Tapes and Staging

We are expecting to be able to remove all the TA90 cartridge drives from the Cluster. The only tape drives remaining in the Cluster will then be those in the Exabyte robot, currently used for backup/restore. All user tape access will thus be through the TPREAD/TPWRITE/RFIO chain being developed by F.Hemmer under the CORE umbrella. This will require (and obtain) a substantial increase in the size of the disk$stage pool on VXCERN. System backups will continue to be done using the Exabyte robot, and there are plans to offer some user slots in this device, if it can be moved to the Vault.
