5.4 Checking Operation after Installation and Preparing the HDD for Use

Notes:

1.The user can arbitrarily specify the following parameters according to the system requirements:

ARRE

AWRE

TB

PER

2.The user also can arbitrarily specify parameters other than the above. However, it is recommended to use the default setting in normal operations.

(2)Disconnection/reconnection parameters (page code = 2)

The following parameters are used to optimize the start timing of reconnection processing to transfer data on the loop at a read (READ or READ EXTENDED command) or write operation (WRITE, WRITE EXTENDED, or WRITE AND VERIFY command) of the disk. Refer to Chapter 3 “Data Buffer Management” of the Fibre Channel Interface Specifications for further details.

Parameter

 

Default value

• Buffer full ratio

 

00 (HEX)

• Buffer empty ratio

 

00 (HEX)

Notes:

1.In a system without the disconnection function, these parameters need not be specified.

2.Determine the parameter values in consideration of the following performance factors of the system:

Time required for reconnection processing

Average amount of processing data specified with a command

Refer to Chapter 3 “Data Buffer Management” of the Fibre Channel Interface Specifications for how to obtain the rough calculation values for the parameter values to be set. It is recommended to evaluate the validity of the specified values by measuring performance in an operation status under the average system load requirements.
