VMware infrastructure features The major advanced features:

Hardware level virtualization – no based operating system license is needed, ESXi installs right on your hardware (bare metal installation).

VMFS file system. SAN Support – connectivity to iSCSI and Fibre Channel (FC)

SAN storage, including features like boot from SAN Local SATA storage support. 64 bit guest OS support. Network Virtualization – virtual switches, virtual NICs, QoS & port

configuration policies, and VLAN. Enhanced virtual machine performance – virtual machines may

perform, in some cases, even better in a VM than on a physical server because of features like transparent page sharing and nested page table.

Virtual SMP – see advanced feature #4, below. Support for up to 64GB of RAM for VMs, up to 32 logical CPUs

and 256GB of RAM on the host.

12

VMware infrastructure features VM High Availability (VMHA)

With 2 ESX Servers, a SAN for shared storage, Virtual Center, and a VMHA license, if a single ESX Server fails, the virtual guests on that server will move over to the other server and restart, within seconds.

VMotion With VMotion, VM guests are able to move from one ESX Server

to another with no downtime for the users. VMware Consolidated Backup (VCB)

VMware Consolidated Backup (or VCB) is a group of Windows command line utilities, installed on a Windows system, that has SAN connectivity to the ESX Server VMFS file system. With VCB, file level or image level backups and restores of the VM guests can be performed, back to the VCB server.

Concluding remarks System is implemented on two x3550 servers

equipped by data storage system

VMware “bare metal virtualization” was used

Moodle as a LMS was employed
