Performance and Recommended Use of AB290A Combination 2-Port U320 SCSI / 2-Port Gigabit Ethernet Cards

Recommended Use Based on Performance and Design
4
•
Schedule workloads for ports: All 4 ports can be cabled and connected. Schedule or
prioritize applications so that 2 ports are running full traffic at any given time or all 4
ports are running traffic at reduced rates. The 2 ports selected can be both ports of a
single technology or 1 port from each of the 2 technologies on the card. This provides
the best possible per port data rates.
• Set up a pair of cards for high availability as shown in Figure 2. On the first card,
configure one technology’s pair of ports as primary or active. On the second card,
configure the same technology’s pair of ports as alternate or hot standby. This is
another alternative to the scheduling technique summarized in the previous bullet. This
setup would provide the best performance and high availability. Achieving a similar
level of high availability would require using twice the number of 2-port single function
cards.
Figure 2 Setting Up a Pair of Cards for High Availability
The recommendations mentioned here were followed to achieve the results shown in this
article. Card throughput will be affected with configurations other than those recommended.
Besides providing exceptional performance, the AB290A provides increased connectivity
compared to other single technology networking or I/O cards. Please contact an HP
representative for additional help in understanding how to best deploy the AB290A
multi-function card.
