Table 3 details the comparison of the 6600-48G/48G-4XG switches, the 2910al-48G, and the 3500yl-48G
switches in more detail .

Note: The 6600-48G-4XG switch does not support 1-Gb mGBIC/SFP capability. The last four ports are exclusively for 10-Gb SFP+ transceivers; they are
not capable of running at Gigabit speeds.
Table 3: 6600-48G/48G-4XG switches vs. 2910al-48G and 3500yl-48G switches
With line-rate processing across all four 10-Gb SFP+ ports, the 6600-48G-4XG switch is an effective solution to
provide true non-blocking connectivity to 40-Gb servers with 40-Gb uplink capability (along with the increased
packet-buffer capabilities of the 6600 series for its 10-Gb ports—18 MB of packet buffering, in this case, per
pair of 10-Gb ports for 36-MB total in available 10-Gb memory . A similarly configured 3500yl-48G switch
with its 4 x 10-Gb yl module option would be oversubscribed if connected to 40-Gb servers with only 28 .8-Gb
maximum throughput . The 3500yl-48G switch is also limited to 4 .5 MB of packet buffer memory across all
10-Gb ports) .
