Before we show you the different components that are included in vSphere, note that it’s packaged in a few different ways.
For most enterprise deployments, vSphere comes in 3 different editions: Standard, Enterprise and Enterprise Plus. In each edition, the base product is the same, but Enterprise and Enterprise Plus provide additional components necessary for higher-end requirements.
For smaller deployments, vSphere also comes in Essentials and Essentials Plus Kits. These come with less components, but offer an attractive price point for smaller businesses. This module will focus on each of the three Editions.
3 Different vSphere Editions Product are listed below :
1. VMWare vSphere Standard
Thin Provisioning sets the minimum requirements for storage and then grows the storage over time, rather than allocating the maximum potential storage when configuring the application. Besides increasing storage capacity, it eliminates the need to keep a certain amount of space unused for future demands. With Thin Provisioning, the customer maximizes and extends the storage space they have.
Update Manager is an automated patch management solution that automatically applies security and bug fixes to vSphere hosts and their guest operating systems. Update Manager dramatically simplifies patch management, making sure that the datacenter has the patches it needs to protect against vulnerabilities.
When a host server fails, vSphere’s High Availability automatically restarts its virtual machines on other server hosts in the resource pool. This keeps downtime to a minimum and provides cost-effective high availability for all applications running in virtual machines.
vSphere Data Protection—otherwise known as VDP—is an entirely new backup and recovery solution included with vSphere 5.1.
VDP is very space efficient. A complex algorithm ensures a minimum amount of disk space is used by reducing ongoing backup storage growth. VDP also reduces the load on hosts and required bandwidth, because it sends only unique changes to minimize traffic.
vMotion allows you to effortlessly move virtual machines from one server host to another without any downtime. So if a customer is going to perform hardware maintenance on a server, or they see that a server is failing or underperforming, vMotion allows them to move virtual machines out from that server. The end-users won’t notice any delay or difference in their applications.
For smaller deployments, vMotion used to have one limitation. And that was that it required the use of shared storage, like a SAN or NAS. Now it is possible to move VMs using local storage instead. This helps customers meet service level goals with a less expensive storage infrastructure.
Hot Add allows the administrator to increase RAM and CPU resources to virtual machines as these resources are needed, without interruption to the VM. This reduces downtime and ensures that the applications in the virtual machines will always have the resources that they need.
vSphere’s Fault Tolerance is a feature that creates a live shadow instance of every virtual machine, keeping it in lockstep with the primary instance. This provides continuous availability to applications, preventing downtime and data loss in the event of server failures. It is also a simpler approach than traditional solutions like clustering or hardware redundancy.
Just like vMotion can move virtual machines from one physical server to another, Storage vMotion moves virtual machine storage from one storage array to another. It enables the migration of running virtual machines within and across shared storage locations. Storage vMotion brings the zero-downtime and continuous-service benefits of vMotion to storage arrays, allowing IT to more actively manage storage capacity and reduce I/O performance issues.
vSphere Replication has been designed to provide very cost-efficient, simple, yet powerful replication across sites. It tracks changed disk areas and only replicates the latest deltas to increase network efficiency. vSphere Replication also eliminates the need to have higher end storage arrays at both sites. For example, customers can have Tier 1 storage at the production site, but lower end storage at the failover site. And in addition to a disaster recovery focus, many customers have also found it useful for other purposes, like planned migrations.
vShield Endpoint strengthens security for virtual machines while improving performance for endpoint protection. vShield Endpoint offloads antivirus and anti-malware agent processing to a dedicated secure virtual appliance. This eliminates anti-virus “storms”, where many VMs are running anti-virus agents at the same time and streamlines antivirus and anti-malware deployment and monitoring. It’s also easier to satisfy compliance and audit requirements through logging of antivirus and anti-malware activities.
vShield Zones allow the customer to create trust zones that can isolate sensitive data and applications.
2. VMWare vSphere Enterprise
Virtual Serial Port Concentrator
The Virtual Serial Port Concentrator enables connections over the network to the serial port console on any server. By providing a way to remote a virtual machine’s serial port over a network connection, and by supporting a virtual serial port concentrator utility, vSphere gives administrators first-class support for the traditional server management approach.
Furthermore, these console connections are also considered more secure for virtual machines because the traffic is only on the management network.
Storage APIs for Array Integration, Multipathing
Storage APIs for Array Integration and Multipathing allow file-level backup support for Windows and Linux virtual machines, and they allow vSphere to integrate with the leading backup tools on the market today.
Distributed Resources Scheduler (DRS)
Also known as DRS, Distributed Resource Scheduler dynamically allocates and balances the resources of virtual machines according to pre-defined service levels and changing capacity needs. DRS leverages vMotion to migrate machines to different hosts when there is resource contention. The result: virtual machines with optimal access to resources and no downtime.
Distributed Power Management (DPM)
Distributed Power Management—also known as DPM—a component of DRS, continually monitors energy requirements in a VMware DRS cluster or resource pool. In periods of low usage, DPM consolidates workloads and powers down hosts to reduce power consumption. In periods of higher usage, it brings server hosts back online. The result is a significant cut in power and cooling costs for the datacenter.
3. VMWare vSphere Enterprise Plus
Distributed Switch is a centralized interface for all virtual machine networking in a vSphere environment. This interface simplifies the management of both the physical and virtual networks, and it forms the foundation for 3rd party virtual switches such as the Cisco Nexus 1000V. The Nexus 1000V provides Cisco networking features in a vSphere environment with features such as access control list, quality of service, and others. These advanced networking features enable the customer to accelerate server virtualization deployment.
I/O Controls (Network and Storage)
The Network and Storage I/O Controls allow the administrator to manage and automate the quality of service delivery when a virtual machine tries to access network resource or storage. Upon installation, the I/O controls create an equal priority for all virtual machines, and then the administrator can create rules that give priority for mission-critical VMs. Note that it is only when there is contention that specific VMs can be labeled VIPs and given priority.
Host Profiles and Auto Deploy
Auto Deploy and Host Profiles together form the method that vSphere uses to quickly deploy host servers across the cloud. The administrator uses Host Profiles as templates to configure the host servers and then Auto Deploy accesses those profiles to deploy these hosts.
No dedicated boot device, boot disk or install scripts are required, and a large number of hosts can be deployed within minutes. As a result, host server management becomes much simpler and faster.
Storage DRS automatically selects the best storage placement for your virtual machine, and then it will perform automated load-balancing based on space and I/O capacity. The operational overhead associated with provisioning virtual machines will be significantly less as a result. As mentioned earlier, DRS, or Distributed Resource Scheduler, balances the resources of the virtual machines according to services levels set by the administrator. Storage DRS accomplishes the same thing for storage.
