1-This model uses a qualied FC SFP option within the CNC ports (used for host connection). When in FC mode, the SFPs must be a
qualied 16Gb ber-optic option. A 16Gb/s SFP can run at 16Gb/s, 8Gb/s, 4Gb/s, or auto-negotiate its link speed.
2-This model uses a qualied 10GbE iSCSI option within the controller module CNC ports (used for host connection).
3-CNC ports support same-type or mixed-type SFPs in combination.
4-This model uses SFF-8644 connectors and qualied cable options for host connection.
5-This model supports 10Gb/s or 1Gb/s speeds (used for iSCSI host connection).
2U enclosures can be congured as single-IOM (with an IOM-blank), or dual-IOM.
