VIRTUALIZATION 3.5

• VMware API for Storage Awareness (VASA) - Allow storage arrays to integrate with vCenter for management

functionality via server-side plug-ins or vendor providers. Allows a vCenter administrator to be aware of the

topology, capabilities, and state of the physical storage devices available to the cluster.

Possible through SCVMM and limited 3rd

party plugins

Very limited ecosystem and availability of

third party plugins

• vSphere APIs for Multi-pathing - Support for 3rd party multi-pathing plug-in extension modules from vendors such

as EMC, Dell/Equallogic and others to enhance high availability and load balancing for critical applications

Vendor support for only a subset of the

vendors plugins when compared to VMware

No evidence of any third party integrations

for multi-pathing. Limited built in capabilities.

Deep Storage Intelligence

• 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, quotas and QoS capabilities provided by

RHEV cannot guarantee resources and are

only limits that may unnecessarily restrict

VMs from using storage I/O resources when

they are needed.

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

machine’s data to reside based on both storage space and storage I/O resources. Also includes Anity/Anti-Anity

Rules for VMs and VMDKs

No capabilities to balance storage unless using

SMB3,SOFS, & Storage Spaces

Comprehensive conﬁguration, management, and reporting management of storage with ability to specify granular controls

• Uniﬁed Hierarchical Namespace – Manage all available physical disks, logical volumes, and VMFS volumes with a

consistent namespace that eliminates potential conﬂicts

No No

• Customizable Reports and Topology Maps – Increase visibility into vSphere storage space utilization with per-VM,

per-datastore and other reports. Resolve conﬁguration related issues with storage speciﬁc topology maps.

No direct integration with Hyper-V and

System Center, limited capabilities provided

by using SCOM

Limited reporting capabilities provided

through RHEV reporting, a separate

component that is not integrated directly

with RHEV-M

• Centralized Datastore Management - Create, conﬁgure, organize and secure datastores centrally for more granular

control over storage in vSphere environments

No, several tools are required with basic

capabilities only

Very basic capabilities only

• Consumption Based Monitoring and Alerting - Set alerts to notify administrators when they need to procure more

storage or rebalance virtual machines across the available storage with Storage vMotion

No monitoring tools for thin disks No monitoring tools for thin disks

• Virtual Disk Files - Simplify virtual machine storage management. Virtual machines see their own private virtual

disk ﬁles. However, outside the virtual machine, the virtual disks are simply large ﬁles that can be copied, moved,

archived and backed up as easily as any other ﬁle.

Yes Each virtual disk or snapshot is a logical

volume on a volume group
