The CloudStack platform scales well into multiple sites through the use of zones. The following diagram shows an example of a multi-site deployment.

Data Center 1 houses the primary Management Server as well as zone 1. The MySQL database is replicated in real time to the secondary Management Server installation in Data Center 2.

This diagram illustrates a setup with a separate storage network. Each server has four NICs, two connected to pod-level network switches and two connected to storage network switches.

There are two ways to configure the storage network:

Bonded NIC and redundant switches can be deployed for NFS. In NFS deployments, redundant switches and bonded NICs still result in one network (one CIDR block+ default gateway address).

iSCSI can take advantage of two separate storage networks (two CIDR blocks each with its own default gateway). Multipath iSCSI client can failover and load balance between separate storage networks.

This diagram illustrates the differences between NIC bonding and Multipath I/O (MPIO). NIC bonding configuration involves only one network. MPIO involves two separate networks.
