4. vCenter Server
§ No change to architecture § All services are local • Reduced complexity
§ Supports 1-1000 Hosts / 1-10,000 Virtual Machines
CONFIDENTIAL 7
Configuration #1 - Multiple vCenter Server 5.5
By Default § Each site is independent § Does not provide a single pane of glass view § SSO builtin replication
§ SSO Users & Groups § SSO Policies § Identity sources
§ Use custom installer to expend vSphere.local domain
§ Linked Mode § Maintains single pane of glass § Replicates Licenses, permissions and roles

Upgrading 5.1 Architecture when Distributed
Upgrade the current vCenter Single Sign-On 5.1 to 5.5 Deploy a new vCenter Single Sign-On server to the vCenter Server or single virtual machine specifying that vCenter Single Sign-On is an additional instance placing it in the already created vsphere.local security domain
On the vCenter Server install the vSphere Web Client 5.5 using the local vCenter Single Sign-On instance On the vCenter Server install the vCenter Inventory Service using the local vCenter Single Sign-On instance On the vCenter Server install the vCenter Server using the local vCenter Single Sign-On instance Power off and remove the original separate vCenter Single Sign-On instance

Utilize a Management Cluster 1. Run multiple vCenter components together on same
virtual machine • Database excluded (for performance)
2. Recommendations – 3 vSphere Hosts (minimum) – Enable vSphere HA
• Enable VM Monitoring
– Enable DRS • Affinity / Anti Affinity Rules
– Understand and configure service dependency order

§ Why? • In the rare case SSO goes wrong, users can log into Web
Client and troubleshoot
• Simple Install puts all components in a single server • VMware’s suggested best practice
CONFIDENTIAL 14
Custom Install • Why would you run this? – Distribute services across
multiple servers
• Customize location • Advanced configurations
• E.g. additional vCenter servers

vCenter Single Sign-On Recomendations • Embedded vCenter Single Sign-On reduces complexity
– Up to 8 instances peer to peer – 12ms Latency
• Same vSphere.local domain – Single point of administration
• Centralized vCenter Single Sign-On – 3 or more Solutions (vCenter, vCAC, etc) – Redundancy required (HA, NLB) – Single pane of glass (per central instance)
• All configurations – Backup each instance – Recovery of additional instances may require manual re-sync (if changes were made)
• Worst case, redeploy new and reregister solutions

Choose the correct deployment option! The installation choices of the vCenter Single Sign-On will dictate how SSO functions
• Middle Radio Button – Merges Lookup Services – For SSO HA, requires loadbalancer
• Bottom Radio Button – Configures new Lookup Services – For multiple deployments • http://kb.vmware.com/kb/2058239 and http://kb.vmware.com/kb/2058249
CONFIDENTIAL 17
What Is the vCenter Server Inventory Service?
Maintains a cache of the vCenter Server inventory
– (VMs, Hosts, etc) Reduces the load on VPXD by offloading client requests
Installs locally to vCenter Server (do not install to a separate virtual machine)
– Separate spindles or SSD (better)
Enables use of Tags Enables Storage Based Policy Management
– Remember to backup Inventory service data files to provide recovery of tags and SBPM
Inventory Service provides a query service for the web client
CONFIDENTIAL 18
vSphere Clients
vSphere Web Client (use this) – Primary client for vSphere administrators – Matched functionality to legacy VI Client – New functionality available only thru the Web Client – Browser based on Windows and Mac – Install local to vCenter Server
• If installing to alternative drive, enable 8.3 paths
vSphere Client (not this) – Available with legacy features – Use it for all supported host client functionalities – Update Manager Remediation – Added HW10 support (5.5 Update 2)

VMware Platform Services Controller We’re adding additional services No longer just Single Sign-On
Platform Services Controller includes a set of common infrastructure services that are used by the vCloud Suite (vCenter, vCAC, vCOPS, etc)
• Single Sign-On (SSO) • Licensing
• Certificate Authority • Certificate Store
• Service (Product) Registration
• Other Services will be added in future releases
Platform Services Controller supports data replication

vCenter Server – Embedded PSC vs. External PSC vCenter Server with Embedded PSC • Sufficient for most environments • Easiest to maintain and deploy
• Supports up to 8 vCenter Servers • Supports embedded & external vCenter DB
• Supports Windows & Appliance
vCenter Server with External PSC • For larger customers with numerous vCenter
Servers
• Reduces footprint by sharing Platform Services Controller across several vCenter Servers
• Recommended for 3+ vCenter Servers per site
• Supports embedded & external vCenter DB • Supports Windows & Appliance
