    VMware versions. Whats what.

    Hi.
    Does anyone know whats what when it comes to VMware?
    Reason being is that theres so many different versions its a little silly.

    For example, im running VMware Server v2.0 Free on one of our blades as a test thing, but i honestly cant see a single down downside to it. It supports 64bit, has no CPU/mem/HDD limits, or a limit on the number of VMs i can use.
    The only thing that its missing that i can see is that it doesnt do live VM migrations to another server.

    And ESXi, from what i can tell, is the same but its own OS/HyperVisor.
    Even the HP Insight 'version' is free.

    So what are the other VMware products, differences, and why would i need to pay for them?

    Thanks in advance all. .

    ESXi will have alot better perfomance than your VMware server, this is also free. The step up to cluster features and management will cost you tho....

    If you want 'live migration' with vmware you'd need a Vi3 licence enterprise licence for ESXi. You will also need a server (p or v) and vcenter licence to manage the ESX hosts.

    Vi3 Enterpise licence (HA, DRS, vMotion, vSmotion) is prety pricy even for education. The 'standard' Vi3 licence wont do live migrations (vMotion), but will quick migrate (pause->migrate->unpause). Standard doesnt have DRS (auto move VMs around hosts depending on workloads), however it does have HA (restart guest on another host if 1st host failed). Vi3 foudation also drops HA for just the basics.

    For all cluster features you'll need vcenter.

    If you have 3 hosts or under, you can get a vcenter 'foundation' that is quite abit cheaper.

    So basically:
    VMware Server - Free - Can do everything but migrations but needs a host OS.
    VMWare ESXi - Free - As above but is its own OS.
    VMWare ESX - As above but can do migrations.
    VMWare VI3 - As above but can do live migrations.

    ?

    Also look at Citrix's Xen offerings. They recently made a lot more stuff free to compete with VMware's free products and if you're just dipping your toes in the water may be a better option - live migration is free, for example.

    Sort of.

    ESX can do live migrations too, if you have the licence.

    Both ESX and ESXi can be used for the various Vi3 licences.
    You can't get hold of ESX without a Vi3 licence (you'll get ESX disks when you buy a Vi3 licence). You just happen to be able to download ESXi for free.

    The software difference between the two, ESX has a linux service console you can do tasks on, run cron jobs on. Some 3rd parts apps and plugins work with ESX but not ESXi. There is a hidden console in ESXi and RCLi but this is not supported by VMware yet.

    Vcenter server is needed for all cluster features. It handles the licenced features.

    So basically, if i have ESXi installed, then upgrading it to the more capable VMware products is simple a case of a licence key?

    Question: If i install ESXi now on one of our servers, then a few months down the line, install more RAM & a second processor, will ESXi pick up the extra resources automatically?

    Yeah. You just point the server to the licence server (usually the vcenter server) and it'll pickup whatever licences are available to the licence server.

    Yeah. Just remember the licences are per CPU (although sold in X2s).

    It'll do 4 cpus (not cores) out of the box (well download).

    I think this becomes 8 in the next release.

    When I mentioned the licencing I meant the Vi3 licenced features are per dual cpus (one copy of Vi3 per 2X cpu)... so I can run my 1 licence of enterprise Vi3 across two hosts because I only have 1 cpu in each. When the second cpu is installed it'll work out and grab both licences and moan that my second host doesnt have a licence (the rest of my licences are Vi3 std).

    Well ESXi is annoying me upto now.

    Aparentely its a 60 day trial! Thought it was free!
    And i cant find a way to import my old VMWare VMs.

    Im starting to think that i'd be better of using 2k8 & VMware server again...

    You need to get a licence key for esxi. It free. Look on the vmware website.

    You can import your old vm by copying the files to the datastore then right click on the vmx file and Add to inventory. You can use vmware converter as well.

    Dont panic. Its a 60 day trial with features you get with the Vi3 (paid for) licences. When the trial runs out, it'll still work.

    To import you cna do what andyrite said or can also use converter to move your VMs over.

    I have a licence though...? But everytime i go to register the key it wont register.


    Tbh, im failing to see the advantage over using a 2k8 based VMware installation.
    It wont support all the cores out of the box, and doesnt support any type of remote admin unless the client software is installed on the workstations you want to use to access it, ect;
    2008 is looking like the better option atm.

    Speed. No OS to manage.

    It does support the cores. It can do upto 4 P/CPUs per host.

    How would you access 2008? Some kind of remote software?

    OS to manage. I dont really have to 'manage' 2k8 though...occasional WU, but apart from that, nack all.

    It does support the cores.
    All 8 & all 16Gb of ram?

    How would you access 2008? Some kind of remote software?
    The VMWare Server (free), has a web interface for administration and used a Java based console screen.
    Does ESXi have anything like that? As i cant see nout...?
