摘要： A Small Computer System Interface (SCSI) transport for fabric backplane enterprise servers provides for local and remote communication of storage system information between storage sub-system elements of an ES system and other elements of an ES system via a storage interface. The transport includes encapsulation of information for communication via a reliable transport implemented in part across a cellifying switch fabric. The transport may optionally include communication via Ethernet frames over any of a local network or the Internet. Remote Direct Memory Access (RDMA) and Direct Data Placement (DDP) protocols are used to communicate the information (commands, responses, and data) between SCSI initiator and target end-points. A Fiber Channel Module (FCM) may be operated as a SCSI target providing a storage interface to any of a Processor Memory Module (PMM), a System Control Module (SCM), and an OffLoad Module (OLM) operated as a SCSI initiator.

摘要： Consistent with the present disclosure, a method and apparatus for providing a uniform spectral gain of an optical amplifier is provided. Namely, a “balancing” step is carried out in which an optical channel having the lowest power level input to an optical circuit, such as an dynamic gain equalizer (DGE), is assigned a zero “attenuation error” and is substantially un-attenuated by the DGE. The lowest power level optical signal does not require further attenuation and effectively serves as a reference power level, which the power levels of the remaining optical signals are set to. For example, remaining optical signals are assigned either positive or negative attenuation errors relative to the zero attenuation error based on optical signal input powers to the DGE and accumulated DGE attenuations over time. Those optical signals having a negative attenuation error are substantially unattenuated by the DGE, because such optical signals are adequately attenuated and do not require further attenuation. On the other hand, the DGE is controlled to attenuate those optical signals having positive attenuation errors to thereby flatten the output spectrum of the amplifier. In one example, interpolation techniques may be employed to control those portions of the DGE (e.g., attenuators or pixels) that do not receive a channel, such that adjacent pixels that receive channels may impart a desired amount of attenuation. In addition, further interpolation may be provided to appropriately control the DGE pixels, if the number of channels supplied to the DGE is different than the number of pixels of the DGE.
