HP LeftHand SAN Solutions Support Document - Service Notes - VSA 7.0 for VMware ESX

Table 1 lists the expected flow control settings for various types of NIC bonds.

The flow control setting should remain the same after you create any bond. If

you check the NIC bond and find that the settings are not the same, delete the

bond and reset the flow control settings to ensure that they are the same.

Configuring The SAN On A Private versus Public Network (3836)

Best Practice

The recommended best practice is to isolate the SAN, including Console

traffic, on a separate network. If the SAN must run on a public network, use a

VPN to secure data and Console traffic.

Storage Traffic Is Using The Wrong Network Interface Card (NIC) (5168)

Scenario

You may see SAN/iQ traffic on NICs other than the designated one.

Explanation

This is unavoidable when two or more NICs are assigned IP addresses in the

same subnet. It can occur in any configuration where hosts are configured

with multiple NICs.
