Introduction

• Cabling is a key section of this training course.
• It is important to understand the cabling of the
  SharedStorage in order to know how to
  troubleshoot problems.
• Additionally, if a customer ever re-configures a
  SharedStorage system, you will need to know the
  correct cabling connections in order to restore
  proper configuration.

Introduction

• Module objectives
• At the end of this module, you will be able to do
  the following
• Describe and identify the proper cabling
  connections from the
• disk shelf to the loop switch
• Describe and identify the proper cabling
  connections from the
• filer to the loop switch
• Describe the nomenclature plan used to identify
  the connection
• ends of the SharedStorage cables

Disk Shelf to Loop Switch Cabling
SharedStorage systems can have up to four nodes.
The diagram below shows a graphic representation
of four nodes cabled together. Click the forward
arrow to proceed.

Disk Shelf to Loop Switch Cabling
The following diagram shows cabling from a disk
shelf to both loop switches in one node. Click
the forward arrow to proceed.
Node 1

• Each disk shelf is connected to two separate
  loop switches, A and B via all-optical
  cabling.
• Each shelf in the loop must have a unique shelf
  ID (1 to 6), just as in normal filer
  configurations.
• There are no daisy-chained components for best
  performance and resiliency.
• Enable the terminator on each ESH module.
• ESH2 has auto-termination.

Disk Shelf to Loop Switch Cabling

• It is important to access the SharedStorage
  Cabling Guide PDF document
• on the NOW web site.
• The guide is located in the Hardware Library
  link, under SharedStorage, which is
• http//now.netapp.com/NOW/knowledge/docs/hardw
  are/hardware_index.shtml.
• Each set of shelves requires two loop switches,
  one for the A loop and one for the B loop.
• Begin by attaching the A ESH modules on
  shelves 16 to the A switch ports 1116.
• Then attach the B ESH modules on shelves 16
  to the B switch ports 1116.
• Repeat for each set of shelves in the other
  storage nodes.
• The animated diagram on the following screen
  illustrates the cable connections.
• Click the forward arrow to proceed.

Filer to Loop Switch Cabling

• Now we will look at the cabling between the filer
  and the loop switch.
• A cable harness is used when the equipment and
  nodes are located in adjacent cabinets.
• Open cabling is used when the harness cannot be
  installed due to distance requirements or when
  the equipment and nodes are located in racks.
• Follow the SharedStorage Cabling Guide on the
  NOW site to insure that
• No set of shelves uses the same adapter for both
  the A and B connections
• Each filer is connected to all loop switches (
  2, 4, 6 or 8 depending on system size)
• Each filer has two paths, A and B to each
  disk shelf
• Click the forward arrow to proceed.

Cabling Nomenclature
The cable harness and SharedStorage Cabling Guide
(available on NOW site) use the following
nomenclature
A or B port number
n_from
n_to
switch

Cabling Nomenclature

• Some further nomenclature information includes
  the following
• Important In the Network Appliance cabling
  convention, filer 1 always connects to port 1 on
  a loop switch, filer 2 uses port 2, and so on.
• The use of this same nomenclature scheme when
  labeling an open cabled system will facilitate
  troubleshooting.
• The photo illustrates how the ends of the cable
  connectors should be labeled to identify origin
  and termination points.
• The label will read the same at both
• ends of any cable.
