Recently Vmware introduced vSphere 6.0 and offered great features and compatibility for your infrastructure.

Here I collected all of there features in a single place so you don’t need to shuffle different websites.

Compute

• Increased Scalability – Increased configuration maximums: Virtual machines will support up to 128 virtual CPUs (vCPUs) and 4TB virtual RAM (vRAM). Hosts will support up to 480 CPU and 12TB of RAM, 1,024 virtual machines per host, and 64 nodes per cluster.

Expanded Support – Expanded support for the latest x86 chip sets, devices, drivers, and guest operating systems. For a complete list of guest operating systems supported, see the VMware Compatibility Guide.

• Amazing Graphics – NVIDIA GRID™ vGPU™ delivers the full benefits of NVIDIA hardware-accelerated graphics to virtualized solutions.

• Instant Clone* – Technology, built in vSphere 6.0, that lays that foundation to rapidly clone and deploy virtual machines, as much as 10x faster than what is currently possible today

Storage

• Transform Storage for your Virtual Machines – vSphere Virtual Volumes* enables your external storage arrays to become VM-aware. Storage Policy-Based Management (SPBM) allows common management across storage tiers and dynamic storage class of service automation. Together they enable exact combinations of data services (such as clones and snapshots) to be instantiated more efficiently on a per VM basis.

Network

Network IO Control – New support for per-VM Distributed vSwitch bandwidth reservations to guarantee isolation and enforce limits on bandwidth.

Multicast Snooping – Supports IGMP snooping for IPv4 packet and MLD snooping for IPv6 packets in VDS. Improves performance and scale with multicast traffic.

Multiple TCP/IP Stack for vMotion – Allows vMotion traffic a dedicated networking stack. Simplifies IP address management with a dedicated default gateway for vMotion traffic.

Availability

• vMotion Enhancements – Perform non-disruptive live migration of workloads across virtual switches and vCenter Servers and over distances of up to 100ms RTT. The astonishing 10x increase in RTT offered in long-distance vMotion now makes it possible for data centers physically located in New York and London to migrate live workloads between one another.

• Replication-Assisted vMotion* – Enables customers, with active-active replication set up between two sites, to perform a more efficient vMotion resulting in huge time and resource savings – as much as 95 percent more efficient depending on the size of the data.

• Fault Tolerance (up to 4-vCPUs) – Expanded support for softwarebased fault tolerance for workloads with up to 4 virtual CPUs.

Management

• Content Library – Centralized repository that provides simple and effective management for content including virtual machine templates, ISO images and scripts. With vSphere Content Library, it is now possible to store and manage content from a central location and share through a publish/subscribe model.

• Cross-vCenter Clone and Migration* – Copy and move virtual machines between hosts on different vCenter Servers in a single action.

• Enhanced User Interface – Web Client is more responsive, more intuitive, and more streamlined than ever before.

• Account lockout duration (default 2 minutes)

This only affects SSH and vSphere Web Services connections and not DCUI or console shell access.

Password Complexity

In vSphere 5.x you had to edit /etc/pam.d/passwd

In vSphere 6.0 you can configure using VIM API or through vCenter (PowerCLI cmdlet)

Improved Auditability of ESXi Admin Actions

Prior to vSphere 6.0 vCenter actions would be logged as vpxuser on the ESXi host.

With vSphere 6.0 they are logged with the vCenter username

Enhancements to Microsoft clustering support

Supports Windows 2012 R2 and SQL 0212 running in failover cluster mode and utilizing AlwaysOn Availability Groups

IP V6 Support

Ability to run a faster PVSCSI adapter with MSCS

vMotion support – vSphere 6.0 supports vMotion of MSCS virtual machines on W2008+ clustered across physical hosts using pRDM

Support for NVIDIA GRID vGPU

Enables designers/architects/engineers to run advance, graphics rich apps in remote desktop using NVIDIA 3D graphics and certified app drivers.

Brings workstation class perf even over high-latency networks

Enhances desktop virtualization with immersive graphics, greater security, scalable perf and cost-effectiveness.

Use cases

Increased config maximums enable support for Hadoop/Big Data Workloads. Scale-out apps see greater consolidation ratios and increased perf with larger cluster sizes and greater VM densities. vSphere Big Data Extensions simplifies and automates provisioning and configuring prod Hadoop clusters.

vCenter Server Features

Enhanced vCenter Server Features

vCSA now has same maximums as Windows vCenter

Full interoperability between Windows and vCSA

Architectural changes

Embedded – PSC and vCenter on same VM or

Centralized – PSC and vCenter on separate VMs

Can use embedded PostgreSQL, or Oracle; or MS SQL on Windows vCenter

Platform Services Controller

Combines common services used across vCloud Suite – vCenter SSO, Licensing, Certificate Management Reduces vCenter Server installation

First component to be installed or upgraded

Centralized model recommended for sites with 2 or more SSO solutions

When using centralized model, make PSC highly available (can use 2x PSC + Load Balancer) PSCs replicate – Licenses, Roles, Permissions, Tags

