Description
Different virtualization techniques are in use at the DESY data centers,
with Xen servers being the dominant hypervisor. Besides its open source
implementations, DESY, location Hamburg, has set up a pool of DELL
servers with NetApp storage and Xen Enterprise software to provide a
highly available, scalable, and versatile environment for manging data
center services on various Windows and Linux flavoured operating systems.
The system currently supplies 90 paravirtualized servers on 18 dual CPU
servers.
We will provide an overview of the implementation, its integration with
installation services and storage systems, use of features like HA,
Snapshotting, Ontap connection, and central administration.
We will present advantages and limitations of our approach and our recent
upgrades to the pool.
