## ERA Ultimate Production and Development Environment

## ERA SAN Environment—2002Clusters and SAN

## ERA SAN Environment—2001Current 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 which—because of RAID configurations—approximately 2.2 terabytes are usable disk space.

## ERA SAN Environment—2001 HSG80 Cabinet 1 – Controller 1

## ERA SAN Environment—2001 HSG80 Cabinet 1 – Controller 2

## ERA SAN Environment—2002Additional 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 Environment—2002Total 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 Migrationsto the New Environment—Part 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**
**Grant Images copied to ES40-SAN (Ramesh)**
**To be opened up to developers and testers on **_**12/11/01**_

## Progress on Database Migrationsto the New Environment—Part 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**_** **
