Plan to virtualize further Grid Services deployments using Microsoft Hyper-V
Regarding migration to EMI/UMD, no work yet, but would prefer to have access to some installation and maintenance recipes supported by developers (similar to what does exist for gLite).
Topic: Protected_Site_networking
- Tier1 is a subnet of the RAL /16 network
- Two overlaid subnets: 130.246.176.0/21 and 130.246.216/21
- Third overlaid /22 subnet for Facilities Data Service
- To be physically split later as traffic increases
- Monitoring: Cacti with weathermaps
- Site SJ5 link: 20Gb/s + 20Gb/s failover direct to SJ5 core two routes (Reading, London)
- T1 <-> OPN link: 10Gb/s + 10Gb/s failover, two routes • T1 <-> Core 10GbE • T1 <-> SJ5 bypass: 10Gb/s • T1 <-> PPD-T2: 10GbE
- Limited by line speeds and who else needs the bandwidth

Memory
1. Real physical memory per job slot:
All WNs have 2GB/core (1 job slot per core).
2. Real memory limit beyond which a job is killed:
Dependent on queue : 500M,700M,1000M,2000M,3000M
3. Virtual memory limit beyond which a job is killed:
no limit
4. Number of cores per WN:
4 or 8 depending on hardware.

Network
1. WAN problems experienced in the last year:
2. Problems/issues seen with site networking:
3. Forward look:
Plan for doubled 10GbE (20Gb/s) for internal links and doubling of existing links as needed.
