Respected forum members,
This is my first ever thread. I have tried to make it as informative as possible.This blog is inspired by Curtis Preston's blog .http://searchdatabackup.techtarget.com/tip/Tape-backup-best-practices-How-to-improve-tape-storage-performance but not copy/paste job.I have used only headings from that article.
Tape is not going to go away as much as I like to throw it out.So to get best out of Tape drives in Netbackup based environment with Disk staging,please have your Architect hat ON and procced furthur.
Understand the limits of your tape drive
LTO-4 tape drive's maximum native (uncompressed) transfer rate is 120 MB/s. LTO-4 Drives we used had about 128MB of SRAM as cache. More data you are able to send to the drive cache more faster your drive is going to perform.
Below table gives you speed and capacity numbers for each LTO drive type and media.My goal was to achive 240MB/s in my environment...
