VIRTUALIZATION 3.5

Automated Resource Monitoring and Alignment

• Align Computing Resources with Business Goals - Ensure ﬂexibility and ecient utilization of hardware resources.

VMware DRS continuously monitors utilization across resource pools and intelligently allocates available resources

among virtual machines based on pre-deﬁned rules and policies. VMware DRS dynamically responds to changing

virtual machine requirements using VMware vMotion to move virtual machines non-disruptively between servers.

Limited, Hyper-V doesn’t have esource pools Limited capabilities provided by scheduler.

Optimizer, a separate instance installed on

top of RHEL, seeks to optimize memory

balance but is in tech preview and It’s not

supported by GSS at this time. Optimizer

only makes recommendations, which can

conﬂict with other CPU scheduler

recommendations.

• DRS Virtual Machine Host Anity and Anti-Anity Rules - Set constraints that restrict placement of a virtual

machine to a subset of hosts in a cluster and keep virtual machines paired or separated. This feature is useful for

enforcing host-based ISV licensing or keeping sets of virtual machines on dierent racks or systems for availability

reasons.

Anti-Anity support only.

Anity rules limited to pinning VMs to

speciﬁc hosts, not VM pairing. Requires both

SCVMM and Failover Cluster Manager

Limited, cannot set DRS anity/anti-anity

groups or select subset of hosts for

placement

• Virtual Disk Anity and Anti-Anity Rules – Restrict placement of virtual machine disks with Anity/Anti-Anity

Rules for VMDKs

No No

• Optimized Power Consumption - Easily conﬁgure vSphere’s Distributed Power Management feature at the cluster

and host level. Compare historical demand to place and bring hosts out of standby mode to meet the needs of the

infrastructure while allowing for reduced power consumption and costs.

Power Management requires a minimum

cluster size of ﬁve due to reliance on Windows

Failover Clustering

Power management with RHEV is complex

and must be conﬁgured at the host level. If

you conﬁgure a power savings policy you

cannot conﬁgure a load balancing policy, it is

one or the other only

• Storage DRS - Automated load balancing uses storage characteristics to determine the best place for a given virtual

machine’s data to reside both when it is created and when it is used over time based on both storage space and

storage I/O resources

No capabilities to balance storage workloads

unless using SMB3/SCOFS/Storage Spaces

• Intelligent Initial Placement – Initially place workloads based on known storage environmental factors such as

storage capacity and storage I/O utilization

No, VMM Intelligent Placement only considers

free space when making placement decisions

• Storage I/O Control (SIOC) - Provides QoS capabilities for storage I/O in the form of I/O shares and limits that are

enforced across all virtual machines accessing a datastore, regardless of which host they are running on and the

type of storage used. Use Storage I/O Control to ensure that the most important virtual machines get adequate I/O

resources even in times of congestion.

No, Hyper-V allows for conﬁguration of

virtual disk limits, but lacks comprehensive

management of storage I/O. Disk limits only

protect resources on the same host and lack

storage awareness

No, there are no comparable capabilities to

SIOC. The only thing you can do is place

quotas on disk spaced used for objects of

conﬁgure I/O limits which may unnecessarily

restrict resources. Note-when quotas are

enabled for a datacenter you must manually

apply quotas for all objects of a datacenter,

one at a time.
