Try running an FTP to get network performance without TSM. Then try running a selective backup of one big file (like 1 or 2 GB) to eliminate client processing.
13,3 Mb is megabits. -----Original Message----- From: Henrik Wahlstedt [mailto:[EMAIL PROTECTED] Sent: 06 March 2003 15:38 To: [EMAIL PROTECTED] Subject: Re: Poor TSM Performances It looks like the NIC settings arent 100/full duplex om both systems and switch. How did you calculate 5,84GB/Hour => 13,3 Mb/sec ? If you do it backwards 13,3 MB/s * 60sec * 60min=47,88GB/h. //Henrik Ruddy STOUDER <[EMAIL PROTECTED] To: [EMAIL PROTECTED] SLINK.COM> cc: (bcc: Henrik Wahlstedt) Sent by: "ADSM: Subject: Poor TSM Performances Dist Stor Manager" <[EMAIL PROTECTED] EDU> 2003-03-06 15:07 Please respond to "ADSM: Dist Stor Manager" I am quite disappointed by the TSM software performance. Let's take : WIN2000 client, Bi-Pro, nothing running on the machine except TSM client WIN2000 server, Bi-Pro, nothing running on the machine except TSM Server Client is backing up to server, using 100Mb TCP/IP => Throughput of 5,84GB/Hour => 13,3 Mb/sec !!! With LAN-Free, result are the same !!! So, having machines with CPU used with less than 10%, LAN card used at 10%, where is the bottleneck ? Backing up to disk or to LTO tapes does not help increasing the performance. Following parameters are set : TCPBUFFSIZE=128 TCPWINDOWSIZE=63 TCPNODELAY=YES (AND TESTED WITH NO) LARGECOMMBUFFERS=YES (AND TESTED WITH NO) I was hoping to reach at least 25GB/Hours via a TCP/IP 100Mb network and 50GB/Hours via LAN-Free to LAN device Many thanks in advance for any feddback Ruddy Stouder Senior Technical Consultant TSM Certified Consultant I.R.I.S.
