All actions below should be applied to each ESXi server.

We’ll also migrate your workloads at no extra cost.ĭramatically decrease your CapEx, OpEx, and IT management costs, while visibly increasing return on investment (ROI) with hyperconvergence for ROBO, SMB & Edge from StarWind. Everything’s operated through a neat web UI. All your systems will be “babysitted” by StarWind 24/7/365, troubleshooting any concerns without your involvement.

You don’t need anything else to build a budget-friendly new IT infrastructure or upgrade an existing one.

StarWind HyperConverged Appliance is a turnkey hyper-converged hardware platform fitted into a small two-node footprint. Synchronization and iSCSI/Heartbeat links can be connected either via redundant switches or directly between the nodes. NOTE: Do not use ISCSI/Heartbeat and Synchronization channels over the same physical link. On each node, network interfaces to be used for Synchronization and iSCSI/StarWind heartbeat should be in different subnets and connected directly according to the network diagram above.

StarWind VSAN should be installed on the Windows Server operating system deployed as VM on each host.ģ. ESXi hypervisor should be installed on each host.Ģ. The diagram below illustrates the network and storage configuration of the solution.ġ.
#VMWARE VSPHERE 6.5 FAULT TOLERANCE SOFTWARE#
NVIDIA GRID is architected with a software model which gives us the ability to add additional support for new OSs for customers existing hardware allowing them to pick up new features. We all know what you want and what you want our priorities to be!!! NVIDIA and all the partners such as Citrix and VMware appreciate that live motion and snapshotting are key enterprise datacenter needs so we continue to work towards making such technology happen (it’s very technically hard I’m told!). This is also a pre-requisite for live migration/motion e.g. No not today, the technology to continually essentially snapshot a live GPU is not available. So is Fault Tolerance (FT) supported for vGPU? It’s a feature essentially only used in a few safety / mission critical use cases as it’s so costly to implement. milliseconds behind), in the event of failure the user is switched to the duplicate with only a momentary glitch in user experience. Many hypervisors though offer Fault Tolerance (FT) which can provide such support, this is a very expensive feature to use as it relies on running essentially a duplicate VM on mirrored hardware which is phase-locked to the original (i.e. It is a feature VMware could add in the future though if they saw sufficient demand, it is not a feature engineered by NVIDIA. I believe that VMware’s configuration does not extend to configuring GPU resource reservation and so the support announced today will not offer guaranteed HA. maybe 15% of a hosts capacity, which allows a guarantee that resource will be available to restart VMs upto a certain number of host failures. This can be provided by HA features by allowing resources to be resourced such as RAM/CPU on hosts e.g.

Although the user will experience some down-time where possible this is minimized without the need for manual intervention by a system administrator. So for vGPU enabled VMs that means on a host with an appropriate GPU etc. The VM will automatically restart as soon as possible on another host if one is available with sufficient resources. What is High Availability (HA)?īasic HA is a feature to ensure VMs are up and running as soon as possible in the event of host failure. Probably best to answer a few basic questions straing away.

I’ll update this blog with links to the documentation when it becomes available which should be soon!īut since Pat has let the cat out of the bag…. I think there have been a few problems with the documentation update staging which is why this has been a rather quiet feature release. As a VMware implemented feature this was something we at NVIDIA had to wait for them to announce. It’s something we knew VMware had added to vSphere 2016, vSphere 2016 supported in the GRID 4.1 (Nov 2016) release. I was very pleased yesterday to see Pat Lee from VMware’s PM team tweet about this yesterday…
