## About the Role

* Expertise approfondie en environnements Unix (AIX constitue un atout majeur ; Linux RHEL/Alma aprecies) et bonne maitrise des ecosystemes serveurs de type LPAR/virtualisation ; la connaissance du stockage SAN (Pure Storage) et des outils de sauvegarde (type Spectrum Protect/TSM) est attendue.

Missions

 * Realiser un audit de l'existant et une etude comparative (TCO, performance, scalabilite) pour identifier les solutions de remplacement adaptees.

 * Concevoir les architectures cibles (virtualisation, partitionnement, stockage, composantes cloud) et piloter les phases de Proof of Concept.

 * Preconiser une solution technique argumentee et assumer les impacts operationnels associes, en lien avec les equipes d'architecture et d'administration en place.

 * Garantir l'integration native des briques de stockage, de supervision et de sauvegarde dans le nouvel environnement, incluant la definition et la validation de la strategie de reprise d'activite (PRA).

 * Anticiper les impacts sur les couches applicatives et middleware, et elaborer la strategie de migration.

 * Assurer le transfert de competences aupres des equipes internes et produire la documentation technique associee.
