Networking Improvements
• Network I/O Control - per-VM bandwidth reservations on
Distributed vSwitches
• Multicast Snooping – IGMP snooping for IPv4, MLD for IPv6, for
snooping traffic on Distributed vSwitches
• Dedicated TCP/IP stack for vMotion – allows discrete management
of vMotion traffic, including dedicated default gateway (previously
shared with all VMK networking)

Introduction of Virtual Volumes (VVols)
• Introduction of “Software Defined Storage” into the vSphere
platform
• Leverages existing investment in block storage (iSCSI, FC, FCoE)
• Decouples storage capabilities from storage volumes
• Highly granular control of storage capability – a VM can span multiple VVols
to ensure each aspect (metadata, swap file, individual VMDKs) are catered for
• Offloads much of the workload to the storage platform (utilising VASA)
• Allows greater storage self-service for VMware Admins
14. 19/10/2016 14
Other Enhancements
• Content Library – centralised repository of items such as VM
Templates, ISO Images and scripts, shared through publish/subscribe
model
• Enhanced User Interface – vSphere web client improved (faster,
cleaner, more intuitive). As of vCenter 6.0u1, Update Manager is
now integrated with the web client.
• Old Windows C# (“fat”) client is still present, though cannot manage
features introduced after vSphere 5.1 (no VVols, no VSAN, etc)

vSphere Licensing simplified
• Previously six vSphere Editions:
• vSphere Essentials/Essentials Plus
• vSphere Standard
• vSphere Enterprise Plus
• vSphere with Operations Management Enterprise Plus
• vSphere Enterprise
• vSphere with Operations Manager Standard
• vSphere with Operations Manager Enterprise
• The last three have been discontinued (support still available until 2020)
• Pricing has risen for the remaining Standard and Enterprise Plus licenses.

What is it?
• vCenter is a set of components used to manage a vSphere
environment.
• Two key components:
• Platform Services Controller
• vCenter SSO, License Service, Lookup Service, VMware Directory Service, Vmware
Certificate Authority
• vCenter Server Services
• vCenter Server, vSphere Web Client, vCenter Inventory Service, vSphere Auto Deploy,
vSphere ESXi Dump Collector, vSphere Syslog Collector/VMware Syslog Service
•Other components such as Update Manager installed separately

Deploying vCenter Server
• Unless you really need the Windows vCenter server, or must keep
your DB in SQL, deploy the VCSA
• As of vCenter v6.0u2, the Windows C# client is no longer required
for “native” vSphere functionality – use the web client
• Two primary deployment options:
• vCenter server with embedded PSC (single VM required)
• Separate PSC and vCenter servers (minimum of two VMs required)
23. 19/10/2016 23
vSphere Update Manager
• Although fully integrated into the vSphere Web Client, Update
Manager still requires separate installation:
• 64-bit Windows as a host OS
• SQL or Oracle database – does not integrate into the Postgres database
installed as part of the VCSA.
