10. Hyper-V | XenServer | vSphere Comparison XenServer 6.0 active VMs per host varies based on Server/VDI workload, with PVS/IntelliCache & HA on/off Maximum VMs on a Cluster (Resource Pool) on XenServer 6.0 based on a maximum of 50-60 concurrent protected VMs per host with HA enabled. Host physical memory is capped at 32GB thus maximum VM memory is also restricted to 32GB usage. For clustering/high availability, customers must purchase vSphere vSphere 5.0 Enterprise Plus is the only edition that supports 32 vCPUs. All others support 8 vCPUs within a virtual machine. Maximum number of Virtual CPUs per Host is not documented in the Citrix XenServer 6.0 Configuration Limits documentation XenServer 6.0 Information: http://www.citrix.com/site/resources/dynamic/salesdocs/Citrix_XenServer_6_Configuration_Limits.pdf vSphere Hypervisor / vSphere 5.0 Ent+ Information: http://www.vmware.com/pdf/vsphere5/r50/vsphere-50-configuration-maximums.pdf and http://www.vmware.com/products/vsphere-hypervisor/faq.html

Quality of Service (QoS)Consistent level of performance based on SLAs Resource MeteringTrack historical data for virtual machine usage Data Center Bridging (DCB)Converge network traffic to provide enhanced QoS

15. Hyper-V | XenServer | vSphere Comparison Memory Optimization is a feature found only in XenServer 6.0 Advanced edition and higher. XenServer collects processor use, memory usage, and network I/O rates for the entire host system, as well as each individual virtual machine. Free edition limited to 24 hours of historical data. A number of Converged Network Adaptors are supported within the XenServer 6.0 HCL however no official documentation can be found for DCB and XenServer 6.0. Without vCenter, Resource Metering in VMware vSphere Hypervisor is only available on an individual host by host basis. Quality of Service (QoS) is only available in the Enterprise Plus edition of vSphere 5.0 XenServer 6.0 Information: http://www.citrix.com/site/resources/dynamic/salesdocs/Citrix_XenServer_6_Configuration_Limits.pdf, http://support.citrix.com/servlet/KbServlet/download/28751-102-673823/XenServer-6.0.0-reference.pdf, http://support.citrix.com/article/CTX123996 and http://www.citrix.com/English/ps2/products/subfeature.asp?contentID=2300456 vSphere Hypervisor / vSphere 5.0 Ent+ Information: http://www.vmware.com/pdf/vsphere5/r50/vsphere-50-configuration-maximums.pdf and http://www.vmware.com/products/vsphere/buy/editions_comparison.html

16. Comparison Security& Multitenancy

17. Hyper-V | Extensible Switch • New Security & Isolation Capabilities • PVLANs • ARP/ND Spoofing Protection | DHCP Guard Protection • Virtual Port ACLs | Trunk Mode to VMs • Monitoring & Port Mirroring • Windows PowerShell | WMI Management • Performance Enhancements: DVMDq | IPsec Task Offload | SR-IOV Extensible Switch • Extensible by PartnersOpen platform that lets multiple Partners provide extensions that arewritten to standard Windows API frameworks. These Partners include: • Cisco: Nexus 1000V & UCS Virtual Machine Fabric Extender (VM-FEX) • NEC: OpenFlow • 5nine: Virtual Firewall 3.0 • InMon: sFlow

18. Hyper-V | Physical Security • BitLocker Drive Encryption • Provides a solution for securing data within deploymentsoutside of the datacenter. BitLocker in Windows Server 2012enables the IT administrator to: • Encrypt local disk storage (DAS) • Encrypt traditional failover cluster disks • Encrypt Cluster Shared Volumes 2.0 • BitLocker offers a solution to meeting compliance demands. Physical Security

19. Hyper-V | XenServer | vSphere Comparison The vSphere Distributed Switch (required for PVLAN capability) is available only in the Enterprise Plus edition of vSphere 5.0 and thus far, seems to be replaceable (By Partners such as Cisco/IBM) rather than extensible. ARP Spoofing, DHCP Snooping Protection & Virtual Port ACLs require either vShield App or a Partner solution, all of which are additional purchases on top of vSphere 5.0 Enterprise Plus Port Monitoring and Mirroring at a granular level requires vSphere Distributed Switch, which is available in the Enterprise Plus edition of vSphere 5.0. No XenServer documentation can be located that discusses Partner Extension s to the XenServer Open vSwitch. XenServer 6.0 Information: http://support.citrix.com/servlet/KbServlet/download/28748-102-664877/XenServer-6.0.0-dvs_controller.pdf, http://support.citrix.com/servlet/KbServlet/download/28751-102-673823/XenServer-6.0.0-reference.pdf and http://www.citrix.com/English/ps2/products/subfeature.asp?contentID=2300456 vSphere Hypervisor / vSphere 5.0 Ent+ Information: http://www.vmware.com/products/cisco-nexus-1000V/overview.html, http://www-03.ibm.com/systems/networking/switches/virtual/dvs5000v/, http://www.vmware.com/technical-resources/virtualization-topics/virtual-networking/distributed-virtual-switches.html, http://www.vmware.com/products/vshield-app/features.html and http://www.cisco.com/en/US/prod/collateral/switches/ps9441/ps9902/data_sheet_c78-492971.html

