Rosset : Estate Agency


Rosset Immobilier is a family run company founded in 1957 and is currently managed by Gérald Rosset and his son, Thierry Rosset. It has about a hundred and twenty employees mainly based in Geneva and distributed over 3 geographical sites.

Challenges faced by client


  • Client would like to keep their IT infrastructure and datacentre on their own premises.
  • Centralise data to a single geographic location
  • Maintain an IT system which is always available in the event of a major IT failure
  • Incorporate a solution compatible with different business applications and the virtualized infrastructure which is in place
  • Archive data to meet legal requirements
  • Align IT with ISO certifications conditions (9001 :2008 for their lease management activities for all buildings, isolated plots, residential and PPE administration cooperatives)


Solutions implemented:


Thus, to meet the different expectations of Rosset Immobilier (Estate Agency), Codalis has restructured the existing architecture to simultaneously address issues related to backups and the need for a DRP solution.

To ensure IT infrastucture availability, we developed a secondary site in Codalis’ Datacentre. The solution is a backup site which enables users to continue their activities in the event of an IT failure on the main site.

An additional backup system is installed locally to ensure backups in the allotted time slots.
A solution which enables at the same time high volume and rapid restores, targeted backups, targeted to specific resources such as a file or email.

a single technological solution is deployed to cover all needs.

Codalis provides a complete software, harware and network solution.

The technical environment is based on the following technologies :

  •  VMware ESX 5.x
  • Windows 2008 R2, Windows 2012, Linux Suse
  • SQL Server and Oracle Database
  • Exchange Server, file servers and Citrix XenApp
  • Veeam Backup & Replication Solution
  • DELL and EMC solution
  • Réseau WAN MPLS

Rosset Immobilier (estate Agency) can confidently understand its evolution including the relocation of its central site effective since August 2015.
