  15. 15. The Business Need for VMFlex, NPAR and QoS"ESG research indicates that just over 30 percent of server virtualization users cited that they will soon have 25 ormore VMs per physical host, dramatically increasing I/O traffic," said Bob Laliberte, senior analyst for ESG. (1)If not properly managed, I/O can negatively impact application performance and limit the number of virtualmachines (VMs) deployed. I/O bottlenecks and memory performance issues can be reduced by giving VMsdirect access to hardware I/O devices, eliminating the overhead of embedded software switches and improvingsystem performance (1)With the ability to create multiple partitions--each supporting TCP/IP, FCoE or iSCSI--and take advantage offlexible bandwidth provisioning on our 10GbE converged network adapters(1)Among enterprises currently implementing virtualization, business-critical applications are now beginning to come intothe spotlight. Enterprises are most willing to virtualize Web, database and email applications. But more thanone-third of them are planning to implement virtualization within the next year for business-critical applicationssuch as HR, accounting and ERP, showing that they are becoming more used to the technology.

  17. 17. What Does Quality of Service Mean?Basically, Quality of Service (QoS) is The ability to control and enforce the distribution of finite resources among different entitiesThe concept of QoS is employed in both network and storage technologies to apply to the distribution ofadapter port bandwidth access among Virtual Machines NPAR QoS: A technology that distributes NIC bandwidth among VMs or applications through NPAR NIC Functions according to configured parameters ETS - Enhanced Transmission Selection: Allocates Bandwidth on DCB-enabled Ethernet ETS is Configured at the Switch• NPIV QoS: A technology that distributes SAN bandwidth among VMs attached to storage through Fibre Channel or FCoE, according to configured parameters• SR-IOV QoS: A technology that distributes NIC bandwidth among VMs or applications through SR-IOV NIC PFs and VFs, according to configured parameters17 QLogic Corporation 3/5/2012
