4.8.3Default SFP Placement

Default configurations do not include an SFP connector in every SFP port. You might want to add or rearrange SFPs, depending on the configuration mode (loop or point-to- point), the number of planned host connections, the necessary number of redundant connections to hosts, and the number of expansion units needed.

The supported SFP is a single-port, optical SFP transceiver for multimode (short wave) or single-mode (long wave) use. It is compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA, Sep. 2000), and 1x and 2x Fiber Channel. The optical connector used is the low-profile LC connector.

SFPs are field-replaceable units (FRUs) and can be ordered from Dot Hill. These SFPs have been selected and tested to provide the necessary reliability and performance. SFPs from other vendors are not supported.
