Page 19: Configuring An Extended Fabric Connection
Configuring an Extended Fabric Connection The Extended Fabric feature achieves long distance connections by allocating more frame buffers for Fibre Channel traffic. Long distance connections require more frame buffers than regular ISL connections. The greater the distance level of a ISL long distance connection, the more frame buffers are required. This affects the amount of buffers left over in the quad. -
Page 20: Long Distance Configuration
Configuring an Extended Fabric Connection Long Distance Configuration Note: Only active GBICs should be used when using HP Extended Fabric. Note: Trunking is not supported with LE, L1, and L2 modes.
