Advanced Extension
Server Application Optimization (SAO) license improves overall application performance for physical
servers and virtual machines. SAO, when deployed with B-Series Fibre Channel HBAs, extends B-Series
Adaptive Networking from the B-series SAN fabric to the server infrastructure. This delivers application-
level, fine-grain Quality of Service (QoS) management to the HBAs and related server applications.
Solution Requirements:
SAO license must be installed on the edge (server connected) switch
Adaptive networking (AN) license must be installed on the edge (server connected) switch
SAO requires B-series HBA installed in the server
number of Fibre Channel ports from four to sixteen and the number of Gigabit Ethernet ports from two to
six. A 1606 Base Extension SAN Switch with the Upgrade License also supports up to eight FCIP tunnels
instead of two and supports advanced capabilities such as tape read/write pipelining.
Tape pipelining is similar to FastWrite in that it reduces the number of round-triptime delays that the
server must wait while writing to tape. In the case of Tape Pipelining, the FCIP ports act as a tape device (on
the server side) and as a server (on the tape device side). I/O requests are initiated and acknowledged
locally at both end of the link. The final Write Tape Mark command from the
server is acknowledged only after all data has been written to the tape device.
Optional software license for the 1606 Extension SAN Switch which enables two advanced extension
features: FCIP Trunking and Adaptive Rate Limiting.
FCIP Trunking:
FCIP Trunking feature allows multiple IP source and destination address pairs (defined as FCIP circuits) via
multiple of the 1 GE interfaces to provide high bandwidth FCIP tunnel and failover resiliency. In addition,
each FCIP circuit supports four QoS classes (Class-F, Hi, Medium and Low Priority), each as a TCP
connection.
Adaptive Rate Limiting:
An FCIP tunnel can be configured a minimum (guaranteed) committed rate as well as a maximum
committed rate. FCIP tunnel will run at least the minimum rate. If additional bandwidth is needed, the
committed rate will grow until the channel traffic demand is satisfied, maximum committed rate is
reached, or the throughput capabilities of the network are reached.
Adaptive Rate Limiting:
Adaptive Rate Limiting dynamically adjusts shared bandwidth between guaranteed minimum rates and
uncongested maximum rates for each FCIP circuit within a tunnel or trunk. This overcomes the problem of
fixed provisioning of bandwidth that leads to over-provisioning and underutilization of bandwidth.
Adaptive Rate Limiting enables applications to exceed guaranteed minimum rates when competing
bandwidth is idle.
