CHAPTER 2 Getting Started

Pre-installation Planning

Before installing Juniper Networks software, ensure that your hardware meets these conditions:
•
Running optimally (all hardware diagnostics have been run and passed successfully).
•
All data is backed up; Juniper Networks Media Flow Controller completely format all disks
when installed.
•
Top-quality cables are used. We recommend CAT5e or CAT6 for GbE, CAT6A for 10GbE,
or Fiber LL cables. However, CAT5 cables can be used for GbE if the cable lengths are
expected to be short ( for example, 5 feet or less). A poorly functioning cable can inhibit
performance.
•
NIC is present.
•
Console server / terminal server are available (recommended).

Tip!
You also need to know:
•
Which physical ports you want named eth0 and eth1. This is important because eth0
(management interface) and eth1 (recommended origin-fetch interface) are usually NOT
automatically assigned to the optimal ports (non-traffic bearing); instead, you must make
this assignment as part of the installation.
•
Hostnames/IP addresses (including but not limited to, Subnet Mask, Default Gateway) for
traffic and management ports.
•
Hostnames/IP addresses for external servers such as origin servers/libraries, DNS, NTP,
logging, or storage servers.
Important!

Release Installation Guidelines

This section provides information on the way Media Flow Controller works with Host Bus
Adapters/Hard Drive Controllers.

Host Bus Adapter / Hard Drive Controller

Media Flow Controller does not natively support RAID of any kind on any hard drive or
combination of hard drives. We recommend that ALL hard disk drives (HDDs) are configured
in "Just a Bunch of Disks" (JBOD) mode with write-cache disabled, regardless of controller
battery.
At initialization, Media Flow Controller attempts to uniquely identify each HDD by its
manufacturer-given serial number. This allows caches, the physical disks to which Media Flow
Controller writes cached data, to be removed and reinserted into a system without data loss or
the need to re-initialize. Also, because Media Flow Controller is able to uniquely identify
caches, they may be transferred to to another Media Flow Controller (removed from one
physical server and inserted in another running the same version of Media Flow Controller).
This lets you hot-swap caches for either new HDDs (provided the controller supports
hot-swap) or existing caches—without interrupting content delivery or restarting Media Flow
Controller.
