The copy starts really fast (200MB/sec), but after a minute or so, the speed drops to 12MB/sec: Secondly I installed a clean Windows 2012 standard server on the ESXi 5.1 and started a copy from datastore1 (RAID1) to datastore2 (RAID5). The problem we are having is, I think, related to ESXi 5.1 in combination with the H310 controller:įirst I copied a file using fastscp with veeam: Installed latest firmwares trough the Dell Lifecycle controller. Installed ESXi4.1: copy speed over fastscp 50MB/sec, but stable. Installed a Windows Server 2012 Standard directly on the physical server (so no esxi): NewServer performs perfect, copy speed over network 100MB/sec, copy speed from RAID1 to RAID5 +200MB/sec Performed an extended Dell Diagnostic test: all tests passed The following tests have been performed on NewServer: It has been clean installed with an ESXi 5.1, but not in production yet, so I can test whatever I want. We are having performance issues on our NewServer. Switch: Cisco Catalyst 6509 (no vlan's configured in this setup)
