Hi my situation:
Windows 2003 Standaard (SP1) - Arcserve 11.5 and LTO2 IBM Ultrium-TD2 (firmware 53y3) Powervault 136T and latest firmware....
what is the optimal Blocksize for the LTO2 drives. i think 256KB.
now i found this article on the microsoft site : http://support.microsoft.com/kb/907418/EN-US
it is about performance limitation after installing SP1 on windows 2003 server. it is about the tape.sys.
my question: does this fix have any effect on arcserve, because all devices are disabled in system manager even the media changer. and the fix is for Tape.sys (i think meant for NTBACKUP)
how can i tune my server for high(read better) backup performance. my average backup speednow is 500-1100Mb/Min, and when i calculate, native for LTO2 (IBM) = 35MB/sec = 2100MB/min
I had DLT 8000 with 6MB/Sec native, my backup speed on exactly the same server was 350 MB/Sec.
what can i do about is..
can i do some registry change like i did for DLT for this LTO2 issue.
what are your experiences......
(sorry for my bad english..)
