.
HP Smart Array controllers are integrated on ProLiant servers, and support a variety of RAID types
including RAID 1+0 and RAID 5. Developed and patented by HP, RAID 6 Advanced Data Guarding
(ADG) is further supported on Smart Array controllers. This technology creates two sets of parity
striped data across the disks to help enable the system can withstand multiple disk failures without
data loss. RAID ADG enables high levels of fault tolerance in a cost-effective manner.
It is advisable to separate operating system from the Cell Manager application and IDB by
configuring separate c:\ and d:\ partitions on different drives running in RAID1+0 mode. This
configuration provides mirroring and striping, redundancy, and performance improvement.
Network adapter teaming
Network adapter teaming is software-based technology used to increase a server’s network
availability and performance. Teaming enables the logical grouping of physical adapters in the same
server (regardless of whether they are embedded devices or Peripheral Component Interconnect (PCI)
adapters) into a virtual adapter. This virtual adapter is seen by the network and server-resident
network-aware applications as a single network connection.
Most HP ProLiant Storage Servers are equipped with the HP Network Configuration Utility (NCU). The
utility allows administrators to configure and monitor Ethernet network interface controller (NIC) teams
in a Windows-based operating system. These teams provide options for increasing fault tolerance and
throughput. The NCU is also used for configuring and monitoring individual network adapters.
Fault tolerance provides automatic redundancy. If the primary NIC fails, the secondary NIC takes
over. Load Balancing provides the ability to balance transmissions across NICs.
HP-UX, Itanium
The first choice for a Cell Manager server in a Data Protector cell on HP-UX 11i v2/v3 combining the
same/similar characteristics than a HP ProLiant server is a server from the HP Integrity server family
featuring Intel
®
Itanium
®
processor.
At the time this white paper was compiled a HP Integrity rx3600 server was providing all of the
necessary features providing enough computing power and high availability.
An optional stand-alone pedestal mount, field installation only, also exists.
The features in detail are:
• Intel
®
Itanium
®
Processors
• Advanced Memory Protection
• Redundant Cooling and Power
• RAID Technology
• Redundant Ethernet Connections
• Automatic de-configuration of memory and processors
• Service processor to monitor system status
• Integrated Lights-Out Technology
• HP Integrity Essentials
