  1. Document Overview

1.1Introduction

This appendixdescribes Eskom’s Baseline infrastructure landscape i.e. current traditional IT (as-is) infrastructure landscape.

1.2Document Purpose

Eskom’s baseline infrastructure as well as the required services to operationally support the infrastructure must be taken over by the selected Tenderer/s and offered back as a service to Eskom.

1.3Baseline Information

The current Traditional IT (as-is) infrastructure landscape is described below.

1.3.1Data Centres

Eskom’s IT Infrastructure is hosted mainly in its regional Data Centres however some infrastructure is hosted in server rooms at power stations and corporate offices. The Data Centresthat form part of the Regional sites are listed below:

# / Name / Physical Address
1 / Bellville / 60 Voortrekker Road, Basement Floor,Eskom Building, Bellville, 7530
2 / Bloemfontein / 1st floor Eskom Centre, 120 Henry Street, Westdene, Bloemfontein, 9301
3 / Brackenfell / Eskom Road, Brackenfell
4 / Duvha / Duvha P/Station, Bethal Road, Witbank, 1034
5 / DuvhaStabnac / SOC Duvha, Duvha Power station, Bethal Road, Witbank
6 / East London / Eskom SOC, Cnr Bonza Bay Road & Quenera Drive, Beacon Bay, East London, 5241
7 / Enterprise Park / Sunilaws Office Park, C/R Quenera Drive & Bonza Bay Road, Beacon Bay, 5241
9 / Mkondeni / 1 Portland Road, Mkondeni
11 / Polokwane / 30 Hans van Rensburg street, Polokwane, 0700
12 / Rosherville / Lower Germiston Rd, Rosherville, 2002
13 / Sanhill / Eglin Road, Sunninghill
14 / Simmerpan - Distribution / Cnr.Power Refinery RD Germiston
15 / Simmerpan - Transmission / 3d Floor core, ESKOM National Control Building, Simmerpan, Cnr of Lake(called Refinery on some maps) and Power street, Germiston
16 / Witbank / CnrWatermeyer & Jellicoe Street, Eskom Park, Witbank, 1035

Table1: Eskom Site List

Currently the Network latency between Eskom sites does not support a synchronous data replication method. However, the Tenderer/s need to indicate if the Network latency is resolved that they can design for data to be replicated synchronously.

For the Hosted Private IaaS the Tenderer/s Data Centre sites must be within the borders of South Africaand the Tenderer/s needs to implement a synchronous data replication method to replicate the data between sites.

1.3.2Network

With respect to connectivity between the Cloud Service Provider and the Eskom Network, all network connections into the Eskom Network will be established via a vendor neutral side. Eskom will extend its network to the vendor neutral side and connectivity from the Cloud Service Provider to the vendor neutral site must be provided and managed by the Cloud Service Provider. Connectivity from the vendor neutral site to Eskom will be provided and managed by Eskom.

The network design must include security devices (e.g. Firewalls, etc.) and software to enable connection to Eskom internal systems for integration purposes. The Tenderer/s will also be responsible for Network security;therefore, it is required that the Tenderer/s has a SOC (Security Operations Centre).

1.3.3Backups

Figure 1: Backup Infrastructure Landscape

Device Description / Quantity / Applicable Sites
Media Server Duplication Pool (MSDP) / 33 / All Power Station
Media Servers- x86 / 36 / Both Central and Regional(7 Traditional DX Sites)
Master servers – x86 / 12 / Both Central and Regional(7 Traditional DX Sites)
Backup Storage – Quantum + HP / 28 / Both Central and Regional(7 Traditional DX Sites)

Table 2: Backup Infrastructure

The Tenderer/s will be responsible for the implementation of backup and recovery solution as well as the maintenance and support of the backup services.

Backup schedule required:

Table 3: Backup Schedule

1.3.4Storage

Eskom leverages on its Enterprise Storage environment for all storage requirements. Depending on the requirements of the application/solution different tiers of storage gets allocated as depicted below.

The Tenderer/s will be responsible for providing/provisioning storage for all application environments in the landscape.

1.3.5Server Infrastructure Landscape

Eskom’s current server infrastructure landscape is described below.

The Tenderer/s is expected to perform the following general responsibilities:

  • Server provisioning activities;
  • Server operations activities; and
  • Server change management activities.

Server Infrastructure Overview:

  • Eskom uses physical and virtual servers based on Windows, Linux or UNIX both in stand-alone and in cluster configurations and requires three possible levels of services: Standard (99% availability), Advanced (99.9% availability) and Premium (99.97% availability).
  • The Tenderer/s should have skills in the following technology areas to support Eskom’s Servers (including but not limited to):
  • Operating Systems (including associated cluster software):
  • Windows Server
  • Linux (e.g., SUSE, Red Hat, Oracle-Linux, etc.)
  • UNIX (e.g., AIX, HP-UX, Solaris, etc.)
  • Hypervisors:
  • VMware
  • Power VM
  • Replication Software:
  • SRM
  • Platespin
