Network cable requirements
The customer is responsible for supplying cables that connect to the patch panel,
including host attachment (Fibre Channel or iSCSI) cables, management cables,
maintenance cables, and virtual private network (VPN) cables.
Table 26. Required cable types
Cables Required cable type
Fibre Channel 50 µm (micrometer) multimode Fibre Channel cables with
LC/LC or LC/SC connectors (if applicable).
Note:
If you require 62.5-µm fibers, contact an IBM service
representative for assistance.
Ethernet (iSCSI) 50 µm (micrometer) multimode optical cables with LC/LC
or LC/SC connectors.
Management Straight copper gigabit CAT5e-rated Ethernet cables with
RJ-45 connectors.
Virtual private network
(VPN) Straight copper CAT5e-rated Ethernet cables with RJ-45
connectors.
Network and host connectivity security information
The storage system integrates various security features, to protect your network
and host systems.
Use this information to help understand and plan for network and host
connectivity security for your IBM FlashSystem A9000R storage system.
IPv6 addresses
IPv6 addressing for IBM FlashSystem A9000R management and virtual private
network (VPN) ports is supported throughout the storage system.
IPv6 addressing can be configured during initial system setup, by your IBM service
provider, or at any time using the IBM Hyper-Scale Manager UI or XCLI utility.
Note: For configuring IPv6 during initial setup, be sure to give all information to
your SSR/IPR, to fill in IPv6 details in your Technical and Delivery Assessment
(TDA) pre-installation checklist and worksheets.
Internet Protocol Security (IPSec)
Internet Protocol Security (IPSec) is a protocol suite that allows for enhanced
security of IP communications through the authentication and encryption of IP
packets.
The IBM FlashSystem A9000R system software and IBM management tools allow
for the use of passkey or certificate authentication to establish IPSec connectivity
between management workstations and the management or VPN ports of the
storage system.
Configuration of the IPSec is done through the command-line interface (CLI). For
IPSec configuration, see the IBM FlashSystem A9000R Command-Line Interface (CLI)
Reference Guide, SC27-8711on the IBM FlashSystem A9000R Knowledge Center
website (ibm.com/support/knowledgecenter/STJKN5).
