Once you have downloaded Visto One, Virsto One is installed into the parent partition of Microsoft Hyper-V.  Virsto One has a simple install wizard to walk you through the configuration steps.

If you have a multiple node cluster, do you install Virsto One in each host?

In short, yes.  Each Hyper-V server that wants to access the Virsto shared storage needs to install Virsto One.

A little more detail: One node in the cluster is designated the Master.  This is where all storage configuration is performed.  You perform a full <Typical> install on the master Node.  On all other servers, you then use the custom option in the install wizard to remove the master service from the core install.  This effectively installs only the Node service on the other nodes in the cluster. 

Remember, you need to provide a separate Log Volume for each node in the Virsto cluster configuration.  When you enter the GUI for the first time (on the Master) you must use the <Configure> options from the right column to designate your Log and Live Volumes.  The GUI only lets you add 1 log volume at a time.

Note:
The Logs are automatically allocated to the other nodes. 
The GUI can be installed and run remotely on any Hyper-V or Windows 7 machine on your network.

One log volume per host? The log volume need be RAID1 or RAID5 protected? That may take quite a lot of disk spindles for the whole cluster.

Hi Tina,
Great Question.  You are correct, 1 log volume per host, however that does not have to be a lot of spindles.  For example: RAID 1 built using 2X500G disks. Creating 20G LOG volumes would support 25 nodes. 

How many nodes in your cluster?
What is your storage configuration?

10 servers in iSCSI SAN.
NTFS format for existing RAID.
Do I need migrate all data if current system moves to Virsto?
BTW, no eval copy can be downloaded yet. Is there any chance to get one copy soon for evaluating how it’s going to impact existing system?

Hello Tina,

There are many things to consider but in general, you would migrate/import all the data/VHD’s that you want to optimize on the our vitural storage.  This can be done in stages or all at once depending on your excess capacity.  You may find that you don’t need to import all VM’s as they can be re-cloned once you import the golden master.

Best that we get you an eval copy and you can setup your testing environment.  When you are ready, we can help you come up with a migration strategy.  Please click the link on our homepage to get started with your Eval or use this:
