0.Introduction(2)• Terminology(Not accurate :p) HV Hyper Visor VM Virtual Machine Famous “Virtualization” American company. VMware Consumer Products: VMware Player/Fusion HV provided by VMware. ESXi (1) Free version -stand alone- (2) Paid version - can be controlled by vCenter vCenter Server to control multiple ESXis Set of ESXis controlled by vCenter Cluster HA function is configured on each Cluster. To move VM from one ESXi to another ESXi. vMotion i.e. use for ESXi hardware maintenance High Availability. Automatic VM restart on the HA other ESXi in case of ESXi failure.
1.Today’s topic• Let’s have fun with creating “home cloud”. • AWS/VMware Player is very cheap and useful but lets try & feel “physical cloud” at home.• But we have NO MONEY... have only one server;) • Keep in your mind we live in “Virtualization” IT world.• Can we use virtual ESXi ? YES, WE CAN! • “nested ESXi” means “ESXi(VM) on ESXi(HV)”. • We can use vCenter to control “ESXi”s on ESXi.
2.Requirements(1)• Hardware • At least one x86 server. • CPU is key(VT-x:mandatory. EPT:optional). • Sufficient Memory • My case: Dell PowerEdge1950(2nd hand) • Storage for HA • NFS or iSCSI • My case: QNAP TS-119P II + Sata disk
2.Requirements(2)• Software • Get VMware account(free) and download: • Standalone ESXi HV(free) • vSphere 5.1 Evaluation(60 days) • vCenter Evaluation Appliance(60 days) • Client OS media for test • Linux, Windows
3.Design(1)• Image RDP,ssh Physical Server vCenter ESXi ESXi Storage
3.Design(2)• Goal: to execute VMotion & HA RDP,ssh Physical Server vCenter ESXi ESXi Storage
4.Installation(1)• Points • ESXi(VM)’s Machine Type: 9 (vmx-09) • vhv.enable = TRUE (in case of EPT enabled) • NWs on ESXi(HV) set to “promiscuous” mode • Dedicated NW for vMotion • Multiple management NWs for HA • vCenter Appliance: vmware/vmware
