HP ProLiant DL585 Server Technology - Technology Brief

NIC teaming support
The NC7782 supports two types of teaming: Network Fault Tolerance (NFT) teaming and
Load Balancing teaming.
NFT teaming increases system availability by providing failover between a primary and a
secondary network port on a server. It also monitors the server connection to the network
and automatically switches traffic to a redundant link in the event of a failure. In a system
configured for failover, a secondary port can take over for a failed primary port with no
interruption of server operations.
Load balancing teaming, sometimes called port-bonding or trunking, enhances server
availability and performance by sharing traffic among multiple network adapters. Load
balancing capability allows optimum throughput by “bonding” multiple ports in a server to
act as a single port. Load balancing teaming increases network bandwidth and
redundancy.
High availability technologies
The ProLiant DL585 server supports dual, hot-pluggable, redundant power supplies to
ensure uninterrupted service. All models ship standard with dual 870-Watt Hot-Plug
Redundant Power Supplies (featuring hi/lo line auto-sensing).
The ProLiant DL585 supports internal hot-plug drives and has a transportable Battery-
Backed Write Cache (BBWC) Enabler module with battery charge of up to 72 hours. This
BBWC module protects up to 64 MB of write cache memory from hard boot, power, SCSI
controller, or system board failures. In the event of a failure, write cache data can be
moved to another ProLiant DL585 server in the data center by simply removing the BBWC
Enabler and 5i Plus Memory Module simultaneously.
CAUTION
To prevent data loss, the cable between the BBWC
Enabler and 5i Plus Memory Module must NOT be
disconnected.
The ProLiant DL585 has eight hot-pluggable fans. The 7+1 redundant fan configuration
provides a single cooling zone across the major server subsystems for7x24 cooling.
Storage technologies
The ProLiant DL585 server supports internal hot-plug storage and has an empty Wide
Ultra3/Ultra320 drive cage. An internal Wide Ultra3/Ultra 320 backplane supports up to four
1-inch Ultra320 SCSI hot-plug drives and is configurable to support simplex (4x1) or duplex
(2x2) mode. Duplex is the default mode. The server supports serial attached SCSI (SAS),
small form factor (SFF) drives within the 8-Bay SAS/SATA Cage Option Kit. The SAS/SATA
Cage must be used in conjunction with a SAS/SATA Controller such as the Smart Array P600
Controller to upgrade all U320 models to SAS. The server supports up to 1.20 TB of internal
storage using 4 x 300 GB Ultra320 SCSI 1-inch hard drives or up to 582 GB of internal storage
using 8 x 72.8 GB SAS SFF drives. The server supports Ultra320 drives with the addition of a
PCI-X or PCI option card cabled to the backplane. An external SCSI port is not available on
the ProLiant DL585 server. External SCSI solutions require the addition of a PCI or PCI-X
option card with an external connector.
A dual-channel, Ultra3 Smart Array 5i Plus Controller is integrated on the DL585 system board.
This controller supports RAID 0, 1, 1+0, and 5 across the internal hard disk drives. The DL585
supports a BBWC Enabler module on the Smart Array 5i Plus Controller with 64 MB of total
