19 production DS20E
4 non-production servers
Migration (2010)
Migration Step 1 :
Move the 19 DS20E to the SPIE headquarters.

Step 2 :
Clone Windows 2k3 from the master copy on the 12 Dell R610 and install Charon-Axp license keys.
Step 3 :
Backup the non-O.S file systems from the actual DS20E and restore them on the Charon-AXP corresponding file systems
Step 4 :
Turn off the old DS20E.
Migration (2010)
Low hardware maintenance (up-to-date hardware with 3 year warranty).
Less servers to manage => less space/electrical consumption/cooling.
Performances and stability enhancement.
Easy to update : add/upgrade CPU, SDRAM, disks or change server.
Quick migration : no rewriting and qualifications tests for applications and processes.
No change for application users, developers and Unix administrators.

Benefits of Charon-AXP
What’s next …
ES40 evolution (1 more CPU and 4GB SDRAM).
Improve the Disaster Recovery Plan.
SAN tests for better I/O performances.
