QoS Menu (Command Line Option -qos)
SN0054614-00 K 3-101
Enter Hex Pattern (xx) :
Type two hex digits. The system creates the new virtual port, for example:
(Create Virtual Port Menu)
Enter Selection: 2
Enter Hex Pattern <xx>: EF
The system returns the following:
Virtual Port 21-EF-00-8B-14-5A-CF created successfully on HBA
instance 4.
Note that the entered hex digits, EF, now appear in byte 1 of the new virtual port
WWPN.
To see the change to the virtual ports, you must manually refresh the
configuration.
QoS Menu
(Command Line Option -qos)
15: QoS
QoS (quality of service) refers to service level agreement (SLA) to ensure
business continuity when transmitting data over virtual ports by either setting
priorities or allocating bandwidth. SANsurfer FC/CNA HBA CLI provides an
easy-to-use interface that lets you assign QoS to virtual ports by either setting
priorities or allocating bandwidth to them:
Setting the QoS by bandwidth lets you allocate up to 80% of the number
of gigabits per second (Gbps) transmission speed of the physical port's
capacity to its defined virtual ports (NPIV). Using this feature lets you
guarantee a transmission rate for each virtual port that requires a specific
bandwidth to run mission-critical applications for business continuity using
virtual ports. The setting for a given QoS can resolve bottlenecks that exist
when virtual machines contend for port bandwidth.
NOTE:
The QoS Menu option is available only for Windows operating systems and
8Gb and 10Gb adapters. For Windows Server 2008, QoS is supported only
with MSI-X enabled.