Can’t switch models after deployment

Can’t deploy vCenter with embedded PSC then switch to centralized PSC Can’t change connections between PSCs after installation

Linked Mode Comparison

Can link Windows and vCSA

Automatically enabled as long as vCenters are in the same SSO domain

Removes extra config steps

Full replication of roles and permissions, licensing, tags and policies

Certificate Lifecycle Management

Solution users are created when vCenter Server or vCenter Inventory Service are registered in SSO. These solution users are used as certificate endpoints and are issued certificates instead of individual services. This enables the services associated with a solution user to utilize the same certificate and substantially reduce the number of certificates required to manage the environment.

vSphere 6.0 introduces 2 new components for managing certs:

VMCA (VMware Certificate Authority) – root CA, or can be configured as a subordinate CA to an existing enterprise CA. Resides on PSC and issues signed certs to all vSphere 6.0 components through solution users. Secures the environment by using a CA to generate certs instead of self-signed certs.

VECS (VMware Endpoint Certificate Service) – stores all certs, including 3rd party certs and private keys. No longer have to manually update each vCenter component cert, just store certs in VECS and get vCenter to use them. NOTE – ESXi certs are still stored locally on the host, but can be provisioned by VMCA. Use VECS command line interface – vecs-cli

VMware Certificate Authority

Operates in 2 modes:

Root CA – Creates a self-signed CA cert, to issue other certificates. All other solution and endpoint certs are created and trusted from this self-signed CA cert.

Issuer CA – Generates a CSR that is signed by an Enterprise CA, or a commercial CA. After the CSR is signed the admin configures the VMCA to use this cert. This mode requires that all issued default certs are replaced after implementation

Certificate Replacement Options

VMCA Default – VMCA creates a self-signed root cert. This can be regenerated as and when required.

VMCA Enterprise – the Enterprise CA issues a signing cert to the VMCA. If the VMCA has already been used in default mode, all the old certs will have to be regenerated before migrating to the enterprise mode.

Custom Install – to use other CA or 3rd party certs, VMCA will need to be disabled as the CA for vCenter. Custom certs will have to be installed manually in the VECS for each solution user and endpoint.

vMotion Enhancements

Cross vSwitch vMotion

vMotion between vSwitches. Must be on same L2 network as the IP address of the VM will not change. Can move from

vSS to vSS vSS to vDS vDS to vDS

but not vDS to vSS because VM metadata is transferred.

This increases Agility, and Business reliability by increasing the availability of the app during maintenance.

Cross vCenter vMotion

Can migrate to a vCSA (and eliminate Windows & SQL licenses)

Can migrate from vCSA to Windows vCenter to enable use of a SQL cluster

Can migrate between vCenters when doing a vCenter upgrade to avoid impact on VM management. Can migrate between hosts, datastores, and networks at the same time.

Cross vCenter vMotion Enhancements

Requirements: vCenter 6.0

Web Client – must be same SSO domain API – can be different SSO domains 250Mbps network bandwidth

Features:

VM UUID remains the same (not the same as Managed ID, MoRef, BIOS UUID)

Data and settings are preserved – includes VM UUID, event/alarm/task history/resource settings (shares/reservations/limits). DRS settings are also preserved including (anti)affinity rules, automation level, startup priority, host isolation response.

MAC addresses are preserved – when moving a VM from a vCenter Server, the MAC is added to an internal blacklist to prevent it being reused.

Long Distance vMotion

Latency must be 150ms or less

Socket buffer resizing techniques are supported to ensure successful migrations Any storage system and both VMFS and NFS are supported

Can be used for disaster avoidance

Long Distance vMotion Requirements

Latency 150ms or less Bandwidth 250Mbps

Same L2 network (can use VXLAN, NSX L2 Gateway services, or GIF/GRE tunnels)

Content Library

Simplifies distribution of VM templates

Centrally stores and manages published VM templates

Automatically distributes the template changes to other sites

Supports lifecycle management when content is updated

Content Library Catalog

Supports 3 types of libraries

Local – available only to the local ESXi server

Published – Published for subscribers

Subscribed – synchronizes with a published library

Published can be “Immediate Download or Automatic Subscription” or “On Demand Subscription”

vSphere Web Client

2 notable enhancements

Can access multiple vCenters from a single Web interface New Recent Tasks pane

Old vSphere Client (C#) is still available, but can’t configure any new features from 5.1 onwards.

vSphere Web Client Enhancements

Better performance: Login13x faster Right-click 4x faster

Chrome or IE preferred, Firefox supported but slower. Perf charts 2x quicker

VMRC integrated

Usability Improvements:

New drop-down menu to aid navigation

Right-click menu flattened improving consistency across the UI

Task pane relocated to bottom of screen, making it easier to view recent tasks, and make more consistent with vSphere Client.

UI is now dockable, allowing customization

Use Cases

PSC – removes services from vCenter and makes them centralized for vCloud suite. Single point of management for roles/perms/licensing. Reducing vCenter installation options makes install/upgrade faster and easier. All vCenter services are now on vCenter server, reducing complexity. VUM is the only stand-alone product installer.

