2. Preparation for Migrating to a New Server 1. Capacity Planning for Server 2. Server Setup / Configuration 3. Innovative’s Access 4. Scheduling 5. Migrating to a New Server 6. Testing with Post-Event Checklist

4. 1. Capacity Planning for Server

5. 1. Capacity Planning for Server (By Administrator) • Estimate Current Resource Utilization • Define & Analyse Requirements • Size the New Server

6. 1. Capacity Planning for Server • Estimate Current Resource Utilization • CPU Usage • Memory Usage • Disk Usage • Current workload

7. CPU Usage - Memory Usage - Current workload #top

8. Disk Usage #df

9. 1. Capacity Planning for Server • Define & Analyse Requirements (Example) • CPU requirements (OS + Application S/W + No.of user) • Memory requirements (OS + Application S/W + No.of user) • Disk requirements (OS + Application S/W + No.of user + Data) • Backup system • Future requirements (CPU + Memory + Disk) • Placement (Cabinet) • Redundant Power Supply • UPS (Uninterruptible power supply ) • Maintenance Costs

10. OS CPU RAM Application Software Users Harddisk

11. Tape Backup

12. Tower Server Rack Server Cabinet Harddisk UPS Redundant Power Supply

13. 1. Capacity Planning for Server • Size the New Server • Data available from Vendors

14. Processors Memory Operating Systemfrom Factory Support OS

15. http://www.redhat.com

16. Storage Type Maximum Storage RAID Controller( RAID 5, 1, 0, 0+1, 1+0 , etc.)

17. Network Interface Card

18. Redundant Power Supply

19. 2. Server Setup / Configuration

20. 2. Server Setup / Configuration Create Linux Partition (ext3 file systems) (By Administrator) root: minimum 500 megabytes usr: minimum 2 gigabytes swap: minimum 2x the amount of RAM (i.e. 128 MB RAM = 256 MB swap) iii: minimum 2 gigabytes (10gb is plenty) iiidb/software: minimum 12 gigabytes (30gb is plenty) iiidb: remaining diskspace (largest amount of disk space)

22. 2. Server Setup / Configuration Install Applications Software (By Administrator + Innovative)

23. 1. M > MANAGEMENT information 2. I > INFORMATION about the system 3. F > FILE information

24. 2. Server Setup / Configuration Install Applications Software (continued) (Administrator) • OS installed in 32 bit mode • C Compiler / Debugger (Administrator) ‘gcc’ software • SAR (system activity reporter) (Administrator) ‘sysstat’ software • Compress Utility (Administrator) ‘ncompress’ software (not bzip / gzip / tar !!) (Administrator) • ‘Rsync’ software • Correct Time Zone (Administrator) • Powerwatch (Innovative)

25. 3. Innovative’s Access

26. 3. Innovative’s Access • Secure Shell (SSH) access is granted through sites firewall • both of new and existing server (Administrator) • Login setup with "system" level privileges as well as • the "root" password (Administrator) (Administrator) • Accounts are not "iii" nor "iiiroot" • Accounts are available not less than 10 working days before the actual migration (Administrator)

27. 3. Innovative’s Access • Access Through Local Firewalls What network access through firewall does Innovative need? Support from Emeryville, CA, USA 205.227.88.253 In addition, Innovative requests that access be granted through your firewall for both inbound and outbound Secure Shell (SSH)andFTP services for the IP address listed below. 8.4.224.250

28. Existing Server-RHAS 2.1 New Server-RHEN 4.7 rsync Swap IP /Hostname Server Firewall Server Firewall SSH / FTP Innovative Computing CenterFirewall 205.227.88.253 8.4.224.250

29. 4. Scheduling

30. 4. Scheduling (Administrator) • Dates for migration (upon the library) • Migrations are performed during Innovative's core business hours (M-F, 8am-5pm Pacific time(US) GMT-08:00 ) Bangkok - GMT+07:00 Once both sides have agreed on a date to perform the migration, will also need the following: • Five working days before actual migration, please start • announcing to your patrons that the Innovative Server will • be inaccessible for 24 hours (Administrator)

31. http://wwp.greenwichmeantime.com

32. 4. Scheduling • Perform a Full Backup at close of business the night before • the migration takes place (Administrator) • Have one staff person available during the migration in case • of an emergency (Administrator) • Full testing of the system should be done RIGHT AWAY • following the migration (Staffs in each module)

33. 4. Scheduling • Current system must be running Innovative's latest supported • release of software (Administrator) • Prepare to swap IPs and hostnames after migrated your data • to the NEW server (Administrator)
