Sure thing: 1) The VMWare environment is connected via 8Gb fibre to an EMC VNX 5700 and uses mostly tiered storage pools (SSD-SAS), The TSM server is connected to a V7000 via fibre as well. The TSM database is on SSD and the storage pools are on 84 NL-SAS disks in a RAID6 extent pool provided by the V7000. The TSM server has a LACP nic team consisting of two 10 Gb adapters. Each ESXi host has either dual 1Gb NICs or dual 10Gb NICs assigned to the management VKernel port. 2) The stated rates in my previous post are for IFIncremental traffic, be it a fresh full or a subsequent CBT incremental backup. 3) The VMware client is 7.1 and the server version is 6.3.4.200.

Sent by: "ADSM: Dist Stor Manager" <ADSM-L@VM.MARIST.EDU> Hi Matthew Can you tell us some more about your infrastructure? What kind of disk storage network are you using? iSCSI? FC? block-data? NAS? Are your stated rates for image backups, or file-level incremental? What version of TSM are you using?
