Why NPAR?
•
Lowers TCO
•
•
•
•
•
•
Efficient I/O Utilization
•
•
•
•
•
•
Consolidates cables, infrastructure, and I/O
Saves server resources
Reduces operational complexity
Flexible SAN and LAN personality
VM to VM NIC traffic without external switch
Allows dynamic bandwidth provisioning
Minimizes bandwidth waste
Scales I/O workloads and connections
Scale-Out performance for virtualized servers
Provides finer control for SLA / on demand services
Maximize Data Center Efficiency
Simpler Deployment
• Solution not dependent on OS or switch
• Configuration at pre-boot or OS level

October, 2011
Key Attributes
•
No OS or BIOS changes required
•
NIC controls transmit flow rate
•
User configurable
•
Dynamic bandwidth allocation
•
Storage and NIC personalities (function type)
•
Full offload for iSCSI and FCoE with NPAR
•
Concurrent FCoE, iSCSI and NIC support
•
Minimum bandwidth allows fine grain QoS

NPAR Configuration Bandwidth Allocation
•
Minimum Bandwidth
•
•
•
•
Minimum guaranteed bandwidth
Specified as % of link speed
Total of all partitions is up to Max bandwidth link
May exceed specified Min value up to Max value
• If excess bandwidth available on the physical port
•
Maximum Bandwidth
• Up to the Max allowed bandwidth
• Specified as % of link speed
• Not allowed to exceed Max value
• Even if excess bandwidth available on physical port
