VIRTUALIZATION 3.5

• Network I/O Control (NIOC) - Leverage network I/O control to deﬁne priority access to network resources

according to established business rules. NIOC monitors the network for congestion and automatically shifts

resources to your highest-priority applications. New in vSphere 6 is the ability to guarantee service levels by using

the provided capabilities to preserve bandwidth.

Limited, no built-in detection of known

network types such as those in VMware’s

Network Resource Pools

No, this is not comparable to NIOC. There are

no guarantees. Individual vNIC proﬁles can be

conﬁgured to limit bandwidth, and Scheduler

can move entire workloads to other hosts, but

no methods exist for automated and policy-

based network resource management

Provisioning

• Host Proﬁles and Auto Deploy - Gain the advantage of rapid server deployment with centralized image

management. Eliminate conﬁguration drift by applying host proﬁles and centrally manage compliance through

vCenter Server

Bare-metal deployments through SCVMM lack

proﬁle compliance and the ability to address

conﬁguration drift

Not included with base oering, requires

purchase of additional components of Red

Hat Satellite

– Provision Stateless - vSphere hosts in Memory

No No

– Stateless Caching - Ensure availability in stateless environments

No No

– Stateful Install Mode - Leverage Auto Deploy’s infrastructure to deploy vSphere to non-stateless instances

No No

Automated Infrastructure Upgrades and Updates

• Simple Upgrades Without Downtime - Maintain system uptime and leverage the capabilities of vMotion and

support for mixed cluster conﬁgurations to upgrade between versions, without the need for downtime or the

purchase and conﬁguration of hardware for a new cluster

No, upgrade involves requirement for

additional servers due to lack of support for

mixed version nodes in the same cluster

Upgrades to RHEV-M remove high availability

and live migration from the environment.

Must ensure the storage pool manager role

properly transfers over to another host in the

cluster

• Virtual Hardware Management - Upgrade virtual hardware and tools with a single click or orchestrate and schedule

upgrades via vCenter Update Manager

No, lacks automation for integration service

upgrades. Further, System Center doesn’t

support upgrading gen 1 to modern gen 2

virtual machines

N/A, RHEV only has one type of virtual

machine

Host Patch Management

• Integration with VMware DRS - Enable zero downtime ESXi host patching with maintenance mode, leveraging

vMotion and DRS to move running workloads to other hosts in the cluster

Possible with multiple tools including SCVMM,

SCCM, and Cluster-Aware Updating. Multiple

tools make auditing and reporting dicult to

manage

• Recalled Patch Management - View a list of recalled patches through Update Manager and setup automated email

notiﬁcations for recalled patches. Update Manager will mark hosts with recalled patches as non-compliant and

delete the patches from its repository to prevent any future installation. Upon release of ﬁxed updates, Update

Manager will notify the users of new patches and provide details on resolving potential issues from recalled patches.

No built-in capabilities to notify and

automatically remove recalled patches.

Software removal package must be created

and targeted for deployment to systems with

bad patch via SCCM