20. Hyper-V | XenServer | vSphere Comparison • Dynamic Virtual Machine Queue (DVMQ) is not supported by either XenServer or vSphere, which both support regular VMq (known as NetQueue on vSphere). • Whilst XenServer 6.0 provides SR-IOV support, the release notes state: “If your VM has an SR-IOV VF, functions that require VM mobility are not possible. For example, Live Migration, Workload Balancing, Rolling Pool Upgrade, High Availability and Disaster Recovery, cannot be used. This is because the VM is directly tied to the physical SR-IOV enabled NIC VF. In addition, VM network traffic sent via an SR-IOV VF bypasses the vSwitch, so it is not possible to create Access Control Lists (ACL) or view Quality of Service (Qos).” (http://support.citrix.com/article/CTX131381) • DirectPath IO, whilst not identical to SR-IOV, aims to provide virtual machines with more direct access to hardware devices, with network cards being a good example. Whilst on the surface, this will boost VM networking performance, and reduce the burden on host CPU cycles, in reality, there are a number of caveats in using DirectPath I/O: • Very small Hardware Compatibility List • No Memory Overcommit • No vMotion (unless running certain configurations of Cisco UCS) • No Fault Tolerance • No Network I/O Control • No VM Snapshots (unless running certain configurations of Cisco UCS) • No Suspend/Resume (unless running certain configurations of Cisco UCS) • No VMsafe/Endpoint Security support • No such restrictions are imposed when using SR-IOV, ensuring customers can combine the highest levels of performance with the flexibility they need for an agile infrastructure. • XenServer 6.0 Information: http://www.citrix.com/site/resources/dynamic/salesdocs/Citrix_XenServer_6_Configuration_Limits.pdf, http://www.citrix.com/English/ps2/products/subfeature.asp?contentID=2300456, • vSphere Hypervisor / vSphere 5.0 Ent+ Information: http://www.vmware.com/pdf/Perf_Best_Practices_vSphere5.0.pdf

30. Hyper-V | XenServer | vSphere Comparison XenServer 6 provides Automated VM Protection & Recovery in the Advanced edition and higher XenServer 6 provides a Site Replication capability in the Platinum edition, however replication is provided by a storage vendor, not inbox from XenServer hosts. XenServer 6 provides HA in the Advanced edition or higher. The vSphere Hypervisor has no high availability features built in – vSphere 5.0 is required. VMware Data Recovery is available in Essentials Plus and higher vSphere 5.0 editions vSphere Replication is a feature of VMware vCenter Site Recovery Manager (SRM), which is available in 2 editions and is a chargeable addition to vSphere 5.0 VMware HA is built in to Essentials Plus and higher vSphere 5.0 editions VMware have made APIs publicly available, but actual application monitoring is not included Features available in all editions that have High Availability enabled.

31. Hyper-V | XenServer | vSphere Comparison Maximum VMs on a Cluster (Resource Pool) on XenServer 6.0 based on a maximum of 50-60 concurrent protected VMs per host with HA enabled. High Availability/vMotion/Clustering is unavailable in the standalone vSphere Hypervisor VMware does not support VM Guest Clustering using iSCSI storage. VMware does not support VM Guest Clustering using File Based Storage i.e. NFS VMware does not support the vMotion of a VM that is part of a Guest Cluster VMware does not support the use of Memory Overcommit with a VM that is part of a Guest Cluster No XenServer documentation can be found that details the number of simultaneous live migrations over either 1GB or 10GB Ethernet.

32. All this is great, but what about…. Both VMware vSphere (ENT) and Citrix XenServer 6.0 (ENT) have features for load balancing VMs, and offer power management of hypervisor hosts. Is there anything similar in Hyper-V? Hyper-V, in the box, has the engine to move virtual machines around without interruption, and when combined with System Center 2012 unlocks capabilities such as Dynamic Optimization and Power Optimization

33. All this is great, but what about…. Within vSphere 5.0 Enterprise Plus, VMware offer the ability to centrally deploy the hypervisor down to physical hardware. What are my choiceswith Hyper-V? With Hyper-V being contained within a WIM file, IT admins have a variety of choices – DVD, USB, WDS, MDT 2012, or, within System Center 2012, Configuration Manager or Virtual Machine Manager.

34. All this is great, but what about…. VMware has a feature known as Fault Tolerance, which runs a hot-standby of a VM on another host, to take over should the primary host fail – beat that Microsoft! Whilst attractive on paper, this is a feature where the cons, outweigh the pros. Using FT means sacrificing: • Scale & Density (4 FT VMs per Host & no Memory Overcommit) • Performance (1 vCPU per FT VM & EPT/RVI disabled) • Hot-Plug disabled, no snapshots, backups etc. • Hyper-V has comprehensive guest clustering, 3 levels of availability, and for the highest levels of availability, we partner with Stratus (ftServer).
