WHY IS THIS IMPORTANT

• Hypervisor market has more choice•Microsoft upped their game with Hyper-V 2012 and R2 (and

vNext!)• VMware continues to lead the feature race, but gap is closing•Microsoft has begun to innovate and add their own unique

features

MMS Minnesota 2014

HOW THEY’RE THE SAMEFeature vSphere 5.5 Hyper-V 2012 R2

Migrate running VMs vMotion/SvMotion* Live Migr/Live Storage Migr

Multi-NIC Migration Multi-NIC vMotion* SMB3 Live Migration

High Availability vSphere HA and FT* MS Failover cluster, no FT

Replication vSphere Replication* Hyper-V Replication

Storage Protocols FC, FCoE, iSCSI, NFS FC, FCoE, iSCSI, SMB3

Native MPIO Yes Yes

Storage Offloading Yes, VAAI Yes, ODX

DRS Yes* Yes*

Virtual Switches vSwitch, VDS*, Nexus 1kv* Virtual Switch, Nexus 1kv*

Memory Management TPS, Ballooning, Compr. Dynamic Memory

Thin Provisioned VM disk Yes Yes

Hardware Pass-through Yes, including UCS VM-FEX Yes, including UCS VM-FEX* Requires vCenter or System Center Virtual Machine Manager

MMS Minnesota 2014

Compute and High AvailabilityvSphere 5.5 Hyper-V 2012 R2

vCPUs per core or socket, CPU hot plug vCPUs per socket only, no CPU hot plugCPU scheduler based on Unix CPU scheduling based on traditional Windows threading

NUMA exposed to guest OS at 9 vCPU or higher by default or manually

NUMA exposed by default, NUMA spanning disabled per host

vNUMA disabled if vCPU hot plug enabled Dynamic memory disables vNUMA, static RAM recommended for large RAM VMs

No AD required to cluster AD required to clusterVMotion requires a checkmark* Constrained delegation for Kerberos Live Migration

VMotion traffic cannot be encrypted Live Migration can be encrypted with IPSecCan’t VMotion when using SR-IOV Live Migration supported when using SR-IOV

Only option to speed up VMotion is multiple NICs Multi-NIC Live Migration with SMB3 or CompressionvCenter does not certify MSCS, supports SQL clustering now SCVMM, DB, and Library shares can be clustered

Limited virtual graphics options RemoteFX Graphical processing in VMSRM Azure SRM

Fault Tolerance No Fault Tolerance equivalent feature

MMS Minnesota 2014

Memory and Networking

vSphere 5.5 Hyper-V 2012 R2

Memory over commitment No memory over commitment

TPS*, Ballooning, Compression Dynamic memory

VMs can swap to host SSD VMs can swap to shared SSD only

Memory allocated upfront, contention faster Dynamic memory and growing .bin file

No network HA Protected networking

Port groups easily assign VLANs to VMs VLANs assigned per VM manually without SCVMM

Port groups and vSwitch design simple Logical networks, VM networks in SCVMM more complex

vSwitch/vDS advanced features (LBT, CDP, LLDP, Netflow, Network IO Control)

vSwitch advanced features (DHCP guard, Router Advertisement Guard, IPSec offload, network virtualization)

NetQueue DVMQ, vRSS, RDMA for Live Migration

Closed virtual switch (Nexus 1000v, IBM 5000v) Open extensible virtual switch (3rd party extensions)

MMS Minnesota 2014

StoragevSphere 5.5 Hyper-V 2012 R2

Deletes VM folder after SVMotion Leaves old folder after Storage MigrationSCSI Controllers can be hot added SCSI Controllers cannot be hot added

Thin disks Thin disks and differencing disks

Thin disks can be compacted or converted through CLI or live SVMotion

Thin disks can be compacted or converted through GUI or Powershell offline

vSAN No MS hyperconverged optionNFS3 only SMB3!!! Multichannel, constraints, SMB direct

vFRC No native host level SSD cachingHardware RAID card required for ESXi RAID 1 Windows OS has built in RAID 1

Storage DRS No Storage DRSNo native encryption Cluster Shared Volumes can be encrypted

