  • Page 34: Direct N_Port Attachment

    Direct N_Port Attachment ■ Direct N_Port Attachment The T10000 tape drives support direct attachment to a host through a host bus adapter (HBA) that creates an N-Port. The HBA sends and receives to and from the tape drive. ■ Addressing StorageTek tape drives use: Port name, Node name, and Port ID for login validation.

  • Page 35: Terms And Definitions

    Terms and Definitions ■ Terms and Definitions Tables throughout this chapter use the following terms for compliance with the American National Standards Institute (ANSI) Fibre Channel Tape (FC–Tape) Technical Report for the StorageTek implementation. FC–Tape Terms Allowed (A) Can be used between an initiator and a target (tape drive). For tape drives, this is typically dependent on the particular feature or parameter and its applicability to the request from an initiator.

  • Page 36: Loop Initialization Features

    Loop Initialization Features ■ Loop Initialization Features Arbitrated loop initialization protocol assigns up to a possible 126 addresses to different ports on the loop and builds a map of these addresses. The following pages describe some loop initialization features StorageTek tape drives perform.

  • Page 37: Selective Reset

    Loop Initialization Features Selective Reset Selective resets perform a reset on the receiving port. These resets are helpful for error recovery or reconfiguration of the loop. Any NL_Port that uses a selective reset transmits a LIP(AL_PD,AL_PS). • AL_PD field contains the address of the port being reset •...

  • Page 38: Loop Initialization Hard Assigned

    Loop Initialization Features Loop Initialization Hard Assigned StorageTek tape drives support the process of Loop Initialization Hard Assigned (LIHA) addresses. This process is supported when the tape drive is first powered on and a configuration parameter enables it. Loop Initialization Soft Assigned StorageTek tape drives support the process of Loop Initialization Soft Assigned (LISA) addresses.

  • Page 39: Public Loop Initialization Completion

    Loop Initialization Features Public Loop Initialization Completion The public loop tape device has now acquired a loop address of “00 00 xx” at this point in initialization, where xx is its assigned AL_PA. Next the tape drive will attempt a Fabric Login (FLOGI) with the loop FL_Port. If the login is not successful, the tape drive will revert back to private loop operation, see the Private Loop Initialization Completion description.

  • Page 40: Tape Drive States

    Loop Initialization Features Tape Drive States Power Up When the drive completes the power-on process both of the FC ports will be enabled and will attempt to initialize on the attached FC topology.

  • Page 60: Disparity

    Error Detection and Management Disparity Fibre Channel uses a scheme along with the 8B/10B encoding to protect transmission characters and aid in error detection called running disparity. Running disparity adds a second dimension to the transmission of characters. This dimension provides a balance of ones and zeros which helps protect transmission characters and controls the heat output of the transmitter.

  • Page 61: Fibre Channel Timers

    Fibre Channel Timers ■ Fibre Channel Timers StorageTek’s tape drives use the timer values in Table Table 24. Timer Summary Timer Value Implemented By Initiator Target StorageTek AL_TIME 15 ms R_T_TOV 100 ms E_D_TOV Private = 2 sec. Public = supplied + 2 sec. R_A_TOV Private = 0 sec.

  • Page 62: Error_Detect Timeout

    Fibre Channel Timers Error_Detect Timeout The Error Detect Timeout value (E_D_TOV) is the maximum time permitted for a Sequence Initiator between the transmission of consecutive data frames within a single sequence. This is also the minimum time that a Sequence Recipient waits for the reception of the next frame within a single sequence before recognizing a Sequence timeout.
