2. An overview of the infrastructure

3. Cnt…

4. To simplify administration…
The rule of thumb is that we offload as many services as possible to the University IT Services
Examples of services planned to be provided by the University
Firewall
DNS
Wiki
ZMS based web page
Please notice that the University has a large number of services provided by the
IT Services Department (ID)
iLUB team (Ilias)

5. Network Infrastructure provided by ID/Institute (right rack)
Two switches provided by the University
/25 (will be shortly managed by CDS)
/25 (will be shortly managed by CDS; no firewall!)
/24 (Peppo Brambilla)
/24 (Peppo Brambilla)

6. Physical Infrastructure of the CDS Group (left rack)
Dell PowerEdge R520 (Used as a CDS XEN server)
32 threads, 192 GB RAM (16 cores, 2 sockets)
Dell PowerEdge R530 (Used as an OpenStack compute node)
48 threads, 192 GB RAM (24 cores, 2 sockets)
Dell PowerVault
~10 TB HDD Storage
Dell N4032
24 10 GbE-T ports each
2 40 GbE stacking ports each
Two auxiliary PCs used for the OpenStack installation
Mirantis Fuel node – deploys OpenStack automatically (controller, compute node)
OpenStack controller node
SSD disk for handling images
Use the current infrastructure. Deploy physical machines only if permission is granted by Prof. Braun or a responsible person!

7. Storage PowerVault MD3800i (Service Tag: HM80S12; Express Service Code 38349028838)
Management Interfaces:
iSCSI Interfaces:
SAS-600GB
5 hard drives in RAID 5
1 hard drive as hot spare
SAS-3TB
5 hard drives in RAID 6

8. XEN Server (Service Tag: G2T3S12; Express Service Code: 34998334886
Supposed to run stable infrastructural deployments supporting the group
Etherpad FP7 MCN Project
Git FP7 MCN Project
Management IP:
XEN-Server has access to
/25
/24
Access To Storage:
IDRAC:
Old Wiki
Jira FP7 MCN Project
Nagios
OwnCloud FP7 MCN Project
Subversion
Teampass
DNS Server

9. OpenStack Installation
Please ask for login / password
Deploy reasonable computing MAX 48 threads, 192 RAM, shared with others!
The infrastructure is foreseen to run research / unstable deployments for the group members.
If the OpenStack environment breaks, it can be redeployed by Mirantis Fuel
Mirantis Deploys a useable OpenStack, but some configuration options shall be introduced manually, e.g., connection to PowerVault
Don’t use password authentication on your VMs!
(IDRAC), , , , ,
131 – was fuel, but disconnected at the moment due to security reasons…
136 – 254 allocation pool for VMs for the CDS group members (floating Ips)

10. Teampass.cnds.unibe.ch
Team-based password management system for the CDS Group
A VM hosted on XEN-SERVER with the IP address

11. NAGIOS Monitoring System
A VM hosted on XEN-SERVER

12. Ilias CDS Group.

13. New Webpage of the CDS Group

14. Netadmin of the University
- list of university management tools
– list of responsible persons for networks
Firewall
Management of all the Institute Networks
/24,
/24
Management of the University DNS server for domains
unibe.ch
inf.unibe.ch
iam.unibe.ch
cnds.unibe.ch (to be migrated)

15. Netadmin screen-shot

16. TODO LIST The backup system
We consider hybrid (proprietary/opensource) software solution together with Peppo Brambilla
Static backup on NAS of the institute
LDAP of the institute for all accounts (incl. guest OU) [deadline ]
Gitlab managed by the Institute
Migration of our SVN to GIT of the Institute
Nagios monitoring at the Institute Level
Merge our monitoring system with the system of the Institute (physical machine)
