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 or more 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 virtual machines (VMs) deployed. I/O bottlenecks and memory performance issues can be reduced by giving VMs direct access to hardware I/O devices, eliminating the overhead of embedded software switches and improving system performance (1)

With the ability to create multiple partitions--each supporting TCP/IP, FCoE or iSCSI--and take advantage of flexible bandwidth provisioning on our 10GbE converged network adapters(1)

Among enterprises currently implementing virtualization, business-critical applications are now beginning to come into the spotlight. Enterprises are most willing to virtualize Web, database and email applications. But more than one-third of them are planning to implement virtualization within the next year for business-critical applications such as HR, accounting and ERP, showing that they are becoming more used to the technology.

QoS16 04/10/2023QLogic Corporation

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 entities

The concept of QoS is employed in both network and storage technologies to apply to the distribution of adapter 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 parameters

Scenario:

Six Virtual Machines sharing two single Port CNA adapters

There are only two NIC Functions for all of the VMs to share

− No VM has a dedicated NIC Function

− Bandwidth is only available to the VMs on a first come first serve basis

− There is no guarantee of any portion of NIC bandwidth being available to any of the VMs

This configuration allows for any of the VMs to be starved of bandwidth.

A business can now guaranteed an appropriate portion of bandwidth to a VM to meet SLA’s and Response Time requirements.

19 04/10/2023QLogic Corporation

Putting it into Perspective

To add Tier 1 Applications like ERP, Databases, OLTP and more will require predictably and consistency.

Delivering demanding Response Time and Service Level Agreement commitments in rapidly evolving conditions will require more than a Faster Pipe.

Determining VM’s Performance Profile

Understanding Network bandwidth demand is dynamic in nature

VM’s Service Level Agreement will be dependent on Network Bandwidth

Business must be able to flexibility to dynamically shift network bandwidth to

The Minimum Bandwidth (Min) is 0% so there are no Guaranteed Bandwidth allocations, VM’s could be starved.

If A, B, C are not transferring D may use all the Bandwidth; it’s Max 100%., No wasted Bandwidth

If A, B, D are not transferring, C may use up to it’s Max which is 40% the Bandwidth, leaving 60% wasted.

If 4 does not use it’s bandwidth, the other NPAR Nic’s may use up to their Max, 30%, leaving 10% wasted.

Scenario 1: Backup Server, Practical Example

Scenario:This backup Server has two single Port QLE3200 IEA adapters, each with 4 NIC functions.

Two 10GE pipes that are fully dedicated to Ethernet Traffic.

Items to Consider:Backups usually occur at the same time, each pipe is

currently configured with a Guaranteed equal percentage of the bandwidth.

Should one or two NIC slow the others are Over Subscribed and can use the freed bandwidth.

Monitor the usage of the ports to tune and improve performance.

VMWare Says:

Issues with many 1GbE NIC’s per Server

In today’s virtualized datacenters networking is typically based on large numbers of 1GbE physical connections that are used to isolate different types of traffic flows and to provide sufficient bandwidth.

Large numbers of GbE network adapters have a number of shortcomings:

Limited bandwidth

Excessive complexity

Higher capital costs

Lower utilization

Moving to 10GE

While the use of a 10GE solution greatly simplifies the networking infrastructure there are a few challenges that still need to be addressed.

10GE eliminates 1Gb flow restrictions.

QLogic’s OverSubscription VM’s are now able to use as much as 10GbE.

Provides a means of optimizing the 10GbE network bandwidth by traffic flows.

QLogic’s Minimum Bandwidth ensures that latency-sensitive and critical traffic flows can access the bandwidth they need.
