      This probably has nothing to do with it, but how is the shared storage configured? Are there multiple I/O paths, or is there a single partitioned share that could bottleneck access to the storage?

        Hrm, how did you create the clones?

        SAN IOPS still solid?

        That's a lot of CPU for VM machines, are you getting scheduling conflicts with processor time?

        Those were the first things I thought of at least.

          There are multiple storage paths. Each NIC in the VM connects to a different physical NIC in the VMware host.

            Could it be that I need to manually set the interface metric -- to force one to always be master?

              Hrm. . .

              Are you using the RDP connection option from within XenCenter to connect to these systems? (still investigating the shared resources item mentioned above.)

                This is running on VMware. 🙂

                We are connecting to them via RDP and the VMware console. Neither makes any difference.

                  SAN IOPs are still good. We're barely even touching the SAN (this is a security camera system that's not in production yet).

                    Yeah I realized I was a few minutes behind the ball after posting. So ignore me.

                      Got an oddball problem here... We are working on setting up several VM clones for a project here. Each VM will be connected to the same shared storage via iSCSI.

                      Under the hood, right? Via the datastore, not iSCSI connecting to the OS inside of the VM, right?

                        No, we don't have anything running on them yet. The iSCSI initiator service is the only thing that has been set up, and our usual disable IEC, and UAC type stuff.

                        Otherwise, it is a basic Server 2012 R2 install.

                        Why use iSCSI from inside of the VM?

                          Why 4 vCPU each? That seems excessive.

                            Given the setup, my inkling is that you have an issue with the iSCSI Initiator. The Microsoft iSCSI Initiator is known to be flaky and can easily be causing an issue. Both architecturally and practically due to the use of Windows it is standard practice to present SAN storage as a local drive via VMware to the VM rather than inside of the VM. VMware's handling of iSCSI is much more robust than Windows is, and you need only one connection per physical host rather than one per VM.

                              Agreed. We don't expect the software to use that much, but we're building it to the specs that our vendor has requested.

                                With virtualization that can cause performance problems. The vendor may be injecting a mistake here. Having more cores than are needed will degrade performance. And... can cause lockups in rare cases.

                                  That's the way I would set it up. Although this time, I'm actually not the one who set up the master image. We're connecting to a SAN to store large amounts of video for security cameras.

                                    Well it doesn't work well that way and in this case, it's possible that it doesn't work at all 🙂

                                      I'm not questioning the SAN or the iSCSI. I'm questioning the configuration which is extremely complex and fragile compared to a more elegant, more modern configuration using VMware as designed.

                                        I've set up shared storage with VMware before, and IIRC, isn't there a limit on the size of the disk image that you can set up? Our VMware disk images would be ~20 TB each.

                                            Cool. I'll pass that info along and see if he wants to set it up that way.
