Feature Details and Restrictions

Converged Shared Uplink Sets (SUS) contain both the FCoE network and non-FCoE networks

FCoE-capable SUS must always contain ports from a single VC module

Active/Active configuration for FCoE traffic is required from VC perspective

Server needs to use vSwitch, NIC teaming or bonding and multi-pathing for failover

For Multi Enclosure (ME) environments, all corresponding ports in the remote enclosures will be included in the same SUS. e.g. selecting enc0:bay1:X1 means bay1:X1 in all

remote enclosures is also included.

Active-Active Design, FIP Snooping, no QCN, no FCoE Stacking

Bandwidth Optimization


Min/Max Rate Limited Bandwidth ControlSimple for any virtualized environment

Improve bandwidth utilization & performance

Minimum guaranteed and capped (maximum) ingress bandwidth

Share unused bandwidth proportionally among FlexNICs and FlexHBAs

Ideal for bursty applications such as VM migration or Ethernet-based backup

Supported with VC Flex-10, Flex10/10D and FlexFabric modules

QoS Enhancements

Min/Max Bandwidth Allocation

Max = Maximum allocated bandwidth This is the max rate for a FlexNIC to transmit when

all other FlexNICs on the same port are idle

Min = Guaranteed allocated bandwidth

When other FlexNICs are transmitting, the unused bandwidth is re-allocated based on the ratio of the Min bandwidth setting

In case of congestion, the bandwidth is re-allocated based on the ratio of the Min bandwidth setting

Improve bandwidth utilization and on-demand performance

Max 10Gb

2Gb


Min/Max Bandwidth Ethernet Settings

Configured by Server AdminDefined by Network Admin

Set maximum speed. If undefined, MAX = MAX link speed,

e.g. 10Gb

Advanced Network Settings

Set preferred speed = MIN

Select Preferred port speed

Select Custom port speed

Network Admin defined MAX


Priority Queue QoS


Virtual Connect Priority Queue QoSInteroperate with QoS environments to improve reliability and utilization

Flexible options to ensure application performance!

Enforce mode now complements NIC side

Allocate bandwidth up to 8 traffic classes

VC queues frames to classes

VC scheduler prioritizes on egress and ingress

Supported on all Flex-10 and FlexFabric modules

PreserveCoS

Pass-thru without prioritizing

EnforceCoS

Reuse external CoSmarkings to prioritize and classify traffic

MapCoS

Remark layer 3 (DSCP/ToS) to layer 2 (CoS) on egress

802.1Q L2 Priority Classification based classes

2 fixed - best effort and lossless (FCoE) 2 predefined - real time and medium (not enabled) 4 user defined

Allocatebandwidth

Each class assigned bandwidth (%) for shaping


QoS Basic Terms

MarkingIndicator within packet header specifying how traffic should be handled Layer 2 marking: CoS (IEEE 802.1p)

Layer 3 marking: IP ToS or DiffServ (multiple RFCs)

Classification Recognize ingress traffic that should be prioritized

Assign an internal traffic class (internal forwarding priority)

Scheduling Map traffic classes to pre-defined queues

Assign outbound bandwidth based on the traffic class definitions.

Typically, high priority traffic gets greater percentage of the bandwidth than best effort or low priority traffic


VC Traffic with and without QoS

Traffic pre-4.01 or QoS pass-through

Without QoS configured, traffic flows on a first in first out (FIFO) basis

During congestion, the traffic at the tail of the queue is dropped as shown above for packet number #6

Traffic with QoS

With QoS configured, traffic flows according to resource allocation and priority

Packets may enter in one order but exit in a different order based on priority

During congestion, some packets may be dropped based on queue resource allocation


Other 4.01 Enhancements


SNMP Overhaul Old traps are deprecated in the VC MIBs

New traps added to provide more granular error reporting

A trap is sent for each VC managed element state change (domain, enclosure, module, port, network, fabric, server, or profile)

Each trap describes what changed and what caused the change

Improves correlation between traps and SIM events

Expanded support for LLDP MIB, Bridge MIB, QoS MIB, Interface MIB and LAG MIB

Improved Manageability

Network Admin receives detailed SNMP information


Multicast FilteringEnabling multicast without flooding for authorized applications

Admin configures authorized applications to a Multicast stream

Authorized applications (endpoints) subscribe to a multicast stream

Virtual Connect sends multicast streams to subscribed applications only

Attempts by Unauthorized Applications to subscribe to Multicast (not Authorized by Admin) stream are blocked

128 filters, 32 rules and 64 filter sets
