Instruction Manual

Network Storage Enclosure Inventory
• Enclosure Configuration—Displays the type or model, name, and serial number of the network storage
enclosure.
• Controllers—Displays the name and model of the enclosure and whether it is operating with redundant
controllers.
• If a redundant controller is configured, then both standby and active controllers are listed.
• If redundancy is not configured, only active controllers are listed.
• Detected Servers—Displays a list of servers sharing the enclosure.
Host buses
The following information is provided for host buses.
Host Buses Status
▲ Host Bus MBytes/Sec—The average number of megabytes transferred over the host buses each second
Host Buses Inventory
• Bus Configuration—Displays a summary of each PCI or PCI-X bus on the server with the PCI/PCI-X slots
and the I/O expansion boards installed in each slot
• Operating speed—Displays the operating speed
PCI bus
The following information is provided for a PCI bus.
PCI Bus Status
• MBytes/Sec—The average number of megabytes transferred on the selected PCI bus each second.
• PCI Utilization %—The PCI utilization for the selected PCI bus. A 32-bit PCI and 64-bit PCI can operate
simultaneously on the same PCI bus. The utilization is primarily dependent on the MBytes/Sec rate and
the negotiated PCI bus protocol:
• 32-bit PCI—Operates at 33 MHz, resulting in a maximum throughput of 132 MB/s
• 64-bit PCI—Operates at 33 MHz, resulting in a maximum throughput of 264 MB/s
• 64-bit/50-MHz PCI-X—Provides a maximum throughput of 400 MB/s
• 64-bit/66-MHz PCI or PCI-X—Provides a maximum throughput of 528 MB/s
• 64-bit/100-MHz PCI-X—Provides a maximum throughput of 800 MB/s
• 64-bit/133-MHz PCI-X—Provides a maximum throughput of 1064 MB/s
• PCI Express X1—Provides a maximum throughput of 500 MB/s
• PCI Express X2—Provides a maximum throughput of 1000 MB/s
• PCI Express X4—Provides a maximum throughput of 2 GB/s
• PCI Express X8—Provides a maximum throughput of 4 GB/s
• PCI Express X12—Provides a maximum throughput of 6 GB/s
• PCI Express X16—Provides a maximum throughput of 8 GB/s
PCI bus performance is evaluated using the Bus Utilization %.
