Data ONTAP Fundamentals

Objectives

Upon completion of this module you will beable to: Describe hostname resolution as it applies to

storage appliances

Explain the limitations of using a filer as a router

Manage interface parameters on a storage

appliance

Describe the physical interfaces used by the filer

Create virtual interfaces (VLANs and VIFs) used bythe storage appliance


3/25

Hostname Resolution

/etc/hosts

A DNS server

A NIS server


4/25

Hostname Resolution


5/25

Hostname Resolution


6/25

Hostname Resolution

Domain

Controlleruser info

group info

7/25

Hostname Resolution


8/25

Storage Appliance is not a Router

The routing table display indicates the

available routes and their status. Each

route consists of a destination host or

network and a gateway to use in

forwarding packets.

Interface Names

The filer supports these network types: Ethernet 10/100BaseT

Gigabit Jumbo Frames supported in Data ONTAP 6.x, for filers with

Gigabit Ethernet Controller II interface FDDI

ATM

Interface names are based on: Network type Slot number

Port number, with multiport interface

Interface Names


14/25

The ifconfig Command

Network interface configuration parameters IP address

netmask address

broadcast address

mediatype, speed maximum transmission unit (MTU)

flow control (Gigabit Ethernet II controller only)

up or down state

Changes are not permanent until entered into

the /etc /r c file


15/25

Etherchannel Trunks (Virtual Interfaces)

What is a VIF? Aggregate multiple ethernet links into a single logical channel

between two devices

Clients access a single virtual IP address


16/25

Single-Mode Trunk


17/25

Multi-Mode Trunk


18/25

Load Balancing

Load Balancing is supported for multi-modeVIFs only IP-based (default)

MAC-based

Round-RobinNote: Load balancing assumes an even

distribution of IP addresses:e0 e1 e2 e3

10.10.10.9 10.10.10.10 10.10.10.11 10.10.10.12

Virtual Interface Commands

The filer supports trunking with virtualinterfacing vif create [single|multi] -b

[rr|ip|mac] []

vif delete [interface_list] vif destroy

vif add

vif [favor|nofavor]

vif status []

vif stat vif_name [interval]

The named virtual interface is treated as asingle interface: ifconfig vif_name


20/25

VLAN

(Virtual Local Area Network)

What is a VLAN?

What is VLAN tagging?

VLAN tagging in Data ONTAP

VLAN commands


21/25

VLANS


22/25

VLAN Tagging


23/25

A filer can have 128 interfaces This includes the vh, loopback, VIFs, ELAN,

Physical interfaces and VLAN IDs

Supported VLAN IDs are 1 - 4094 VLAN ID 1 is used by many switch vendors

VLANs over VIFs is supported

Commands are not persistent (need to be in

the /etc/rc file)

VLAN Tagging in Data ONTAP


24/25

VLAN Commands

VLAN commands vlan create g on

vlan delete [-q]

vlan add

vlan stat

vlan modify g [on|off]


25/25

Topic Review

How does a storage appliance resolvehostnames? /etc/hosts file, DNS, NIS

What are the limitations of using a storage

appliance as a router? A storage appliance is not a router

What does the ifconfig command display? Network interface information

What is a virtual interface? Aggregate of multiple Ethernet links

What is a VLAN? Virtual Local Area Network
