VMware ESXi Deployment Examples

Single DataCore Server

A single virtual machine configured with virtual disks served over one or more iSCSI Loopback connections. A very reliable and extremely fast DataCore Caching as well as including the entire suite of DataCore Server features.

More physical DataCore Servers can be added to create a highly available configuration. See below.

A Pair of Highly-Available DataCore Servers

Two virtual machines configured with virtual disks served to the local ESXi Servers – ESXi A and ESXi B - over one or more iSCSI Loopback connections. The virtual disks are also as a synchronously mirrored between the DataCore servers using either iSCSI or Fibre Channel connections.

Each ESXi host’s VMkernel is configured to login to two separate iSCSI targets:

• The first path is connected to the local DataCore Server.
• The second path is connected to the remote DataCore Server.

For clarity, so as not to make the diagram too complicated, the example shows just one SANsymphony Front-end (FE) port per DataCore Server. Use more FE port connections to increase overall throughput.
