Folks,
I'm hoping someone can point me in the right direction here. We've been running VMware Server 2.x for a few years and decided to upgrade to vSphere5.1. We rented a rackmount HP server and built out several of our development and staging servers to properly evaluate issues and set performance expectations. We've since migrated our servers to a new platform with 3 hosts, SAN storage, GbE switches,etc. Several of our development server VMs are now running slower on the new host servers than they did on the rental host server with vSphere5.1 Evaluation license. One VM in particular is configured as follows:
vmx-09, 1 vCPU, 2GB vRAM, vHD1-75G, vHD2-75G, vHD3-20G, vHD4-20G (all thin provisioned), SCSI Controller - LSI Logic SAS, 1 vNIC (E1000), default video card, Guest OS: Windows Server 2008 R2 running SQL Server Mgmt Studio 2008
OLD host server(rental - running vSphere5.1 Evaluation license:
1 x HP Proliant DL380 G6, 2xIntel Xeon X5650 6c 2.665Ghz, 64GB RAM, 10x300GB 15k SAS internal drives - 5 RAID1 volumes - 5x279GB datastores, 2 active 1GbE NICs on separate subnets
NEW host server (permanent server running vSphere Essentials Plus license):
3 x Dell PowerEdge R420, 2xIntel Xeon E5-2440 6c 2.4Ghz, 96GB RAM, Compellent SC8000-based multi-Tiered iSCSI SAN (15k RAID10 & RAID5, 7.2k RAID10 & RAID5), 6 active 1GbE NICs on GbE switches
This VM (like the several others showing same behavior) performed on rental server with no noticeable lag or slow downs except under heavy development load. Now on new server environment VMs show lag during login, general browser functions, opening apps, etc. Delay has gone from 1 second to open app to 6-8 seconds to open same app. Development load went from 2-3 minutes to 11-15 minutes. vSphere performance tab shows no high mem, cpu, network or disk usage. Guest OS shows no high usage on these resources either yet lag in all aspects of guest OS usage continues.
Suggestions on where to check and what information to collect are all welcomed.
Thanks.
