Changes from vSphere 4.x That Affect vSphere
Installation
vSphere 5.x is a major upgrade from vSphere 4.x.
The following changes from vSphere 4.x affect vSphere installation and setup:
• Removal of the service console
• Removal of the VMware® ESX® graphical installer
• A single installer wizard for upgrades and fresh installations
• Installer caching
• Changes to partitioning of host disks:
• All fresh installations of vSphere 5.5 use the GUID Partition Table (GPT) format instead of the MS-DOS style of partitioning.
• Upgraded systems do not use the GPT format, but retain the MSDOS style of partitioning.
• New installations create a 4GB scratch partition.
vSphere Web Client Architecture
The vSphere Web
Client architecture
consists of the following
components:
•
Client component:
•
Supported Web browser•
Server component:
•
vSphere Web Client•
Scalable, backend server•
vCenter Server
•
Inventory Service
Web Browser Application Server vCenter Single Sign-On vSphere Web Client vCenter Server Inventory ServicevSphere vMotion Enhancements
With vSphere 5.1 and later, you can migrate a powered-on
virtual machine (including memory and storage) with vSphere
vMotion, without the requirement for shared storage.
vSphere DRS still requires shared storage when performing
vSphere vMotion operations.

About vCenter Single Sign-On
vCenter Single Sign-On is an authentication service that secures the VMware cloud infrastructure platform.
vCenter Single Sign-On allows vSphere software components to communicate with one another through a secure token mechanism. AD Open LDAP vSphere Web Client Identity Sources vCenter Single Sign-On vCenter Server VMware® vCenter™ Orchestrator™ VMware® vCloud Director®
Security Enhancement: ESXi Firewall
ESXi has a new firewall engine to provide access control to incoming connections on the management network.

About VMFS-5
VMFS-5 provides improvements in scalability and
performance over VMFS-3:
•
The datastore and a single extent can be greater than
2TB.
•
The maximum datastore size is 64TB.•
The maximum virtual disk size is 62TB.•
1MB file system block size, which supports files up to
62TB in size:
•
The file system subblock size is 8KB.•
Efficient storage of small files:
•
Data of small files (less than or equal to 1KB) is stored directly in the file descriptor.•
Raw device mappings have the following maximum sizes:
•
Physical compatibility mode: 64TB•
Virtual compatibility mode: 62TBUpgrading to a VMFS-5 Datastore
You can upgrade a VMFS-3 datastore to a VMFS-5 datastore.
All ESXi hosts that need to access the datastore must first be upgraded to ESXi 5.x.
About Datastore Clusters
A datastore cluster is a collection of datastores that are grouped together without functioning together.
A datastore cluster enabled for Storage DRS is a collection of datastores working together to balance capacity and I/O
operations per second (IOPS) latency.
Relationships Between Host
Clusters and Datastore Clusters
The relationship between host clusters and datastore clusters can be one-to-one, one-to-many, or many-to-many.

Replication
vSphere Replication Architecture
Before you can replicate virtual machines, you must have the vSphere Replication server deployed at both the source site and target site.

vSphere Web Client
How Replication Works
After ensuring that data is consistent at both the source and target sites, the vSphere Replication agent tracks all changed blocks by way of a vSCSI filter.
Changed blocks are replicated based on the RPO. A B C D E A B C D E VMDK Lightweight Delta TCP/44046 A C D Source Target VMDK Replica Redo Log ESXi VR Agent
Managing vSphere Replication
The vSphere Web Client provides vSphere Replication summary
information and enables you to monitor and manage replication for each vCenter Server system in the inventory.
vSphere Replication Compatibility with vSphere
vSphere Replication requires ESXi 5.0 or greater.
vSphere Replication functionality is available with the vSphere Web Client.
• vSphere Replication functionality is available with the VMware
vSphere® Client™ if you install VMware® vCenter™ Site Recovery
Manager™ with the plug-in.
vSphere Replication is incompatible with the following vSphere features:
• VMware vSphere® Fault Tolerance
• VMware® Virtual SAN™, with limitations
vSphere 5.x Enhancements to vSphere HA
Certain vSphere HA features have significantly improved in vSphere 5.x:
• Single log file for operational, day-to-day logging
• Syslog integration
• Error and status reporting
• Recognition of VMware vSphere® Distributed Resource Scheduler™ VM-Host affinity rules
• Cluster status and advanced runtime information in the user interface
• Ability to deploy and reconfigure within seconds, regardless of cluster size
• Removal of dependencies on commonly misconfigured services, for example, DNS
• Host isolation response
• Admission control policies
Admission Control Policy: Reserving Number of Hosts
You can reserve a specific number of hosts to be used for virtual machines when a failover occurs.
The slot size is used to determine whether sufficient failover capacity exists.
Master/Slave Architecture
When you create a vSphere HA cluster, a single host is
elected as the master host. The master host communicates with vCenter Server and monitors the state of all protected virtual machines and of the slave hosts. Management Network vCenter Server Shared Datastores vSphere HA Cluster vpxd Master Host Slave Host Slave Host vSphere HA Agent vSphere HA Agent vSphere HA Agent
Master Host Failure

About Virtual SAN
vSphere 5.5 offers experimental support for Virtual SAN, which is software-defined storage.
Virtual SAN aggregates direct-attached storage disks of ESXi hosts and creates a storage pool that can be used by virtual machines.
Virtual SAN has the following benefits:
• vSphere and VMware® vCenter Server™ integration
• Storage scalability
• Built-in resiliency
• SSD caching
• Converged compute and storage resources
Virtual SAN Architecture
With Virtual SAN, multiple ESXi hosts are grouped to form a Virtual SAN cluster.
Object-Based Storage
Virtual SAN stores and manages data in the form of flexible data containers called objects.
