Thin Client Environment

Secure x Design

1.1                    Server Architecture

1.2                    Scenario 1 >>>>>> Server down

Description:  This could be due to failure in the Citrix farm Data Base, or H/W failure.

Impact: Medium. It will be impact all Thin Client users, but it will cause minor performance degradation of application published on Citrix. 

Probability: Low, as we have redundancy in DC & DR. Please refer to Fig.1 in 9.1

BCP: There are 70 virtual Citrix farm servers in DC, and another 70 in DR. These servers are on two high end redundant physical servers and 5 smaller servers in DC, one high end and 7 smaller physical servers in DR.

If we face DB failure, the last server snapshot will be restored.

If we face H/W failure, we will depend on the redundant servers, and restore the faulty server as per the maintenance contract and the SLA with HP.

RTO: 1 Hours to restore the DB backup.

          6 Hour to replace the faulty H/W part
