Buffer Empty Ratio This field has no effect on the drive. Maximum Burst Size This field indicates the maximum amount of data that the target transfers during a data phase before disconnecting if the initiator has granted the disconnect privilege. This value is expressed in increments of 512 bytes (e.g. a value of one means 512 bytes, two means 1024 bytes, etc.). A value of zero indicates there is no limit on the amount of data transferred per connection. 2-36 Chapter 2
