Input/Output; Table 1 Valid Cti Cache Sizes - HP 9000 V2500 SCA Operator's Manual

Table 1
Overview
V-Class Server Architecture
With small CTI cache sizes, additional aliasing between memory
locations may occur, reducing the cache hit rate and increasing the
latency for remote accesses. The bold entries in Table 1 show the
minimal CTI cache sizes needed to avoid excessive aliasing.

CTI cache memory is configured at system boot time. The CTI cache
memory is dedicated only to be used for encaching remote accesses, and
is not available for any other use, such as use by HP-UX or applications.

Input/Output

A multiple-cabinet V2500/V2600 server can contain up to 112 PCI I/O
cards, with each cabinet containing up to 28 PCI I/O cards. Each V2500/
V2600 cabinet includes 64-bit PCI chassis, eight PCI buses, and
connections for either three or four PCI cards per PCI bus.
The following I/O cards are supported on HP V2500/V2600 servers:
• Tachyon Fibre Channel
• HVD FWD SCSI
• LVD Ultra2 SCSI
• 10/100 Base T Ethernet
• 1000 Base SX Gigabit Ethernet
• FDDI
