List of experiment requests for high level tools

In this page we list the requests coming from the experiments on high-level tools to be able to fully use the capabilities offered by the storage services that provide an SRM v2.2 interface. For each request we also list in which version of the Data Management high level tools the request has been satisfied.

GFAL

  1. Expose request IDs to users
  2. Provide thread-safe calls
  3. Extract VO from proxy

lcg-utils

  1. Allow for bulk operations at CLI (input can be provided through an input file)
  2. Provide a CLI for stage, pin and release operations
  3. Provide an explicit switch to turn off operations on LFC
  4. Make checksum/checksum type available in Ls after file has been written to tape
  5. Extract VO from proxy
  6. Provide thread-safe calls

FTS

  1. Allow for space tokens, pinning lifetime and file storage type to be specified for both source and destination

Requirements on the storage services

  1. Storage services should allow for directories with ~10K entries (this requirement comes from ATLAS; CMS and LHCb have requested support for only ~1K entries) without performance penalization.
