Deploying and Managing Virtual Storage Appliances

Before you deploy VSAs, verify that your system meets the following requirements:

• Configure vSwitch1 and vSwitch2, with one VMkernel port for SAN connectivity configured for the vCenter iSCSI software

adapter.

• If you are using RDMs to assign storage, enable SSH on the host. However, SSH needs to be enabled only for the duration

of the deployment of the VSA. You can disable it immediately after deployment is complete.

• Add the virtual disk that was created for the SvSAN VSA virtual machines in ESXi and create a VMFS data store.

• Enable the iSCSI software initiator on ESXi hosts.

• Enable the iSCSI port (TCP port 3260) on the VMware firewall.

A typical SvSAN environment consists of two hypervisor hosts. You can deploy a VSA by using the plug-in. You can install a
VSA on each host in a data store residing on server internal or direct-attached storage. A 512-MB boot disk is required along
with a 20-GB disk for storing metadata. Any additional internal or direct-attached storage assigned to the SvSAN VSA is used
to create synchronously mirrored volumes. The VSA requires a CPU reservation of 2 GHz and a memory reservation of 1 GB.

Deploy a VSA to a Host

Repeat the following steps for each VSA to be deployed.
1. Open the plug-in: in vSphere Web Client, select your data center and then navigate to

Manage > StorMagic (Figure 30).
