IBM ESS 3000, Hardware Planning And Installation Manual

Page: 75 / 108

Appendix A. Planning worksheets (customer task)
Customers are responsible for completing the system planning worksheets.
The customer then provides the worksheets to the IBM SSR when they install and configure the system.
Installation worksheet
This worksheet is intended for customers as part of the TDA process to outline the items required to be
implemented by the SSR during setup.
Customer task
Customer fills out the desired IP addresses.
SSR task
The SSR uses this information to properly set the desired IP addresses on each canister and the EMS (if
applicable).
Note: The management IPs should be on the same subnet as the EMS bridge interface. If you already
have an existing EMS, set IP addresses on the same subnet (all must be reachable).
Note: This document does not describe about the high-speed network. Customers must have that in
place and ready to fill in (or update) the /etc/hosts file on the EMS node during the software
installation. For reference, see Chapter 4, “Installing,” on page 39 and IBM Elastic Storage System 3000
Quick Deployment Guide. The high-speed interfaces are on a separate switch and should be defined on a
different subnet.
• For instance, if your management interfaces are all 192.168.45.X/24, your high-speed hosts should be
any other network. For instance, 172.16.0.0/24. You should use /24 (255.255.255.0), if possible.
Prerequisite (for SSR): You must be connected to the SSR access port of the target canister (top or
bottom). See the “Elastic Storage System 3000 installation (SSR task)” on page 51 for steps required to
check the hardware and set the desired IP addresses outlined in this worksheet by the customer.
