In a previous post I introduced StorMagic SvSAN and talked about its main features and components.
In this one I’ll take a look at the installation process.
Firstly download the latest SvSAN software, currently version 5.3.3461.
On the vCenter Server double click setup.exe, in this case I’m missing a prerequisite and the installer will take care of it.
Select Custom to be able to choose which features to install.
Deploying SvSAN in a vSphere environment I excluded the Hyper-V Deploy Wizard, installing instead the quorum service and the vCenter Server plug-in.
Provide vCenter Server administrative credentials.
Check the new StorMagic Windows services.
Before start deploying the VSAs the ESXi nodes must be configured.
The underlying raid controller must be prepared specifying a minimum of two LUNs, a smaller one where to deploy the StorMagic VSA, 30 GB are more than enough, and another one to use as storage space.
Assuming the nodes have two dual port nic, connect a port per nic to the production switch and the other two directly.
On the ESXi nodes perform the following steps:
- create two additional vSwitches
- for each vSwitch, create a VMkernel interface and a Virtual Machine port group
- enable the iSCSI software storage adapter
- perform iSCSI optimizations
The ESXi node networking will look like this.
Time to deploy the StorMagic VSAs, using the vSphere Web Client (preferable) or deploying an OVF file.
Select the Datacenter, Manage, StorMagic and click Deploy a VSA onto a host.
Select the first ESXi host, the procedure will be applied again using the second host, specifying the root password.
Set the VSA hostname, the dns suffix and the datastore to use.
Click Add to manage the storage settings.
Create a Storage Pool selecting the LUN to access via Raw Device Mapping.
If present, a device can be selected as caching storage.
Select how to use the VSA interfaces, in this deployment we have three networks, one for management (vSwitch0) and two used for StorMagic iSCSI,Mirroring (vSwitch1 and vSwitch2).
Apply the configuration for each each network.
Enter the product key here or later via web console.
Enter the password for the VSA.
Click Finish to start the deployment.
When the deployment completes, make a rescan of the iSCSI Software adapter and the StorMagic device will be available to be used creating a datastore.
Stay tuned for the next post, I’ll take a look at the web console and the StorMagic configuration settings.
