Best Practices in Hyper-V
No hardware resource is more important to overall performance than memory. Plan to ensure each VM has the memory it needs, but without wasting memory in the process.
Memory
Start with Planning
When planning a Hyper-V installation, it is important to take into account the new capabilities of Hyper-V in Windows Server 2012. Windows Server 2012 has added significantly to the scalability of Hyper-V. For datacenters virtualizing Tier-1 applications, the critical scalability enhancement is the ability to have up to 1TB of memory and 64 virtual CPU cores per VM. This will ensure almost all Tier-1 applications should perform well in a Microsoft Hyper-V environment.
However, these new capabilities bring new complexities, and with them the need to plan new datacenter architectures. This not only includes planning the deployment for today’s needs, but also thoroughly investigating evolution strategies for applications before bolting down racks and filling them with servers.
 Planning which applications are going to run on your virtualized servers is the first step in understanding your needs.
 From there, it is critical to define server integration points with existing resources (likely core switching and storage resources), and how these will be affected by the evolution of existing resources.
 After that, planning your approach to Live Migration and capacity growth over the lifetime of your new infrastructure will help you scope internal I/O requirements appropriately.
Finally, determining whether to utilize converged networks or not, and what I/O performance you need, will enable you to intelligently discuss your I/O and networking options with your SAN/LAN equipment providers. These steps will help you ensure success when virtualizing your Tier-1 applications.
To fully optimize virtualized data centers, servers need maximum I/O capacity to support high input output operation rates and high bandwidth applications. Increased bandwidth is also needed for server virtualization, which aggregates I/O from multiple virtual machines (VMs) to the host’s data path. This next- generation combination takes full advantage of new features that are described in detail in this planning guide. Read on to discover how QLogic can increase your infrastructure ROI and overall competitiveness.

The Great VM Migration
With many server admins working on their 3rd and 4th generation of virtualized servers, the focus has changed from interoperability and learning the behavior of Hyper-V, to increasing VM density (#VMs/Physical Host Server). With the availability of servers based on Intel’s E5 processors (multi-core, 768GB of RAM, PCI Express Gen3) and the combination of new features within Hyper-V, a new, game-changing compute platform was introduced. This new platform allows for new levels of VM density and for the first time Tier-1 applications that previously required dedicated server hardware can now run on virtual servers, achieving improved performance, scalability and efficiency.
While Hyper-V and E5-based servers are seeing significant deployments in many enterprise datacenters, the I/O and network infrastructure to support these new technologies lags far behind. In a survey conducted by IT Brand Pulse, IT professionals said the average number of VMs per server would almost double in the next 24 months. Approximately 25% of IT professionals surveyed also said what they need most to increase the VM density is more I/O bandwidth. The purpose of this industry brief is to provide a planning guide to help enterprises deploy Tier-1 applications with adequate bandwidth in a dense Microsoft Hyper-V Server 2012 virtualization environment.

Windows Server 2012 Hyper-V
The newest release of Windows Server 2012 Hyper-V delivers a high-performance VM chassis harnessing the new I/O capabilities of 16Gb Fibre Channel (FC) Storage Networking and 10GbE Data Networking. Several new features of Windows Server 2012 Hyper-V are highlighted below:
 vCPU—Virtual machines can now have up to 64 virtual CPUs (vCPUs) and 1TB of virtual RAM (vRAM) allowing Tier- 1 application to be virtualized and new levels of VM density to be reached.
 Virtual Fibre Channel (Virtual FC)—Hyper-V now enables VM workloads to access FC SANs by provisioning virtual FC ports with a standard Worldwide Name (WWN) within the guest OS.
 Live Migration—Virtual FC also enables Live Migration of VMs across Hyper-V hosts while maintaining FC connectivity. Two WWNs are configured and maintained for each virtual FC adapter.
 Live Storage Migration—A VM’s Virtual Hard Disk (VHDX) storage can now be migrated without shutting down the VM. The operation copies data from source storage device to a target via a FC or similar interconnect.
 Multipath I/O (MPIO)— Hyper-V now extends MPIO capability to VMs ensuring fault-tolerant FC connectivity for delivering High Availability and Resiliency to virtualized workloads
 16Gb Fibre Channel—To help maximize efficiency of Live Migration and Storage Motion, Hyper-V includes support for 16Gb Fibre Channel, the fastest storage interconnect available today.
 10GbE and SR-IOV— Allows 10GbE NIC to appear as multiple virtual devices that can optimize I/O performance by providing direct I/O for individual virtual machines.
From a storage planning perspective, when comparing Windows Server 2012 to previous version, there are two specifications which stand-out: the amount of memory/VM (1TB), and the amount of active VMs per machine (1,024).
Using today’s storage usage, a petabyte of storage could be needed to support 1024 VMs. While this scenario is unlikely for at least a few years, running 100 VMs with 512GB of virtual memory each on a single server (which would require 52TB of storage for the memory contents alone) is very foreseeable.
The ability to provide high-performance storage is critical for a high-density or Tier-1 virtualization strategy. The new storage tools in Hyper-V that we will cover later in this paper (virtual Fibre Channel, offloaded data transfer, and the new virtual hard disk format) can positively impact performance in these environments.

Picking the Right I/O Pieces, and Making Them Work Together
Tier-1 applications are uniquely demanding in many dimensions. Their needs with respect to CPU power, memory footprint, high availability/failover, resiliency and responsiveness to outside stimuli is typically unmatched within the enterprise. Moreover, Tier-1 applications also tend to be tightly integrated with other applications and resources within the enterprise. Because of this, virtualizing a Tier-1 application requires rigorous planning of the I/O strategy. There are five steps to this:
 Identify the I/O fabrics that the Tier-1 applications will use (it may very well be “all of them”).
 Quantify the data flows for each fabric when the application was operating on a standalone system.
 Estimate Live Migration I/O needs for failovers and evolution. Note that most Live Migration traffic will be storage I/O; if the data stays within one external array during the Live Migration, Microsoft’s ODX capability can significantly reduce the I/O traffic.
 Determine your primary and secondary I/O paths for multi-pathing on all of your networks.
 Determine QoS levels for the Tier-1 apps.
One simplifying option available is to utilize converged networking adapters that can function on both FC and Ethernet/ FCoE networks. The QLogic QLE2672 is an example of such an adapter; it can be reconfigured in the field to operate on 16Gb FC or 10Gb FCoE/ Ethernet networks.

The size of a dynamically expanding VHD is as large as the data that is written to it. As more data is written to a dynamically expanding VHD, the file increases to a maximum size. A differencing VHD is similar to a dynamically expanding VHD, but it contains only the modified disk blocks of the associated parent VHD. Dynamically expanding VHDs are useful for testing environments because there is less impact if you have to rebuild the VHD. For example, some of the tests performed for this report used multiple dynamically expanding VHDs, each with a different Windows image. Fixed VHDs are recommended for production.

ODX Data Copy Model Offloads Server
Microsoft’s Live Migration offers the ability to move a live virtual machine from one physical server to another. Included are some interesting storage-oriented capabilities that provide added value if you use SANs (especially Fibre Channel SANs). The first is the ODX Data Copy Model. On compatible external storage arrays, ODX provides the ability to move data between LUNs without involving the server. For large data movements, this results in a huge performance improvement.
Improved Live Migration with vFC
Hyper-V’s Virtual Fibre Channel (vFC) is a new capability that augments Live Migration for those end users with Fibre Channel SANs. By creating virtual FC HBAs natively within Hyper-V, Microsoft simplifies migrations by moving the adapter with the virtual machine. This eliminates the need to re-configure network switches after a Live Migration.
Microsoft Hyper-V’s powerful migration capabilities can provide even more utility if likely failover and evolution paths in the private cloud are planned into the framework. This is especially true for migrations to resolve hardware failures, which tend to be done under considerable stress. Planning failover migrations decreases the likelihood of negative performance impacts that may ultimately have to be undone later.
Live VM Migration
Windows Offloaded Data Transfer (ODX) in Windows Server 2012 directly transfers data within or between compatible storage devices, bypassing the host computer.

This diagram shows a Live Migration utilizing vFC. The 2-port virtual HBA ping-pongs from the first port to the second port, avoiding traffic disruption during the live migration.
Traditional Data Copy Model
ODX Data Copy Model
1. A user copies or moves a file or this occurs as part of a virtual machine migration.
2. Windows Server 2012 translates this transfer request into an ODX and creates a token representing the data.
3. The token is copied between the source server and des- tination server.
4. The token is delivered to the storage array.
5. The storage array internally performs the copy or move and provides status information to the user.

