The VOMS and the SE in Tier 2 Presenter: Sergey Dolgobrodov HEP Meeting Manchester, The VOMS and the SE in Tier 2 Presenter: Sergey Dolgobrodov HEP Meeting Manchester, January 2009

What is VOMS • VOMS is… – An Attribute Authority. – A VO Management What is VOMS • VOMS is… – An Attribute Authority. – A VO Management System. – A source of trust for authorization. • VOMS is not… – A policy system. – An Auth. N/Auth. Z framework.

VOMS: The problem • In a grid environment, VOs tend to be extremely large VOMS: The problem • In a grid environment, VOs tend to be extremely large and change frequently. – Hundreds or even thousands of users. • Sites need to know the users because of the need to prepare local accounts and eventually apply authorization policies. • It is not scalable to manage them by hand

VOMS: The solution • Organize users into groups and grant them roles. – Allows VOMS: The solution • Organize users into groups and grant them roles. – Allows for full Role Based Access Control authorization. • Also, adds other general-purpose attributes.

DPM, d. Cache, SRM what are they • Storage Element: DPM and d. Cache DPM, d. Cache, SRM what are they • Storage Element: DPM and d. Cache – disk caching front end – End user interface to write and read cached files • Storage Resource Manager – Provides a consistent interface to underlying storage systems.

Tier 2 SE • Combine hundreds of commodity disk servers to get a huge Tier 2 SE • Combine hundreds of commodity disk servers to get a huge terabyte scale data store • Storage site gains increased fault tolerance • Allows several copies of a single file for distributed data access • Internal load balancing using cost metrics and transfers between the site's pools • Automatic file replication on high load (d. Cache)

Manchester Tier 2 SE • Combines about 160 TB of disk space on 900 Manchester Tier 2 SE • Combines about 160 TB of disk space on 900 nodes • Maintained and monitored around the clock • Upgrading and tuning annually

This year plans • New storage hardware installation • Migration from d. Cache to This year plans • New storage hardware installation • Migration from d. Cache to DPM • Improving and tuning of the DPM/d. Cache performance via configuration • Monitoring and automation of the cluster maintenance including SE's, Computer Elements VOMS etc.

Thank you Thank you

VOMS data format • Attributes (groups, roles, general purpose) returned by VOMS are inserted VOMS data format • Attributes (groups, roles, general purpose) returned by VOMS are inserted into an RFC-3281 compliant Attribute Certificate. – The exact profile is described here: • https: //forge. gridforum. org/sf/go/doc 13797? nav=1 – ACs are the natural choice in a X. 509 world. • The grid is a X. 509 world. • The provided clients insert the AC in a non-critical extension of the user proxy. – Immediate compatibility with non-VOMS aware software.

What is a proxy? • A proxy is a short-lived certificate that has as What is a proxy? • A proxy is a short-lived certificate that has as issuer a user certificate. – Standardized in RFC 3820. – Commonly used throughout the grid for authentication and authorization purposes.
