We are using an IBM3584 and don't use any kind of collocation. We have found the migration process from diskpool to tape collocates data by node and therefore already does a decent job of grouping node data together.
The only time you may see better performance with collocation is with a server that has alot of little files that change often and those nodes should probably be stored on VTL or DISK rather than tape. +---------------------------------------------------------------------- |This was sent by jeff.je...@sentry.com via Backup Central. |Forward SPAM to ab...@backupcentral.com. +----------------------------------------------------------------------
