI adapter with an upgraded adapter
. .
. .
•
Hot expansion – adding a PCI adapter to an empty slot
. .
. .
. .
Redundant Network Interface Controller Technology
. .
. .
Redundant network interface controller (NIC) technology allows two similar NICs to share a
. .
. .
single instance of device driver code. One NIC becomes the active network controller and the
. .
other NIC acts as a standby controller. If the active NIC fails, the network traffic is automatically
. .
. .
switched to the standby NIC. This redundancy eliminates the NIC or network cable as a single
. .
point of failure. With PCI Hot Plug technology, the failed NIC can be replaced without rebooting
. .
. .
the server. Thus, the end user can have continuous service and the administrator can greatly
. .
reduce planned and unplanned downtime.
. .
. .
. . The ProLiant DL590/64 server supports a Compaq NC3134 Fast Ethernet controller on the PCI
. .
local bus. The NC3134 is a dual port, 10/100 modular NIC that features 64-bit, 66-MHz
. .
. . performance using Intel's latest networking silicon, the 82559 application-specific integrated
. .
circuit. The faster clock speed of the 66-MHz NIC delivers better performance than 33-MHz NICs
. .
because it moves data off the PCI bus faster, thereby freeing the bus for further use.
. .
. .
. .
The NC3134 ships with advanced server features such as support for network fault tolerance. The
. .
NIC's dual ports allow customers to configure the NC3134. The modular design of the NC3134
. .
. .
enables user to upgrade to two additional 10/100 ports, to a 100-Mbps fiber port, or to Gigabit
. .
Ethernet SX or LX.
