Changing the Client Network Bonding Mode
Change the bonding mode (Adaptive Load Balancing or Link Aggregation Control Protocol) of the client
network interface to match your environment.
• If using ALB, use one client VIP per client port in the FluidFS cluster.
• If using LACP, use one client VIP per NAS controller in the FluidFS cluster.
1. Click the Performance & Connectivity tab on the left.
2. Click the Client Network & Time tab on the top.
3. In the Client Interface pane, click .
4. Click Modify Settings.
The Modify Client Interface Settings dialog box appears.
5. Click the radio button next to the desired option:
– Without link aggregation
– With link aggregation (IEEE 802.1ax), also known as dynamic 802.3ad or LACP
6. Click OK.
Managing SAN Fabrics
SAN subnets or "fabrics" are the network connections between NAS controllers and PowerVault MD
controllers. In PowerVault systems, the SAN network consists of multiple subnets called SAN, SANb,
SANc, etc.
The number of SAN fabrics depends on the number of SAN ports available on the PowerVault NAS
controllers, and MD controller ports assigned to FluidFS/NAS. The general recommendation is to assign 2
ports on each MD controller to NAS traffic, so the number of SAN subnets are also 2.
The following table summarizes the type and number of physical ports on each type of FluidFS controller:
PowerVault FluidFS Controller
SAN ports Type SAN ports
NX3500 1GbE eth30, eth31
NX3600 1GbE eth30, eth31, eth32, eth33
NX3610 10GbE eth30, eth31
As a rule:
• Each NAS Controller should have a SAN NIC and an IP address assigned to each subnet: eth30 on
SAN, eth31 on SANb, and so on.
• Each MD controller should have a port and an iSCSI Portal address assigned to each subnet.
The following table summarizes the typical configuration of a system with 2 NAS controllers and 2 MD
controllers:
Subnet/Fabric
NAS Controller0 NAS Controller1 MD Array
SAN eth30:<IP> eth30: <IP> port0, <Portal IP>
SANb eth31:<IP> eth31:<IP> port1, <Portal IP>
The netmask and MTU on all subnets must be identical on all FluidFS and MD controller ports.
