Chart 3a shows the read throughput performance of 1, 2, 3 and 4 A6826A adapters installed in rx2600,
rx4640, rx7620, rx8620, and HP Integrity Superdome servers. The X-axis represents the number of ports. The Y-
axis represents the throughput performance in MB/s.
Chart 3a shows excellent read throughput performance with linear scaling for 4 A6826As installed in rx2600,
rx4640, rx7620, rx8620 and HP Integrity Superdome servers, reaching an aggregate throughput of 1523MB/s.
A6826A adapters installed in HP Integrity servers offer an excellent scalable SAN solution.
