Hi, I'm wondering what kind of hardware you are using if you're using TSM Dedup facilities (client and/or server) ?
Can you fill the following fields : - Total data in dedup pools (Native/Deduped) - Total data ingested daily (Native, server side/Deduped, client side) - Size of your DB - Do you backup your STG to Tape ? - Disk subsystem for DB ? - Disk subsystem for Active Log ? - Opinion on that disk subsystem ? Enough, too few ? Here's an example from one of my customers - Total data in dedup pools (Native/Deduped) : a bit less than 10 TB (logical_mb), 21,5 TB (reporting_mb) - Total data ingested daily (Native, server side/Deduped, client side) : 1 TB (native), no client side - Size of your DB : 220 GB - Do you backup your STG to Tape ? Yes, to LTO4 - Disk subsystem for DB ? 2*RAID1 15krpm (4 internal disks), 2 volumes, 2 directories - Disk subsystem for Active Log ? 1*RAID1 15krpm (2 internal disks) - Opinion on that disk subsystem ? Disk for DB are 100% busy most of the time (expire inventory, reclaim stg...) I think adding two more disks (one RAID1) to the DB would be really effective. Your turn now ! Thanks a lot. -- Best regards / Cordialement / مع تحياتي Erwann SIMON
