ERA SAN Environment2001Current Disk Space

• New environment currently has one cabinet with
  two HSG80 storage arrays.
• With a combination of 18GB and 36GB drives we
  have approximately 3.9 terabytes, of
  whichbecause of RAID configurationsapproximately
  2.2 terabytes are usable disk space.

ERA SAN Environment2002Additional Hardware and
Disk Space

• One additional cabinet with two HSG80 storage
  arrays has been ordered, in addition to 26 72GB
  drives.
• The total disk space will be increased to 5.7
  terabytes.
• Usable additional space will depend on filesystem
  RAID configuration.

ERA SAN Environment2002Total Possible Disk
Space Capacity

• The SAN will have approximately160 empty slots
  across the four HGS80 storage arrays.
• Depending on disk size application requirements,
  if SAN is filled to capacity, it will have a
  minimum additional 2.8 terabytes (all 18GB
  drives) to a maximum additional 11 terabytes (all
  72GB drives).
• Usable space will depend on filesystem size
  requirements and RAID configuration.

Progress on Database Migrationsto the New
EnvironmentPart 1

• Development, Test Training Migrated To ES40-SAN
  (Cathy, Nora, Ramesh, Xiaoping, Lhadj)
•  Installed Oracle v8.1.7.2.1 running under Compaq
  TruCluster 64 Unix v5.1 (Xiaoping, Lhadj)
•  Firewall Access Rules implemented on 12/10/01
  CIT OPS
•  Testing of access via client-server apps, web
  apps and reporting apps to commence on 12/11/01
• All Databases functional and operational.
• Development, Test and Training Summary Statements
  and

Progress on Database Migrationsto the New
EnvironmentPart 2

• Hardware configuration and tests on the GS160-San
  completed. (Cathy, Nora, Mike, COMPAQ)
• Production IMPACII (impprd) and IRDB (irdbprd)
  migrated to new GS160-San environment on a trial
  basis. (Ramesh, Lhadj, Xiaoping)
• Migration accommodated into enhanced directory
  structure for the database datafiles (Ramesh).
• Clonset of IMPACII and IRDB taken and all
  database datafiles copied (migrated) to the new
  GS160-SAN. Both databases are functional and
  operational. (Ramesh, Lhadj)
• Database scripts and crontabs (cronjobs) being
  migrated. (Xiaoping)
• Bridge(s) being set up and tested (Barbara)
• Firewall Access Rules implemented on 12/10/01
  CIT OPS.
• Reports Server Web Application Server
  configuration
• To be completed and opened up to testers on
  12/11/01 (Ramesh, Ranvir, Mike)
• Testing of Backups, Oracle Enterprise Manager and
  BFILE Index Creation ongoing (John)
• Oracle tnsnames connectivity configuration across
  middle tier servers to be completed 12/11/01
  (Ramesh, Ranvir).
• Summary Statements and Grant Images scheduled to
  be Copied on 12/11/01 (Nora)
• Open GS160-San environment to testers on 12/12/01
