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

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)

4. Scheduling


Slide30 l.jpg

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)

Slide32 l.jpg

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)


Slide33 l.jpg

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
