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.
RAID – Redundant Array
of Independent Disks
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.
