You said you've checked NIC but don't provide details. One thing that we've seen as a common problem is networking. On HP-UX the 100 MB cards MUST be hard set to 100 Full as must the associated switch ports. They do NOT autonegotiate properly. (For Gigabit ethernet both sides have to be autonegotiate.)
Also to try to eliminate backups being impacted by regular traffic (and vice-versa) you might want to consider having dedicated NICs for a backup LAN. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Espe, Thomas Sent: Wednesday, October 10, 2007 9:33 AM To: veritas-bu@mailman.eng.auburn.edu Subject: [Veritas-bu] Problems with network speed (NBU 6.0MP4) Hello. We are experiencing problems with the network speed on one of our NBU media servers. This is an HP-UX 11.23 server running NBU 6.0MP4. We have tried tuning the server following the guidelines in the 'Backup Planning and Performance Tuning Guide' for NBU 6.0. We have also checked the network settings on the NIC and on the switch, to no avail. We find this strange, as we have our NBU master/media server (Linux) on the same switch and this server is getting up to 9-10 times faster data transfer as the media server does. Has anyone run into similar problems? Any hints on how to proceed? -- Sincerely Thomas Espe _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu ---------------------------------- CONFIDENTIALITY NOTICE: This e-mail may contain privileged or confidential information and is for the sole use of the intended recipient(s).
