Host Buses Status
•
Host Bus MBytes/Sec—Average number of megabytes transferred over the host buses each
second
Host Buses Inventory
•
Bus Configuration—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—Operating speed of each bus
PCI bus
The following information is provided for a PCI bus.
PCI Bus Status
•
MBytes/Sec—Average number of megabytes transferred on the selected PCI bus each second.
•
PCI Utilization %—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 %.
NOTE: Insight Control performance management does not accurately report the negotiated PCI
bus protocol when unknown PCI devices with slower transfer rates than the controller are configured
on the same bus.
PCI Bus Inventory
•
PCI Support—Supported and negotiated PCI protocol (bus and speed)
•
PCI Devices—PCI bus slots and any I/O expansion boards installed in the slots
