13 ANNUAL REPORT EKT
EKT’s e-infrastructure comprises:
Datacenter
With usable Datacenter space of over 100
square meters and an emergency generator
power supply of 550KVA.
It features extensive Green IT facilities, such
as a Cold Isle Containment system and an
automated system for monitoring, logging and
improving the Power Usage Effectiveness (PUE)
of the Datacenter.
Virtualisation platform

servers for minimizing financial and
environmental resources used.
Physical systems
• 49 enterprise grade x86 servers,
• 3 Storage Area Networks with 86Tb capacity
• one Free Open Source Software Cloud
based storage system, with 36Tb capacity,
based on commodity hardware
• tape library based backup systems with
over 120Tb of capacity
Flexibility and minimized
Total Cost of Ownership
