Primo #VMUGIT Hands-on Day: ExaGrid

23 Jan 2012 Leave a comment

Il 18 Gennaio, il primo VMUGIT Hands-on Day è diventto realtà! Protagonista di questo primo evento è stata ExaGrid  (rappresentata da Andy Palmer, EMEA Sales Director) e la sua soluzione di backup su disco.

L’ Hands-on day

L’Hands-On Lab è una giornata di laboratorio, in cui un singolo produttore ha la possibilità di presentare la propria soluzione e permettere ai partecipanti di testarla dal vivo.
Il taglio è spiccatamente tecnico, e la presenza di un unico produttore con un’unica soluzione, permette la partecipazione a persone realmente interessate all’argomento proposto.

L’evento è stato un successo: 16 partecipanti, parecchie domande, interazione tra partecipanti e vendor, molto interesse.

ExaGrid

ExaGrid è una società statunitense, fondata nel 2002 e con un unico prodotto a catalogo: l’appliance ExaGrid.

ExaGrid è una soluzione di backup su disco economica e scalabile che lavora in modo trasparente con le applicazioni di backup esistenti. L’approccio di ExaGrid minimizza la quantità di dati da salvare tramite compressione dei backup più recenti e deduplica dei dati byte-level di tutti i precedenti backup.

La demo

Ho registrato la prima demo. Eccola qui:

Tutte le demo sono state fatte su una appliance ExaGrid EX5000 presente in sala. Ecco un tour panoramico dell’appliance:

Arrivederci al prossimo evento del VMUGIT!

1st #VMUGIT Hands-on Day: ExaGrid

23 Jan 2012 Leave a comment

On January 18th, the 1st VMUGIT Hands-on Day has become reality! Main guest of this first meeting was ExaGrid  (represented by Andy Palmer, EMEA Sales Director) and it’s disk appliance backup solution.

The Hands-on day

Our idea for Hands-on day events, is to create a “day in a lab” where a single vendor can present its solution and allow participants to test it live. The main goal is to allow people genuinely interested in the solution proposed, to have a technical presentation and to have a technical contact with the vendor.

The event was a success! About 16 people attending the event, several questions and a lot of interaction between the vendor and the participants.

ExaGrid

ExaGrid is a US company, founded in 2002, that produce easy to use, plug-and-play disk backup and dedupe appliances.

The ExaGrid system is a scalable disk backup solution that works with existing backup applications. ExaGrid approach combines SATA drives, compression and byte-level data deduplication for fast and reliable backups and restores.

The demo

I’ve recorded the first demo. A note to my english speaking readers: the language used in the demo is Italian.

All the demos was performed on an EX5000 appliance. Here an overview.

See you at the next VMUG meeting!

vCenter Server Appliance: come registrare un vCenter nel vSphere Web Client via command line

16 Jan 2012 Leave a comment

image_thumb[1]

In vSphere 5 è presente un nuovo client web per gestire vSphere: il vSphere Web Client.

Prima di potersi connettere a un vCenter Server però, è necessario registrare il vCenter con il vSphere Web Client.

E’ possibile registrare più vCenter con un singolo vSphere Web Client ma il vSphere Web Client può connettersi a solo un vCenter Server alla volta, a meno che questi vCenter non siano uniti tramite Linked Mode.

Per registrare un vCenter è sufficiente aprire un browser e farlo puntare alla URL dei tool amministrativi: https://localhost:port/admin-app 

Se si sta usando il vCenter Server della vCenter Server Appliance, questo vCenter è preregistrato con il vSphere Web Client installato nell’appliance stessa.

Ma come fare se si vuole registrare un altro vCenter Server con il vSphere Web Client installato nella vCenter Server Appliance? Non è possibile registrare un vCenter tramite un client da un sistema remoto e non c’e’ nessun browser, ne’ grafico ne’ testuale, installato nella vCSA.

Per registrare il vCenter bisogna ricorrere a uno script via riga di comando, nascosto nella vCSA…

Ecco la procedura:

  1. Connettersi alla vCSA via ssh come utente root (il servizio ssh è abilitato di default)
  2. portarsi nella directory /usr/lib/vmware-vsphere-client/scripts:
    cd /usr/lib/vmware-vsphere-client/scripts
  3. Usare lo script admin-cmd.sh per registrare il vCenter:
    ./admin-cmd.sh register https://localhost:9433/vsphere-client https://localhost root <password>
  4.  

    Lo stesso comando puo’ anche essere usato per deregistrare un vCenter Server.

    Per completezza, ecco l’help completo:

    admin-cmd <register|unregister> <vSphere-web-client-url> <vCenter-server-url> <username> <password>

    register|unregister -  Tipo operazione. Se il tipo è register, questo tool registrerà il vCenter Server specificato con il vSphere Web Client. Se il tipo è unregister, questo tool deregistrerà il vCenter Server specificato.

    vSphere-web-client-url – vSphere Client URL. Esempio: https://clientIP:port/vsphere-client

    vCenter-server-url – vCenter Server che deve essere registrato o deregistrato.

vCenter Server Appliance: how to register a vCenter in vSphere Web Client by command line

16 Jan 2012 Leave a comment

With vSphere 5 there is a new web-oriented client to manage vSphere: the vSphere Web Client.

Before you can connect to a vCenter Server, you must register it with the vSphere Web Client.

You can register multiple vCenter Server systems with a single vSphere Web Client. However, the vSphere Web Client can connect only to one vCenter Server system at a time, unless those vCenter Server systems are joined together in Linked Mode.

To register a vCenter you just need to open a Web browser and enter the URL for the administration tool: https://localhost:port/admin-app 

If you are using the vCenter Server in a vCenter Server appliance, it is preregistered with the vSphere Web Client installed in the appliance.

But what if you want to register another vCenter Server with the vSphere Web Client installed as part of a vCenter Server Appliance? You cannot register a vCenter Server system with the client from a remote system and no web browser (neither graphical nor textual) is installed in the vCSA.

To register the vCenter Server you must use a command-line script, well hidden in the vCSA…

Here it is the procedure:

  1. Access the vcsa via ssh as root user (the ssh service is enabled by default on vCSA)
  2. Go to the directory /usr/lib/vmware-vsphere-client/scripts:
    cd /usr/lib/vmware-vsphere-client/scripts
  3. Use the admin-cmd.sh script to register the vcenter:
    ./admin-cmd.sh register https://localhost:9433/vsphere-client https://localhost root <password>
  4.  

    The same command can also be used to unregister a vCenter Server.

    For the sake of completeness the full usage is:

    admin-cmd <register|unregister> <vSphere-web-client-url> <vCenter-server-url> <username> <password>

    register|unregister -  Operation type. If the type is register, this tool will register the specified vCenter Server with the vSphere Web Client. If the type is unregister, this tool will unregister the specified vCenter Server.

    vSphere-web-client-url – vSphere Client URL. Example: https://clientIP:port/vsphere-client

    vCenter-server-url – vCenter Server system which is being registered or unregistered.
