Viewing And Managing Storage I/O Quality Of Service - Qlogic Fibre Channel NPIV Storage Networking Guide Manual

NOTE:
Ensure that the host and the guest are not trying to use the pass-through
disk concurrently; Hyper-V requires that the disk be offline on the host.
Therefore, the pass-through storage must be offline in the Hyper-V host
server (parent partition) before the VM guest can be configured to access it
using the pass-through method.
Maintain one VM per LUN for I/O isolation.
The virtual adapter port masked to the VM LUN is also masked to the pass-
through storage LUN for that VM.
Viewing and Managing Storage I/O Quality of
Service
QLogic's SANsurfer
of service (QoS) for QLogic's 4/8Gb Fibre Channel adapters.
The SANsurfer application provides storage I/O measurements for both
input/output operations (IOPS) and for throughput (in bytes per second (Bps)).
When storage I/O is isolated using NPIV technology, the measurements are
reflective for each VM workload.
In addition, an NPIV-based deployment enables QoS management of the Fibre
Channel adapter's I/O traffic. QLogic's 4Gb and 8Gb Fibre Channel adapters
incorporate technology that allow the user to manipulate I/O traffic by assigning
either a priority level or bandwidth allocation to the I/O traffic on a per NPIV
basis.
The illustrations in this section are based on the configuration in
