in the following paragraphs.

is 3
—Point-to-Point, Otherwise Loop. For the QLA23xx adapter, the default

■ Data Rate. This setting determines the QLA23xx adapter data rate. When this
setting is 2 Gb, the QLA23xx adapter runs at 2 Gbps. When this setting is Auto,
SANblade Manager determines what rate your system can accommodate and
sets the rate accordingly. The default is 1 Gb (the QLA23xx adapter runs at
1 Gbps). This setting does not apply to the QLA22xx adapter.

QLA2xxx adapter. For the QLA22xx adapter, the default size is 1024. If using
F-Port (point-to-point) connections, change this setting to 2048 for maximum
performance.