16Gb Fibre Channel Helps Close the Storage Migration Window
A process known as Live Storage Migration allows for a non-disruptive migration of a running VM disk files between to different physical storage devices. This process allows for the virtual machine to remain running with no need to take its workload offline to move the VM’s files to a different physical storage device. Additional use cases for Live Storage Migration include migration of data to new storage arrays or larger capacity, better performing LUNs. NPIV zoning and LUN masking must be properly configured to ensure the VM and host server continue to have access to the storage after the migration is completed. Live Storage Migration across a 16Gb Fibre Channel link can finish in half the time it takes a 8Gb Fibre Channel link. All paths related to Live Storage Migration should be supported by high performance networks in order to reduce the time it takes to evacuate storage safely to a new destination and resume normal operations. Additionally, 10GbE links can replace 1GbE links to ensure proper bandwidth exists for Live Storage Migration in Ethernet environments.

8300 Series CNAs Offload the VM Kernel from Switching Virtual NICs
Single Root I/O Virtualization is a standard that allows one PCI Express (PCIe) adapter to be presented as multiple separate logical devices to virtual machines for partitioning adapter bandwidth. The hypervisor manages the Physical Function (PF) while the Virtual Functions (VFs) are exposed to the virtual machines. In the hypervisor, SR-IOV capable network devices offer the benefits of direct I/O, which includes reduced latency and reduced host CPU utilization. With SR-IOV, pass through functionality can be provided from a single adapter to multiple virtual machines through Virtual Functions. To deploy SR-IOV today, an organization needs to ensure a minimum level of infrastructure (server hardware and OS) support for SR-IOV. In contrast, QLogic NPAR technology can similarly be used today without the minimum levels of dependencies of SR-IOV.

In Transaction Intensive and Bandwidth Intensive Environments
For virtualized environments, the most critical measure of performance is the ability to scale as the number of VMs and application workloads increase. In testing conducted by QLogic, the QLogic QLE2672 delivered three times the transactions and double the bandwidth of 8Gb Fibre Channel Adapters. The QLE2672 also demonstrated a 50% advantage over competitive products for read-only performance and 25% better mixed- read-write performance. The superior performance of QLogic 16Gb Fibre Channel Adapters translates to support for higher VM density and support for more demanding Tier-1 applications.
QLogic achieves superior performance by leveraging the advanced 16Gb Fibre Channel and PCIe® Gen3 specifications—while maintaining backwards compatibility with existing Fibre Channel networks. The unique port-isolation architecture of the QLogic FlexSuite adapters ensures data integrity, security and deterministic scalable performance to drive storage traffic at line rate across all ports. QoS enables IT teams to control and prioritize traffic. And paired with adapter partitioning technology the QLE2672 can deliver capacity on demand and multitenant feature requirements of highly virtualized environments.
More Virtual CPUs for scaling Tier-1 Apps
If you’re concerned about hosting tier-1 apps on VMs, the argument about virtualizing tier-1 apps is over. Even flagship enterprise applications such as Microsoft SQL Server 2012 and Exchange 2010 have adopted server virtualization as a best practice. In fact the CPU, memory, storage and networking requirements are well documented by Microsoft.
In the example on the right, a mission-critical OLTP Workload running on a single SQL Server 2012 VM demonstrates linearly increasing transactional performance and reduced transaction response times as the number of virtual CPUs assigned to the workload are increased to the maximum of 64 now supported on Hyper-V.
Scalability with 16Gb FC
Throughput
Bandwidth refers to the maximum potential volume. Throughput is the actual volume. Both are measured as the amount of data transferred in a given time or megabytes per second (MBps).
The number of transactions processed per second and the average response time were monitored as virtual CPUs were increased from 4-64. The OLTP workload and concurrent user counts remained constant.

10000 Series FabricCache Adapters Cache Hot VM Data
The 10000 Series is the industry's first caching SAN adapter. This new class of server- based PCIe SSD/Fibre Channel HBAs uses the Fibre Channel network to cache and share SAN metadata. Adding large caches to servers places the cache closest to the application and in a position where it is insensitive to congestion.
An advantage to this approach is that PCIe flash based caching can be shared and replicated in different servers for high-availability and for cache coherency across migrating servers in a virtual machine cluster. With the FabricCache architecture, the new generation of PCIe SSDs provide redundancy and fail-over for a new level of enterprise-class availability.
