AINS provided comprehensive support to HCFA in
migrating from a partial LAN (28 servers, 1200 users) environment,
spread across multiple locations, to a single facility with a fully
connected campus LAN incorporating 32 file servers (3000 users) in a
Novell NetWare environment. The physical topology used token-ring access
protocol with UTP (level 5) cabling. Campus connectivity was through
Synoptic Hubs and Routers connected to an FDDI fiber-optic backbone.
Principal technical support included:
- Technical analysis of existing Novell LANs and standalone workstations,
using Brightworks Fusion data-collection software, AINS-developed
utilities and user interviews
- Capture and analysis of network traffic baselines on existing Novell
LANs with Network General's Sniffer tool
- Design of ring and server logical and physical configurations for the
single-site Novell LANs
- Simulation of the network designs (with Optimal Network's Optimal
Performance software) using projected traffic loads to validate and
optimize configurations for supporting new users, applications, and
projected growth
- Assessments of LAN standards for network/workstation hardware/software
configurations, logical configurations, and network security
- Detailed implementation planning for 13 move increments (200 - 250
users) over a 16-week period
- Installation, upgrade, and burn-in of 32 file servers, including
installation of NetWare network-based applications, NetTune and
LANalyzer monitoring software and recovery of backed-up hard drives from
old servers
- Dual backups of existing servers prior to migration, including testing
of recovery procedures for backed-up files
- Test cabling and connectivity of all workstation drops to network
servers
- Establishment of new network performance baselines with network
monitoring tools (Sniffer, TrendTrak and LANalyzer)
- Documentation of all server and network configurations
Also provided comprehensive support in the preparation and migration of
workstations and related equipment to the new single-site facility,
including an interface with HCFA's Help Desk, equipment and software
inventory, and configuration management systems.
Key task areas included:
- Preparation of workstations to move to new LAN environment through
memory upgrades, Windows/software installations and NIC card
installation/replacement.
- Updating PC inventory and configuration management system at the
conclusion of all changes.
- Initializing trouble tickets (Infoman System) for each week's relocated
workstations prior to move and closing each ticket as workstations are
relocated and restored to full network connectivity with access to all
applications. Summarizing statistics of problem areas to assist in
planning subsequent moves.
- Securing and preparing HCFA's workstations and associated equipment for
safe transportation to the single site.
- Unpacking, reconnecting, and performing acceptance testing on relocated
microcomputers.
Developed a client/server prototype grant application and tracking
application as a demonstration project for HCFA, as they moved from
mainframe-based applications to a client/server environment. Key support
functions included:
- Database selection, design, and formal development with SQL*Server
- Front-end development with PowerBuilder
- Installation of Windows NT server
Supported HCFA's interconnectivity requirements through the installation
of communications servers, peripheral devices, and hardware/software
integration. Tasks included:
- Installation and testing of communication servers and software
- Device connectivity and cabling plant testing
- Installation and testing of mainframe connectivity software