No native memory caching on storage (VMware View only) CSV Block CacheNo Trim support for SSDs Trim support for SSDs

CBT allows easier 3rd party backups No CBT mechanism, 3rd party backups rely on file sys filtersVMDK is proprietary VHD/VHDX is open, can be mounted on any recent MS OS

MMS Minnesota 2014

Management

vSphere 5.5 Hyper-V 2012 R2

vCenter legacy client, Web client VMM, Failover cluster Mgr, Hyper-V Mgr

Smaller attack surface VMM does not equal vCenter

Familiar, easy to set up and go Does not support some BSD and Unix OSes

Hot Add/Remove VM hardware Hot Add/Rem with Gen 2 only (Win8/2012+ VM)

Hot add vNICs, memory, CPU, and SCSI controllers Can’t Hot add vNICs, SCSI Cont, or CPU

Stateless deployment (Auto Deploy) Deployment through VMM, still requires HDD

Smaller attack surface Standard Windows GUI, Limited GUI, or Core

Familiar, easy to set up and go HA, Live/Storage Migr, Repl for $0 on Hyper-V core (with AD)

vApps Can’t Live Migrate from 2008 R2 to 2012+

Rolling cluster upgrades and downgrades No rolling cluster upgrades

Easy performance monitoring in vCenter VMM offers limited performance monitoring

Legacy console connection to VMs only Enhanced Session Mode

Slew of vendor integration Limited vendor integration, but growing

Many VMware advanced features rely on vCenter Very few Hyper-V advanced features rely on VMM

Web client… Automatic VM activationVMware Converter allows easy P2V and V2V MVMC and 3rd party products work, but not great

$$$ COST $$$

• 8 node cluster• 2 CPU sockets per node, 256GB RAM• 125 mission critical VMs• N+1 node availability

• Full “Private Cloud” licensing and support• Hypervisor and Private Cloud ecosphere products

MMS Minnesota 2014

VMware Cost

• VMware solution list price:• 16 vCloud Enterprise licenses = $183,920• Entire vCloud suite included: vCAC, vRealize (vCOPs, Log Insight, Service Manager,

etc.), SRM, vCNS, vSphere Ent Plus• vDP free but feature limited, vDP Advanced costs extra • 1 vCenter Standard license = $4,995

• Not included with vCloud• Production Support Cost per year = $45,984

• Total licensing cost = $183,920• Total support cost = $45,984• Still need Windows server licenses on VMs• Personnel cost = $??,??? But probably lower since VMware well known• VMware licensing more straight forward but costly

MMS Minnesota 2014

Hyper-V and System Center Cost• Microsoft solution list price:

• 8 Windows 2012 R2 Datacenter licenses = $49,240• 8 System Center 2012 R2 Datacenter licenses = $28,856

• Entire System Center suite included: VMM, OM, ORCH, CM, SM, DPM, AppController• Support cost = $????

• Premier Support purchased in $210/hour prepaid blocks• Pay per incident = $259 during 6am-6pm PST, $515 after hours and holidays

• Azure Hyper-V Site Recovery Manager = $16 per VM per month

• Total licensing cost = $78,096• Total support cost = $??,???• Total SRM cost = $2,000 per month• All Windows Server VMs automatically licensed• Personnel cost and training = $??,???• Cost to migrate from VMware = Time + Outages + Planning = $$$$$$

MMS Minnesota 2014

WHAT REALLY MATTERS????

• Each Hypervisor has pros and cons• A lot of FUD is being spread on

the internet, both from VMware and Microsoft•Make sure to use what makes

sense for YOUR BUSINESS!• Sometimes that means both

products!

MMS Minnesota 2014

WHAT DO MY CLIENTS SAY ABOUT HYPER-V?

• Business critical features are the same• HA, Migration, Storage Protocols, MPIO, Replication, etc.

• VMware still leads feature race but Hyper-V is catching up• Most businesses don’t use more “advanced” features• Advanced features fall away if not licensed Enterprise Plus• Some are avoided simply to reduce complexity• Hyper-V is innovating and has some unique features, too

• Cost alone typically drives VMware shops to consider Hyper-V•Which means….
