Section 12 Storage Area Network SAN Networking
3BSE056141-510 F 113
One or more ESX(i) servers are connected to multiple network switches through
multiple network connections. The SAN server is also connected to the switches
through multiple network connections.
There are two types of network traffic in this configuration. One is for access to the
shared storage through iSCSI. The other is for configuration and management of the
servers. To provide security and reliability, the two types of traffic are separated
using a VLAN.
To reduce single point of failures, separate network adapters should be used in the
ESX(i) servers for the storage network as shown in the Figure 37.
While the multiple network connections provide redundancy, it also provides load
balancing. Figure 38 provides an example of IP addresses for the storage
network.
When configuring the IP addresses in the SAN server, the VLAN settings may be in
the advanced settings as shown in the Figure 39.
In the Figure 40, it is observed that the SAN server does not support VLAN. In this
case, separate network switches for iSCSI and management traffic should be
used.