Enhanced Linked Mode – Centralized interface. PSCs replicate automatically, for Windows and vCSA instances.

Cross vSwitch vMotion – Increases agility, availability, and reliability.

Cross vCenter vMotion – Migrate between vCSA and Windows vCenter (reduce cost/increase reliability), migrate across local/metro/continental distances. Replace vCenter server without disruption, Use resource pooling across vCenter servers where multiple vCenters were used due to scalability limits. Long Distance vMotion – permanent migration, disaster avoidance, balance load, migrate across physical servers that are geographically dispersed without interrupting apps.

Content Library – helps with storage and consistency. Centrally manage VM templates, distribute

globally, accomplish VM template lifecycle management.

vSphere Web Client – improved performance and usability makes it equivalent to vSphere Client

Networking and Storage Features

Network and storage enhancements

NIOC upgraded to v3 – improved network resource reservation and allocation

VVOLs – different and improved storage architecture, VM centric instead of LUN or volume centric

Network I/O Control

New bandwidth reservation for System Traffic based on capacity of physical adapters. Enables reservation of capacity for a vNIC or distributed Port Group

Also enables fine-grained resource control at the VM network adapter level.

Multiple TCP/IP stacks

ESXi 4.x and 5.x only had one network stack for all vSphere services

ESXi 6.x has improved scalability and offers flexibility by isolating vSphere services to their own stack Also allows vMotion to work over a dedicated L3 network.

NFC traffic can be isolated to its own network , rather than sharing the management network, so a clone operation wouldn’t affect management.

Each TCP/IP stack will have its own:

• Memory heap

• ARP tables

• Routing table

• Default gateway

VMware Virtual Volumes

Enables array based operations at the virtual disk level Transforms the data plane of the SAN and NAS systems

Implements improved storage arch enabling operations to be conducted at the VM level using native array capabilities

Supports data operations offload to storage arrays

Eliminates the need to provision and manage large LUNs or volumes per host Simplifies operations through policy-driven automation.

Primary objective is to bring the benefits of SDDC to stage

For vSphere administrator – Enables on demand access to the right kind of storage and storage services For storage administrator – Provides an efficient way to provision and manage storage

Virtual Volumes Storage Architecture

Each VM is assigned its own storage policy All VMs use storage from same common pool

When provisioning, different buckets with different policies need not be considered VM policy can be changed without moving the VM to a different LUN.

Storage Architecture Components

VASA – vSphere APIs for Storage Awareness Provider

Protocol Endpoints

Storage Container

clip_image004_thumb

VASA Provider

Exposes storage services which a VVOL array can provide Understands VASA APIs for operations, such as creation of VVOL files Serves as the control plane element of VVOLs

Can be implemented in the firmware of an array

Can be in a separate VM that runs on the cluster which is accessing the VVOL storage

Protocol Endpoints

Access points that enable communication between ESXi hosts and storage array systems Configured as part of the physical storage fabric and accessed by standard storage protocols

Help ensure that the performance of VVOLs is not affected by the policy management activities Separates the access points from the storage resulting in fewer access points

Storage Container

A logical construct for grouping VVOLs

Enables a Storage Admin to isolate or partition the storage according to requirements

Maps to a vSphere Datastore – concept of Datastores is deeply embedded in vSphere, and used for various purposes such as administrative access control

VVOLs provide a corresponding object to enable users to logically manage storage

Storage-Policy Based Management Framework

Delivers an orchestration and automation engine that translates storage requirements expressed in a VM storage policy, into granular provisioning capabilities

Uses VASA and makes Storage Capabilities visible in the vCenter interface

vSphere Admins can use VM Storage Policies to deliver storage requirements and capabilities

SPBM uses VVOLs to recommend compliant datastores for VM placement, and to transparently turn on the necessary data services based on native array capabilities

New De-Facto Storage Paradigm

VVOLs is the logical extension of virtualization into the storage world

VVOLs along with VSAN provides the foundation for software defined storage in the SDDC

Benefits of Virtual Volumes

• Simplify storage operations:

Allows separation of provisioning and consumption of storage for VMs.

Simplifies operations through policy driven automation, enabling agile storage consumption and dynamic adjustments in real time when needed.

Automated policy enforcement simplifies monitoring and ensures compliance of storage service levels.

• Simplify delivery of storage service levels

Provides fine control over storage resources and native array data services down to the VM level, admins can create exact combinations and service levels on a case by case basis. Policy driven automation ensures desired service levels are constantly met, and enables dynamic adjustments in real time when needed to quickly adapt to changing requirements

• Improve resource utilization

Enables more flexible, VM-centric consumption of storage capacity and services, eliminating overprovisioning issues.

Enables dynamic adjustments in real time, through automation.

Use Case

Use a storage container to enable DR:

• Create a new VM and specify that it needs to be made available in a disaster

• The PE facilitates communication to the storage array, indicating that it needs DR

• The array then creates a set of VVOLs and ensures they are replicated

• Only the single VM is replicated not the whole datastore

• Because the VM at the DR site is understood to be a replica, only one VM will be visible
