Intel AS/400 RISC Server - Manual (Page 66)

Notes:
1.
Unshielded Twisted Pair (UTP) card; uses copper wire cabling
2. Uses fiber optics
3. Custom Card Identification Number and System i Feature Code
4. Virtual Ethernet enables you to establish communication via TCP/IP between logical partitions and can be used without
any additional hardware or software.
5. Depends on the hardware of the system.
6. These are theoretical hardware unidirectional speeds
7. Each port can handle 1000 Mbps
8. Blade communicates with the VIOS Partition via Virtual Ethernet
9. Host Ethernet Adapter for IBM Power 550, 9409-M50 running IBM i Operating System

5.2 Communication Performance Test Environment
Hardware
All PCI-X measurements for 100 Mbps and 1 Gigabit were completed on an IBM System i 570+ 8-Way
(2.2 GHz). Each system is configured as an LPAR, and each communication test was performed between
two partitions on the same system with one dedicated CPU. The gigabit IOAs were installed in a
133MHz PCI-X slot.
The measurements for 10 Gigabit were completed on two IBM System i 520+ 2-Way (1.9 GHz) servers.
Each System i server is configured as a single LPAR system with one dedicated CPU. Each
communication test was performed between the two systems and the 10 Gigabit IOAs were installed in
the 266 MHz PCI-X DDR(double data rate) slot for maximum performance. Only the 10 Gigabit Short
Reach (573A) IOA’s were used in our test environment.
All PCI-e measurements were completed on an IBM System i 9406-MMA 7061 16 way or IBM Power
550, 9409-M50. Each system is configured as an LPAR, and each communication test was performed
between two partitions on the same system with one dedicated CPU. The Gigabit IOA's where installed in
a PCI-e 8x slot.
All Blade Center measurements where collected on a 4 processor 7998-61X Blade in a Blade Center
H chassis, 32 GB of memory . The AIX partition running the VIOS server was not limited. All
performance data was collect with the Blade running as the server. The System i partition (on the Blade)
was limited to 1 CPU with 4 GB of memory and communicated with an external IBM System i 570+
8-Way (2.2 GHz) configured as a single LPAR system with one dedicated CPU and 4 GB of Memory.
Software
The NetPerf and Netop workloads are primitive-level function workloads used to explore
communications performance. Workloads consist of programs that run between a System i client and a
System i server, Multiple instances of the workloads can be executed over multiple connections to
increase the system load. The programs communicate with each other using sockets or SSL APIs.
